What makes Q3s different from similar hands?

Q3s is 4 combos out of the 1,326 two-card hands and ranks number 82 of the 169 starting-hand classes by equity against a random hand. From the small blind, Q3s shoves cleanly 6bb deeper than Q3o (13.5bb against 7.5bb). From the big blind, Q3s calls cleanly 2bb deeper than Q3o (7.5bb against 5.5bb). Suited hands win more often because of flushes, which is why the suited version is the more playable of the pair.

Where can I check other hands like Q3s?

The stack pages show the full shove and call charts at each depth, and the hands closest to Q3s in strength, along with Q3o, have pages of their own. The combos page counts the specific hands that make up Q3s and how card removal changes them.

How were the numbers for Q3s computed?

The game has two players, blinds of 0.5 and 1, no ante and one effective stack. Every one of the 169 starting-hand classes is dealt in proportion to the card-compatible pairs of specific hands, and a showdown is settled with the exact equity from our preflop table. Each side keeps answering the other's average strategy until neither can gain, then the borderline hands are solved exactly.
