What makes Q8o different from similar hands?

Q8o is 12 combos out of the 1,326 two-card hands and ranks number 68 of the 169 starting-hand classes by equity against a random hand. From the small blind, Q8o shoves every time only up to 13bb, while Q8s shoves at every stack from 1 to 20bb. From the big blind, Q8o calls cleanly 3.5bb shallower than Q8s (9.5bb against 13bb). 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 Q8o?

The stack pages show the full shove and call charts at each depth, and the hands closest to Q8o in strength, along with Q8s, have pages of their own. The combos page counts the specific hands that make up Q8o and how card removal changes them.

How were the numbers for Q8o 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.
