J5o

J5o (jack-five offsuit) wins 47.2% of the time against a single random opponent, which places it 106th out of the 169 starting hands — the top 62.7% of the range. At a six-handed table (five opponents) its equity falls to 12.8% and its rank moves to 140; nine-handed (eight opponents) it holds 7.8% for rank 145. Two unconnected offsuit cards — the class of hand most often overvalued.

Its suited/offsuit twin J5s runs at 50.0% (rank 90), 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 Q2o at 47.3%, and directly below is T5s at 47.1%, so three hands are packed into a band of 0.2 points.

Played heads-up against each of the other 168 hands, J5o is a favourite against 78 of them and an underdog against 90. Its best matchup is T5o at 73.9% and its worst is JJ at 7.3% — a spread of 66.6 points, which is why calling J5o simply "strong" or "weak" says very little.

J5o dominates 8 hands that share one of its ranks, pushing hardest against T5o at 73.9%. It is dominated by 8 hands in return, the worst of them AJs, which leaves J5o with only 23.3%. 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 43 of 78. The strongest hand in that group, AKo, is 18.2 points away, and the weakest, 32o, sits 14.9 points below. Measured against the average equity of all 169 hands, 51%, J5o lands -3.8 points from the middle of the pack, and 105 hands in the full ranking are still ahead of it.

Adding players costs equity steadily: 47.2% against one opponent, 29.2% against two, 15.9% against four and 7.8% against eight. That last figure is 70% 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 J5o reads as 47.2% 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.

J5o 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) 12.1%. 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 2.61% and a four-out gutshot 6.53%. By the river a straight using a hole card completes 3.64% of the time.

Put together, J5o flops a pair or better or a strong draw (an eight-out straight draw) 35.0% of the time — rank 111 of the 156 unpaired hands (tied with 4 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, J5o goes from 47.2% before the flop up to 69.4% when either card pairs, and down to 36.5% 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 37.6%; missing with nothing above J leaves 34.8%.

By board shape: rainbow 47.4%, two-tone 47.0%, monotone 47.9%. A monotone flop in one of your suits gives 56.6%. A paired board gives 47.2%, and a connected board (three ranks within five) 50.6%. The best row in the table is "Either card hits (a matching rank on the flop)" at 69.4%, the worst "and nothing above J" at 34.8%.

The 47.2% 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 47.18% (a gap of 0.02 points). Each equity is taken with the flop out and the turn and river still to come.
