87o

87o (eight-seven offsuit) wins 45.1% of the time against a single random opponent, which places it 117th out of the 169 starting hands — the top 69.2% of the range. At a six-handed table (five opponents) its equity falls to 14.9% and its rank moves to 111; nine-handed (eight opponents) it holds 10.1% for rank 113. A connector — straight potential, but nothing else to lean on.

Its suited/offsuit twin 87s runs at 47.9% (rank 101), 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 J3o at 45.3%, and directly below is T2s at 44.8%, so three hands are packed into a band of 0.5 points.

Played heads-up against each of the other 168 hands, 87o is a favourite against 42 of them and an underdog against 126. Its best matchup is 72o at 72.5% and its worst is 88 at 13.2% — a spread of 59.3 points, which is why calling 87o simply "strong" or "weak" says very little. 2 opponents land inside one point of a coinflip, the closest being 33 at 50.8%.

87o dominates 8 hands that share one of its ranks, pushing hardest against 72o at 72.5%. It is dominated by 8 hands in return, the worst of them 98s, which leaves 87o with only 27.9%. 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 48 of 78. The strongest hand in that group, AKo, is 20.3 points away, and the weakest, 32o, sits 12.8 points below. Measured against the average equity of all 169 hands, 51%, 87o lands -5.9 points from the middle of the pack, and 116 hands in the full ranking are still ahead of it.

Adding players costs equity steadily: 45.1% against one opponent, 30.3% against two, 18.4% against four and 10.1% against eight. That last figure is 91% of an even nine-way share (11.1%). The Chen formula scores this hand at 5 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 87o reads as 45.1% 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.

87o 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) 9.29%. By the river it has made a pair or better 48.7% of the time.

For straights, the flop completes one 1.31% of the time (256 flops), gives an eight-out draw 9.71% and a four-out gutshot 16.8%. By the river a straight using a hole card completes 9.12% of the time.

Put together, 87o flops a pair or better or a strong draw (an eight-out straight draw) 42.0% of the time — rank 79 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, 87o goes from 45.1% before the flop up to 69.7% when either card pairs, and down to 33.2% when both miss. It connects 32.4% of the time (6,356 of 19,600 flops). Missing with a card above 8 on board leaves 33.0%; missing with nothing above 8 leaves 35.5%.

By board shape: rainbow 45.0%, two-tone 44.9%, monotone 46.6%. A monotone flop in one of your suits gives 55.0%. A paired board gives 41.4%, and a connected board (three ranks within five) 50.1%. The best row in the table is "Either card hits (a matching rank on the flop)" at 69.7%, the worst "and at least one card above 8" at 33.0%.

The 45.1% 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 45.05% (a gap of 0.05 points). Each equity is taken with the flop out and the turn and river still to come.
