Counting every board, the equity split is 60.44% for KJo and 39.56% for 53s, so KJo leads by 20.88 points. ## KJo against 53s: the numbers **Exact preflop results for KJo against 53s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | KJo | 60.077 | 0.716 | 39.207 | 60.435 | | 53s | 39.207 | 0.716 | 60.077 | 39.565 | KJo is an offsuit hand and 53s is a suited hand. The two hands share no rank, which makes this a pure matchup of card strength, straight chances and flush chances. That is a modest edge, the kind that shows up over many hands and is easy to miss in one. Of every 100 boards, about 0.72 are split pots, and the equity figures already include them. Place 26 of 169 belongs to KJo and place 146 belongs to 53s in the ranking against a random hand. **Boards behind the percentages: 82,190,592 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | KJo | 49,378,000 | 588,000 | 32,224,000 | | 53s | 32,224,000 | 588,000 | 49,378,000 | The total is exact: 48 specific deals times 1,712,304 boards. The three counts are approximate, worked out from the percentages to five decimals and rounded to the nearest thousand. **KJo against 53s read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | KJo | 1.527 | 1.665 | 2.551 | 0.655 | | 53s | 0.655 | 2.551 | 1.665 | 1.527 | The last column is the break-even price: the pot odds a call needs to offer, as a ratio of pot to call. ## Who is ahead on which flops The flop changes the picture. KJo does best on rainbow flops topped by a ten or better, at 68.58%, and worst on low rainbow flops (nine high or lower), at 34.49%.
