Short deck poker, and why a flush beats a full house

What is actually removed, and what that changes

Take a standard pack and discard every two, three, four and five. Sixteen cards leave the game and thirty-six remain: six, seven, eight, nine, ten, jack, queen, king and ace, in each of the four suits. Nothing else about the deal changes. Two hole cards, five community cards, four betting rounds, showdown.

The sequence is exactly the one set out on the Texas Hold'em page.

The consequences all follow from the same arithmetic. Nine ranks instead of thirteen means the cards you are dealt sit closer together, so more hands connect with more boards. Nine cards per suit instead of thirteen means flushes get harder. And fewer unseen cards means every draw you have is a larger share of what is left, so draws complete far more often than the Hold'em instincts in your head expect.

The ace does double duty as before, and here it matters more. A-K-Q-J-10 is still the highest straight. The lowest is A-6-7-8-9, because the five is gone. The ace plays as a five would, at the bottom of the shortest possible run.

The short deck hand rankings

One swap is close to universal, and it is the one people mean when they say the rankings are different.

A flush outranks a full house because in a 36-card pack it is genuinely rarer. Removing four ranks does not change how many cards of a rank there are (you still have four sixes, four aces), so pairs, trips and full houses arrive at roughly the normal rate. But each suit lost four of its thirteen cards, so the material a flush needs got much scarcer. The rule is not a house quirk; it is the ranking order correcting itself.

The second, less universal change is that some rooms also rank three of a kind above a straight, on the same logic in reverse: with nine ranks in play, straights come in far more often than they do with thirteen. Some rule sets apply this, others leave three of a kind where it normally sits. It is not safe to assume either way, so read the ranking chart the table posts before your first hand. Everything else is unchanged from the standard poker hand rankings: straight flush at the top, two pair above one pair, suits never breaking a tie.

Antes and the button blind

Most short deck games drop the small and big blinds entirely and use an ante structure instead. Every player at the table posts an ante before the cards come out, and the player on the button posts one extra, usually double, sometimes more. That extra ante is often called the button blind, and it is what gives the preflop round something to fight over.

Because there are no blinds, the preflop action starts with the player to the left of the button and moves around to the button, who acts last. That is a real difference from Hold'em, where the big blind has the last word before the flop. In short deck the button has the last word on every single round, which makes it an even better seat than it already was.

Some rooms do run short deck with conventional blinds, and a few use both antes and a big blind. The structure affects how loose the preflop play should be. The more dead money is in the middle before anyone acts, the more hands are worth entering with, so it is worth checking rather than assuming.

How the odds change, in numbers you can use

After the flop in Hold'em there are 47 cards you have not seen. In short deck there are 31. That single number is behind every strategic difference in the game.

Read the flush row carefully, because it is the one that surprises people. A flush draw has fewer outs (nine cards of your suit remain in a full pack, only five in a short one), and yet it still gets there a comparable share of the time, because those five outs are five cards out of 31 rather than nine out of 47. What has really changed is that you will be dealt four to a flush far less often in the first place.

The straight and set rows are where the money moves. An identical number of outs is worth roughly half as much again, because the pack they are hiding in is so much smaller: the same open-ended straight draw goes from about a third to nearly a half. The familiar shortcut of multiplying outs by four with two cards to come becomes closer to multiplying by six, and by three rather than two when only the river is left. That is an estimate, not a precise figure, but it is the right size of estimate to make decisions with at the table.

Hand values compress as a result. Top pair is a weaker holding than it looks, overpairs run much closer against two connected cards, and a flopped set is far from safe. Short deck rewards playing hands that can keep improving and punishes hands that are already as good as they are going to get.

How short deck play differs in practice

• Play more hands, but not any hands. Suited connectors and suited aces gain because straights and flushes carry more weight. Offsuit junk is still junk, and it is worse here because it is dominated more often.
• Respect flushes. They outrank full houses and they are the hands players build their stacks around. Three cards of one suit on the board is a much louder warning in this game than in Hold'em.
• Re-price your draws. Calling a bet with a straight draw is correct far more often than it would be in Hold'em, and a combination draw is frequently the favourite against a made hand.
• Aces gain, big pairs lose ground. The ace still makes the top straight and the nut flush, so it keeps its value. A pair of kings, by contrast, gets outdrawn more often than the same hand in a 52-card game.
• Expect a faster game. Antes from every seat mean there is something worth taking on every hand, so pots are contested more often and stacks move more quickly.

None of that makes short deck a game where a system wins. It is the same poker with different arithmetic, and it carries the same variance, higher if anything, because hands run so close together. There is no betting pattern that overcomes it.

Short deck is also not spread everywhere. It runs in a minority of public lobbies and rather more of the private club apps, which is a good reason to know what a club app actually is before you go hunting for a game.

Playing safely, and the position in Malaysia

Gambling in Malaysia is restricted under the Common Gaming Houses Act 1953 and the Betting Act 1953, and Muslims face an additional prohibition under Sharia law. Nothing on this page says any particular form of real-money play is permitted where you live. This page explains a game; it does not tell you where to bet on it.

If you do play for stakes, short deck deserves a little extra caution for a practical reason: the swings are larger and the pots are contested more often, so a bankroll sized for a Hold'em game will not stretch as far here. Decide the amount before you sit down, keep it separate from money you need, and stop at the number. 18+, and if it has stopped being enjoyable, stop.
