77 against JTs: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| 77 | 49.040 | 0.520 | 50.440 | 49.300 |
| JTs | 50.440 | 0.520 | 49.040 | 50.700 |
77 and JTs are a pocket pair and a suited hand, in that order. 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.
This is close to even money, with JTs a little ahead. A split pot comes up on 0.52% of boards, so the wins and the equity differ by half of that.
For context, 77 sits at number 9 of 169 starting hands and JTs at number 45 when each is run against a random hand.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |
|---|---|---|---|
| 77 | 20,153,000 | 214,000 | 20,728,000 |
| JTs | 20,728,000 | 214,000 | 20,153,000 |
24 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) |
|---|---|---|---|---|
| 77 | 0.972 | 2.039 | 1.983 | 1.028 |
| JTs | 1.028 | 1.983 | 2.039 | 0.972 |
In the last column, a pot-to-call ratio at or above the figure makes a call break even or better at this equity.
