How the calculator works
- Exact, when it can count every deal
- If the cards still to come can be dealt every possible way in a few million hands, the calculator deals each one once and counts who wins. Hold'em before the flop with two known hands is 1,712,304 boards.
- Simulated, when it cannot
- A random hand, or Stud and Razz with four cards to come, can finish billions of ways, so the calculator deals 100,000 random hands instead (40,000 in Omaha, where every deal scores 60 hands a player). Run it again and the last digit may move.
- Dead cards
- In Stud, Razz and 2-7, cards you saw folded or thrown away cannot come to anyone. Add them as dead cards and the calculator leaves them out of the deck.
- Win, tie and chance to win
- Win is how often a hand takes the whole pot. Tie is how often it splits. The big number is its equity: wins plus its share of each split, which is the hand's fair share of the pot.
What the numbers do not tell you
The chances assume every hand goes to showdown. In a real hand, players fold, and a bet can win a pot before the last card. The calculator shows what each hand wins if all the cards are dealt out, which is what happens when someone is all in and called.
