The Bicycle Guide to GTO Poker Simplified Strategy lessons from the solvers that any cash game or tournament player can apply to their game

1. 1Set the inputs first: stack depth, position, pot size, and the tendencies of the table. Of these, the book says to adjust from the GTO baseline mainly on your read of how often you will be 3-bet, which matters more than how tight or loose opponents look.
2. 2Set your opening width by the number of players left to act. UTG opens tightest because it has a whole table to get through. The Button opens much wider because only two players remain and it acts last on every street. Do not open every hand in your range, especially from early position.
3. 3Cut the hands that only get you in trouble when deep. At 100 big blinds from early position, muck ATo and KJo, because deep stacks need a very strong hand to stack off.
4. 4Hold the percentage fixed and swap offsuit hands for suited ones. One offsuit hand is 12 combos and a suited hand is 4, so folding one offsuit hand frees room for three suited hands without changing how many hands you play.
5. 5Fill the suited slots with hands that cover the board. Suited Aces such as A5s, A4s and A3s block part of the opponent's calling range, make flush and wheel draws, and make top pair when an Ace hits. Against a 3-bet, trade a dominated hand like ATo for these.
6. 6When defending against a 3-bet, find the required defence frequency first (15.21% in the book's example). Then pick the hands that reach it with the best board coverage, not the best raw showdown value.
7. 7Check the coverage in your final range. Ask whether you can have trips on a paired flop, strong draws on a wheel flop, and bluffs on a flushy flop. If one texture is empty, change a hand to fix it.
8. 8At low stack depths, widen your shoving range against late-position openers. A 20-30 big blind shove adds 20-25% to your stack when it gets through, and late-position players fold more.
9. 9Skip limping in your baseline. GTO limping ranges are complicated and add few hands, so a 100% open strategy is simpler. Use charts as a baseline and deviate on table tendencies.

The book's example is a 3-bet defending range where you must call 15.21% of the time to avoid being exploited. ATo looks natural, but it is usually dominated by a 3-betting range, and its main hope is two pair. Fold the 12 ATo combos and play 4 combos each of A5s, A4s and A3s instead. The percentage of hands played is unchanged, since 12 combos replace 12. Coverage improves. On a 33J flop you can hold trips, and on a 3♦2♣Q♣ flop you have many profitable bluffs with wheel draws and flush draws. Because the suited Aces block part of the opponent's calling range, they also take the pot down preflop more often as bluffs. ATo has far fewer ways to win a big pot.

• If a hand is offsuit, dominated by the opposing range, and hopes only for two pair, replace its 12 combos with three suited hands (4 combos each) that cover wheel and flush boards.
• If you are in early position or deep-stacked, tighten up and cut hands like ATo and KJo. If you are on the Button, widen, because only two players remain and you are last to act.
• If you expect more 3-betting than usual, tighten your opens and punish habitual 3-bettors with good hand selection. If the table is timid and passive, open more hands.
• If stacks are shallow (20-30 big blinds) and the opener is in late position, shove more, because the fold equity is high.
• If chart ranges conflict with your table read, use the chart as a baseline and shift your range toward what the table's tendencies reward.

• Choosing hands by showdown strength alone, such as ATo or KJo, and keeping dominated offsuit hands. Tell: you make second-best top pair or two pair and lose big pots.
• Building a range with nothing for wheel or flushy boards. Tell: you have no good bluffs or trips on boards like 3♦2♣Q♣ or 33J.
• Opening every hand from early position. Tell: you get 3-bet often and cannot continue profitably, especially at shallow depths where shoving is stronger.
• Following charts like a cookie cutter. Tell: you ignore a table that 3-bets too much or too little, and you give up the value from adjusting.
• Expanding the range by a feel for hand count instead of combos. Tell: your range is wider than you intended because you did not count 12 offsuit combos against 4 suited ones.

• ▸Spot: position, stack depth and pot size, so the baseline is clear.
• ▸Table read: expected 3-bet frequency (more, less or normal) and whether to tighten or widen from baseline.
• ▸Target frequency: the percentage you must open or defend, such as 15.21% against a 3-bet.
• ▸Weakest offsuit hands: the dominated offsuit hands you plan to cut, with combo count (12 each).
• ▸Suited replacements: the suited hands to add and their combos (4 each), checking the totals match.
• ▸Blocker value: which opponent calling hands each added hand blocks.
• ▸Coverage check: whether the range has trips on paired boards, draws on wheel boards, and bluffs on flushy boards.
• ▸Shove range: hands to shove at 20-30 big blinds against late-position opens.
• ▸Review note: any hand that behaves unlike the rest of its group, and why.

1. 1Name the objective before the size: value extraction, equity denial (bet so weak hands fold and can't catch up), semi-bluff, or check to protect. The UTG flop example shows each hand class in the same range gets a different job.
2. 2Sort your range into value hands, bluffs, and checkers. Check strong-but-vulnerable hands that would only be betting into Ax or better after weaker hands fold. KK-TT on the UTG flop are the example: they turn into bluff catchers by checking.
3. 3Set the bluff share from the size. Calculate what the caller risks against what they win: $25 into $100 is 25 to win 125 (5-to-1), so they need to be good about 17% of the time. $100 into $100 needs about 33%. Your bluffs should make up roughly that share of your bets.
4. 4Convert that share into a count. A pot-size bet supports about one bluff per two value bets. A quarter-pot bet needs about five value bets per bluff. If you hold few bluffs, the small size is the one that fits.
5. 5Pick the large size for hands that gain from folds or want money in when called. 77-44 bet to deny equity, and 44 and 55 bet bigger and more often because they can turn a straight and are happier building a pot when called. Hands that gain nothing from folds, like AA, check often.
6. 6Mix, don't pick. If the solver bets a bluff 40% and checks 60%, play both at those frequencies. Always bluffing over-bluffs and always giving up under-bluffs. Use a hand-based rule such as flush-draw or backdoor-draw suits to choose which hands fill the betting slots.
7. 7Read solver output for the high-frequency actions only. Ignore sizes used under 5% (the 1.47% bet of 66 in the book). When two similar sizes are mixed, like 10 and 18, treat them as one 'small bet'.
8. 8Check the inputs and the opponent. A solve is only as good as the ranges and bet sizes you assume. Against a calling station, deviate: bet more value hands and use bigger sizes instead of protecting a small-bet range.

You hold a pot-size bet's worth of decision in a $100 pot. A $100 bet makes the opponent risk $100 to win $200, so they need to be good 33% of the time. Your betting range should be about one-third bluffs, or one bluff for every two value hands. With three value hands per bluff you under-bluff, and they fold their bluff catchers freely. At 50/50 you over-bluff, and they can call or reraise light. Now bet $25 instead. They risk $25 to win $125, need about 17%, and call wide, so you need five value bets per bluff. The sizes aren't interchangeable, because each demands a different range. On the UTG flop from the book, the solver applies this by hand class. KK-TT almost never bet because a bet folds out the weak hands and leaves them against Ax or better. 77-44 mostly bet, some at the big size, to deny equity: checking 77 lets a 9 turn and J9 catch up after folding to anything on the flop. 44 and 55 bet bigger and more often because they can turn a straight.

