## What makes 53s different from similar hands?

53s is 4 combos out of the 1,326 two-card hands and ranks number 146 of the 169 starting-hand classes by equity against a random hand. From the small blind, 53s shoves cleanly 0.5bb deeper than 53o (2bb against 1.5bb). From the big blind, 53s calls cleanly 1bb deeper than 53o (4bb against 3bb). 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 53s 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.
