Bet Sizing in Poker

Bet sizing is one of the most misunderstood concepts in poker, especially for developing players. Most beginners size their bets based on how strong they feel, not based on what the bet is designed to accomplish. That's backwards. Every bet has a job. A value bet extracts money from worse hands. A bluff folds out better hands. A protection bet denies equity to draws. The size of the bet should be calibrated to do that job efficiently — not to "look strong" or "see where I'm at." For value betting, you want to bet an amount your opponent will call with a worse hand. If they'll call $50 but fold to $100, bet $50. Leaving money on the table by betting too small, or losing a call by betting too large, both cost you. Think about your opponent's calling range before you pick a size. For bluffing, your size needs to make the bet credible and the fold mathematically correct for your opponent. A bluff that's too small invites calls. A bluff that's too large is expensive when it fails. In position, smaller bluffs often work because your opponent must act first and is already showing weakness. Out of position, you sometimes need to apply more pressure. Pot-sized bets are roughly 67% pot. Half-pot bets are 33%. Quarter-pot bets are about 20%. Knowing what equity your opponent needs to call at each size lets you pick sizes that target the right calling range. Consistency matters too. If you bet big with strong hands and small with bluffs, thinking players will exploit you. Mix your sizings across your range at the same frequency so your bet size alone reveals nothing.
