Before any board card is dealt, JJ holds 67.72% equity against KTs, which leaves KTs with 32.28%. ## JJ against KTs: the numbers **Exact preflop results for JJ against KTs, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | JJ | 67.514 | 0.405 | 32.081 | 67.717 | | KTs | 32.081 | 0.405 | 67.514 | 32.283 | The first hand is a pocket pair; the second is a suited hand. The pair is ahead of one card and behind the other, so the board decides how that plays out. JJ is well ahead, and KTs needs a specific kind of board to catch up. A split pot comes up on 0.41% of boards, so the wins and the equity differ by half of that. Among the 169 starting hands, JJ is number 4 and KTs is number 22 by strength against a random hand. **Boards behind the percentages: 41,095,296 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | JJ | 27,745,000 | 166,000 | 13,184,000 | | KTs | 13,184,000 | 166,000 | 27,745,000 | 24 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. **JJ against KTs read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | JJ | 2.098 | 1.481 | 3.117 | 0.477 | | KTs | 0.477 | 3.117 | 1.481 | 2.098 | 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 JJ prefers low rainbow flops (nine high or lower), where it holds 81.63%, and likes monotone flops least, where it holds 62.95%.
