Over all 1,712,304 boards that can follow this deal, QQ finishes with 85.54% of the pot and Q9s with 14.46%. ## QQ against Q9s: the numbers **Exact preflop results for QQ against Q9s, in percent** | Hand | Wins | Ties | Loses | Equity | | --- | --- | --- | --- | --- | | QQ | 84.702 | 1.673 | 13.625 | 85.539 | | Q9s | 13.625 | 1.673 | 84.702 | 14.461 | One side is a pocket pair, the other is a suited hand. One hand holds a card of the same rank as the pair, which removes a card the pair needs and makes the pair a bigger favorite. QQ is a big favorite here before anyone sees a flop. The tie share is 1.67%: on those boards the pot is chopped and neither hand wins outright. Place 3 of 169 belongs to QQ and place 43 belongs to Q9s in the ranking against a random hand. **Boards behind the percentages: 20,547,648 counted in all** | Hand | Boards won, about | Boards tied, about | Boards lost, about | | --- | --- | --- | --- | | QQ | 17,404,000 | 344,000 | 2,800,000 | | Q9s | 2,800,000 | 344,000 | 17,404,000 | The total is exact: 12 specific deals times 1,712,304 boards.

A shared suit is impossible for this matchup, so QQ's 85.54% is the answer for every suit pattern. **QQ against Q9s by suit overlap, in percent** | Deals | Specific deals | Share of deals | QQ wins | Ties | Q9s wins | QQ equity | | --- | --- | --- | --- | --- | --- | --- | | Share a suit | 0 | 0.00 | not possible | not possible | not possible | not possible | | No shared suit | 12 | 100.00 | 84.702 | 1.673 | 13.625 | 85.539 | ## How often this matchup comes up This page stands for 12 specific-card matchups (0.0007% of 1,624,350 ordered deals), or 24 once you count the seats both ways (0.0015%). ## A worked example Take a $200 pot built from $100 each.
