## When should the big blind call with J9o?

J9o calls every time as the big blind up to 9bb. At 9bb its call is worth -0.8797 big blinds against -1.0000 for folding. At 9bb a call breaks even at 44.4% equity, because the big blind has already posted a full blind that folding gives up. At 9.5bb it mixes, so either choice is close to break-even at that stack. At that stack the call is worth -1.0000 big blinds, level with the -1.0000 for folding. Past 9.5bb the chart folds it.

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.

## 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.
