What makes 72s different from similar hands?
72s is 4 combos out of the 1,326 two-card hands and ranks number 152 of the 169 starting-hand classes by equity against a random hand. From the small blind, 72s shoves cleanly 0.5bb deeper than 72o (2bb against 1.5bb). From the big blind, 72s calls cleanly 0.5bb deeper than 72o (3bb against 2.5bb). 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 72s?
The stack pages show the full shove and call charts at each depth, and the hands closest to 72s in strength, along with 72o, have pages of their own. The combos page counts the specific hands that make up 72s and how card removal changes them.
How were the numbers for 72s 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.
