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

| JTo | 60,965,000 | 743,000 | 61,578,000 |
Exact total: 72 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.
| Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) |
|---|---|---|---|---|
| 66 | 1.010 | 2.002 | 2.022 | 0.990 |
| JTo | 0.990 | 2.022 | 2.002 | 1.010 |
In the last column, a pot-to-call ratio at or above the figure makes a call break even or better at this equity.
