AKs meets KTs, and both are suited hands. Because the hands share one rank, the one with the higher kicker is ahead when that rank pairs and the other hand is mostly drawing.

That is a clear edge, 70.89% to 29.11%, but KTs still wins often enough that one hand proves nothing. 1.14% of boards are ties, so the equity of each hand is its win rate plus half of that.

Among the 169 starting hands, AKs is number 8 and KTs is number 22 by strength against a random hand.