• If you hold few bluffs or your range is heavy with value, then use the smaller size, which needs fewer bluffs (about 1 in 6). If you have plenty of bluffs and equity-denial hands, the larger size (about 1 in 3) fits.
• If a hand is strong but a bet only folds out hands it beats and keeps hands that beat it (KK-TT on the UTG flop), then check and let it be a bluff catcher.
• If a weak hand loses a lot when the opponent catches up on later streets (77 facing a turn 9), then bet to deny equity. If it also has straight outs (44, 55), bet larger and more often.
• If the solver mixes two similar sizes, then pick either small size. If it takes a size under 5%, ignore it and follow the highest-frequency action.
• If the opponent is a calling station, then bet more value hands at bigger sizes and drop small-bet protection. If they are unknown or a good player, stay close to the solver sizing.

• Believing a big bet means a value-heavy range. The tell: you size up and bluff less, when a bigger bet actually supports more bluffs.
• Picking one action from a mixed spot and playing it every time. The tell: you always bluff or always give up the same hand type in a spot the solver splits roughly 40/60.
• Obsessing over minor sizes. The tell: you try to replicate a 1.47% bet size or treat 10 and 18 as different plays instead of one small bet.
• Carrying an exploitative size or frequency up a stake level. The tell: always betting small on Ace-high flops worked at $1 MTTs but fails at $5, where players bluff catch too much.
• Trusting a solve built on weak assumptions. The tell: your sizing 'matches the solver' but you guessed the ranges or bet sizes you entered, so the output is flawed or useless.

• ▸Board and position: note the flop and who is in position, and whether it is dry or wet.
• ▸Opponent type: GTO regular, unknown, or calling station/fish, which decides solver-style or exploitative sizing.
• ▸Primary objective: value extraction, equity denial, semi-bluff, or protect check range.
• ▸Candidate size (% of pot): write it out, e.g. $25 into $100.
• ▸Break-even for the caller: risk divided by (risk + pot + bet), e.g. 17% for $25 into $100, 33% for $100 into $100.
• ▸Target bluff share of your betting range: the same percentage as the break-even.
• ▸Value and bluff counts: list your value hands and bluff hands, then check the ratio against the target.
• ▸Hands that check: list strong hands kept as bluff catchers or to protect the check range.
• ▸Mix plan: write the frequency for each bluff candidate and which hands fill it (e.g. suited draws bet about half).

1. 1Define the spot first: stack depth, pot size, board, and the full range each player brings to the flop. Frequency is a property of a range in a spot, not of one hand. The source says to analyze 'how we would play every hand in the same situation'.
2. 2Read the solver grid for the aggregate bet share, then check each hand class. In the source's PIOSolver grid, AKs bets all the time, JJ mostly checks, and KK mostly checks but still bets a small share.
3. 3Filter noise before you act. Ignore any line the solver takes under 5% (the 1.47% bet of 66 is the source's example). Treat two similar sizes taken in similar measure (10 or 18) as one 'small bet' action. Focus on the highest-frequency actions.
4. 4Explain why the frequency is high or low. Compare range advantage with nutted advantage. When UTG had both, it bet 100%. When UTG kept the range advantage but had few nutted hands (only top set and top two pair), it bet 63%, almost all at 25% pot.
5. 5Assign hands to roles inside the betting share. The source's UTG example: bigger Ax bets for value; medium Ax checks as a bluff catcher; AA mixes because it doesn't need protection; A3s bets more because it blocks less of the calling range; 44 and 55 mostly bet to deny equity and because they have gutshots; KK-99 mostly check as strong bluff catchers.
6. 6Tie frequency to bluff-to-value. A pot-sized bet needs about 50% bluffs, which is 1 bluff per 1 value bet, and the opponent breaks even at 33% (per the source). A $25 bet into $100 supports about 17% bluffs. Check that your bluff share matches the size you chose.
7. 7Execute mixes as mixes. If the solver says bet a bluff 40% and check 60%, do not choose 'always bluff' or 'always give up'. Use a randomizer (e.g. the second hand on a clock) to hit the frequency.
8. 8Re-check the inputs. Betting frequency is only as good as the ranges and bet sizes you entered, so a wrong assumption yields a wrong frequency.

The source compares two UTG-vs-Big Blind flop spots. In the first, UTG has range advantage and nutted advantage and bets 100% of the time, with some large bets. In the second, UTG still has the range advantage but few nutted hands: only top set and top two pair. The Big Blind holds middle and bottom set, A3, A2s, 32s for two pair, 45 for a flopped wheel, and combo draws like 5♥6♥ and A♥4♥. UTG's betting frequency drops to 63%, and every bet is 25% of pot. Within that 63%: bigger Ax bets for value, medium Ax checks as bluff catchers, AA mixes, A3s bets more because it blocks less of the calling range, and 44/55 bet mostly to deny equity and because they have gutshots. KK-99 mostly check because only Ax or better calls them, which makes them strong bluff catchers. Betting 100% here would run UTG into big hands and check/raise bluffs more than it wants. The small size lets UTG fold to a raise and keeps in more hands it beats.

• If you hold both range advantage and nutted advantage, then bet at or near 100% and let large sizes into the mix; the opponent can only bluff catch.
• If you hold the range advantage but the opponent has more nutted hands or combo draws, then cut the frequency (the source's drop to 63%) and shrink the size, since a smaller bet lets you fold to a raise.
• If a hand is a strong bluff catcher that only better hands call (KK-99 in the example), then mostly check; if a hand needs no protection (AA), then mix.
• If the solver's bluff-or-check split is, say, 40/60, then play that split; never turn 'either is fine' into 'always one'. Always bluffing over-bluffs and always checking under-bluffs.
• If a solver action is under 5%, or two sizes are near-equal, then drop the rare line and merge the sizes into one 'small bet' action.

• Betting only certain hand types (all value, or all draws). The tell: your bet range has no bluffs or no strong hands, so the opponent folds easily or raises you light.
• Treating a mix as a free choice. The tell: you say 'bluff or give up, both are fine' and then do the same thing every time.
• Copying a high frequency from a spot with nutted advantage into a spot without it. The tell: you get check/raised often and face hard turn decisions after calls from very strong hands.
• Chasing minutiae. The tell: you try to replicate a 1.47% line or distinguish 10 from 18 instead of following the dominant actions.
• Using a solver output built on bad inputs, or exploiting at one stake level and carrying it up. The tell: the ranges or sizes you typed in don't match real opponents; or the always-c-bet strategy that worked on Ace-high flops against over-folders at $1 MTTs fails against bluff catchers at $5 MTTs.

