J4o

J4o (jack-four offsuit) wins 46.1% of the time against a single random opponent, which places it 111th out of the 169 starting hands — the top 65.7% of the range. At a six-handed table (five opponents) its equity falls to 12.3% and its rank moves to 144; nine-handed (eight opponents) it holds 7.6% for rank 147. Two unconnected offsuit cards — the class of hand most often overvalued.

Its suited/offsuit twin J4s runs at 49.2% (rank 93), a gap of 3.1 points. Losing the shared suit costs 3.1 points of raw equity. The hand directly above it in the ranking is 86s at 46.3%, and directly below is T6o at 46.0%, so three hands are packed into a band of 0.3 points.

Played heads-up against each of the other 168 hands, J4o is a favourite against 76 of them and an underdog against 92. Its best matchup is T4o at 73.8% and its worst is JJ at 6.8% — a spread of 67 points, which is why calling J4o simply "strong" or "weak" says very little. 2 opponents land inside one point of a coinflip, the closest being J3s at 50.3%.

J4o dominates 8 hands that share one of its ranks, pushing hardest against T4o at 73.8%. It is dominated by 8 hands in return, the worst of them AJs, which leaves J4o with only 22.9%. 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 offsuit hands it comes 45 of 78. The strongest hand in that group, AKo, is 19.3 points away, and the weakest, 32o, sits 13.8 points below. Measured against the average equity of all 169 hands, 51%, J4o lands -4.9 points from the middle of the pack, and 110 hands in the full ranking are still ahead of it.

Adding players costs equity steadily: 46.1% against one opponent, 28.3% against two, 15.5% against four and 7.6% against eight. That last figure is 68% of an even nine-way share (11.1%). The Chen formula scores this hand at 1 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 J4o reads as 46.1% 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.

J4o 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) 11.5%. 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 1.96% and a four-out gutshot 6.53%. By the river a straight using a hole card completes 3.29% of the time.

Put together, J4o flops a pair or better or a strong draw (an eight-out straight draw) 34.4% of the time — rank 122 of the 156 unpaired hands (tied with 6 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, J4o goes from 46.2% before the flop up to 68.5% when either card pairs, and down to 35.5% 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 36.9%; missing with nothing above J leaves 33.2%.

By board shape: rainbow 46.4%, two-tone 46.0%, monotone 46.9%. A monotone flop in one of your suits gives 55.4%. A paired board gives 46.6%, and a connected board (three ranks within five) 47.6%. The best row in the table is "Either card hits (a matching rank on the flop)" at 68.5%, the worst "and nothing above J" at 33.2%.

The 46.1% 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 46.19% (a gap of 0.09 points). Each equity is taken with the flop out and the turn and river still to come.
