What makes Q2o different from similar hands?

Q2o is 12 combos out of the 1,326 two-card hands and ranks number 105 of the 169 starting-hand classes by equity against a random hand. From the small blind, Q2o shoves cleanly 5.5bb shallower than Q2s (7bb against 12.5bb). From the big blind, Q2o calls cleanly 1.5bb shallower than Q2s (5.5bb against 7bb). The offsuit version has three times as many combos but gives up the flush equity of its suited twin.

Where can I check other hands like Q2o?

The stack pages show the full shove and call charts at each depth, and the hands closest to Q2o in strength, along with Q2s, have pages of their own. The combos page counts the specific hands that make up Q2o and how card removal changes them.

How were the numbers for Q2o computed?

We solve a chips-only game for two players: small blind 0.5, big blind 1, no ante, equal stacks. Starting hands are the 169 classes, weighted so that shared cards are impossible, and equity comes from counting every five-card board. The solver plays itself with best responses, averages them, and fixes the hands on the edge so they are exactly indifferent.
