## What makes T4s different from similar hands?

T4s is 4 combos out of the 1,326 two-card hands and ranks number 108 of the 169 starting-hand classes by equity against a random hand. From the small blind, T4s shoves cleanly 7bb deeper than T4o (10.5bb against 3.5bb). From the big blind, T4s calls cleanly 1.5bb deeper than T4o (5bb against 3.5bb). 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 T4s 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.
