You need one exact rank in the middle of the straight. Four cards make it.
Pot equity and pot odds
The chart tells you what to open. Once there is a bet in front of you after the flop, two numbers decide whether a call makes money: how often your hand wins, and what price the pot is offering. Both are quick to estimate at the table.
Equity
Equity is the share of the pot your hand wins on average if every remaining card came out. Count your outs, the unseen cards that turn your hand into the best one, then use the rule of two and four. On the flop, multiply outs by four for your chance by the river. On the turn, multiply by two.
The common draws
Each example shows your hand, the flop, and every card that completes the draw.

Nine hearts plus the three jacks and three sixes that are not hearts. Fifteen cards, and a favorite against one pair.
If an out also improves the other player, count it as half. With more than eight outs on the flop, subtract the extra outs from the rule-of-four result: fifteen outs is 60 minus 7, about 53%.
Pot odds
Pot odds are the equity you need for a call to break even. Divide the bet by the pot after both of you have put the bet in.
required equity = bet ÷ (pot + bet + bet)
Villain bets 5 bb into a 10 bb pot. You need 5 ÷ (10 + 5 + 5) = 25%. A flush draw on the flop has about 36%, so calling makes money. If the bet were 15 bb into the same pot, you would need 15 ÷ 40 = 37.5%, and the same draw is a fold.
Do it in your head
- Count outs, then times four or times two. Flop, times four. Turn, times two.
- Size the bet against the pot, not in chips. Half pot, full pot, and so on. The required equity depends only on that fraction, so memorize five numbers.
- Compare. Equity above the number, call. Below it, fold.
| Bet | You need | Rule of thumb |
|---|---|---|
| Quarter pot | 17% | a gutshot on the flop calls |
| Half pot | 25% | an open-ender or flush draw on the flop calls |
| Two-thirds pot | 29% | eight outs on the flop is a close call |
| Full pot | 33% | a flush draw on the flop still calls, a straight draw does not |
| Twice the pot | 40% | only combo draws and made hands continue |
On the turn every draw is worth half as much, so the same flush draw at 18% only calls a quarter-pot bet.
Put them together
Call when your equity is higher than the required equity. Fold when it is lower. Everything else, from implied odds to fold equity, adjusts these two numbers, so get them automatic first.
