Here an offsuit hand (AKo) meets a suited hand (A6s). 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.

AKo is well ahead, and A6s needs a specific kind of board to catch up. The tie share is 4.15%: on those boards the pot is chopped and neither hand wins outright.

Ranked by equity against a random hand, AKo is number 12 of the 169 starting hands and A6s is number 31.
