43o

43o (four-three offsuit) wins 35.2% of the time against a single random opponent, which places it 164th out of the 169 starting hands — the top 97% of the range. At a six-handed table (five opponents) its equity falls to 10.7% and its rank moves to 156; nine-handed (eight opponents) it holds 7.5% for rank 149. A connector — straight potential, but nothing else to lean on.

Its suited/offsuit twin 43s runs at 38.7% (rank 150), a gap of 3.5 points. Losing the shared suit costs 3.5 points of raw equity. The hand directly above it in the ranking is 32s at 35.9%, and directly below is 72o at 34.4%, so three hands are packed into a band of 1.5 points.

Played heads-up against each of the other 168 hands, 43o is a favourite against 5 of them and an underdog against 163. Its best matchup is 32o at 54.8% and its worst is 44 at 12.5% — a spread of 42.3 points, which is why calling 43o simply "strong" or "weak" says very little. 2 opponents land inside one point of a coinflip, the closest being 42s at 50.7%.

It is dominated by 8 hands in return, the worst of them A4s, which leaves 43o with only 25.0%. 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 73 of 78. The strongest hand in that group, AKo, is 30.2 points away, and the weakest, 32o, sits 2.9 points below. Measured against the average equity of all 169 hands, 51%, 43o lands -15.8 points from the middle of the pack, and 163 hands in the full ranking are still ahead of it.

Adding players costs equity steadily: 35.2% against one opponent, 22.5% against two, 12.9% against four and 7.5% against eight. That last figure is 68% of an even nine-way share (11.1%). The Chen formula scores this hand at 3 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 43o reads as 35.2% 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.

43o 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) 3.65%. By the river it has made a pair or better 48.7% of the time.

For straights, the flop completes one 0.980% of the time (192 flops), gives an eight-out draw 6.37% and a four-out gutshot 14.8%. By the river a straight using a hole card completes 6.96% of the time.

Put together, 43o flops a pair or better or a strong draw (an eight-out straight draw) 38.8% of the time — rank 94 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, 43o goes from 35.1% before the flop up to 59.7% when either card pairs, and down to 23.3% when both miss. It connects 32.4% of the time (6,356 of 19,600 flops). Missing with a card above 4 on board leaves 23.3%; missing with nothing above 4 leaves 27.4%.

By board shape: rainbow 35.0%, two-tone 35.0%, monotone 37.3%. A monotone flop in one of your suits gives 44.4%. A paired board gives 33.1%, and a connected board (three ranks within five) 34.7%. The best row in the table is "Either card hits (a matching rank on the flop)" at 59.7%, the worst "and at least one card above 4" at 23.3%.

The 35.2% 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 35.15% (a gap of 0.05 points). Each equity is taken with the flop out and the turn and river still to come.
