JTo against 64s: the numbers
| Hand | Wins | Ties | Loses | Equity |
|---|---|---|---|---|
| JTo | 61.206 | 1.144 | 37.650 | 61.778 |
| 64s | 37.650 | 1.144 | 61.206 | 38.222 |
One side is an offsuit hand, the other is a suited hand. With no overlap in ranks, every card that pairs one hand is a card that does not pair the other.
A 23.56 point lead is real, and 64s still takes about 377 of every 1,000 deals outright. About 1.14% of boards chop the pot, which is why equity sits slightly above the win figure for both hands.
In the ranking of all 169 starting hands, JTo is number 57 and 64s is number 138.
| Hand | Boards won, about | Boards tied, about | Boards lost, about |
|---|---|---|---|
| JTo | 50,306,000 | 940,000 | 30,945,000 |
| 64s | 30,945,000 | 940,000 | 50,306,000 |
48 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) |
|---|---|---|---|---|
| JTo | 1.616 | 1.634 | 2.656 | 0.619 |
| 64s | 0.619 | 2.656 | 1.634 | 1.616 |
The last column is the smallest pot odds, written as a pot-to-call ratio, at which a call breaks even with this equity.
