KK84.7511.16714.08285.335
KTs14.0821.16784.75114.665

We compare a pocket pair with a suited hand. The non-pair hand shares a rank with the pair, so two of its outs for pairing are blocked by the pair itself.

That is a heavy lead: KTs needs the board to help it on most runouts and still falls behind far more often than not. 1.17% 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, KK is number 2 of the 169 starting hands and KTs is number 22.
