Short Deck (6+) Hold’em Guide
Welcome, grinders and aspiring pros, to an in-depth exploration of short deck poker, also known as 6+ Hold’em. This exhilarating variant has rapidly gained traction in high-stakes circles and online rooms, captivating players with its unique blend of aggression, dynamic equities, and strategic depth. If you’re looking to expand your poker arsenal beyond the traditional confines of No-Limit Hold’em, understanding the nuances of Short Deck is not just an advantage—it’s a necessity.
Unlike its 52-card counterpart, Short Deck strips out all cards from 2 through 5, leaving a lean 36-card deck ranging from 6s to Aces. This seemingly simple change fundamentally alters hand equities, probabilities, and optimal strategies. Suddenly, strong starting hands become even stronger, draws hit with alarming frequency, and aggression is rewarded. Our goal in this comprehensive guide is to equip you with the mathematical foundations, strategic frameworks, and practical insights needed to master this high-octane format, bridging the gap between GTO theory and exploitative adjustments to give you an edge at the tables.
Key Concepts: Short Deck (6+) Hold’em
| Concept | Description |
|---|---|
| Deck Composition | Only 36 cards (6s through Aces). All 2s, 3s, 4s, 5s are removed. |
| Hand Rankings | Flush > Full House. All other rankings remain standard. |
| Straights | An Ace can play high or low. The lowest straight is A-6-7-8-9. |
| Pre-flop Equity | Equities run much closer. Pairs, suited connectors, and Broadways gain significant value. |
| Action Level | Significantly higher due to tighter ranges, frequent draws, and higher equities. |
| Pot Odds & Outs | Fewer cards mean different probabilities for hitting draws. Must re-learn “Rule of 2 and 4.” |
Theory Section: The Mathematical Foundations
Deck Composition and Its Impact
The reduction from a 52-card to a 36-card deck is the bedrock upon which all Short Deck strategy is built. Removing the low cards (2s-5s) has several profound implications:
- Fewer Cards, Higher Frequencies: With 16 fewer cards, the probability of being dealt specific cards or combinations increases. This means pocket pairs, suited connectors, and broadway hands appear more often, leading to stronger starting hands on average.
- Increased Pairing Probability: Because there are fewer cards, the chances of hitting a set with a pocket pair, or pairing one of your hole cards on the flop, increase. In NLHE, you hit a set ~12% of the time. In Short Deck, it’s roughly 17%.
- Altered Straight Possibilities: The absence of 2s-5s means straights require a different set of cards. The lowest possible straight is A-6-7-8-9, as A acts as a 5. Other straights are 6-7-8-9-T, 7-8-9-T-J, etc. This changes the texture of straight draws.
Hand Ranking Shifts: Flush > Full House
This is arguably the most critical difference to internalize. In Short Deck, a flush beats a full house. Why? It’s all about combinatorics:
- Full Houses are Easier: With fewer cards in the deck, it’s statistically easier to make a full house. If you have a pair, there are only two cards left of that rank, but the overall card pool is smaller, leading to a higher probability of hitting trips and then another pair on board.
- Flushes are Harder (Relatively): While there are still 9 cards of each suit, the overall smaller deck means fewer non-suited cards exist. However, the probability of forming a full house increases more significantly than that of a flush. Consequently, flushes are less frequent than full houses in Short Deck.
This reversal drastically impacts how you value your hands, especially on turn and river. Don’t fall into the trap of overvaluing a full house against a potential flush!
Pre-flop Equity Fundamentals
The reduced deck significantly compresses pre-flop equities. The “gap” between premium hands and speculative hands shrinks. This leads to more multi-way pots and higher variance.
Consider these approximate pre-flop equities (heads-up, against a random hand):
| Hand | NLHE Equity (vs. Random) | Short Deck Equity (vs. Random) |
|---|---|---|
| AA | ~85% | ~75% |
| KK | ~82% | ~72% |
| AKs | ~67% | ~65% |
| ~80% | ~70% | |
| JTs | ~50% | ~58% |
| 87s | ~46% | ~54% |
Notice the smaller drop-off in equity for hands like AA and KK, and the significant boost for suited connectors (like JTs, 87s). This is because draws hit more often, and even marginal hands have better implied odds. This fundamental shift encourages playing a wider range of hands, especially those with good post-flop playability and redraw potential.
