K2s

K2s (king-deuce suited) wins 53.2% of the time against a single random opponent, which places it 69th out of the 169 starting hands — the top 40.8% of the range. At a six-handed table (five opponents) its equity falls to 18.5% and its rank moves to 64; nine-handed (eight opponents) it holds 13.1% for rank 59. A suited hand — the flush adds a few points of raw equity.

Its suited/offsuit twin K2o runs at 50.4% (rank 86), a gap of 2.8 points. Sharing a suit is worth exactly those 2.8 points here — nothing about the ranks changes. The hand directly above it in the ranking is Q6s at 53.6%, and directly below is J9o at 53.2%, so three hands are packed into a band of 0.4 points.

Played heads-up against each of the other 168 hands, K2s is a favourite against 111 of them and an underdog against 57. Its best matchup is Q2o at 76.3% and its worst is KK at 10.7% — a spread of 65.6 points, which is why calling K2s simply "strong" or "weak" says very little. 2 opponents land inside one point of a coinflip, the closest being K3o at 49.6%.

K2s dominates 8 hands that share one of its ranks, pushing hardest against Q2o at 76.3%. It is dominated by 8 hands in return, the worst of them AKs, which leaves K2s with only 25.9%. 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 33 of 78. The strongest hand in that group, AKs, is 14 points away, and the weakest, 32s, sits 17.3 points below. Measured against the average equity of all 169 hands, 51%, K2s lands +2.2 points from the middle of the pack, and 68 hands in the full ranking are still ahead of it.

Adding players costs equity steadily: 53.2% against one opponent, 34.8% against two, 21.0% against four and 13.1% against eight. That last figure is 118% 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 K2s reads as 53.2% 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.

K2s 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. For flushes, two or more of its suit land on the flop 11.8% of the time (a made flush 0.842%), and a flush is complete by the river 6.40%.

Put together, K2s flops a pair or better or a strong draw (a flush draw or an eight-out straight draw) 43.1% of the time — rank 76 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, K2s goes from 53.2% before the flop up to 70.7% when either card pairs, and down to 44.8% 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 49.5%; missing with nothing above K leaves 43.2%.

By board shape: rainbow 52.6%, two-tone 53.8%, monotone 51.8%. Two of your suit (a flush draw) gives 64.8% (10.9% of flops), and three of your suit (a made flush) 96.8% (0.842%). A paired board gives 56.6%, and a connected board (three ranks within five) 47.3%. The best row in the table is "Three of your suit (made flush)" at 96.8%, the worst "and nothing above K" at 43.2%.

The 53.2% 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 53.21% (a gap of 0.01 points). Each equity is taken with the flop out and the turn and river still to come.
