Questions people ask

Why are Omaha equities closer than hold'em?

Four cards give each player six two-card combinations, so almost every hand has something to draw to. Aces against kings is about 82% to 18% in hold'em. In Omaha, A♥A♦K♣7♠ against K♥K♦Q♠2♣ is about 78% to 22%, and aces against a good rundown like J♦10♦9♠8♠ are close to a coin flip, about 52% to 48%.

What is the two-plus-three rule?

Every Omaha hand uses exactly two of your four cards and exactly three from the board. Not one card, not three, and never the board on its own. This calculator scores every hand that way.

How strong are double-suited aces?

A♠A♥K♠K♥ is the best starting hand, but still far from a lock. It wins about 69% against K♦K♣Q♦Q♣ and holds about 45% of the pot against three random hands.

Can a draw be ahead of a made hand?

Often. A♦K♦5♠4♣ on a Q♦J♦4♥ flop has a draw to the best flush, a straight draw (any ten) and a pair. Against top two pair it wins about 63% by the river.

Why do the numbers move a little each time?

Before the flop, or with random hands, the calculator deals 5,000 to 10,000 random run-outs rather than every possible one, so results can shift by about a percent. With known hands on the flop or turn it counts every possible run-out exactly.