Pot Odds & Implied Odds in Short Deck
Calculating your odds of hitting a draw correctly is paramount. The “Rule of 2 and 4” (multiply outs by 2 for turn, by 4 for river) is no longer accurate. Here’s a revised guide for Short Deck:
| Draw Type | NLHE Outs | Short Deck Outs | Approx. % (Flop to Turn) | Approx. % (Flop to River) |
|---|---|---|---|---|
| Open-Ended Straight Draw (OESD) | 8 | 5 (e.g., KJT9 has 4 Qs, 4 8s in NLHE, but 4 Qs, 1 8 in SD if 8 is 6-card) – requires careful counting! | 14% | 28% |
| Gutshot Straight Draw | 4 | 3 (e.g., KJT8 has 4 9s in NLHE, 3 9s in SD) | 8% | 16% |
| Flush Draw | 9 | 9 | 25% | 45% |
| Pair to Set | 2 | 2 | 11.5% | 22% |
| OESD + Flush Draw (Combo Draw) | 15 | 14 (5 for straight + 9 for flush – 1 overlap) | 35% | 60% |
Note: Straight outs in Short Deck are trickier due to the A-6-7-8-9 straight. Always count your specific outs carefully. For example, if you have KQT8 and the board is J9, you have a gutshot. In NLHE, that’s 4 Tens. In Short Deck, it’s 3 Tens.
Implied Odds: Given the higher frequency of hitting draws and the tendency for players to commit with strong but vulnerable hands, implied odds are even more crucial in Short Deck. You can often call with draws that don’t have direct pot odds, knowing that if you hit, you’ll likely stack your opponent or win a significant pot. Deep stack play amplifies the importance of implied odds.
Practical Application: Strategy in Action
Pre-flop Strategy: Aggression and Position
Short Deck is an aggressive game. Open-raising, 3-betting, and 4-betting are more frequent due to compressed equities and the desire to build pots with strong hands or capitalize on high-equity draws.
Opening Ranges
Your opening range should be wider than in NLHE, but still positionally aware. Generally, you can open all pairs, suited connectors, and many Axs/Kxs/Qxs hands.
| Position | Example Opening Range | Reasoning |
|---|---|---|
| UTG (Under the Gun) | TT+, AKo+, KQs+, AJs+, T9s+, 98s+ | Stronger hands for multi-way action; fewer people to act behind you. |
| MP (Middle Position) | 88+, AQo+, KJo+, Axs+, T8s+, 97s+ | Slightly wider, still focusing on strong pairs and high-equity suited hands. |
| CO (Cutoff) | 66+, ATo+, KTo+, QJo+, any Ax suited, Kxs suited, Qxs suited, any suited connectors (67s+) | Significant widening due to fewer players to act. High playability draws are key. |
| BTN (Button) | Any pair (66+), any suited Ax, Kx, Qx, Jx, most suited connectors (67s+), most Broadways | Widest range, leveraging position post-flop. Focus on hands with good potential. |
| SB (Small Blind) | Tighten up from BTN but still aggressive. 3-betting or folding is often preferred. | No position post-flop, so prefer strong hands or high-equity re-raises. |
Remember, these are starting points. Adjust based on table dynamics, opponent tendencies, and stack depths.
3-Betting and Calling
- Value 3-bets: With hands like AA, KK, QQ, AKs, you want to build a pot and narrow the field.
- Bluff 3-bets: Suited aces (e.g., A7s, A8s) and small/medium suited connectors (e.g., 87s, T9s) make excellent 3-bet bluffs. They have good equity when called and often hit strong draws.
- Calling: With deep stacks, calling raises with suited connectors and small pairs for set mining is often profitable due to high implied odds. Be cautious with weak offsuit broadway hands like KJo or QTo, as their equity is not as high as in NLHE without hitting hard.
Post-flop Strategy: Navigating the Board
C-betting (Continuation Betting)
C-betting frequencies tend to be lower in Short Deck than in NLHE, especially on wet boards. Why?
- Fewer “Dry” Boards: With more connected and suited cards, boards are often very coordinated.
- Higher Equity Draws: Opponents hit draws more often and have higher equity with them, making them less likely to fold.
Therefore, c-bet less frequently on boards that connect strongly with your opponent’s range (e.g., 9TJs, 678h). C-bet more aggressively on drier boards where you likely have the best hand (e.g., AAT, K66). Size your bets carefully: smaller bets for information or to protect a marginal lead, larger bets for value or strong semi-bluffs.
