## What makes J2s different from similar hands?

J2s is 4 combos out of the 1,326 two-card hands and ranks number 104 of the 169 starting-hand classes by equity against a random hand. From the small blind, J2s shoves cleanly 4bb deeper than J2o (8.5bb against 4.5bb). From the big blind, J2s calls cleanly 1.5bb deeper than J2o (5.5bb against 4bb). Suited hands win more often because of flushes, which is why the suited version is the more playable of the pair.

## How were the numbers for J2s computed?

The game has two players, blinds of 0.5 and 1, no ante and one effective stack. Every one of the 169 starting-hand classes is dealt in proportion to the card-compatible pairs of specific hands, and a showdown is settled with the exact equity from our preflop table. Each side keeps answering the other's average strategy until neither can gain, then the borderline hands are solved exactly.
