Exploitative Adjustments

Lesson 26 · When to deviate from baseline GTO · 28 practice questions

Exploit leaks

A balanced strategy is built so that it cannot be exploited; it does not try to win the most against a player who is making a clear mistake. When you have a real read, you deviate — and the direction follows from the mistake. Against a player who folds too much, bluff more and bluff-catch less, because his bets are honest. Against a player who calls too much, stop bluffing and value bet wider and bigger. Against a player who bluffs too much, call down lighter and let him bet instead of betting yourself. Two conditions keep this honest: the read has to be real — several hands, not one showdown — and the deviation has to aim at that mistake and nothing else.

Example. River K♥7♦2♣5♠9♥, pot 16: your draw missed with Q♥J♣ and a nit checks to you. Queen-high cannot win at showdown, and this opponent folds everything except a strong king — bet. Same kind of hand against a calling station, 7♥6♦ on K♣8♦3♥2♠5♦ (pot 14): he does not fold a pair, so a bluff just burns money — check. And facing a bet from someone who bluffs far too much, with 9♥8♥ on Q♠9♦5♣3♥2♠ (11 into 16, need 29%): second pair is normally a close decision; against him it is a call.

Common mistake: 'exploiting' without a read — calling a big river bet because he might be a maniac. Without evidence, the baseline is the best guess; deviations need a reason you can name.

Vs tight players

A tight, passive player makes two mistakes at once: he folds too often when he has not connected, and he bets or raises only when he has. Both can be used. Bluff him more on the flop and on cards that look scary, because he gives up without a pair. And believe him: when a nit bets big or raises, your bluff-catchers are beaten far more often than the price suggests, so hands that would normally call become folds. One limit matters. When a nit checks after raising preflop and continues only with monsters, a bet from pure air gains nothing — what folds was never paying you, and what continues has you crushed. Bluff him when his range still holds many hands that fold.

Example. Flop K♠8♦3♣, pot 8: villain folds far too often to c-bets and you hold Q♥J♥ — bet, the hand hardly matters. Turn Q♠7♦2♣A♥ with J♦T♣ first to act (pot 10): the ace is a scare card a nit will not fight for — bet. Now the other side. River K♠Q♦8♣5♥2♠: a nit who only bets strong hands fires 14 into 16 and you hold K♥J♥. You need 32%, and top pair would often call — against him, fold. Turn 9♠8♦7♣4♥ with A♠A♦: you bet and a passive player who never bluff-raises raises (10 to call, pot 14) — fold the overpair.

Common mistake: bluffing a nit and then also paying him off. The read says the same thing in both directions: his folds are frequent and his bets are real.

Vs calling stations

A calling station's mistake is that he does not fold. That removes your bluffs — the fold equity a bluff needs does not exist — and it widens your value range: hands that would check against a good player become bets, because he calls with third pair and ace-high. Bet bigger with strong hands as well; he pays the same range either way. The over-aggressive player is the mirror image. He bets too often, so your medium hands gain value as bluff-catchers and lose value as bets: checking to him earns more than betting, because he bluffs with hands that would have folded. Against him call wider, even with ace-high and against overbets, and give him the rope on earlier streets.

Example. Station: river Q♥J♦4♣2♠8♥ with J♣T♠ first to act (pot 18) — second pair bets for value. River A♠J♦6♣3♥2♠ with A♣T♣ checked to you (pot 14) — bet. But A♠Q♠ on J♥9♣5♦4♠2♥ after he checks: ace-high cannot make him fold a pair — check. Over-bluffer: river K♠9♦5♣3♥2♠ with K♥T♥ out of position (pot 16) — check and call, do not bet. River K♠J♦9♥5♣2♠ with K♥Q♥ facing an overbet of 20 into 16: you need 36%, and against someone who over-bluffs rivers top pair with a good kicker calls. Even A♥T♥ on K♠Q♦7♣5♥2♠ facing 10 into 16 (need 28%) is a call against him.

Common mistake: trying to bluff a calling station 'because he has to fold sometime'. He does not — that is the read. Wait for a hand and charge him.

Key takeaways

• Villain folds too much → c-bet and barrel scare cards with air; raise draws for fold equity.
• A nit bets big or raises (need about 30%) → fold one-pair hands that would normally call, even an overpair.
• Calling station → never bluff; value bet second pair and weak top pair, and size up with strong hands.
• Villain bluffs too much → check your medium hands to him and call, even facing an overbet (need 36%).
• No read → play the baseline; deviate only for a mistake you have actually seen.
