K8o

K8o (king-eight offsuit) wins 56.0% of the time against a single random opponent, which places it 52th out of the 169 starting hands — the top 30.8% of the range. At a six-handed table (five opponents) its equity falls to 17.2% and its rank moves to 78; nine-handed (eight opponents) it holds 10.7% for rank 103. Two unconnected offsuit cards — the class of hand most often overvalued.

Its suited/offsuit twin K8s runs at 58.3% (rank 37), a gap of 2.3 points. Losing the shared suit costs 2.3 points of raw equity. The hand directly above it in the ranking is Q8s at 56.0%, and directly below is A3o at 55.9%, so three hands are packed into a band of 0.1 points.

Played heads-up against each of the other 168 hands, K8o is a favourite against 122 of them and an underdog against 46. Its best matchup is 82o at 76.0% and its worst is KK at 6.2% — a spread of 69.8 points, which is why calling K8o simply "strong" or "weak" says very little.

K8o dominates 8 hands that share one of its ranks, pushing hardest against 82o at 76.0%. It is dominated by 8 hands in return, the worst of them AKs, which leaves K8o with only 23.2%. 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 offsuit hands it comes 17 of 78. The strongest hand in that group, AKo, is 9.4 points away, and the weakest, 32o, sits 23.7 points below. Measured against the average equity of all 169 hands, 51%, K8o lands +5 points from the middle of the pack, and 51 hands in the full ranking are still ahead of it.

Adding players costs equity steadily: 56.0% against one opponent, 36.9% against two, 21.4% against four and 10.7% against eight. That last figure is 96% of an even nine-way share (11.1%). The Chen formula scores this hand at 3 points, and it arrives 0.9% of the time (12 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 K8o reads as 56.0% 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.

K8o pairs the board on the flop — at least one of its two ranks hits — 32.4% of the time, and flops top pair or better (the paired card is the highest on the board, or two pair and up) 19.6%. By the river it has made a pair or better 48.7% of the time.

For straights, the flop completes one 0.0000% of the time (zero flops — the two cards are too far apart), gives an eight-out draw 1.63% and a four-out gutshot 4.57%. By the river a straight using a hole card completes 2.48% of the time.

Put together, K8o flops a pair or better or a strong draw (an eight-out straight draw) 34.1% of the time — rank 129 of the 156 unpaired hands (tied with 13 others). The highest is JTs, T9s, 98s and 4 others at 50.6% and the lowest AKo, A2o at 32.8%.

Against one random hand, K8o goes from 56.0% before the flop up to 76.8% when either card pairs, and down to 46.0% when both miss. It connects 32.4% of the time (6,356 of 19,600 flops). Missing with a card above K on board leaves 49.0%; missing with nothing above K leaves 45.0%.

By board shape: rainbow 56.5%, two-tone 55.7%, monotone 55.3%. A monotone flop in one of your suits gives 64.7%. A paired board gives 57.6%, and a connected board (three ranks within five) 54.0%. The best row in the table is "Either card hits (a matching rank on the flop)" at 76.8%, the worst "and nothing above K" at 45.0%.

The 56.0% at the top of the page is a 400,000-hand simulation; this table counts every deal of the opponent's two cards and the five-card board (2,097,572,400 per starting hand), which puts the pre-flop figure at 56.02% (a gap of 0.02 points). Each equity is taken with the flop out and the turn and river still to come.