Check-raising and Bluffing
Check-raising is a powerful tool in Short Deck. You can do it for value with strong hands (sets, straights, flushes) or as a semi-bluff with strong draws (combo draws, nut flush draws, OESDs). Given the high equities of draws, semi-bluffing is often more effective than pure bluffing.
Value Betting and Relative Hand Strength
Always consider the relative strength of your hand. A top pair in Short Deck is much more vulnerable than in NLHE. If you have a set, a flush or straight might be out there. If you have a straight, a flush might be out there. Don’t slow play monsters too often; get value while you can, but also be prepared to fold strong hands if the board gets scary and your opponent shows significant strength. Remember: Flush > Full House!
Hand Examples: Putting Theory into Practice
Hand Example 1: Set Mining vs. Premium Pair (Cash Game, 100 ante effective stacks)
Pre-flop: Hero (BTN) has 8♦8♯. Villain (UTG) opens for 3 antes. Folds to Hero. Hero calls 3 antes. Blinds fold.
- Analysis: Hero calls with 88 for set value. UTG’s range is strong (TT+, AKs+, KQs+).
Flop: A♦9♯8♦ (Pot: 7.5 antes)
UTG bets 5 antes. Hero?
- Analysis: Hero flops a set of eights, a monster hand. UTG’s bet represents strong value (AA, ATs, AKo). However, the board is dangerous. A98 with two diamonds means there are straight draws (JT, 7T) and flush draws (any two diamonds) out there.
- Hero’s Decision: Raise. Raising for value is crucial here. You want to get chips in against hands like AA, AKs, ATs. Also, you protect against draws.
- Action: Hero raises to 15 antes. UTG calls. (Pot: 37.5 antes)
Turn: T♦
UTG checks. Hero?
- Analysis: The Ten of Diamonds is a scary card. It completes a straight for JT, and opens up many flush draws. If UTG has a flush draw, they just got it. If they have JT, they hit the nuts. However, if they have AA or AT, they might be checking to induce or because they’re scared.
- Outs for UTG’s range: If UTG has JT, they have the nut straight. If they have a diamond flush draw (e.g., K♦Q♦), they just hit.
- Hero’s outs: Hero’s set is vulnerable. Hero has a full house draw if another 8, A, 9, or T appears.
- Hero’s Decision: Bet again for value and protection. A check from UTG can be a trap or weakness. Betting allows Hero to extract more from AA, ATs, and charge draws. Given the scary card, a larger bet is warranted.
- Action: Hero bets 25 antes. UTG calls. (Pot: 87.5 antes)
River: 8♥
UTG checks. Hero?
- Analysis: Hero hits a quads! The nut hand. The only way to lose is if UTG also has quads (unlikely unless they had pocket 8s, which they didn’t call pre-flop), or if they had a straight flush (also extremely unlikely).
- Hero’s Decision: Shove. Get all remaining chips in.
- Action: Hero shoves remaining 57 antes. UTG sighs and calls with A♯A♦.
- Result: Hero wins a huge pot with quads against AA, which became a full house on the river. This highlights the volatility and how quickly equities can shift.
Hand Example 2: Navigating a Combo Draw (Tournament, Mid-stages, 50BB effective stacks)
Pre-flop: Hero (CO) has K♦J♦. UTG opens for 2.5BB. MP calls 2.5BB. Hero calls 2.5BB. Blinds fold.
- Analysis: Hero calls with KJo, a strong suited connector, for its high playability and implied odds. UTG and MP ranges are decent.
Flop: T♦9♦8♯ (Pot: 8.5BB)
UTG checks. MP bets 5BB. Hero?
- Analysis: Hero flops an open-ended straight draw (Q, 7) and a nut flush draw (any diamond). This is a strong combo draw with 5 straight outs (3 Qs, 2 7s) and 9 flush outs, for a total of 14 outs.
- Hero’s equity (approx.): ~60% against a single pair.
- Pot odds: MP bets 5BB into 8.5BB. Hero needs to call 5BB to win 13.5BB. Pot odds are 13.5:5 or 2.7:1 (27% equity needed). Hero has well over that.
- Hero’s Decision: Raise. A check-raise or raise here maximizes fold equity against MP’s range (which could be a strong pair or a weaker draw) and builds the pot for when you hit. It’s a strong semi-bluff.
- Action: Hero raises to 18BB. UTG folds. MP shoves all-in for 47.5BB total. Hero?