• ▸Spot: positions, stack depth, pot size, board.
• ▸Range advantage (me/them/even): who has more equity overall.
• ▸Nutted advantage (me/them/even): count the two-pair-or-better combos each side holds.
• ▸Overall bet frequency: aggregate % of my range that bets.
• ▸Dominant size(s): after dropping lines under 5% and merging similar sizes.
• ▸Value hands that bet: hand classes and their frequencies.
• ▸Bluff/semi-bluff hands that bet: hand classes, and whether they block the calling range or have equity.
• ▸Check hands: bluff catchers and give-ups, with frequencies.
• ▸Bluff share vs size target: my bluff % compared with the break-even for this size (e.g. about 50% bluffs at pot, about 17% at quarter pot).

1. 1Fix the river bet size first. The ratio is a consequence of sizing, so you cannot choose a ratio independently of the bet. Write the bet as a fraction of the pot: pot = 1, bet = B.
2. 2Compute bluffs per value combo as B ÷ (1 + B). This is arithmetic from the indifference condition, not a quote from the book. The bluff-catcher wins 1 + B when the bet is a bluff and loses B when it is value, so indifference requires bluffs × (1 + B) = value × B. Examples: half-pot gives 1 bluff per 3 value combos; pot-size gives 1 per 2; 3x pot gives 3 per 4.
3. 3Count your value combos first, because your value bets drive your actions (the book's Chapter 3 theme). Value is the anchor and bluffs are sized to it, never the reverse.
4. 4Multiply value combos by the per-value ratio to get your bluff budget. If you have 12 value combos and bet 3x pot, the budget is 12 × 3/4 = 9 bluff combos.
5. 5Choose which hands fill the budget. Use your worst showdown-less hands, and let blockers decide between otherwise similar candidates. The book names blockers as part of deciding which hands to act with.
6. 6If candidates exceed the budget, mix; don't bluff them all. The book's example is a solver telling you to bet 40% as a bluff and give up 60%. Always bluffing that hand over-bluffs, and always giving up under-bluffs. Both diverge from GTO.
7. 7Cross-check against the opponent's required defence. At 3x pot the bettor risks 3 to win 1, so a caller must defend 25% (1 ÷ (1 + 3)). If the opponent folds more than 75%, your bluffs are printing money. If they defend more, bluffs lose.
8. 8Decide whether you are in an exploit spot or a balance spot. Against unknown or strong opponents, hold the balanced ratio. Against a known calling station, cut bluffs and widen value.

Dara O'Kearney holds A8o on an 8-3-2-6-Q board at EPT Berlin, and Randy 'Nanonoko' Lew bets 3x pot on the river after leading small on the flop and turn. The bet is pot = 1, bet = 3, so a bluff risks 3 to win 1. Dara's first-principles check: if he folds four-fifths of the time, Nano wins 1 unit four times and loses 3 once, a net profit from bluffing. To stop that, Dara must call 25% of the time, because 3 ÷ (3 + 1) = 75% is the fold rate where a bluff breaks even. Flip the viewpoint to Nano's range. Applying the indifference arithmetic, a balanced 3x-pot range holds 3 bluffs for every 4 value combos (3/7 bluffs, 4/7 value). With a hypothetical 12 value combos, he needs 9 bluff combos, and a pair of eights is a bluff-catcher that wins against those bluffs and loses to the value. The point is that the ratio set by his sizing is what makes Dara's call neither clearly right nor clearly wrong. Dara's takeaway from the hand was that always calling and always folding are both exploitable, so he must call about a quarter of the time and use blockers to choose which hands. The top players he asked split on 'Nano is full of it' versus 'it's three times the pot', which shows that reads, not the ratio, were driving their answers.

• If you bet bigger, then add more bluffs per value combo; a bigger bet needs a higher bluff share (3x pot: 3 per 4; pot-size: 1 per 2; half-pot: 1 per 3).
• If you have more bluff candidates than your budget allows, then bet only a fraction of them and check the rest; never promote all of them to bets.
• If the opponent is a calling station, then bluff less and value bet thinner and bigger; don't protect a small-bet range by betting the nuts small.
• If the opponent is unknown or strong, then keep the balanced ratio, since GTO is the starting point against both.
• If two bluff candidates are otherwise equal, then prefer the one whose blockers make the opponent's calling hands less likely.

• Sizing up without adding bluffs. The tell: you shove overbets with a value-heavy range and good opponents fold every bluff-catcher you wanted called.
• Treating 'bet or give up' as a free choice. Always bluffing or always giving up a mixed hand misses the frequency. The tell: your river bluffs from one hand class are 0% or 100% over a sample.
• Counting bluffs first and sizing value to match, so the budget grows from loose bluff candidates. The tell: you have more bluffs than value on a big bet.
• Applying a balanced ratio against an exploitable opponent. The tell: you bluff a calling station who calls everything and lose money.
• Ignoring blockers when picking bluffs. The tell: your bluffs hold cards that are not relevant to the calling range, so they fold out few hands.

• ▸Pot size: record the pot before your bet (set = 1).
• ▸Bet size as fraction of pot (B): the size you intend to use.
• ▸Bluffs per value combo = B ÷ (1 + B): compute this once from B.
• ▸Value combos in range: count the hands you bet for value on this board.
• ▸Bluff budget = value combos × bluffs per value: the maximum bluff combos.
• ▸Bluff candidates available: list your worst hands, with blocker notes beside each.
• ▸Frequency per candidate: bet % vs check %, so total bluff combos equal the budget.
• ▸Opponent defence needed = 1 ÷ (1 + B): the fold-rate check against their actual calling.
• ▸Opponent type (unknown / strong / calling station): decides balanced versus exploit adjustment.

1. 1Define EV as the chips or big blinds a specific action earns, then judge every action by its EV across the whole range. A solver grid shows what each hand does; the aim is the range-level reason, not a verdict on one hand.
2. 2Read the frequencies as an EV signal. When one action is clearly the most profitable, the solver takes it nearly 100% of the time. When it mixes, the options have similar EV. A hand that mixes is near a point of indifference.
3. 3Discard any action under about 5% frequency (the book's example is a 66bb bet at 1.47%). Treat two similar sizes taken in similar measure, such as 10bb and 18bb, as one 'small bet' option. Study only the highest-frequency action types.
4. 4For each action, list which hands take it and which do not. Example: JJ mostly checks, AKo mostly bets, AKs bets always, mixing 36bb and 18bb. Ask why those hands and not others, rather than whether your hand matched.
5. 5Check suits and blockers. The same hand can take different lines by suit (AKo may check back with a spade and bet without one). When EV is close, blockers decide: a card that removes the opponent's value hands raises the EV of calling, and a card that removes his bluffs lowers it.
6. 6Compute EV from combinations and pot odds. Count the opponent's value and bluff combos with your cards removed, then compare the equity you need (from the bet size) with the equity you have.
7. 7Study the opponent's grid as well as yours. You learn in-position and out-of-position strategy from the same solve. Confirm that the ranges and bet sizes you fed in are realistic, because the EV is only as good as those inputs.
8. 8Replicate mixing frequencies across the whole range. If a bluff is 40% bet and 60% check at equal EV, do not always bluff or always give up. Either one shifts you off the range-level optimum.

