A9s

A9s (ace-nine suited) wins 62.8% of the time against a single random opponent, which places it 18th out of the 169 starting hands — the top 10.7% of the range. At a six-handed table (five opponents) its equity falls to 24.3% and its rank moves to 20; nine-handed (eight opponents) it holds 16.8% for rank 19. A suited ace — nut-flush potential on top of top-pair equity.

Its suited/offsuit twin A9o runs at 60.8% (rank 25), a gap of 2 points. Sharing a suit is worth exactly those 2 points here — nothing about the ranks changes. The hand directly above it in the ranking is 66 at 63.3%, and directly below is ATo at 62.6%, so three hands are packed into a band of 0.7 points.

Played heads-up against each of the other 168 hands, A9s is a favourite against 147 of them and an underdog against 21. Its best matchup is 92o at 77.8% and its worst is AA at 11.7% — a spread of 66.1 points, which is why calling A9s simply "strong" or "weak" says very little. 1 opponents land inside one point of a coinflip, the closest being 22 at 49.9%.

A9s dominates 8 hands that share one of its ranks, pushing hardest against 92o at 77.8%. It is dominated by 8 hands in return, the worst of them AKs, which leaves A9s with only 28.8%. 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 suited hands it comes 6 of 78. The strongest hand in that group, AKs, is 4.4 points away, and the weakest, 32s, sits 26.9 points below. Measured against the average equity of all 169 hands, 51%, A9s lands +11.8 points from the middle of the pack, and 17 hands in the full ranking are still ahead of it.

Adding players costs equity steadily: 62.8% against one opponent, 44.5% against two, 28.1% against four and 16.8% against eight. That last figure is 151% of an even nine-way share (11.1%). The Chen formula scores this hand at 7 points, and it arrives 0.3% of the time (4 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 A9s reads as 62.8% 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.
