One side is an offsuit hand, the other is a suited hand. With no overlap in ranks, every card that pairs one hand is a card that does not pair the other.

That is a modest edge, the kind that shows up over many hands and is easy to miss in one. Ties are 0.68% of the outcomes here; each tied board gives both hands half the pot.

KQo ranks number 23 of 169 starting hands, and 75s ranks number 124, by equity against a random hand.
