Averaged over every possible board, QJo is ahead of 64s by 22.02 points of equity, 61.01% to 38.99%. ## QJo against 64s: the numbers **Exact preflop results for QJo against 64s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | QJo | 60.557 | 0.904 | 38.539 | 61.009 | | 64s | 38.539 | 0.904 | 60.557 | 38.991 | Here an offsuit hand (QJo) meets a suited hand (64s). Neither hand shares a rank with the other, so this is a contest of high cards, connection and suits. That is a modest edge, the kind that shows up over many hands and is easy to miss in one. Ties are 0.90% of the outcomes here; each tied board gives both hands half the pot. The hand ranking puts QJo at 39 and 64s at 138 out of 169 starting hands. **Boards behind the percentages: 82,190,592 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | QJo | 49,772,000 | 743,000 | 31,675,000 | | 64s | 31,675,000 | 743,000 | 49,772,000 | Exact total: 48 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. **QJo against 64s read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | QJo | 1.565 | 1.651 | 2.595 | 0.639 | | 64s | 0.639 | 2.595 | 1.651 | 1.565 | The last column is the smallest pot odds, written as a pot-to-call ratio, at which a call breaks even with this equity. ## Who is ahead on which flops Across the five flop textures QJo's equity moves by 35.40 points, from 34.27% on low rainbow flops (nine high or lower) to 69.67% on rainbow flops topped by a ten or better.

Looking only at deals where the hands share a suit, QJo has 61.73%; looking only at deals where they do not, 60.29%. QJo does better with a shared suit, by 1.44 points. **QJo against 64s by suit overlap, in percent** | Deals | Specific deals | Share of deals | QJo wins | Ties | 64s wins | QJo equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 24 | 50.00 | 61.258 | 0.946 | 37.796 | 61.731 | | No shared suit | 24 | 50.00 | 59.857 | 0.863 | 39.280 | 60.288 | ## How often this matchup comes up The class pair covers 48 combinations of specific cards in a fixed seat order, 0.0030% of 1,624,350, and 96 (0.0059%) in either order. ## A worked example With $100 from each side, the $200 pot is split on average as $122.02 for QJo and $77.98 for 64s; the first side gains $22.02 per all-in and the second gives up $22.02.
