A combo draw is a hand with two draws at once, most often a flush draw plus a straight draw. Combo draws have so many outs that they are often favourites even against a made hand like top pair, which changes how you should play them.
Combo draw odds
| Draw | Outs | Flop to turn | Turn to river | Flop to river |
|---|---|---|---|---|
| Flush draw + open-ender | 15 | 31.9% | 32.6% | 54.1% |
| Flush draw + gutshot | 12 | 25.5% | 26.1% | 45.0% |
| Flush draw + two overcards | 15 | 31.9% | 32.6% | 54.1% |
| Open-ender + pair | 13 | 27.7% | 28.3% | 48.1% |
The biggest common draw, a flush draw plus an open-ender, has 15 outs: 9 flush cards plus 6 more straight cards that are not already counted. It hits on the turn 31.9% of the time and by the river 54.1% of the time, so with two cards to come it completes more often than it misses.
Overcards and pairs are less reliable outs. Pairing an ace with ace-high may not be the best hand, so count those outs at less than full value. The pair-plus-open-ender row assumes your five pairing cards would all give you the best hand.
How the outs add up
Count each card only once. With 9-8 of hearts on a 7-6-2 board with two hearts, the nine hearts complete the flush and the eight cards that make a straight include the five and ten of hearts, which are already counted. That leaves 9 + 6 = 15 outs. With a gutshot instead of an open-ender, 9 + 3 = 12.
How to play a big combo draw
- Be aggressive. With 54.1% equity over two cards, getting all-in on the flop is usually fine against one pair, and betting or raising also wins the pot outright when they fold.
- Watch what beats you. If your flush is low or the board pairs, some outs may not be clean.
- Use the right number. With one card to come the 15-outer is 31.9%, a big drop from 54.1%. If you are not all-in, price the call one card at a time.
