Adjustments against common mistakes
While GTO strategy protects you from exploitation, it doesn't maximize profit against players who make significant mistakes. Exploitative play means deliberately deviating from balanced strategy to take advantage of specific leaks in your opponents' games.
The key principle is simple: if an opponent does something too much, do the opposite. If they call too much, bet more for value and bluff less. If they fold too much, bluff more and value bet thinner. Every deviation from optimal play creates an opportunity for you to profit.
Warning: Exploitative adjustments make you exploitable in return. If your opponent adapts, you need to re-adjust. Always be aware of whether opponents are capable of counter-adjusting.
Calling stations are the most profitable opponents in poker. They call too often with too-weak hands, paying off your value bets street after street. Against them, the adjustments are straightforward:
Hands that would normally be too thin to value bet (like second pair or weak top pair) become profitable bets against players who call with bottom pair, ace-high, or even king-high. If they'll call with worse, bet for value.
Bluffing a calling station is lighting money on fire. They don't fold, so every bluff is money lost. Remove bluffs from your range entirely against these players and replace them with thin value bets.
You have A-J on a board of A-7-3-9-2 against a known calling station. What should you do on the river?
Tight players and nits have the opposite leak — they fold too much. This makes them vulnerable to aggression and stealing. The profit comes from all the small pots you win uncontested.
Steal Their Blinds
If a player folds their blinds more than 75% of the time, you can profitably open-raise with any two cards from the button or cutoff. The math is simple: if you risk 2.5 big blinds to win 1.5 big blinds, you only need them to fold 62% of the time.
Bluff More Aggressively
Continue betting on scary board cards (aces, flush completions, paired boards). Nits without a strong hand will fold, and you can represent a wide range of made hands. Multiple-barrel bluffs are highly effective against tight opponents.
Respect Their Aggression
When a nit raises or re-raises, believe them. Fold your marginal hands without guilt — they have the goods. Save your calling chips for situations where you have a strong hand yourself.
When you identify a fish at the table, your top priority is playing pots with them — preferably heads-up with position. Isolation raises accomplish this by raising after the fish limps, forcing tighter players to fold and leaving you alone against the weakest opponent.
Size your isolation raises larger than normal (3-4x the big blind plus one more for each limper) to discourage other players from calling. You want a heads-up pot in position against the weakest player at the table.
Key Insight: Seat selection matters. If possible, always sit to the left of the weakest player so you have position on them for the entire session.
A nit in the big blind folds to steals 80% of the time. You're on the button. What is the most profitable play?
Preflop
Your Hand
A known calling station limps from middle position. You are on the cutoff with K-T offsuit. Two tighter players are behind you.
