66 against 44: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| 66 | 80.418 | 1.970 | 17.612 | 81.403 |
| 44 | 17.612 | 1.970 | 80.418 | 18.597 |
This is a contest between two pocket pairs, 66 and 44. Two pairs against each other is a one-way street: the lower pair needs one of its two remaining cards.
That is a heavy lead: 44 needs the board to help it on most runouts and still falls behind far more often than not. Of every 100 boards, about 1.97 are split pots, and the equity figures already include them.
In the ranking of all 169 starting hands, 66 is number 17 and 44 is number 48.
