Q2o: the 12 combos

Count every queen and two pairing (16) and take away the suited ones (4): 12 combos are offsuit.

These are the 12 specific hands that count as Q2o. Each tile is one two-card holding, and no two tiles are the same hand.

How cards you can see change the count

This is the blocker table for Q2o. One visible card of a given rank removes the combos that need it, and the rest stay possible.

With a queen or a two in view, 9 of the 12 combos of Q2o remain, which removes 25%. Any card of a different rank leaves all 12 combos in play.

When the board is paired

Boards with a pair remove two cards of one rank at once. The rows give the Q2o combos left for each paired rank.

A worked example

Suppose you look down at a queen and a three. Any opponent hand comes from 1,225 possibilities. Q2o makes up 9 of them, which is 0.73% (1 in 136); if you held neither card's rank in common with Q2o, it would be 12 of them, 0.98%.

How strong is Q2o?

Order all 169 classes by equity against a random hand and Q2o lands at number 105, below the middle of the ranking, with 47.30%. A tie is worth half a win in that figure.

Down to and including Q2o, the ranking holds 782 combos, or 58.97% of deals; 770 of them belong to hands above it.