The book's dice-style toy game isolates EV at a point of indifference. Player A holds AA, 33 or 22 and Player B holds KK, QQ or JJ, with one pot-sized bet on a meaningless river board (8♠ 9♥ 4♠ 8♥ 8♦). The solver has A shove AA 100% of the time and 33 and 22 each ¼ of the time. That gives two value combos per bluff, so B is laid 2-1 and calls 50% of the time. With KK, QQ and JJ, B calls each 50% of the time. The EV of calling is identical across the three because each is equally behind AA and equally ahead of 33 and 22. Swap the three KK combos for A9o played half the time (six combos) and A's strategy does not change. B's strategy does: B always calls with A9o and only ¼ of the time with QQ or JJ. B still calls 50% overall. A9o holds an Ace, so A has three AA combos against it instead of six, and calling with it earns more EV. The lesson: the EV of an action depends on the whole range and on blockers, not on raw hand strength.

• If one action is clearly the most profitable, expect the solver to take it nearly 100% of the time, so take it too.
• If the solver mixes between actions, treat their EVs as close and match the frequency over your range. Do not pick one option every time.
• If an action is under about 5% frequency, ignore it. If two bet sizes appear in similar measure, either small size is fine.
• If EV is close, let blockers decide: call more with hands that block the opponent's value hands, and bluff with hands that block his calling hands. In the toy game, A9o calls more because it blocks AA.
• If your opponent's range is narrow and the spot is a 3-bet pot or river, run the combo count. A blocker can move equity by 25 points or more (JJ 25%, K2o 50%, an A♣ or Q♣ 0%).

• Line-checking: entering the hand you played and asking whether the solver agreed. The tell: you accept a 1.2% line as proof you were right.
• Studying only your own hand. The tell: you can say what your hand did but not which other hands take the same action.
• Reading mixed actions as free choice. The tell: you always bluff or always give up with a hand the solver mixes, which over- or under-bluffs.
• Treating junk inputs as truth. The tell: you trust a solve whose ranges and bet sizes you never checked.
• Ignoring blockers and suits when EV is close. The tell: you fold or call purely on hand strength, such as folding K2o to a bluff-catching spot where it is break even while calling with a hand that blocks your outs.

1. 1Define the unit before you track anything: big blinds per 100 hands (or ROI for tournaments), measured over the full sample and never over a session. The source frames GTO as profitable 'as an overall strategy', not in any single hand, and win rate is the same kind of aggregate number.
2. 2Split your database by opponent softness before reading the number. The source says an unexploitable baseline earns money 'whenever your opponent plays in an exploitable style', and GTO is 'never the most profitable' way to play against a weak player. One blended win rate hides whether you earn from soft games, tough games, or both.
3. 3Record table count next to every session and report win rate per table count. The source's point is that a pro on 12 tables has a much worse win rate per table than on six. Judge whether the extra volume is worth the per-table loss instead of reading one blended figure.
4. 4Track exploitative deviations as a separate bucket. When you target a fish with wider 3-bets or thinner value bets, tag those hands and compare their results with your baseline hands. The source warns that tough regulars at the table can counter-exploit you, for example by 4-betting wide against a wide 3-bet, so check whether the deviation pays net of that.
5. 5Treat a solver as a leak finder, not a score. Run solves with the ranges and sizings you believe your real opponents use, because a solve is only as good as its inputs. Use it to plug your biggest leaks first, since fixing leaks is the route to a higher win rate. Ignore any line the solver takes less than 5% of the time.
6. 6Judge your line at the range level. Ask what every hand in your range does in the spot, not whether the solver matched your one hand. The source calls 'did the solver agree with me' a close-minded method, and a line taken 1.2% of the time does not mean you played correctly.
7. 7When a fish sits down, deviate on purpose and record it. The source says all the best players diverge from GTO against a particularly fishy opponent. Return to your baseline when the fish leaves or when a strong regular is also in the pot, because the source says exploiting works best when you get the pot heads-up with the bad player.
8. 8Review the number in a fixed cadence over large samples only. A GTO baseline reduces what you lose to counter-exploitation but can cost value at low stakes and slow early progress. Judge it by whether it proves profitable and holds up as you move stakes.

The source's Rock/Paper/Scissors drill shows how a long-run win rate trades off against exposure. Player 1 plays the balanced 1/3 mix against a Player 2 who plays Rock 36 times, Paper 18 and Scissors 18 out of 72 games. Player 1 breaks even overall (Paper +6, Scissors -6, Rock 0), but variance rises. Player 1 then exploits by playing Paper every time. Paper wins 36 games against Rock, loses 18 against Scissors and ties 18, so Player 1 is up 18 over 72 games. The catch is that Player 2 will notice and shift to Scissors, so Player 1 must tone it down. The source puts a half-Paper, quarter-each mix at +7.5. Recomputing from its stated frequencies gives +4.5, so check the arithmetic if you reuse the figure. Either way the gain is far below +18. The lesson for your database is that the more you deviate, the higher the win rate against a fixed opponent and the larger the counter-exploit risk. Measure both.

• If the opponent has a clear leak and you are likely to get the pot heads-up with them, then deviate and tag the hands as exploitative. If a tough regular is also in the hand, then return to the baseline.
• If you are adding tables, then judge the change by win rate per table, because the source says per-table win rate falls as tables rise. Do not judge it by a single blended number.
• If a solver line appears less than 5% of the time, then ignore it. If two similar sizings appear in similar measure, then treat any small sizing as acceptable.
• If your win rate is flat or slowly rising at low stakes, then weigh the lost value from playing GTO fundamentals against the benefit. The source says a proven profitable GTO-based game can move to any stake.
• If you want to improve the number, then fix your largest leak first. Study outlier hands after that.

• Reading a short sample as your win rate. The tell is that you change your strategy after a stretch of results instead of after a large-sample comparison.
• Treating GTO as the most profitable play against everyone. The tell is that you never deviate against obvious fish and your results against soft games look no better than against tough ones.
• Over-exploiting, as Player 1 does by playing Paper every time. The tell is that early results are strong, then regulars start 4-betting or raising you and the gains vanish.
• Solving with premade ranges and sizings instead of your opponents' actual tendencies. The tell is that solver conclusions never match how your real opponents behave.
• Checking only whether the solver played your one hand the same way. The tell is that you can name the solver's action for your hand but not for the rest of your range.

• ▸Sample window: dates and number of hands (or tournaments), so the number is read over a large sample.
• ▸Unit and overall result: bb/100 or ROI for the whole window.
• ▸Game softness: label each session soft or tough and record the result for each group.
• ▸Table count: tables played per session, with win rate per table count.
• ▸Baseline (GTO-style) hands: result for hands played without opponent-specific deviation.
• ▸Exploitative hands: result for tagged deviations against specific leaks, and whether the pot was heads-up with the weak player.
• ▸Counter-exploitation notes: any regular who 4-bet, squeezed or raised you in response, and which line triggered it.
• ▸Solver check: spot reviewed, ranges and sizings you input, and the leak identified (ignore lines under 5%).
• ▸Next action: the one leak to fix, or the one deviation to keep or drop, before the next review.

