KK against 87s: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| KK | 77.753 | 0.362 | 21.885 | 77.934 |
| 87s | 21.885 | 0.362 | 77.753 | 22.066 |
KK is a pocket pair and 87s is a suited hand. A pair against two lower cards is a lopsided matchup: the pair is ahead and the other hand has no overcard to catch.
That is a clear edge, 77.93% to 22.07%, but 87s still wins often enough that one hand proves nothing. A split pot comes up on 0.36% of boards, so the wins and the equity differ by half of that.
Among the 169 starting hands, KK is number 2 and 87s is number 100 by strength against a random hand.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |
|---|---|---|---|
| KK | 31,953,000 | 149,000 | 8,994,000 |
| 87s | 8,994,000 | 149,000 | 31,953,000 |
24 specific deals times 1,712,304 boards gives the exact total. The won, tied and lost counts are approximations from the five-decimal percentages, rounded to the nearest thousand.
| Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) |
|---|---|---|---|---|
| KK | 3.532 | 1.286 | 4.569 | 0.283 |
| 87s | 0.283 | 4.569 | 1.286 | 3.532 |
The final column gives the least the pot must offer for each unit called for a call to break even at this equity.

Each figure is a complete count over boards. Take the 24 specific deals, group them by suit pattern, deal all 1,712,304 boards against each, and compare the two seven-card hands. Equity counts a tie as half a win; the flop rows use every one of a board's ten flops.
