Interpreting the result
Hand classes run from high card through straight flush. Each player uses the best five of their seven cards, including the option of playing the board. Equity adds a fractional share for each tied pot; it is a showdown probability, not an expected monetary return.
How to use it
- Enter two cards for each known hand or type random.
- Add the board and any dead cards, then choose the simulation size.
- Calculate equity and inspect the hand-class distribution and standard error.

Frequently asked questions
What does random mean?
Every available two-card hand is equally likely. There are no betting ranges, folding assumptions, side pots or rake.
Why do AA versus KK results differ?
Suits matter. As Ah versus Ks Kh yields 82.6366% equity for aces. Other suit combinations can be closer to 81.9%.
What is standard error?
It estimates the sampling uncertainty in equity. About twice the standard error is a rough 95% interval. Exact enumeration has no sampling error.
