AQo vs JTs ace-queen offsuit against jack-ten suited
All-in before the flop, ace-queen offsuit wins 59.5% of boards, jack-ten suited wins 40.0%, and 0.5% split the pot. AQo is a 1.48 to 1 favourite. These are not samples: the engine dealt every one of the 1,712,304 possible five-card boards for each of the 3 ways the suits can line up, and the working is below.
Equity counts a split pot as half a win for each side, which is why the two equities add to 100% and the two win rates do not.
Two higher cards against two lower cards
Neither hand is made. The higher cards win most boards where nothing happens, or where both hands pair one card. The lower hand wins when it pairs and the higher one does not, or makes a straight or flush, so suited and connected lower cards do noticeably better than their ranks suggest.

When calling with JTs is right
If you call an all-in of S with JTs and know you are up against exactly AQo, you win 40.28% of a pot that holds 2S plus whatever dead money D was already in the middle (blinds, antes, earlier bets). Calling breaks even when 40.28% × (2S + D) = S, so D ÷ S = 1 ÷ 0.4028 − 2 = 0.483. A 10 bb shove needs at least 4.8 bb of dead money before calling it with JTs stops losing chips. Nobody shows you their hand, though: against a real shove you are calling a range, and the push/fold charts already account for it.
Open this as a spot: JTs (dealt as J♥T♥, the most common suit pattern) facing a 10 bb all-in with 2.5 bb already in the middle, against a range of exactly AQo. The calculator samples runouts rather than dealing all of them, so expect its equity to land within a few tenths of a point of the exact figure for that deal. Change the pot, the bet or the range and it reprices.
Each hand has its own page with its equity against all 169 starting hands and its push/fold range at every stack depth.

- Exhaustive, not sampled. With four cards dealt, 48 remain, and there are C(48, 5) = 1,712,304 five-card boards. For each suit pattern our Rust engine (the same WebAssembly file the trainer runs) evaluated both seven-card hands on every board and counted wins, splits and losses. The board counts in the suit table are exact; anyone with an enumerator can reproduce them digit for digit.
- Suit patterns. Two deals are the same pattern when one becomes the other by renaming suits (clubs to hearts, say), which cannot change who wins. Each pattern is enumerated once and weighted by how many of the 48 deals it stands for.
- Cross-check. The site's independent Monte Carlo matrix (200,000 random boards per matchup, used on the starting-hand pages) has AQo at 59.78% here, 0.06 points from the exact figure. The build fails if any matchup disagrees by more than 0.4 points.
- All-in preflop only. This is the equity when the money goes in before the flop and five cards are dealt with no more decisions. It says nothing about how the hands play when there is betting left.
