88 against 66: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| 88 | 80.981 | 0.927 | 18.092 | 81.444 |
| 66 | 18.092 | 0.927 | 80.981 | 18.556 |
Here pocket pairs face each other, 88 on one side and 66 on the other. A pair against a smaller pair is the classic crush: the smaller pair needs one of its two remaining cards to make a set.
That is a heavy lead: 66 needs the board to help it on most runouts and still falls behind far more often than not. About 0.93% of boards chop the pot, which is why equity sits slightly above the win figure for both hands.
The hand ranking puts 88 at 7 and 66 at 17 out of 169 starting hands.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |

| 66 | 11,152,000 | 571,000 | 49,919,000 |
The total is exact: 36 specific deals times 1,712,304 boards. The three counts are approximate, worked out from the percentages to five decimals and rounded to the nearest thousand.
