K5s

K5s (king-five suited) wins 55.7% of the time against a single random opponent, which places it 54th out of the 169 starting hands — the top 32% of the range. At a six-handed table (five opponents) its equity falls to 19.8% and its rank moves to 50; nine-handed (eight opponents) it holds 14.0% for rank 48. A suited hand — the flush adds a few points of raw equity.

Its suited/offsuit twin K5o runs at 53.2% (rank 71), a gap of 2.5 points. Sharing a suit is worth exactly those 2.5 points here — nothing about the ranks changes. The hand directly above it in the ranking is A3o at 55.9%, and directly below is J9s at 55.7%, so three hands are packed into a band of 0.2 points.

Played heads-up against each of the other 168 hands, K5s is a favourite against 117 of them and an underdog against 51. Its best matchup is Q5o at 75.7% and its worst is KK at 12.0% — a spread of 63.7 points, which is why calling K5s simply "strong" or "weak" says very little. 1 opponents land inside one point of a coinflip, the closest being 22 at 49.5%.

K5s dominates 8 hands that share one of its ranks, pushing hardest against Q5o at 75.7%. It is dominated by 8 hands in return, the worst of them AKs, which leaves K5s with only 27.4%. 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 25 of 78. The strongest hand in that group, AKs, is 11.5 points away, and the weakest, 32s, sits 19.8 points below. Measured against the average equity of all 169 hands, 51%, K5s lands +4.7 points from the middle of the pack, and 53 hands in the full ranking are still ahead of it.

Adding players costs equity steadily: 55.7% against one opponent, 37.3% against two, 23.0% against four and 14.0% against eight. That last figure is 126% 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 K5s reads as 55.7% 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.
