JTs against J9s: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| JTs | 64.026 | 9.888 | 26.086 | 68.970 |
| J9s | 26.086 | 9.888 | 64.026 | 31.030 |
This is a contest between two suited hands, JTs and J9s. Sharing a rank is the signature of a dominated hand, since the weaker hand is usually out-kicked when the shared rank shows up.
That is a clear edge, 68.97% to 31.03%, but J9s still wins often enough that one hand proves nothing. A split pot comes up on 9.89% of boards, so the wins and the equity differ by half of that.
The hand ranking puts JTs at 45 and J9s at 55 out of 169 starting hands.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |
|---|---|---|---|
| JTs | 13,156,000 | 2,032,000 | 5,360,000 |
| J9s | 5,360,000 | 2,032,000 | 13,156,000 |
12 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) |
|---|---|---|---|---|
| JTs | 2.223 | 1.562 | 3.833 | 0.450 |
| J9s | 0.450 | 3.833 | 1.562 | 2.223 |
The last column is the smallest pot odds, written as a pot-to-call ratio, at which a call breaks even with this equity.

|---|---|---|---|---|---|---|
| Share a suit | 0 | 0.00 | not possible | not possible | not possible | not possible |
