Q3o: the 12 combos

An offsuit hand pairs any queen with any three of a different suit: 4 x 4 = 16 pairings, minus the 4 suited ones, leaves 12.

Here is every one of the 12 combos, written as the two cards you would see. Clubs, diamonds, hearts and spades each appear in the way the count above requires.

How cards you can see change the count

Seeing a card changes which hands are possible. Here is the count of Q3o combos that remain after you hold, or the board shows, one card of each rank.

Holding a queen or a three takes Q3o from 12 combos down to 9, a cut of 25%. Any card of a different rank leaves all 12 combos in play.

When the board is paired

A paired board shows two cards of one rank, and those two cards cannot be in an opponent's hand either. The table shows the Q3o combos left when the board holds a pair of each rank.

A worked example

You hold a queen and a two. Your opponent's hand is one of 1,225 equally likely two-card holdings. 9 of them are Q3o, which is 0.73%, or about 1 in 136. If your two cards had nothing to do with Q3o, the same hand would have 12 combos and a 0.98% chance, about 1 in 102.

How strong is Q3o?

Measured against a random hand, Q3o has 48.22% equity and the number 98 spot of 169, in the middle of the ranking. Wins count once and ties count half.

Together with all stronger classes, Q3o covers 722 combos, which is 54.45% of the 1,326 starting hands.

Q3o against ranges of hands

Against a range, equity is averaged over every hand in it, weighted by how many combos of each hand are still possible. Q3o makes 23.62% against the top 5 percent (60 combos), 27.76% against the top 10 percent (130 combos), 30.07% against the top 20 percent (264 combos), 31.47% against the top 30 percent (386 combos) and 35.99% against the top 50 percent (658 combos).

Top 20 percent26430.07%
Top 30 percent38631.47%
Top 50 percent65835.99%

Q3o is behind all five of these ranges, even the top 50 percent, so it is the underdog on average against each of them.

Your own cards block part of an opponent's strong range. The top 10 percent holds 130 combos, and when you hold a combo of Q3o an average of 122.00 of them stay possible. That is 8.00 combos fewer than the 130 an opponent has before you look.

How this was computed

The count starts from 1,326 two-card hands sorted into 169 classes. Removing the combos that use known cards gives each blocker and board-pair row, with nothing estimated.

Our preflop table counts every board (1,712,304 of them) for each pair of classes, so rank and equity here are exact. Ties are halves; ranges are weighted by live combos.
