| Bet Size | Required Equity | Example | Meaning |
|---|---|---|---|
| 25% pot | 16.7% | Pot 100, villain bets 25, call 25 to win 150. | Small bet; many draws and bluff-catchers can continue. |
| 33% pot | 20.0% | Pot 100, villain bets 33, call 33 to win 166. | Common range bet sizing needing modest equity. |
| 50% pot | 25.0% | Pot 100, villain bets 50, call 50 to win 200. | You need one win in four calls to break even. |
| 75% pot | 30.0% | Pot 100, villain bets 75, call 75 to win 250. | Medium-large pressure; weak draws need implied odds. |
| 100% pot | 33.3% | Pot 100, villain bets 100, call 100 to win 300. | Pot-sized bet; continue with strong equity or blockers. |
