What makes 65s different from similar hands?
65s is 4 combos out of the 1,326 two-card hands and ranks number 128 of the 169 starting-hand classes by equity against a random hand. From the small blind, 65s shoves at every stack from 1 to 20bb, while 65o shoves every time only up to 2bb. From the big blind, 65s calls cleanly 1bb deeper than 65o (4.5bb against 3.5bb). 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 65s?
The stack pages show the full shove and call charts at each depth, and the hands closest to 65s in strength, along with 65o, have pages of their own. The combos page counts the specific hands that make up 65s and how card removal changes them.
How were the numbers for 65s 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.