1. 1Name the leak you are guarding against. Unexploitable means no leak like bluffing too much or too little, or calling too much or too little. Write down which of those four your line in this spot could drift into.
2. 2State your assumptions before trusting any output. A solver result is only as good as the ranges you believe each player has and the bet sizes you believe each would use. If you can't say them, you don't have a baseline yet.
3. 3Sort the spot as 'clear' or 'needs a split'. Most hands have a clear straightforward play, so only a few decisions per session need mixing. These are mostly the outlier hands where the solver gives several actions.
4. 4When you split, keep the frequency, not just the option list. If the solver says bet 40% as a bluff and check 60%, 'bluff or give up are both fine' is wrong. Always bluffing over-bluffs and always giving up under-bluffs, and either one is a deviation.
5. 5Pick the split with a blocker first. On J♥9♥4♠ with pocket Kings, K♥K♠ blocks the flush draw, so you need less protection and can lean toward the small bet. K♦K♠ blocks nothing, so it leans toward the bigger bet.
6. 6If blockers don't decide it, randomise. Assign number ranges to your frequencies (60% big, 30% small, 10% check = 1-60, 61-90, 91-100) and use a random number generator. Live, use the clock's seconds hand: 1-36 big bet, 37-54 small bet, 55-60 check.
7. 7Decide whether to stay unexploitable or deviate. Against unknown or strong players, play as close to GTO as you can. Against a clearly weak player or a calling station, counter-exploit, accepting that you are open to counter-exploitation.
8. 8Stress-test the line. Ask whether the opponent would lose money by widening or tightening their response. If they would, you are near equilibrium. If one of their adjustments makes money, you have found your leak.

Dara built push/fold ranges for SNGs using an equity calculator and a spreadsheet. The regulars noticed he was shoving wider, so they widened their calling ranges. He tightened his shoving range against those calls, so they tightened up against him. He widened again, and after a few more rounds he saw the process settling at an equilibrium. At that point, if he shoved wider he would lose money, and if they called wider they would lose money, even though each knew the other's ranges. That is unexploitability: neither side gains by deviating. He later leaned on the same principle at EPTs against players he couldn't read: 'It doesn't matter what they do, if you are unexploitable they cannot beat you.' The tell that you have reached it is that every adjustment your opponent can make costs them money.

• If you have no read, no stats, or the opponent is a strong player, then play as close to GTO as possible.
• If the opponent has a clear leak, such as a calling station, then deviate and exploit, knowing you are open to counter-exploitation.
• If a solver mixes an action (for example 40% bluff, 60% check), then reproduce the frequency across hands rather than choosing one action every time.
• If blockers differentiate two hands in the same spot (K♥K♠ vs K♦K♠), then use them to decide which hand takes which bet size before reaching for a randomiser.
• If a hand has one clearly best play, then play it straightforwardly and save randomising for the few spots that need a split.

• Reading a mixed strategy as 'either is fine'. You always bluff or always give up. The tell is that your bluff frequency in a spot is near 100% or 0% instead of the solver's mix.
• Treating a solver as the definitive answer. You line-check a hand and stop without questioning the ranges and sizes you input. The tell is that you can't say what assumptions produced the output.
• Over-exploiting and getting countered. After thin value betting, a good regular spots it and raises you off hands that were profitable when played passively. The tell is raises against your habitual line.
• Playing pure GTO against a fish. You make a small river bet with the nuts to protect your small-bet range against a calling station, which burns money. The tell is that you aren't extracting from an opponent who clearly calls too much.
• Believing unexploitable means maximum profit or breakeven. You expect GTO to win the most in every hand, or to just stalemate. The tell is that you refuse to deviate against weak players, or you assume you can't profit from others' leaks.

• ▸Spot (hand, board, position, action so far): describe the decision in one line.
• ▸Opponent type: unknown, strong, or clearly exploitable. This decides GTO baseline vs deviation.
• ▸Assumed ranges and bet sizes: write the ranges and sizes you believe each player uses.
• ▸Leak risk: which of bluffing too much/too little or calling too much/too little does this line risk?
• ▸Clear or split?: mark whether one action is clearly best or the spot needs a mixed strategy.
• ▸Target frequencies: write the split, such as 60% big, 30% small, 10% check.
• ▸Blocker tiebreak: list which holdings block key draws and which action each favours.
• ▸Randomiser assignment: map each action to numbers 1-100 or to seconds on the clock.
• ▸Deviation decision and counter-exploit risk: state whether you exploit or stay balanced, and what the opponent could do back.

1. 1Define the baseline as a leak check, not a script. GTO means a strategy that cannot be exploited: no bluffing too much or too little, no calling too much or too little. For each spot, ask whether your frequencies could be punished by an opponent who adjusts.
2. 2Make GTO your default against unknown players and very good players. When you have no reads and no HUD stats, the source says to play as close to GTO as possible. Play exploitatively only once an opponent shows an observable leak.
3. 3When you study a hand in a solver, enter the ranges and bet sizes you believe your real opponents use, not premade GTO ranges. Include their donk leads and their reraise sizes. Online, the default sizes are usually a small bet, about 2/3 pot, and pot. Premade inputs only describe perfect opponents, which you do not face.
4. 4Budget for solve time. Deeper stacks, wider ranges and more bet sizes all cost more processing. A Blind vs Blind 100bb solve with wide ranges can take a day to give a usable answer.
5. 5Read the whole output, not just the action. Check the EV and equity of both ranges and of individual hands, plus the best and worst turn cards. Do not treat the solver as the definitive right answer. It is only as good as the assumptions you entered.
6. 6Group hands by how they play: small pairs bet big, suited connectors check/call, and so on. Then isolate the outliers that break from their group, such as JJ betting big while AA bets small on low flops, and ask why they diverge. Use the first pass of solver work to plug your biggest leaks. After that, the outliers teach you the most.
7. 7When you deviate to exploit, name the leak you are targeting and accept the cost: you are now open to counter-exploitation. If the opponent adjusts, as regulars do when they notice you widening or value betting thin, move back toward the baseline instead of doubling down.
8. 8Use the baseline as a mental anchor. If you called 40% of the time on the river because that was the balanced frequency, you can accept the outcome of a single hand. Take hands that bother you back to the solver and either confirm the play or learn something.

Dara O'Kearney built a push/fold spreadsheet as an SNG grinder. It worked until regulars noticed he was shoving wider and widened their calling ranges. He tightened his shoving range against their new calls. They tightened their calls, so he widened his shoves again. After a few rounds he saw the pattern: the two sides were converging on an equilibrium where neither would deviate despite knowing the other's ranges. If he shoved wider he lost money, and if they called wider they lost money. That is the GTO idea in miniature. Each exploit invited a counter-exploit until the strategies settled where no deviation paid. The same logic later helped him at EPTs against stronger players he could not read. His takeaway was that if you are unexploitable, it does not matter what they do, because they cannot beat you.

