Combo Draw: Exact Equity Against Top Pair, Overpair and Set
A combo draw is a flush draw and a straight draw in the same hand, usually 15 outs on the flop. That makes it a favorite against top pair: J♥T♥ on 9♥ 8♥ 2♣ has 68.9% against A♠9♠. Against an overpair it is close to a coin flip (49.4% to 56.3%), and against a set it is behind at 42.1%. After a blank turn, every figure loses roughly a third of its value, or more.
A combo draw facing a big turn bet
J♠T♠ on the button: on Q♠ 9♦ 4♣ then 2♠, you hold a flush draw and a straight draw at once, and the big blind leads for 125% of the pot. Fold, call or raise?
See the answer
Your combo draw. Flush draw plus open-ended straight draw: 15 outs with one card to come, 34.1% even against an overpair of aces.
The decision. The expected answer is to call: the bet requires a bit more than a third in equity, the draw is close to it, and the straights and flushes you hit win more on the river.
