Each row is a suit-isomorphism class: relabeling the four suits doesn't change equity, so every combo in a row has the identical, exactly-enumerated number. “Combos” counts the hand-vs-hand combinations the row represents.
Why QQ is in so much trouble
Both players hold a made pair, but only one of them is winning unimproved, and pocket pairs rarely improve. QQ has exactly two set cards left in the deck, seen on the board just 19.9% of the time, and even a queen doesn't guarantee the pot on straight- or flush-heavy runouts. Meanwhile AA needs nothing: it can check-snooze to the river and still win most showdowns. That asymmetry is the whole story of pair-over-pair "coolers".
- QQ's main lifeline is one of the two remaining queens, and at least one lands on the board only 19.9% of the time. The rest of its 18.5% comes from straights, flushes and runout quirks.
- Suits shift the matchup by 1.4 points: QQ does best with no shared suits (19.1%, with two live flush suits) and worst when both suits are shared (17.8%, because every flush it makes loses to a bigger one).
- The rank of the underpair barely matters against aces: QQ wins 18.5% here, and KK does only slightly better at 18.1%.
How it was calculated
