T4s

T4s (ten-four suited) wins 46.7% of the time against a single random opponent, which places it 108th out of the 169 starting hands — the top 63.9% of the range. At a six-handed table (five opponents) its equity falls to 15.7% and its rank moves to 100; nine-handed (eight opponents) it holds 10.8% for rank 100. A suited hand — the flush adds a few points of raw equity.

Its suited/offsuit twin T4o runs at 43.4% (rank 125), a gap of 3.3 points. Sharing a suit is worth exactly those 3.3 points here — nothing about the ranks changes. The hand directly above it in the ranking is T5s at 47.1%, and directly below is 97o at 46.4%, so three hands are packed into a band of 0.7 points.

Played heads-up against each of the other 168 hands, T4s is a favourite against 61 of them and an underdog against 107. Its best matchup is 94o at 74.2% and its worst is TT at 12.5% — a spread of 61.7 points, which is why calling T4s simply "strong" or "weak" says very little. 1 opponents land inside one point of a coinflip, the closest being 22 at 49.7%.

T4s dominates 8 hands that share one of its ranks, pushing hardest against 94o at 74.2%. It is dominated by 8 hands in return, the worst of them ATs, which leaves T4s with only 27.2%. 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 suited hands it comes 52 of 78. The strongest hand in that group, AKs, is 20.5 points away, and the weakest, 32s, sits 10.8 points below. Measured against the average equity of all 169 hands, 51%, T4s lands -4.3 points from the middle of the pack, and 107 hands in the full ranking are still ahead of it.

Adding players costs equity steadily: 46.7% against one opponent, 30.5% against two, 18.3% against four and 10.8% against eight. That last figure is 97% of an even nine-way share (11.1%). The Chen formula scores this hand at 2 points, and it arrives 0.3% of the time (4 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 T4s reads as 46.7% 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.

T4s 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) 9.68%. 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. For flushes, two or more of its suit land on the flop 11.8% of the time (a made flush 0.842%), and a flush is complete by the river 6.40%.

Put together, T4s flops a pair or better or a strong draw (a flush draw or an eight-out straight draw) 44.7% of the time — rank 33 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, T4s goes from 46.5% before the flop up to 67.3% when either card pairs, and down to 36.6% when both miss. It connects 32.4% of the time (6,356 of 19,600 flops). Missing with a card above T on board leaves 37.0%; missing with nothing above T leaves 35.2%.

By board shape: rainbow 45.3%, two-tone 47.3%, monotone 47.3%. Two of your suit (a flush draw) gives 58.9% (10.9% of flops), and three of your suit (a made flush) 93.7% (0.842%). A paired board gives 45.8%, and a connected board (three ranks within five) 50.4%. The best row in the table is "Three of your suit (made flush)" at 93.7%, the worst "and nothing above T" at 35.2%.

The 46.7% 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 46.53% (a gap of 0.17 points). Each equity is taken with the flop out and the turn and river still to come.
