A4s

A4s (ace-four suited) wins 59.0% of the time against a single random opponent, which places it 35th out of the 169 starting hands — the top 20.7% of the range. At a six-handed table (five opponents) its equity falls to 21.9% and its rank moves to 35; nine-handed (eight opponents) it holds 15.7% for rank 30. A suited ace — nut-flush potential on top of top-pair equity.

Its suited/offsuit twin A4o runs at 56.8% (rank 50), a gap of 2.2 points. Sharing a suit is worth exactly those 2.2 points here — nothing about the ranks changes. The hand directly above it in the ranking is QTs at 59.5%, and directly below is A7o at 58.7%, so three hands are packed into a band of 0.8 points.

Played heads-up against each of the other 168 hands, A4s is a favourite against 137 of them and an underdog against 31. Its best matchup is K4o at 76.9% and its worst is AA at 12.8% — a spread of 64.1 points, which is why calling A4s simply "strong" or "weak" says very little. 1 opponents land inside one point of a coinflip, the closest being 22 at 49.9%.

A4s dominates 8 hands that share one of its ranks, pushing hardest against K4o at 76.9%. It is dominated by 8 hands in return, the worst of them AKs, which leaves A4s with only 29.7%. 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 16 of 78. The strongest hand in that group, AKs, is 8.2 points away, and the weakest, 32s, sits 23.1 points below. Measured against the average equity of all 169 hands, 51%, A4s lands +8 points from the middle of the pack, and 34 hands in the full ranking are still ahead of it.

Adding players costs equity steadily: 59.0% against one opponent, 40.7% against two, 25.3% against four and 15.7% against eight. That last figure is 141% 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 A4s reads as 59.0% 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.
