J8o

J8o (jack-eight offsuit) wins 51.6% of the time against a single random opponent, which places it 78th out of the 169 starting hands — the top 46.2% of the range. At a six-handed table (five opponents) its equity falls to 16.5% and its rank moves to 91; nine-handed (eight opponents) it holds 10.6% for rank 106. Two unconnected offsuit cards — the class of hand most often overvalued.

Its suited/offsuit twin J8s runs at 54.0% (rank 64), a gap of 2.4 points. Losing the shared suit costs 2.4 points of raw equity. The hand directly above it in the ranking is Q4s at 51.8%, and directly below is T9o at 51.4%, so three hands are packed into a band of 0.4 points.

Played heads-up against each of the other 168 hands, J8o is a favourite against 84 of them and an underdog against 84. Its best matchup is 83o at 75.4% and its worst is JJ at 9.7% — a spread of 65.7 points, which is why calling J8o simply "strong" or "weak" says very little. 2 opponents land inside one point of a coinflip, the closest being 22 at 49.5%.

J8o dominates 8 hands that share one of its ranks, pushing hardest against 83o at 75.4%. It is dominated by 8 hands in return, the worst of them KJs, which leaves J8o with only 24.6%. 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 29 of 78. The strongest hand in that group, AKo, is 13.8 points away, and the weakest, 32o, sits 19.3 points below. Measured against the average equity of all 169 hands, 51%, J8o lands +0.6 points from the middle of the pack, and 77 hands in the full ranking are still ahead of it.

Adding players costs equity steadily: 51.6% against one opponent, 34.3% against two, 20.2% against four and 10.6% against eight. That last figure is 95% of an even nine-way share (11.1%). The Chen formula scores this hand at 4 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 J8o reads as 51.6% 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.

J8o 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) 15.3%. 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 4.65% and a four-out gutshot 13.4%. By the river a straight using a hole card completes 6.00% of the time.

Put together, J8o flops a pair or better or a strong draw (an eight-out straight draw) 37.2% of the time — rank 99 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, J8o goes from 51.5% before the flop up to 74.4% when either card pairs, and down to 40.5% when both miss. It connects 32.4% of the time (6,356 of 19,600 flops). Missing with a card above J on board leaves 41.3%; missing with nothing above J leaves 39.2%.

By board shape: rainbow 51.7%, two-tone 51.3%, monotone 51.9%. A monotone flop in one of your suits gives 60.9%. A paired board gives 50.1%, and a connected board (three ranks within five) 52.5%. The best row in the table is "Either card hits (a matching rank on the flop)" at 74.4%, the worst "and nothing above J" at 39.2%.

The 51.6% 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 51.49% (a gap of 0.11 points). Each equity is taken with the flop out and the turn and river still to come.
