| Flush + OESD (Combo) | 15 | 54.1% | 32.6% |

The 4/2 approximation: Multiply your outs by 4 on the flop (with 2 cards to come), or by 2 on the turn. It’s a quick estimate — the calculator above gives the exact number.
When does calling actually pay? When your equity exceeds the equity required by the pot odds. Careful — in multiway pots your effective equity drops, and if the opponent can bet more later (reverse implied odds), you need far more.
