Averaged over every possible board, 88 is ahead of 64s by 61.20 points of equity, 80.60% to 19.40%. ## 88 against 64s: the numbers **Exact preflop results for 88 against 64s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | 88 | 80.134 | 0.925 | 18.941 | 80.596 | | 64s | 18.941 | 0.925 | 80.134 | 19.404 | Here a pocket pair (88) meets a suited hand (64s). Here a pair faces two cards that are both smaller, so the other hand needs to pair up and still be behind. That is a heavy lead: 64s needs the board to help it on most runouts and still falls behind far more often than not. The tie share is 0.93%: on those boards the pot is chopped and neither hand wins outright. 88 ranks number 7 of 169 starting hands, and 64s ranks number 138, 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 | | --- | --- | --- | --- | | 88 | 32,931,000 | 380,000 | 7,784,000 | | 64s | 7,784,000 | 380,000 | 32,931,000 | 24 specific deals times 1,712,304 boards gives the exact total.
