AQo28.0000.42271.57828.211

One side is a pocket pair, the other is 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.

A lead of 43.58 points is large but not decisive: AQo still takes about 280 of every 1,000 deals. A split pot comes up on 0.42% of boards, so the wins and the equity differ by half of that.

Among the 169 starting hands, KK is number 2 and AQo is number 14 by strength against a random hand.

How this was computed

Each figure is a complete count over boards. Take the 72 specific deals, group them by suit pattern, deal all 1,712,304 boards against each, and compare the two seven-card hands. Equity counts a tie as half a win; the flop rows use every one of a board's ten flops.
