QJs51.4340.97947.58751.924

We compare a suited hand with a pocket pair. One hand holds a pair and the other holds two cards that both outrank it, which keeps the equity closer than most people expect.

That is a slim edge: neither hand is far ahead. 0.98% of boards are ties, so the equity of each hand is its win rate plus half of that.

For context, QJs sits at number 28 of 169 starting hands and 33 at number 66 when each is run against a random hand.
