The exact count puts AA at 81.77% and 33 at 18.23% when the two hands see all five board cards. ## AA against 33: the numbers **Exact preflop results for AA against 33, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | AA | 81.526 | 0.490 | 17.984 | 81.771 | | 33 | 17.984 | 0.490 | 81.526 | 18.229 | This is a contest between two pocket pairs, AA and 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. About 0.49% of boards chop the pot, which is why equity sits slightly above the win figure for both hands. The hand ranking puts AA at 1 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 | | --- | --- | --- | --- | | AA | 50,255,000 | 302,000 | 11,086,000 | | 33 | 11,086,000 | 302,000 | 50,255,000 | 36 specific deals times 1,712,304 boards gives the exact total.
