K8s

K8s (king-eight suited) wins 58.3% of the time against a single random opponent, which places it 37th out of the 169 starting hands — the top 21.9% of the range. At a six-handed table (five opponents) its equity falls to 21.3% and its rank moves to 39; nine-handed (eight opponents) it holds 15.0% for rank 36. A suited hand — the flush adds a few points of raw equity.

Its suited/offsuit twin K8o runs at 56.0% (rank 52), a gap of 2.3 points. Sharing a suit is worth exactly those 2.3 points here — nothing about the ranks changes. The hand directly above it in the ranking is A7o at 58.7%, and directly below is A3s at 58.2%, so three hands are packed into a band of 0.5 points.

Played heads-up against each of the other 168 hands, K8s is a favourite against 123 of them and an underdog against 45. Its best matchup is 82o at 77.0% and its worst is KK at 11.6% — a spread of 65.4 points, which is why calling K8s simply "strong" or "weak" says very little. 2 opponents land inside one point of a coinflip, the closest being 22 at 49.9%.

K8s dominates 8 hands that share one of its ranks, pushing hardest against 82o at 77.0%. It is dominated by 8 hands in return, the worst of them AKs, which leaves K8s with only 27.7%. 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 17 of 78. The strongest hand in that group, AKs, is 8.9 points away, and the weakest, 32s, sits 22.4 points below. Measured against the average equity of all 169 hands, 51%, K8s lands +7.3 points from the middle of the pack, and 36 hands in the full ranking are still ahead of it.

Adding players costs equity steadily: 58.3% against one opponent, 40.4% against two, 25.0% against four and 15.0% against eight. That last figure is 135% 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 K8s reads as 58.3% 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.
