Dealt all in against each other, KK takes 81.37% of the pot on average and 33 takes the other 18.63%. ## KK against 33: the numbers **Exact preflop results for KK against 33, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | KK | 81.121 | 0.492 | 18.387 | 81.367 | | 33 | 18.387 | 0.492 | 81.121 | 18.633 | The matchup is pocket pairs on both sides, KK against 33. Both hands are pairs, so the bigger pair is ahead on every board that does not pair a card below it. That is a heavy lead: 33 needs the board to help it on most runouts and still falls behind far more often than not. A split pot comes up on 0.49% of boards, so the wins and the equity differ by half of that. The hand ranking puts KK at 2 and 33 at 66 out of 169 starting hands. **Boards behind the percentages: 61,642,944 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | KK | 50,005,000 | 303,000 | 11,334,000 | | 33 | 11,334,000 | 303,000 | 50,005,000 | Exact total: 36 deals times 1,712,304 boards.
