Each side holds one of the suited hands: KQs and KJs. Sharing a rank is the signature of a dominated hand, since the weaker hand is usually out-kicked when the shared rank shows up.

A lead of 41.70 points is large but not decisive: KJs still takes about 266 of every 1,000 deals. The tie share is 5.15%: on those boards the pot is chopped and neither hand wins outright.
