88 vs ATo: preflop equity

88 against ATo: the numbers

88, a pocket pair, plays ATo, an offsuit hand. One hand holds a pair and the other holds two cards that both outrank it, which keeps the equity closer than most people expect.

The lead is steady rather than large, and the flop still has plenty of say in who wins. A split pot comes up on 0.36% of boards, so the wins and the equity differ by half of that.

72 specific deals times 1,712,304 boards gives the exact total. The won, tied and lost counts are approximations from the five-decimal percentages, rounded to the nearest thousand.

The last column is the smallest pot odds, written as a pot-to-call ratio, at which a call breaks even with this equity.
