Short Deck Holdem, also known as Six Plus Holdem, is a variant of Texas Holdem poker that uses a reduced deck of 36 cards. All cards ranked 2 through 5 are removed, leaving only cards from 6 through Ace. The game retains the basic structure of Holdem—two hole cards per player, five community cards, and four betting rounds—but introduces significant changes to hand rankings and probabilities that fundamentally alter strategy.
Short Deck Holdem studies and practices a modified form of No-Limit Texas Holdem played with a stripped deck. The central question it poses is: how do the strategic principles of poker change when the deck is reduced, hand values are reordered, and the probability of making strong hands increases dramatically? Players must navigate a game where the frequency of flushes, straights, and full houses is much higher than in standard Holdem, and where the relative strength of hands shifts—for example, a flush now beats a full house, and three of a kind beats a straight.
The stakes are practical: players who apply standard Holdem logic to Short Deck will systematically misvalue hands, misjudge drawing odds, and make costly errors. The game rewards those who internalize its unique probabilities and adjust their preflop ranges, postflop play, and risk management accordingly.
Short Deck Holdem emerged in the private high-stakes poker games of Asia, particularly in Macau and the Philippines, during the early 2010s. It was not a formal invention but a gradual adaptation by players seeking a faster, more action-oriented game. The reduced deck increases the frequency of made hands and draws, leading to larger pots and more volatile outcomes. The variant gained international visibility when it was featured in high-profile televised cash games and tournaments, most notably the Triton Poker Series, which began including Short Deck events around 2017.
The game is not a historical precursor to standard Holdem but a deliberate modification of it. Its relationship to the parent game is one of selective inheritance: it keeps the betting structure and community card format but discards the lower ranks and reorders hand values. This makes Short Deck both familiar and disorienting to experienced Holdem players, who must unlearn many ingrained intuitions.
The most fundamental approach to Short Deck Holdem is to treat it as a problem of recalculated probabilities. Because the deck has only 36 cards instead of 52, the odds of completing draws change substantially. For example, a flush draw on the flop has 9 outs out of 31 remaining unseen cards (roughly 29% per street), compared to 9 out of 47 in standard Holdem (about 19%). A straight draw also has different odds because the deck lacks low cards that can complete certain straight sequences.
This approach focuses on deriving correct pot odds, implied odds, and equity calculations from the new deck composition. It addresses the central question of hand valuation by building a quantitative foundation. Its limitation is that raw probability tables, while necessary, do not capture the strategic complexity of opponent modeling, bet sizing, and range construction. A player who memorizes odds but ignores opponent tendencies will still be exploitable.
A more sophisticated approach adapts the modern, range-based thinking of elite Holdem to the Short Deck environment. Instead of treating hands as isolated, this approach considers how the reduced deck compresses hand values. Because low cards are absent, starting hands that are marginal in standard Holdem—like suited connectors such as 9-8 or 10-9—become much stronger, while high-card hands like A-K lose some of their relative advantage. The removal of low cards also means that many more flops connect with a player's range, leading to frequent confrontations on marginal holdings.
This approach addresses the problem of preflop hand selection and postflop decision-making by constructing ranges that reflect the new distribution of hand strengths. It recognizes that the game rewards aggression and hand reading more than patience and trapping, because the probability of improvement is so high. Its limitation is that it requires a deep understanding of both standard Holdem theory and the specific adjustments for Short Deck, and it can be difficult to apply without extensive experience or solver-based study.
The most recent and technically demanding approach uses computer solvers to compute game theory optimal (GTO) strategies for Short Deck Holdem. Solvers analyze the game tree—all possible actions, board runouts, and opponent responses—to find strategies that cannot be systematically exploited. This approach has become influential in standard Holdem and has been extended to Short Deck as the variant gained popularity.
The solver approach addresses the question of what correct play looks like in a mathematically rigorous sense, independent of opponent tendencies. It reveals that Short Deck's optimal strategies differ markedly from standard Holdem: for example, the solver often recommends calling with weaker hands on the flop because the high probability of improvement justifies continued investment. It also shows that the value of suited hands increases dramatically, since flushes are both more common and now beat full houses.
The limitation of this approach is that solvers are computationally expensive and their outputs are complex. They provide reference strategies but not simple rules of thumb. Moreover, human players cannot perfectly execute GTO strategies in real time, so the practical value lies in understanding the principles the solver reveals—such as the importance of suitedness and the need to defend more widely against bets—rather than memorizing exact frequencies.
These three approaches are not rival schools but complementary layers of understanding. The probability-first approach provides the foundation: without correct odds, no strategic reasoning can be sound. The range-based approach builds on that foundation by organizing hands into coherent categories and developing heuristics for real-time play. The solver approach offers a gold standard for correctness, against which the other approaches can be tested and refined.
In practice, serious Short Deck players combine all three. They use probability calculations to evaluate draws, range thinking to construct preflop and postflop strategies, and solver insights to check whether their intuitions are sound. The field has not seen a single dominant paradigm; instead, it has evolved through the progressive application of tools and concepts developed for standard Holdem, adapted to the unique constraints of the reduced deck.
Short Deck Holdem remains a niche variant within the broader poker world, but it has a dedicated following among high-stakes cash game players and tournament participants. It is not a replacement for standard Holdem but a distinct game that tests different skills: adaptability, comfort with volatility, and the ability to recalculate familiar situations from first principles. The game continues to be studied informally through hand analysis, discussion forums, and commercial training content, though it lacks the extensive academic or solver-based literature that exists for standard Holdem.
The most important ongoing development is the refinement of preflop ranges and postflop strategies through solver work, which has gradually replaced earlier guesswork. As more players gain access to solver technology, the strategic frontier of Short Deck is likely to narrow, though the game's inherent variance and the psychological demands of high-stakes play will ensure that it remains a challenging and dynamic form of poker.
