Counting every board, the equity split is 81.34% for 99 and 18.66% for 33, so 99 leads by 62.68 points. ## 99 against 33: the numbers **Exact preflop results for 99 against 33, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | 99 | 80.974 | 0.725 | 18.301 | 81.337 | | 33 | 18.301 | 0.725 | 80.974 | 18.663 | Each side holds one of the pocket pairs: 99 and 33. A pair against a smaller pair is the classic crush: the smaller pair needs one of its two remaining cards to make a set. A gap this wide means 33 is in trouble before the flop and has few good runouts. A split pot comes up on 0.73% of boards, so the wins and the equity differ by half of that. By strength against a random hand, 99 holds place 6 of 169 and 33 holds place 66. **Boards behind the percentages: 61,642,944 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | 99 | 49,915,000 | 447,000 | 11,281,000 | | 33 | 11,281,000 | 447,000 | 49,915,000 | Exact total: 36 deals times 1,712,304 boards.
