Counting every board, the equity split is 62.97% for KJs and 37.03% for 53s, so KJs leads by 25.94 points. ## KJs against 53s: the numbers **Exact preflop results for KJs against 53s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | KJs | 62.591 | 0.749 | 36.660 | 62.965 | | 53s | 36.660 | 0.749 | 62.591 | 37.035 | Each side holds one of the suited hands: KJs and 53s. With no overlap in ranks, every card that pairs one hand is a card that does not pair the other. That is a modest edge, the kind that shows up over many hands and is easy to miss in one. Ties are part of the picture: 0.75% of boards end in a split pot, and each side counts that as half a win. Among the 169 starting hands, KJs is number 20 and 53s is number 146 by strength against a random hand. **Boards behind the percentages: 27,396,864 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | KJs | 17,148,000 | 205,000 | 10,044,000 | | 53s | 10,044,000 | 205,000 | 17,148,000 | 16 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. **KJs 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) | | --- | --- | --- | --- | --- | | KJs | 1.700 | 1.598 | 2.728 | 0.588 | | 53s | 0.588 | 2.728 | 1.598 | 1.700 | 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 Break the boards down by their first three cards and KJs is strongest on rainbow flops topped by a ten or better (69.88%) and weakest on low rainbow flops (nine high or lower) (37.00%).
