What makes 43o different from similar hands?
43o is 12 combos out of the 1,326 two-card hands and ranks number 164 of the 169 starting-hand classes by equity against a random hand. From the small blind, 43o shoves cleanly 0.5bb shallower than 43s (1.5bb against 2bb). From the big blind, 43o calls cleanly 0.5bb shallower than 43s (3bb against 3.5bb). 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 43o?
The stack pages show the full shove and call charts at each depth, and the hands closest to 43o in strength, along with 43s, have pages of their own. The combos page counts the specific hands that make up 43o and how card removal changes them.
How were the numbers for 43o computed?
We solve a chips-only game for two players: small blind 0.5, big blind 1, no ante, equal stacks. Starting hands are the 169 classes, weighted so that shared cards are impossible, and equity comes from counting every five-card board. The solver plays itself with best responses, averages them, and fixes the hands on the edge so they are exactly indifferent.
