How outs are counted
An out here is a card that gives you two pair or better with at least one of your own cards playing. A card that only pairs the board is left out, because it helps every hand at the table the same. Cards that pair one of your hole cards are listed apart: a pair is often not enough to win. On a paired board, pairing one of your cards gives two pair on paper but only one pair of your own, so it is listed there too. An outlined out still helps you but could also give an opponent a better hand, such as a flush card that pairs the board.
Outs and the odds of hitting
| Draw | Outs | Flop to river | Turn to river |
|---|---|---|---|
| Gutshot straight draw | 4 | 16.5% | 8.7% |
| Two overcards, pairing either one | 6 | 24.1% | 13.0% |
| Open-ended straight draw | 8 | 31.5% | 17.4% |
| Flush draw | 9 | 35.0% | 19.6% |
| Flush draw and a gutshot | 12 | 45.0% | 26.1% |
| Flush draw and an open-ender | 15 | 54.1% | 32.6% |
The overcard row counts the 6 cards that pair one of your two overcards. They make one pair, so the calculator above lists them with the cards that only make a pair and leaves them out of its outs.
A worked example
The page opens on J♥ 9♥ with a flop of 10♥ 8♣ 2♥. Any heart makes a flush (9 outs), and a queen or a seven makes a straight. Two of those eight straight cards are hearts already counted, so the total is 15 outs and a 54.1% chance by the river. Compare the chance with the price of a call in the pot odds calculator, or run the draw against a real hand in the poker odds calculator.