• If you face an unknown player, a very good player, or a HUD-free table with many tables open, then play the GTO baseline, because you have no reliable read to exploit.
• If an opponent shows a clear, repeatable leak, such as overfolding on Ace-high flops, then deviate to exploit it, for example by betting Ace-high flops always and small, and accept the exposure to counter-exploitation.
• If you move up in stakes, then do not carry the old exploit with you. Overfolding at $1 MTTs can become over-bluffcatching at $5 MTTs, so rebuild from the baseline.
• If a solver output surprises you, then ask why that hand plays differently from its group before copying the line. Check that the ranges and sizes you entered match what real opponents do.
• If opponents start adjusting to your exploit, then step back toward the baseline until you have new information.

• Believing GTO is the most profitable way to play. The tell is that you play balanced against an obvious fish. GTO is never the maximum-EV play against an exploitable opponent. The best players diverge from it when a very fishy opponent sits down.
• Treating the solver as an answer key. The tell is that you line-check a hand and stop without asking why. Output is only as good as your inputs, and a bad player running a solver can come out worse than before.
• Solving with premade GTO ranges and sizes. The tell is that your solves look clean but never match what your opponents actually do. Input the ranges and sizes you believe your real opponents use.
• Dismissing GTO at small stakes. The tell is that you build an exploit-only strategy that collapses when you change levels. It also leaves you tilting over results because you cannot tell whether a play was right.
• Exploiting without noticing the counter-adjustment. The tell is that a thin value-betting or wide-shoving line that was working suddenly gets raised or called more, forcing you to fold hands that would have been profitable played more passively.

• ▸Spot: Position, stack depth and street, e.g. BvB 100bb flop.
• ▸Opponent knowledge: Unknown, very good, or a read-based type such as a calling station. Note whether you have any stats.
• ▸Observed leak: The specific, repeatable error, such as overfolding Ace-high flops. Write 'none' if you cannot name one.
• ▸Baseline play: What an unexploitable strategy does here, including mix frequencies such as 'call 40% on river'.
• ▸Solver inputs used: Ranges, bet sizes, donk leads and reraise sizes you entered. They must reflect your real opponents.
• ▸Outlier hands: Hands that diverge from their group's line, and your hypothesis for why.
• ▸Exploit chosen: The deviation, such as always bet small on Ace-high flops, or 'none, play baseline'.
• ▸Counter-exploit risk: How a good regular could punish this deviation and what the sign of adjustment would be.
• ▸Review result: Did the opponent adjust? Return to baseline, keep the exploit, or re-solve with updated inputs.

1. 1Reclassify the flop as static or dynamic, not wet or dry: ask whether most turn/river cards will change who holds range advantage. If they won't, it's static; if many cards flip the equity distribution, it's dynamic.
2. 2Test with the book's paired example: on A♠9♠6♠, notice that despite three to a flush it is hard for later cards to reshape relative strength — the top of both ranges is largely set. On 9♣6♦4♠, count how many overcards, straight cards and pairing cards would swing equity — this is the dynamic one.
3. 3Map how texture caps or uncaps each player's range. On 9♦7♦8♥ a polar range with only overpairs becomes capped because it cannot make two pair, set or straight; a capped preflop range can turn uncapped on the same connected flop.
4. 4Count your value bets before choosing sizing: texture determines how many strong hands each range holds. More coordinated/connected texture means more nutted combos exist, which supports bigger bets; a paired dry board narrows value and favours small bluff-heavy sizing.
5. 5Adjust bet size to the equity spread the texture creates: on static boards where later cards rarely change things you can bet a wide range small; on dynamic boards where turns swing equity you protect and deny with larger sizing.
6. 6Check whether the texture lets you keep balance on later streets — reserve some strong hands and some bluffs for scary turn/river cards (e.g. the flush-completing turn) so your range on future textures isn't exploitable.

Take the flush-draw scenario from the passages. You flop the nut flush draw with Ax suited — a classic semi-bluff spot where betting is instantly profitable. Now consider what happens when you check back and the third card of that suit hits the turn, changing the texture from a two-flush draw board to a completed-flush board. Against a thinking opponent who has shared table time with you, that turn texture means you 'never have the nuts' if you always bet your draws on the flop, so they can check/raise your turn bets and fold out your value. The fix is a texture-aware balance: some of the time you bet the nut flush draw on the flop, some of the time you check it back, so that when the third suit card arrives you still credibly represent the flush. This preserves a protected turn betting range so you can bluff those flush-completing turns when you have nothing.

• If most turn and river cards leave the relative strength of both ranges unchanged, then treat the board as static and bet wider with smaller sizings.
• If many cards can hand range advantage to the other player, then treat the board as dynamic and size up to deny equity and protect made hands.
• If your own strong-hand count is low on this texture (e.g. a paired dry board like 2♥2♣7♦), then favour a small bluff sizing rather than a large value sizing.
• If betting all your strong hands would leave only medium and weak holdings in your checking/calling range, then don't — you cap yourself and become attackable by overbets on later streets.
• If a scary card (a flush-completing or straightening card) is likely, then reserve some nutted hands and some bluffs for that runout so your range on the new texture stays balanced.

• Equating dynamic with wet: labelling A♠9♠6♠ dynamic because it's three-flush when it's actually fairly static, and calling 9♣6♦4♠ dry when it's the dynamic board. Tell: you size purely off number of draws, not off how much later cards change equity.
• Always betting the nut flush draw on the flop. Tell: on the flush-completing turn a regular check/raises you and you can never continue because you 'never have the nuts'.
• Capping your flop checking/calling range by betting and raising every strong hand. Tell: your turn range is all medium/weak and a competent opponent overbets you off it.
• Ignoring texture when picking bet size — using one sizing everywhere. Tell: your big bets get folded on dry boards and your small bets get overcalled on coordinated boards.
• Failing to protect medium made hands on dynamic textures. Tell: you check a hand like 99 on a coordinated board, an overcard lands on the turn, and you've handed the opponent equity you could have denied.

