Do you have the odds to call with an open-ended straight draw?
An open-ended straight draw has 8 outs, about 32% equity on the flop and 16% on the turn.
Eight cards make your straight, giving about 32% on the flop and 16% on the turn. On the flop a bare open-ender can call up to roughly a pot-sized bet; on the turn the price tightens and you usually need a smaller bet or strong implied odds to continue.
On direct pot odds, 8 outs lets you profitably call a flop bet up to about 89% of the pot. Deeper stacks and implied odds push that higher.
Quick tip: Open-ended draw on the flop is about 32%, just short of a pot-sized bet by itself.
