For context, KJs sits at number 20 of 169 starting hands and 64s at number 138 when each is run against a random hand.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |
|---|---|---|---|

| 64s | 9,994,000 | 195,000 | 17,207,000 |
16 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) |
|---|---|---|---|---|
| KJs | 1.715 | 1.592 | 2.741 | 0.583 |
| 64s | 0.583 | 2.741 | 1.592 | 1.715 |
In the last column, a pot-to-call ratio at or above the figure makes a call break even or better at this equity.
