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.
Interleaved ranks
One hand has the highest card, the other has the two middle ones. The high card wins most boards where nothing pairs, but either middle card pairing beats it unless the high card pairs too, which keeps these closer than the top card suggests.

When calling with KQo is right
If you call an all-in of S with KQo and know you are up against exactly A5s, you win 39.72% of a pot that holds 2S plus whatever dead money D was already in the middle (blinds, antes, earlier bets). Calling breaks even when 39.72% × (2S + D) = S, so D ÷ S = 1 ÷ 0.3972 − 2 = 0.517. A 10 bb shove needs at least 5.2 bb of dead money before calling it with KQo 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: KQo (dealt as K♦Q♥, the most common suit pattern) facing a 10 bb all-in with 2.5 bb already in the middle, against a range of exactly A5s. 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 A5s at 60.31% here, 0.03 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.
