We compare a suited hand with a pocket pair. A pair against two higher cards is the classic race: the pair is usually a small favorite or close to even, and each overcard that pairs is a way to take the lead.

That is a slim edge: neither hand is far ahead. 0.65% of boards are ties, so the equity of each hand is its win rate plus half of that.

Ranked by equity against a random hand, A6s is number 31 of the 169 starting hands and 22 is number 87.