• ▸Flop cards: write the three community cards
• ▸Static or dynamic: will most turn/river cards change range advantage? (yes = dynamic)
• ▸Coordination/pairing/high-card notes: list what the texture supports (straights, flushes, pairs)
• ▸Your value-hand count: how many nutted combos your range holds here
• ▸Is your range capped or uncapped on this texture, and why
• ▸Scary future cards: which turns/rivers swing equity most
• ▸Chosen bet size and why (small=wide/static, large=protect/dynamic)
• ▸Balance reserve: which strong hands and bluffs you hold back for the scary runout

1. 1Define both ranges before you look at your cards. Write down the opener's range and the defender's range for the exact spot (position, stack depth, format). The source example is UTG vs Big Blind in a 40BB effective MTT pot, with both ranges taken from Range Trainer Pro.
2. 2Read raw equity as a showdown claim. The test is how often each range wins if both players show down with their entire range on every runout, as in a check-down or when one player is already all-in. Ask 'who wins more often if nobody can fold?', not 'who hits more often?'
3. 3Sort each range into buckets on the flop: overpairs, top pair (and its kicker quality), sets (top, middle, bottom), draws, and complete misses. Count the proportion of each range in each bucket, not only whether the hand type exists in both ranges.
4. 4Compare proportions where both ranges contain the same hand type. On Q♦6♥2♥ both players hold Qx, but Qx is a bigger share of UTG's range, and the Big Blind's Qx has kicker problems. Overlap in hand types does not mean equal strength.
5. 5Tally the top end and the miss rate. UTG holds overpairs plus top and middle set. The Big Blind holds middle and bottom set and more draws, but mostly misses the flop entirely. Note which side has the stronger top end and which side mostly misses.
6. 6Put a number on it and name the owner. UTG's range has 63% equity and the Big Blind's has 37%, so UTG has the range advantage. Any edge counts, even 51%. A bigger gap means a bigger strategic shift, so size the gap before choosing a strategy.
7. 7Play the range, not the hand. Your specific holding can be bad on a board that is very good for your range. With UTG-opened JJ on AK2 rainbow, the gut says check back, but the right strategy may be to continuation bet, because the flop is terrible for the hand and very good for the range.
8. 8Check that you are not capping yourself. If you bet and raise all your strongest hands on the flop, your checking and calling range holds only medium and weak hands and gets attacked by overbets on later streets. Keep strong hands in the ranges you check and call with.

UTG opens in a 40BB effective MTT pot and the Big Blind defends. The flop is Q♦6♥2♥. Both ranges contain Qx, but Qx is a larger proportion of UTG's range, and the Big Blind's Qx suffers from kicker problems. UTG also has overpairs and top and middle set. The Big Blind has middle and bottom set and more draws, but for the most part wildly misses this flop. Range Trainer Pro puts the split at 63%/37% for UTG, meaning UTG wins 63% of the time if both ranges always get to showdown on every runout. UTG has the range advantage, so the Big Blind should expect to play from the weaker side. The same logic explains why a UTG opener holding JJ on AK2 rainbow should consider continuation betting despite holding a hand that dislikes the board.

• If the board is bad for your specific hand but good for your overall range, then choose the action for the whole range (the source suggests a continuation bet with JJ on AK2 rainbow) rather than the one your gut suggests.
• If both ranges contain the same hand type (such as Qx), then compare how large a share of each range it is and the kicker quality before calling it a wash.
• If your edge is only a few points (51% still counts), then expect a modest strategic shift. If it is large (63/37), then expect a more profound one.
• If your opponent has capped their checking and calling range (for example, they raise all top pair or better on 9♦7♦8♥) and a brick turn like a 2 arrives, then overbet to put their whole range under pressure.
• If you hold the range advantage but are tempted to bet and raise all your strongest hands, then keep some strong hands in your checking and calling range so it is not capped.

• Judging by your own hand (the curse of knowledge). The tell is checking back JJ on AK2 simply because the hand looks bad.
• Counting hand types rather than proportions. The tell is saying 'we both have Qx' and calling the flop even when Qx is a bigger share of one range and carries kicker problems on the other side.
• Treating range advantage as only the nuts or the most sets. The Big Blind had more draws and some sets and still had only 37% equity, because most of its range missed. The tell is pointing to a few strong combos while ignoring how much of the range misses.
• Thinking the edge must be large to matter. The tell is dismissing a 51% edge as 'basically even', when the source says any such edge counts and shapes both players' betting.
• Capping your own range by betting and raising all your strongest hands on the flop. The tell is a checking range of only medium and weak hands, which invites a turn overbet after a brick.

• ▸Spot: format, positions, effective stack (e.g. UTG vs BB, 40BB MTT).
• ▸Flop: the exact board texture.
• ▸Opener range and defender range: paste or note the source (e.g. Range Trainer Pro) for each.
• ▸Shared hand types: list overlapping hands (e.g. Qx) and which range has the larger proportion and the better kickers.
• ▸Top-end hands: overpairs, top pair, and sets (top, middle, bottom) for each side.
• ▸Draws and complete misses: estimate each side's draw share and miss share.
• ▸Raw equity split: record the full-range equity figures (e.g. 63/37) from the solver or trainer.
• ▸Who has the range advantage, and by how much? Name the owner and size the gap (slight like 51%, or large).
• ▸My specific hand vs my range: note whether the board is bad for my hand but good for my range, and what range-level action that implies.
• ▸Cap check: are my strongest hands all in my betting range, leaving my check/call range medium and weak? Note any hands to keep back.

1. 1Separate the two questions before acting. First ask who has range advantage (higher overall equity). Then ask who has nutted advantage (higher proportion of very strong hands). The two can point in opposite directions.
2. 2Define 'nutted' by stack-to-pot ratio. Count hands you would be happy to stack off with. At shallow stacks two pair counts as nutted. At deeper stacks the bar rises.
3. 3List the nutted combos on the flop for both players: sets, two pair, straights, and combo draws with high equity. In the 6♣5♦4♥ example that means 87 and 32 for straights, plus sets, two pair and combo draws.
4. 4Compare the proportions, not the raw counts. Ask what share of each range is nutted. In A♦3♥2♥ UTG's only very strong hands are top set and top two pair, while the Big Blind holds middle and bottom two pair, 45 for the wheel and combo draws like 5♥6♥ and A♥4♥.
5. 5Set the betting frequency from the combined picture. Range advantage plus nutted advantage (Q♦6♥2♥ style) means bet nearly everything. Range advantage without nutted advantage means mix, and bet less. Nutted advantage for the opponent despite equal or lower equity means they can lead out.
6. 6Shrink the size when you lack the nuts. On A♦3♥2♥ UTG bets 63% of the time and always at 25% pot. A small bet leaves room to fold to a raise and keeps in hands you beat.
7. 7Rebuild your checking range. Keep strong hands (top set, KK–99 as bluff catchers) in the check range so the opponent cannot pile pressure on a range of only weak Ax and worse. Use the weakest pairs (77–44) as bets that deny equity.
8. 8If the opponent holds the nutted advantage, expect a lead and play passively. Call about as often as the solver does (80% in the example) and do not raise, even with a good hand like a set of sixes.

The flop is 6♣5♦4♥ in a 100BB cash game, with UTG opening and the Big Blind calling. Equity is a straight 50/50. UTG has more strong hands overall, including all the overpairs, but no nutted hands, and misses a lot with broadway high cards. The Big Blind has 87 (UTG has it only rarely) and 32 for flopped straights, plus sets, two pair, one pair and every draw and combo draw. For example 7♦4♦ and 6♦3♦ have over 69% equity against UTG's range, with one pair, an open-ended straight draw and a backdoor flush draw. Because of the gap in nutted hands, the Big Blind leads out 81.1% of the time, always small, and could practically lead 100%. UTG has to call 80% and fold the rest, with no raising, not even with a set of sixes, since it could face a better hand or a flipping combo draw. UTG usually has the best hand and the Big Blind usually misses, yet the Big Blind's ability to hold monsters, and UTG's inability to, drives the action.

