Pick your hand and the board to see every out, how clean it is, and the exact odds.
| Next card | By the river | |
|---|---|---|
| Exact (all outs) | 31.9% | 54.1% |
| Exact (dirty discounted) · 14.5 | 30.9% | 52.6% |
| Rule of 2 / 4 | 30% | 60% |
| Rule, big-draw correction | — | 53% |
Use the rule of 4 on the flop (outs × 4) and the rule of 2 on the turn (outs × 2). With more than 8 outs the rule of 4 overshoots; a common correction subtracts (outs − 8).
You hold a flush draw (9 hearts) plus two overcards (3 aces, 3 kings): 15 outs. The 2♥ pairs the board with the 2♣, so a full house is possible for an opponent: it is a dirty out and the other 14 are clean. The exact chance by the river is 54.1%. The rule of 4 gives 60%, about 6 points too high; subtracting (15 − 8) gives 53%, much closer.
