What is an overbet in poker?
An overbet is a bet larger than the pot, for example betting $150 into a $100 pot. It puts maximum pressure on your opponent. It works best when your range has many very strong hands that your opponent can’t have, plus some bluffs, and your opponent’s hand is capped at medium strength.
Why overbet?
Section titled “Why overbet?”- Maximum value from strong hands when your opponent has a good but not great hand they don’t want to fold.
- Maximum fold pressure with bluffs: a bluff has to work more often, but it also forces folds from better hands. See when to bluff.
When it works
Section titled “When it works”- Your opponent’s range is capped: their actions show they rarely have the nuts (for example, they called twice instead of raising).
- You have the nut advantage: more of the very best hands in your range. Example: you raised preflop, the board runs A-K-x-x-x, and you can hold A-K or sets.
- On the turn or river, where hands are more defined.
- Overbetting medium hands is a mistake: only better hands call.
- If you only overbet with the nuts, observant players will fold.
- Overbet bluffs lose more when called.
How often must a bluff work?
Section titled “How often must a bluff work?”| Bet size | Bluff must work at least |
|---|---|
| Pot | 50% |
| 1.5× pot | 60% |
| 2× pot | 67% |
Facing an overbet
Section titled “Facing an overbet”- At low stakes, big overbets are usually strong hands. Fold medium hands more.
- Use blockers and ranges to decide close calls.
- You need to win more often to call: against a pot-sized bet you need 33% equity; against 2× pot, 40%. See pot odds.
For beginners, standard sizes are usually enough. See bet sizing.