• If you hold both range advantage and nutted advantage, then bet nearly all your hands (UTG bet 100% on Q♦6♥2♥), including big sizes at times, and expect the opponent to only bluff catch.
• If you hold range advantage but few nutted hands (A♦3♥2♥), then bet less often (63%), prefer small sizes (25% pot), and check strong bluff catchers like KK–99.
• If the opponent has more nutted hands than you, even with equal equity, then expect leads, call or fold, and do not raise with merely good hands.
• If your hand does not benefit from folds (AA on Q-high or Ax-low boards) or protects your check range, then mix it into your checking range so the range is not capped.
• If the opponent is a calling station rather than a thinking player, then raising can be fine, but against a thinking player it is a huge mistake.

• Treating range advantage as sufficient to bet 100%. The tell: you get check/raised and face big hands on turns after betting large into a range with more nutted hands.
• Using the wrong threshold for 'nutted'. The tell: you stack off with two pair at deep stacks, or undervalue it at shallow ones, because you ignored SPR.
• Betting every strong hand and leaving the check range weak. The tell: the opponent applies turn and river pressure to your capped checking range with Ax and worse.
• Raising a strong but non-nutted hand against a range with the nutted advantage (e.g. a set of sixes on 6♣5♦4♥). The tell: you run into better sets, straights or flipping combo draws.
• Judging the flop from your own hand rather than your range. The tell: you check JJ on AK2 rainbow out of gut feeling, when the flop is good for your range.

• ▸Board and stack depth: write the flop and effective stack in BB.
• ▸Nutted threshold: state which hands you would stack off with at this SPR (e.g. two pair or better).
• ▸My nutted hands: list the combos that qualify in your range and estimate their share of your range.
• ▸Opponent nutted hands: list the combos that qualify in their range and estimate their share.
• ▸Range advantage: estimate who has more equity, and by roughly what split.
• ▸Nutted advantage holder: me, opponent, or neither.
• ▸Planned frequency: bet or lead often, mix, or mostly check.
• ▸Sizing: small or big, and why (leeway to fold to a raise, hands I keep in).
• ▸Check-range protection: which strong hands I keep in my checking range so it is not capped.

1. 1Name the decision first. The source's blocker examples cover three kinds: choosing a bet size, choosing between actions, and choosing which hands call or bluff. Write down which one you face before you look at your cards.
2. 2Write the opponent's range for this spot. Blockers matter most when the range is narrow and the decision is close, so a wide, vague range is a warning that blockers are not your main lever yet.
3. 3List the strong combinations you care about: the draws you want to protect against, the top of a 3-betting range, or the nuts. Then check which of them your hole cards remove.
4. 4Compare your two (or more) versions of the same hand. In the source, K♥K♠ and K♦K♠ are strategically different on J♥9♥4♠ even though both are pocket Kings. Look for the suit or card that changes the opponent's combinations.
5. 5Translate the removal into an action. If your card removes the opponent's draw, you need less protection, so you can pick the smaller bet. If it removes none, the hand needs protection, so you can pick the bigger bet.
6. 6When you are bluffing or bluff-catching, use blockers to pick the specific hand. Bluffs and bluff catches should only break even long term, so the blocker is what separates the better candidate from the worse. For example, A♥6♥ bluffs the Q♠J♦2♠4♦8♠ river with an expectation of 0.6 big blinds.
7. 7Keep the effect in proportion. Blockers decide which hands take an action. Value from having the best hand is where the money is, so don't build a whole decision on one removed combination.
8. 8If the hand sits on the fence between two actions, use the blocker as the tiebreaker. If the spot still looks split, randomise (the source's example is a 60/30/10 split using number ranges or a clock's seconds hand) instead of forcing the blocker to settle it.

The source gives pocket Kings on a J♥9♥4♠ flop. You hold K♥K♠. The K♥ blocks the heart flush draw, so you are less worried about protecting your hand against a flush draw and might pick the small bet size. Now you hold K♦K♠. You have no heart, so the flush draw is fully live against you, the hand benefits more from protection, and you might bet bigger. Same two Kings, same board, but one removed card changes the size. The same logic shows up preflop: in a cash game you get 3-bet more often, so Ax hands go up a little in value because they block the top of a 3-betting range. In MTTs the antes make opening and defending more profitable, so the cash-game range carries a few more Ax hands and fewer speculative hands like T8s. In both cases the hole cards change what the opponent can hold, and that moves a decision at the margin.

• If your hole card removes the opponent's flush draw (K♥ on a heart-heavy board), then lean toward the smaller bet size, because you need less protection.
• If your version of the hand blocks none of the draws (K♦K♠ on J♥9♥4♠), then lean toward the bigger bet, because the hand benefits more from protection.
• If you must bluff or bluff-catch, then choose among the candidate hands by what they block, because a bluff or a bluff catch only breaks even and the blocker is the edge between candidates.
• If the ranges are wide or the decision is not close, then do not lean on blockers; they matter most when ranges are narrow and the spot is marginal.
• If a hand's action is a pure split in the solver (a check/bet mix, or one that changes by suit), then treat the blocker as a pattern to copy, not a reason to override the mix.

• Over-weighting the blocker in a wide-range spot. The tell: you justify a call or bluff with one removed combination while the opponent still has dozens of other strong hands.
• Treating blockers as the main source of profit. The source says you make money by having the best hand and getting value: A♠K♠ the nuts is worth 55 big blinds, while the bluff A♥6♥ is worth 0.6. The tell: you spend your study time on bluff candidates instead of value hands.
• Treating two versions of the same hand as identical. The tell: you bet K♥K♠ and K♦K♠ the same size on J♥9♥4♠ without checking which suit blocks the draw.
• Reasoning from one blocker and ignoring the opponent's range. The tell: you can name the card you hold but cannot say which strong combinations are left.
• Copying a solver output without understanding the pattern. The source says even elite players cannot replicate it exactly, and that actions under 5% frequency can be dismissed. The tell: you chase a rare, low-frequency mix as if it were a rule.

• ▸Decision type: bet size, bet vs check, call vs fold, or bluff selection. Write which one it is.
• ▸Board and street: write the exact cards.
• ▸Opponent range width: narrow, medium, or wide. If wide, mark blockers as a minor factor.
• ▸Strong combos that matter: list the draws, nuts, or 3-bet holdings you care about.
• ▸My hole cards: write the exact suits.
• ▸Combos removed: which of the strong combos does my hand remove?
• ▸Sibling hand comparison: how would a different suit combination of this hand (like K♦K♠ vs K♥K♠) change the answer?
• ▸Action it points to: the smaller or bigger bet, the bluff candidate, or the bluff catch.
• ▸Closeness check: is the decision close? If not, ignore the blocker and play the hand's value.
