T8s against 64s: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| T8s | 62.844 | 1.844 | 35.312 | 63.766 |
| 64s | 35.312 | 1.844 | 62.844 | 36.234 |
Each side holds one of the suited hands: T8s and 64s. Neither hand shares a rank with the other, so this is a contest of high cards, connection and suits.
That is a modest edge, the kind that shows up over many hands and is easy to miss in one. Split pots make up 1.84% of the boards, and both equity figures count them as half a win each.
Place 73 of 169 belongs to T8s and place 138 belongs to 64s in the ranking against a random hand.
