What makes J6s different from similar hands?
J6s is 4 combos out of the 1,326 two-card hands and ranks number 85 of the 169 starting-hand classes by equity against a random hand. From the small blind, J6s shoves cleanly 11bb deeper than J6o (17.5bb against 6.5bb). From the big blind, J6s calls cleanly 2bb deeper than J6o (7bb against 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 J6s?
The stack pages show the full shove and call charts at each depth, and the hands closest to J6s in strength, along with J6o, have pages of their own. The combos page counts the specific hands that make up J6s and how card removal changes them.
How were the numbers for J6s 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.
