Short Deck Odds Calculator (6+ Hold'em)

Six-plus Hold'em equity with the correct 36-card deck and hand rankings: flushes beat full houses, and the ace plays low in A-6-7-8-9.

Using the Short Deck calculator

The deck on the right shows only the 36 cards that exist in 6+ Hold’em. Enter two cards per player and the board, and the equity, win and tie percentages update automatically. Postflop results are exact enumerations; preflop heads-up (201,376 boards) is exact too.

How the odds change with 36 cards

Straights come more often than flushes with 36 cards, which is why the flush is ranked above the full house on most sites; the calculator already ranks hands that way. A-6-7-8-9 is also a straight, since the ace fills in for the missing five, while A-K-Q-J-T remains the top straight. Sets hit more often too: a pocket pair makes a set on the flop about 17% of the time (versus 12% in Hold’em), and open-enders hit around 46% by the river. The shorter deck also changes the shortcut for turning outs into a percentage: the rule of 2 and 4 becomes 3 and 6, because with 31 unseen cards after the flop each out is worth about 3% per street. The outs calculator lets you set the number of unseen cards for exact figures.

Short Deck preflop equities

MatchupEquity
A♥A♦ vs J♠T♠62.5% / 37.5%
K♠K♥ vs A♦Q♦about 58% / 42%
J♠T♠ vs 7♥7♦about 54% / 46%
A♣K♣ vs 9♠8♠about 56% / 44%

Suited connectors hold up remarkably well, which is why aggressive rundown play is the standard Short Deck strategy.

Frequently asked questions

Which Short Deck rules does the calculator use?
The most common online rules: deuces through fives removed, flush ranks above full house, straight ranks above three of a kind, and A-6-7-8-9 is the lowest straight. Some live rooms rank trips above straights; those spots will differ slightly.
Why are pocket aces weaker in Short Deck?
With 16 cards removed there are more straights and sets, and every opponent’s hand is closer in rank to yours. AA is still the best hand, but it is roughly 63% against JTs instead of 80% in regular Hold’em.
How many outs does a flush draw have in Short Deck?
Five, not nine. Each suit has only nine cards, so with four of them seen you have five left. A flush draw hits by the river about 30% of the time, an open-ended straight draw with 8 outs about 46%.
