AJo66.3851.76531.85067.267
JTs31.8501.76566.38532.733

The first hand is an offsuit hand; the second is a suited hand. 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 34.54 points is large but not decisive: JTs still takes about 318 of every 1,000 deals. A split pot comes up on 1.77% of boards, so the wins and the equity differ by half of that.

Among the 169 starting hands, AJo is number 15 and JTs is number 45 by strength against a random hand.
