Standard poker players transitioning to high-stakes circles often encounter a variant that has “shaved” the deck down to its most explosive components. Known as Short Deck Poker (or 6+ Hold’em), this game originated in the high-stakes rooms of Macau, championed by poker icons like Phil Ivey and Tom Dwan [1].
The fundamental difference lies in the deck composition: all 2s, 3s, 4s, and 5s are removed, leaving a 36-card deck. This reduction does more than just speed up the game; it fundamentally alters the mathematical probability of making certain hands, necessitating a complete overhaul of the traditional hand ranking system.

The Standard Poker Ranking Hierarchy
In traditional Texas Hold’em, a 52-card deck is used. The probability of forming hands follows a strict mathematical progression based on the frequency of those combinations occurring naturally.
- Royal Flush: The unbeatable 10-J-Q-K-A of the same suit.
- Straight Flush: Five consecutive cards of the same suit.
- Four of a Kind: Four cards of the same rank.
- Full House: Three of a kind plus a pair.
- Flush: Five cards of the same suit.
- Straight: Five consecutive cards of mixed suits.
- Three of a Kind: Three cards of the same rank.
- Two Pair: Two different pairs.
- One Pair: Two cards of the same rank.
- High Card: The highest individual card in the hand.
In this environment, “junk” cards are common. Just as manufacturers have refined processes for how dice and playing cards are made to prevent cheating, the 52-card deck is designed to provide a wide spectrum of hand strengths, where a single pair often wins the pot.
The highest hand is the Royal Flush, which consists of 10, Jack, Queen, King, and Ace of the same suit. In a standard 52-card deck, this is the rarest and most powerful combination possible.
Hand rankings are based on mathematical probability. In a 52-card deck, the odds of being dealt a Full House are lower than the odds of completing a Flush, making the Full House the superior hand.
Short Deck Variations: Why Rankings Shift
When you remove the 16 lowest cards (2 through 5) from the deck, the “mathematical landscape” shifts. Because there are fewer cards, the likelihood of hitting specific draws increases, while others become significantly harder.
1. Flush Beats a Full House
In a standard 52-card game, you have 13 cards of each suit. In Short Deck, you only have nine. This makes it mathematically rarer to hit a flush than in the standard game. Conversely, because the deck is more “concentrated” with high cards, pairing up to make a full house happens more frequently. According to BetMGM, the flush is moved above the full house in Short Deck rankings to reflect this difficulty [2].
2. The “Straight” Debate (Three of a Kind vs. Straight)
There is a minor schism in Short Deck rules regarding Three of a Kind (Sets) and Straights.
Traditional Short Deck: In some venues, Three of a Kind beats a Straight because it is mathematically harder to hit a set than a straight with a 36-card deck.
Standardized Short Deck (Triton/WSOP): Most major tournaments, including the World Series of Poker, have kept the Straight above Three of a Kind to maintain game flow and prevent “trapping” with sets [3].
3. The Low Straight (A-6-7-8-9)
In Short Deck, the Ace retains its dual role as high and low. However, since 2-5 are gone, the lowest possible straight is A-6-7-8-9 [4]. Beginners often miss this, folding what is actually a powerful “wheel” straight.
Because cards 2 through 5 are removed, there are only nine cards of each suit available instead of thirteen. This makes hitting a Flush mathematically rarer and harder to achieve than a Full House in a 36-card deck.
The lowest straight is A-6-7-8-9. Since the 2, 3, 4, and 5 cards are removed from the deck, the Ace acts as the low card to connect with the 6, 7, 8, and 9.
It depends on the specific house rules. While it is mathematically harder to hit a set, many major tournament series like the WSOP use standardized rules where a Straight still beats Three of a Kind to encourage more action.
Strategic Adjustments and Probability
The shift in rankings is driven by a massive increase in hand equity. In standard Hold’em, you are dealt pocket Aces roughly 1 in 221 hands. In Short Deck, that frequency jumps to 1 in 100 [3].
| Hand Type | Standard Hold’em Odds | Short Deck Odds |
|---|---|---|
| Pocket Aces | 0.45% | 1.0% |
| Hitting a Set (on Flop) | 11.8% | 17.0% |
| Open-Ended Straight Draw (by River) | 32% | 48% |
Because straights are so much easier to complete, hands like Top Pair/Top Kicker—which are staples in standard poker—become significantly more vulnerable. This high-variance nature mirrors the volatility seen in other betting markets, such as those discussed in understanding the odds in sports betting.
The probability increases significantly due to the smaller deck. You will receive pocket Aces approximately once every 100 hands in Short Deck, compared to once every 221 hands in standard Texas Hold’em.
With only 36 cards, the likelihood of opponents hitting sets or straights is much higher. An open-ended straight draw has a nearly 50% chance of completing by the river, making one-pair hands highly vulnerable.
Betting Structure: Antes vs. Blinds
Most Short Deck games abandon the traditional Small Blind/Big Blind format. Instead, they use an “Ante-only” structure. Every player posts an ante, and the dealer (the “Button”) posts a double ante [4]. This creates a massive pot before the cards are even dealt, incentivizing aggressive play and frequent “shoves” (all-in bets).
In most games, there are no traditional blinds. Instead, every player posts a standard ante, and the player on the button posts a double ante to initiate the pot and drive action.
Yes, it creates a much larger initial pot relative to stack sizes. This incentivizes a more aggressive style of play, leading to more frequent pre-flop raises and all-in shoves compared to blind-based games.
Summary of Key Takeaways
Core Hand Ranking Differences
- Flush beats Full House: Always the case in 6+ Hold’em due to the reduction of suited cards from 13 down to 9.
- The Ace-Low Straight: The “wheel” in Short Deck is A-6-7-8-9.
- Sets vs. Straights: Check the house rules; while most pros prefer Straights beating Three of a Kind, some local variations flip them.
Action Plan for New Players
- Tighten Your Range: Pocket Kings and Queens are significantly weaker in Short Deck than in standard games because opponents hit sets and straights more often.
- Value Suited Connectors: Since flushes beat full houses, suited cards like J-Q suited gain massive value.
- Adjust Your Math: Remember that you have a nearly 50% chance of hitting an open-ended straight draw by the river.
- Check the “Set” Rule: Before sitting down, confirm whether Three of a Kind beats a Straight at that specific table.
Short Deck Poker isn’t just “faster” poker; it is a game of maximized equity where the “nuts” (the best possible hand) changes rapidly on every street. Mastering the ranking variations is the first step toward surviving the high-variance world of 6+ Hold’em.
| Feature | Standard Hold’em | Short Deck (6+) |
|---|---|---|
| Deck Size | 52 Cards | 36 Cards (2-5 removed) |
| Hand Ranking: Flush | Beats Straight, Loses to Full House | Beats Full House (Mathematically Rare) |
| Lowest Straight | A-2-3-4-5 | A-6-7-8-9 |
| Trips vs. Straight | Straight Beats Three of a Kind | Varies (Usually Straight beats Three) |
| Aces Probability | 1 in 221 hands | 1 in 100 hands |
The most critical steps are memorizing the shifted hand rankings—specifically that a Flush beats a Full House—and tightening your starting hand range to account for the increased frequency of powerful opponent hands.
Suited connectors like J-Q suited increase in value because Flushes are the premier powerhouse hand in this format. Since they are harder to hit but beat Full Houses, they offer significant ‘nut’ potential.
