KJs

KJs (king-jack suited) wins 62.5% of the time against a single random opponent, which places it 20th out of the 169 starting hands — the top 11.8% of the range. At a six-handed table (five opponents) its equity falls to 27.1% and its rank moves to 11; nine-handed (eight opponents) it holds 19.0% for rank 11. A suited hand — the flush adds a few points of raw equity.

Its suited/offsuit twin KJo runs at 60.5% (rank 26), a gap of 2 points. Sharing a suit is worth exactly those 2 points here — nothing about the ranks changes. The hand directly above it in the ranking is ATo at 62.6%, and directly below is A8s at 61.9%, so three hands are packed into a band of 0.7 points.

Played heads-up against each of the other 168 hands, KJs is a favourite against 132 of them and an underdog against 36. Its best matchup is J2o at 77.7% and its worst is KK at 14.1% — a spread of 63.6 points, which is why calling KJs simply "strong" or "weak" says very little. 4 opponents land inside one point of a coinflip, the closest being 55 at 49.6%.

KJs dominates 8 hands that share one of its ranks, pushing hardest against J2o at 77.7%. It is dominated by 6 hands in return, the worst of them AJs, which leaves KJs with only 28.8%. 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 7 of 78. The strongest hand in that group, AKs, is 4.7 points away, and the weakest, 32s, sits 26.6 points below. Measured against the average equity of all 169 hands, 51%, KJs lands +11.5 points from the middle of the pack, and 19 hands in the full ranking are still ahead of it.

Adding players costs equity steadily: 62.5% against one opponent, 46.1% against two, 30.9% against four and 19.0% against eight. That last figure is 171% of an even nine-way share (11.1%). The Chen formula scores this hand at 9 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 KJs reads as 62.5% 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.

KJs 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) 25.1%. By the river it has made a pair or better 48.7% of the time.

For straights, the flop completes one 0.653% of the time (128 flops), gives an eight-out draw 3.67% and a four-out gutshot 12.7%. By the river a straight using a hole card completes 5.20% 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, KJs flops a pair or better or a strong draw (a flush draw or an eight-out straight draw) 45.8% of the time — rank 27 of the 156 unpaired hands (tied with 1 other). The highest is JTs, T9s, 98s and 4 others at 50.6% and the lowest AKo, A2o at 32.8%.

Against one random hand, KJs goes from 62.6% before the flop up to 82.1% when either card pairs, and down to 53.2% 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 57.5%; missing with nothing above K leaves 51.7%.

By board shape: rainbow 62.4%, two-tone 63.0%, monotone 59.3%. Two of your suit (a flush draw) gives 71.3% (10.9% of flops), and three of your suit (a made flush) 96.9% (0.842%). A paired board gives 62.8%, and a connected board (three ranks within five) 57.1%. The best row in the table is "Three of your suit (made flush)" at 96.9%, the worst "and nothing above K" at 51.7%.

The 62.5% 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 62.57% (a gap of 0.07 points). Each equity is taken with the flop out and the turn and river still to come.
