Bet sizing varies based on your goals, the board texture, and your opponents. In general, larger bets are used when you want to protect a strong hand, extract maximum value, or apply pressure with a bluff. Smaller bets can control the pot size, extract value from marginal hands, or probe for information. In multi-way pots, bets are often larger to reduce the number of opponents continuing. On wet or draw-heavy boards, bigger bets discourage chasing draws, while smaller bets are more effective on dry boards where fewer hands can improve. Adapting your bet size based on position, stack depth, and the tendencies of your opponents is crucial for optimal play.
