JJ70.6320.39228.97670.828
QTo28.9760.39270.63229.172

The matchup pits a pocket pair against an offsuit hand. The pair sits between the other hand's two cards: one is higher and one is lower, so the pair is exposed to the higher card.

That is a clear edge, 70.83% to 29.17%, but QTo still wins often enough that one hand proves nothing. A split pot comes up on 0.39% of boards, so the wins and the equity differ by half of that.

Ranked by equity against a random hand, JJ is number 4 of the 169 starting hands and QTo is number 47.
