66, a pocket pair, plays T8s, a suited hand. A pair against two higher cards is the classic race: the pair is usually a small favorite or close to even, and each overcard that pairs is a way to take the lead.

| Hand | Boards won, about | Boards tied, about | Boards lost, about |

| T8s | 20,265,000 | 308,000 | 20,523,000 |
Exact total: 24 deals times 1,712,304 boards. The other three counts come from the five-decimal percentages and are rounded to the nearest thousand, so read them as approximate.

| T8s | 0.988 | 2.028 | 2.002 | 1.013 |
