Counting every board, the equity split is 50.53% for 75s and 49.47% for 33, so 75s leads by 1.06 points. ## 33 against 75s: the numbers **Exact preflop results for 33 against 75s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | 33 | 48.330 | 2.288 | 49.382 | 49.474 | | 75s | 49.382 | 2.288 | 48.330 | 50.526 | One side is a pocket pair, the other is a suited hand. This is a pair against two overcards, a matchup that stays close because the other hand only needs one of its ranks to appear. This is close to even money, with 75s a little ahead. Ties are part of the picture: 2.29% of boards end in a split pot, and each side counts that as half a win. 33 ranks number 66 of 169 starting hands, and 75s ranks number 124, by equity against a random hand. **Boards behind the percentages: 41,095,296 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | 33 | 19,861,000 | 940,000 | 20,294,000 | | 75s | 20,294,000 | 940,000 | 19,861,000 | The total is exact: 24 specific deals times 1,712,304 boards. The three counts are approximate, worked out from the percentages to five decimals and rounded to the nearest thousand. **33 against 75s read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | 33 | 0.979 | 2.069 | 2.025 | 1.021 | | 75s | 1.021 | 2.025 | 2.069 | 0.979 | The last column is the break-even price: the pot odds a call needs to offer, as a ratio of pot to call. ## Who is ahead on which flops Across the five flop textures 75s' equity moves by 13.80 points, from 47.00% on paired flops to 60.80% on low rainbow flops (nine high or lower). Rainbow flops topped by a ten or better and paired flops favor 33, the hand that is behind overall. **33 against 75s by flop texture, in percent** | Flop | Share of flops | 33 wins | Ties | 75s wins | 33 equity | | --- | --- | --- | --- | --- | --- | | Rainbow, ten or higher | 25.844 | 51.338 | 1.338 | 47.324 | 52.007 | | Rainbow, nine or lower | 5.065 | 38.749 | 0.913 | 60.338 | 39.205 | | Two-tone | 46.545 | 47.298 | 1.204 | 51.498 | 47.900 | | Monotone | 5.212 | 47.278 | 3.893 | 48.829 | 49.225 | | Paired | 17.334 | 49.733 | 6.536 | 43.731 | 53.001 | Read the flop types this way: rainbow has three suits, two-tone has two cards of one suit, monotone has three, and paired repeats a rank. ## Compared with a random hand Start from the random-hand figures, 53.69% for 33 and 43.68% for 75s.
