What Is a Combo Draw in Poker?
A combo draw pairs a flush draw with a straight draw for 12 to 15 outs, often making it a favourite against one pair. Learn the real equities.
A combo draw is a hand holding two draws at once, almost always a flush draw sitting alongside a straight draw. That pairing gives you 12 to 15 outs instead of the eight or nine a single draw offers, which is worth roughly 45% to 54% equity by the river. The strongest version is a favourite against top pair, which is why a combo draw is a hand you raise with rather than call.
Counting the outs
The two draws overlap, and that is where the maths usually goes wrong. A flush draw has nine outs and an open-ender has eight, but two of those straight cards are already in your suit and have been counted once. Fifteen, not seventeen.
| Draw | Outs | Equity flop to river |
|---|---|---|
| Open-ended straight draw | 8 | 32% |
| Flush draw | 9 | 35% |
| Flush draw plus gutshot | 12 | 45% |
| Flush draw plus open-ender | 15 | 54% |
The rule of 4 is close enough for a bare flush draw and overshoots badly up here, calling 15 outs 60% when the real figure is 54%. Against a range rather than one hand the number moves again, so put the exact spot into the poker equity calculator before you decide how much you are willing to get in.
Two draws that share cards are worth less than the sum of their outs. Count the overlap first, then count your equity.

A hand that shows it
You hold 9♠8♠ on the BTN and the flop comes Q♠7♠6♥. Nine spades, four tens and four fives, minus the T♠ and 5♠ you have already counted: 15 outs.
Against Q♥J♦, the top pair that bets this flop every time, you are about 54% to win by the river. You are not drawing at all in the ordinary sense. You are the favourite, and the made hand is the one with the problem.
Playing it fast
Raise. The pot is $60, your opponent bets $40, you make it $130. Even if they never fold, you are putting money in with better than half the equity against the hands that call, and every fold from a marginal queen is profit stacked on top of that.
Calling wastes both halves. You give up the fold equity, you let a blank turn kill your price, and you reach the river with a busted hand you cannot represent. Two draws are aggression, not patience.
The weaker version deserves respect for what it is. Q♦J♦ on K♦9♦4♣ is a flush draw plus a gutshot, since only a ten completes the straight: nine diamonds plus three non-diamond tens, so 12 outs and 45% equity. Strong enough to raise a single bet, not strong enough to be thrilled about a 200bb stack going in against a set.
