In equity, TT against 77 stands at 81.25% to 18.75%, a gap of 62.50 points. ## TT against 77: the numbers **Exact preflop results for TT against 77, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | TT | 81.010 | 0.474 | 18.516 | 81.247 | | 77 | 18.516 | 0.474 | 81.010 | 18.753 | Both hands are pocket pairs: TT and 77. 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: 77 needs the board to help it on most runouts and still falls behind far more often than not. Ties are 0.47% of the outcomes here; each tied board gives both hands half the pot. Among the 169 starting hands, TT is number 5 and 77 is number 9 by strength against a random hand. **Boards behind the percentages: 61,642,944 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | TT | 49,937,000 | 292,000 | 11,414,000 | | 77 | 11,414,000 | 292,000 | 49,937,000 | 36 specific deals times 1,712,304 boards gives the exact total.

TT's equity of 81.25% is worth $162.50, a $62.50 edge, and 77's 18.75% is worth $37.50, which is $62.50 under its stake.
