When should the big blind call with 98o?
98o calls every time as the big blind up to 6bb. At 6bb its call is worth -1.0000 big blinds against -1.0000 for folding. At 6bb a call breaks even at 41.7% equity, because the big blind has already posted a full blind that folding gives up. Past 6bb the chart folds it.

What makes 98o different from similar hands?
98o is 12 combos out of the 1,326 two-card hands and ranks number 99 of the 169 starting-hand classes by equity against a random hand. From the small blind, 98o and 98s both shove at every stack from 1 to 20bb. From the big blind, 98o calls cleanly 2bb shallower than 98s (6bb against 8bb). 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 98o?
The stack pages show the full shove and call charts at each depth, and the hands closest to 98o in strength, along with 98s, have pages of their own. The combos page counts the specific hands that make up 98o and how card removal changes them.
How were the numbers for 98o 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.
