K2o

K2o (king-deuce offsuit) wins 50.4% of the time against a single random opponent, which places it 86th out of the 169 starting hands — the top 50.9% of the range. At a six-handed table (five opponents) its equity falls to 13.7% and its rank moves to 127; nine-handed (eight opponents) it holds 8.8% for rank 133. Two unconnected offsuit cards — the class of hand most often overvalued.

Its suited/offsuit twin K2s runs at 53.2% (rank 69), a gap of 2.8 points. Losing the shared suit costs 2.8 points of raw equity. The hand directly above it in the ranking is J6s at 50.5%, and directly below is Q5o at 50.2%, so three hands are packed into a band of 0.3 points.

Played heads-up against each of the other 168 hands, K2o is a favourite against 110 of them and an underdog against 58. Its best matchup is Q2o at 75.4% and its worst is KK at 5.4% — a spread of 70 points, which is why calling K2o simply "strong" or "weak" says very little. 2 opponents land inside one point of a coinflip, the closest being JTs at 50.8%.

K2o dominates 8 hands that share one of its ranks, pushing hardest against Q2o at 75.4%. It is dominated by 8 hands in return, the worst of them AKs, which leaves K2o with only 21.6%. 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 33 of 78. The strongest hand in that group, AKo, is 15 points away, and the weakest, 32o, sits 18.1 points below. Measured against the average equity of all 169 hands, 51%, K2o lands -0.6 points from the middle of the pack, and 85 hands in the full ranking are still ahead of it.

Adding players costs equity steadily: 50.4% against one opponent, 31.3% against two, 17.2% against four and 8.8% against eight. That last figure is 79% 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 K2o reads as 50.4% 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.

K2o 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) 15.4%. 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 0.653% and a four-out gutshot 3.92%. By the river a straight using a hole card completes 1.69% of the time.

Put together, K2o flops a pair or better or a strong draw (an eight-out straight draw) 33.1% of the time — rank 154 of the 156 unpaired hands. The highest is JTs, T9s, 98s and 4 others at 50.6% and the lowest AKo, A2o at 32.8%.

Against one random hand, K2o goes from 50.5% before the flop up to 70.2% when either card pairs, and down to 41.0% 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 46.0%; missing with nothing above K leaves 39.4%.

By board shape: rainbow 51.1%, two-tone 50.2%, monotone 49.6%. A monotone flop in one of your suits gives 57.8%. A paired board gives 54.4%, and a connected board (three ranks within five) 43.9%. The best row in the table is "Either card hits (a matching rank on the flop)" at 70.2%, the worst "and nothing above K" at 39.4%.

The 50.4% 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 50.51% (a gap of 0.11 points). Each equity is taken with the flop out and the turn and river still to come.
