What makes J8o different from similar hands?
J8o is 12 combos out of the 1,326 two-card hands and ranks number 79 of the 169 starting-hand classes by equity against a random hand. From the small blind, J8o shoves every time only up to 12bb, while J8s shoves at every stack from 1 to 20bb. From the big blind, J8o calls cleanly 3bb shallower than J8s (7.5bb against 10.5bb).

Where can I check other hands like J8o?

How were the numbers for J8o computed?
Both players hold one of the 169 starting-hand classes, weighted by the pairs of specific hands that share no card, so blockers count. Blinds are 0.5 and 1 with no ante and equal stacks. Each pair of classes is scored with its exact equity over every five-card board, and the solver repeats best responses against the other side's running average until the hands on the edge are made exactly indifferent.
