Exploit
A strategy that deviates from GTO to exploit opponent mistakes
Definition
Exploitative play deliberately abandons GTO equilibrium to maximize profit against a specific opponent who has imbalances. Unlike GTO, which is optimal against any opponent, exploit is maximally profitable against a particular player but can in turn be exploited by an opponent who adjusts. Exploiting consists of identifying opponent leaks and targeting them directly: if a player folds too often to c-bets, you increase your c-bet-bluff frequency. If a player calls too much on the river, you value-bet thinner and bluff less. If a player 3-bets too much, you 4-bet wider. The best approach is to learn GTO as a baseline, then deviate from it to exploit imbalanced opponents. In online poker with a HUD, opponent stats let you identify these imbalances quickly.
Your opponent has a fold-to-c-bet of 70% (too high — optimal is ~45–50%). You go from 50% to 80% c-bet frequency against him. Each extra bet becomes pure profit at no risk.
