A2o

A2o (ace-deuce offsuit) wins 54.9% of the time against a single random opponent, which places it 60th out of the 169 starting hands — the top 35.5% of the range. At a six-handed table (five opponents) its equity falls to 16.3% and its rank moves to 94; nine-handed (eight opponents) it holds 10.5% for rank 109. An ace-high hand — watch out for kicker trouble and domination.

Its suited/offsuit twin A2s runs at 57.6% (rank 43), a gap of 2.7 points. Losing the shared suit costs 2.7 points of raw equity. The hand directly above it in the ranking is K4s at 54.9%, and directly below is Q7s at 54.4%, so three hands are packed into a band of 0.5 points.

Played heads-up against each of the other 168 hands, A2o is a favourite against 132 of them and an underdog against 36. Its best matchup is K2o at 76.3% and its worst is AA at 6.7% — a spread of 69.6 points, which is why calling A2o simply "strong" or "weak" says very little. 1 opponents land inside one point of a coinflip, the closest being 76s at 50.9%.

A2o dominates 8 hands that share one of its ranks, pushing hardest against K2o at 76.3%. It is dominated by 8 hands in return, the worst of them AKs, which leaves A2o with only 24.8%. 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 offsuit hands it comes 22 of 78. The strongest hand in that group, AKo, is 10.5 points away, and the weakest, 32o, sits 22.6 points below. Measured against the average equity of all 169 hands, 51%, A2o lands +3.9 points from the middle of the pack, and 59 hands in the full ranking are still ahead of it.

Adding players costs equity steadily: 54.9% against one opponent, 35.4% against two, 19.6% against four and 10.5% against eight. That last figure is 95% 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 A2o reads as 54.9% 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.

A2o 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) 17.9%. By the river it has made a pair or better 48.7% of the time.

For straights, the flop completes one 0.327% of the time (64 flops), gives an eight-out draw 0.0000% and a four-out gutshot 11.3%. By the river a straight using a hole card completes 3.09% of the time.

Put together, A2o flops a pair or better or a strong draw (an eight-out straight draw) 32.8% of the time — rank 155 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, A2o goes from 54.9% before the flop up to 72.3% when either card pairs, and down to 46.6% when both miss. It connects 32.4% of the time (6,356 of 19,600 flops). Nothing ranks above A, so a miss never brings an overcard.

By board shape: rainbow 55.7%, two-tone 54.6%, monotone 52.9%. A monotone flop in one of your suits gives 61.3%. A paired board gives 60.1%, and a connected board (three ranks within five) 49.2%. The best row in the table is "Either card hits (a matching rank on the flop)" at 72.3%, the worst "Neither card hits" at 46.6%.

The 54.9% 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 54.93% (a gap of 0.03 points). Each equity is taken with the flop out and the turn and river still to come.
