K9o leads 58.98% to 41.02% before the flop, counted exactly over every board, with the split by flop type and suit. Counting every board, the equity split is 58.98% for K9o and 41.02% for 65s, so K9o leads by 17.96 points. ## K9o against 65s: the numbers **Exact preflop results for K9o against 65s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | K9o | 58.638 | 0.679 | 40.683 | 58.978 | | 65s | 40.683 | 0.679 | 58.638 | 41.022 | K9o is an offsuit hand and 65s is a suited hand. Neither hand shares a rank with the other, so this is a contest of high cards, connection and suits. K9o is ahead, but 65s is far from dead: it takes 407 of every 1,000 deals outright. 0.68% of boards are ties, so the equity of each hand is its win rate plus half of that. For context, K9o sits at number 40 of 169 starting hands and 65s at number 128 when each is run against a random hand. **Boards behind the percentages: 82,190,592 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | K9o | 48,195,000 | 558,000 | 33,438,000 | | 65s | 33,438,000 | 558,000 | 48,195,000 | 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. **K9o against 65s read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | K9o | 1.438 | 1.705 | 2.458 | 0.696 | | 65s | 0.696 | 2.458 | 1.705 | 1.438 | In the last column, a pot-to-call ratio at or above the figure makes a call break even or better at this equity. ## Who is ahead on which flops The flop changes the picture. K9o does best on rainbow flops topped by a ten or better, at 64.58%, and worst on low rainbow flops (nine high or lower), at 39.64%.
