# QQ vs K9o: preflop equity

QQ is a big favorite over K9o before the flop: 71.79% to 28.21% equity, counted exactly over every board, with the split by flop type and suit.

The exact count puts QQ at 71.79% and K9o at 28.21% when the two hands see all five board cards.

## QQ against K9o: the numbers

**Exact preflop results for QQ against K9o, in percent**

| Hand | Wins | Ties | Loses | Equity |
| --- | --- | --- | --- | --- |
| QQ | 71.594 | 0.388 | 28.018 | 71.788 |
| K9o | 28.018 | 0.388 | 71.594 | 28.212 |

The first hand is a pocket pair; the second is an offsuit hand. One of the other hand's cards outranks the pair and one is below it, which makes this a closer race than a pair against two small cards.

QQ is well ahead, and K9o needs a specific kind of board to catch up. Of every 100 boards, about 0.39 are split pots, and the equity figures already include them.

In the ranking of all 169 starting hands, QQ is number 3 and K9o is number 40.

**Boards behind the percentages: 123,285,888 counted in all**

| K9o | 34,542,000 | 478,000 | 88,265,000 |

72 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.
