Before any board card is dealt, QTs holds 69.21% equity against T9s, which leaves T9s with 30.79%. ## QTs against T9s: the numbers **Exact preflop results for QTs against T9s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | QTs | 67.235 | 3.952 | 28.813 | 69.211 | | T9s | 28.813 | 3.952 | 67.235 | 30.789 | Here suited hands face each other, QTs on one side and T9s on the other. Because the hands share one rank, the one with the higher kicker is ahead when that rank pairs and the other hand is mostly drawing. QTs is well ahead, and T9s needs a specific kind of board to catch up. A split pot comes up on 3.95% of boards, so the wins and the equity differ by half of that. The hand ranking puts QTs at 34 and T9s at 64 out of 169 starting hands. **Boards behind the percentages: 20,547,648 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | QTs | 13,815,000 | 812,000 | 5,920,000 | | T9s | 5,920,000 | 812,000 | 13,815,000 | Exact total: 12 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. **QTs against T9s read as odds** | Hand | Equity as odds (to 1) | Wins one deal in | Loses one deal in | Pot odds needed to call (to 1) | | --- | --- | --- | --- | --- | | QTs | 2.248 | 1.487 | 3.471 | 0.445 | | T9s | 0.445 | 3.471 | 1.487 | 2.248 | 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 Split by what the flop looks like, QTs peaks at 74.13% on rainbow flops topped by a ten or better and bottoms out at 58.80% on low rainbow flops (nine high or lower).
