What makes 65o different from similar hands?
65o is 12 combos out of the 1,326 two-card hands and ranks number 145 of the 169 starting-hand classes by equity against a random hand. From the small blind, 65o shoves every time only up to 2bb, while 65s shoves at every stack from 1 to 20bb. From the big blind, 65o calls cleanly 1bb shallower than 65s (3.5bb against 4.5bb). 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 65o?
The stack pages show the full shove and call charts at each depth, and the hands closest to 65o in strength, along with 65s, have pages of their own. The combos page counts the specific hands that make up 65o and how card removal changes them.
How were the numbers for 65o 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.
