A3o

A3o (ace-three offsuit) wins 55.9% of the time against a single random opponent, which places it 53th out of the 169 starting hands — the top 31.4% of the range. At a six-handed table (five opponents) its equity falls to 16.9% and its rank moves to 84; nine-handed (eight opponents) it holds 10.9% for rank 99. An ace-high hand — watch out for kicker trouble and domination.

Its suited/offsuit twin A3s runs at 58.2% (rank 38), a gap of 2.3 points. Losing the shared suit costs 2.3 points of raw equity. The hand directly above it in the ranking is K8o at 56.0%, and directly below is K5s at 55.7%, so three hands are packed into a band of 0.3 points.

Played heads-up against each of the other 168 hands, A3o is a favourite against 134 of them and an underdog against 34. Its best matchup is K3o at 76.2% and its worst is AA at 7.3% — a spread of 68.9 points, which is why calling A3o simply "strong" or "weak" says very little. 1 opponents land inside one point of a coinflip, the closest being A2s at 50.3%.

A3o dominates 8 hands that share one of its ranks, pushing hardest against K3o at 76.2%. It is dominated by 8 hands in return, the worst of them AKs, which leaves A3o with only 25.3%. A single kicker can move the number by tens of points, and the full table below lists every one of those opponents.

Within the 78 offsuit hands it comes 18 of 78. The strongest hand in that group, AKo, is 9.5 points away, and the weakest, 32o, sits 23.6 points below. Measured against the average equity of all 169 hands, 51%, A3o lands +4.9 points from the middle of the pack, and 52 hands in the full ranking are still ahead of it.

Adding players costs equity steadily: 55.9% against one opponent, 36.1% against two, 21.0% against four and 10.9% against eight. That last figure is 98% of an even nine-way share (11.1%). The Chen formula scores this hand at 5 points, and it arrives 0.9% of the time (12 of 1,326 combinations).

One caveat worth repeating: every number on this page assumes the opponent holds a completely random hand and that the pot goes to showdown. Real opponents hold ranges, and a range that has already put money in is stronger than random — which is exactly why A3o reads as 55.9% here but plays worse than that against a raise. Use the 168 rows in the table below to see which specific holdings are the problem, rather than treating the headline figure as a verdict on the hand.
