K4s

K4s (king-four suited) wins 54.9% of the time against a single random opponent, which places it 59th out of the 169 starting hands — the top 34.9% of the range. At a six-handed table (five opponents) its equity falls to 19.0% and its rank moves to 54; nine-handed (eight opponents) it holds 13.5% for rank 52. A suited hand — the flush adds a few points of raw equity.

Its suited/offsuit twin K4o runs at 52.2% (rank 75), a gap of 2.7 points. Sharing a suit is worth exactly those 2.7 points here — nothing about the ranks changes. The hand directly above it in the ranking is K7o at 55.3%, and directly below is A2o at 54.9%, so three hands are packed into a band of 0.4 points.

Played heads-up against each of the other 168 hands, K4s is a favourite against 115 of them and an underdog against 53. Its best matchup is Q4o at 75.9% and its worst is KK at 11.6% — a spread of 64.3 points, which is why calling K4s simply "strong" or "weak" says very little. 1 opponents land inside one point of a coinflip, the closest being 22 at 49.0%.

K4s dominates 8 hands that share one of its ranks, pushing hardest against Q4o at 75.9%. It is dominated by 8 hands in return, the worst of them AKs, which leaves K4s with only 26.8%. 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 27 of 78. The strongest hand in that group, AKs, is 12.3 points away, and the weakest, 32s, sits 19 points below. Measured against the average equity of all 169 hands, 51%, K4s lands +3.9 points from the middle of the pack, and 58 hands in the full ranking are still ahead of it.

Adding players costs equity steadily: 54.9% against one opponent, 36.4% against two, 22.3% against four and 13.5% against eight. That last figure is 122% of an even nine-way share (11.1%). The Chen formula scores this hand at 5 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 K4s reads as 54.9% 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.
