What makes J9o different from similar hands?
J9o is 12 combos out of the 1,326 two-card hands and ranks number 70 of the 169 starting-hand classes by equity against a random hand. From the small blind, J9o and J9s both shove at every stack from 1 to 20bb. From the big blind, J9o calls cleanly 4bb shallower than J9s (9bb 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 J9o?
The stack pages show the full shove and call charts at each depth, and the hands closest to J9o in strength, along with J9s, have pages of their own. The combos page counts the specific hands that make up J9o and how card removal changes them.
How were the numbers for J9o 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.