Hero vs. MP (MP had QQ)
- Analysis: MP’s shove means they have a strong hand (likely sets or overpairs like QQ, KK, AA). Hero’s combo draw has huge equity.
- Equity: Hero’s KJ♦ vs. QQ on T♦9♦8♯: Hero has approx. 58-60% equity.
- Hero’s Decision: Call. You’re getting excellent pot odds (47.5BB to win (8.5+5+18+47.5) = 79BB total pot). Your equity is >50%, making this a very profitable call.
- Action: Hero calls. Board runs out 7♦ on the turn. Hero hits the flush. MP shows QQ.
- Result: Hero wins the pot. This demonstrates the power of combo draws in Short Deck and the importance of recognizing high-equity situations.
Common Mistakes and How to Avoid Them
- Overvaluing Top Pair/Top Kicker: In NLHE, TP/TK is often a strong hand. In Short Deck, it’s highly vulnerable. With the increased frequency of sets, straights, and flushes, a single pair (even with an Ace kicker) is often no more than a bluff catcher or a thin value bet on a dry board.
How to avoid: Be prepared to fold TP/TK on aggressive turns or rivers on wet boards. Focus on having redraws or being pot-committed. - Incorrectly Calculating Outs and Pot Odds: Relying on NLHE math for draws will lead to significant errors. The “Rule of 2 and 4” does not apply.
How to avoid: Memorize the approximate probabilities for common Short Deck draws (refer to our table above). Always recount your outs carefully, especially for straights. - Playing Too Passively with Strong Draws: Sitting back and calling with a nut flush draw or an OESD misses crucial fold equity and fails to build the pot when you have significant equity.
How to avoid: Be aggressive with your high-equity draws. Semi-bluffing (raising with a draw) is a powerful move in Short Deck. It gives you two ways to win: by making your opponent fold, or by hitting your draw. - Ignoring Position: While equities are compressed, position remains king. Being in position allows you to control the pot, gather information, and make more accurate decisions.
How to avoid: Play tighter from early position and much wider from late position. Utilize your positional advantage to check-raise, float, and value bet more effectively. - Not Adjusting to Opponent Tendencies: Short Deck is a newer game for many, and opponents will have exploitable leaks. Some might overvalue their top pairs, others might chase every draw.
How to avoid: Pay attention to your opponents. If they fold too often to c-bets, c-bet more. If they call too much with weak draws, value bet aggressively when you have a strong hand.
Advanced Considerations
GTO vs. Exploitative Adjustments
While understanding GTO (Game Theory Optimal) principles provides a solid foundation for balanced ranges and optimal play, poker is fundamentally about exploiting your opponents. Short Deck, being a newer and more dynamic game, presents ample opportunities for exploitative adjustments.
- Against Weak-Tight Players: These players fold too much. You can widen your opening and 3-betting ranges, and increase your c-betting frequency, especially on turns. Target pots where they show weakness.
- Against Calling Stations: These players call too much with marginal hands and draws. Value bet relentlessly with your strong hands. Thinner value bets become profitable. Reduce your bluffing frequency, as they won’t fold.
- Against Aggressive Maniacs: These players raise and bet too much. Tighten your pre-flop ranges and let them hang themselves. Look for spots to trap them with strong hands or re-raise their light bets with high-equity draws. Don’t be afraid to flat call to keep them in the pot and let them bluff into you.
The key is to use GTO as your baseline, ensuring your strategy is robust, but then continuously observe and adapt to the specific tendencies of your tablemates.
Stack-to-Pot Ratio (SPR) in Short Deck
SPR is a critical concept in NLHE, and it’s even more so in Short Deck due to the increased frequency of multi-way pots and strong draws. With deeper stacks, implied odds become more pronounced, favoring hands with high potential (suited connectors, small pairs for sets). With shallower stacks, the game becomes more about pushing small edges and getting all-in with perceived equity. Knowing your SPR helps you plan future streets and determine commitment points.
Tournament Strategy (Briefly)
While Short Deck is predominantly a cash game format, tournaments do exist. In a tournament setting, ICM (Independent Chip Model) considerations become relevant as you approach the bubble or final table. Short Deck tournament play often involves even higher variance. Short-stack strategies will lean heavily on pushing pre-flop with hands that have good equity, like any pair, Ax suited, and strong suited connectors. Understanding when to risk your stack for a double-up versus playing cautiously to ladder up becomes critical.
Bankroll Management
The high variance inherent in Short Deck, driven by compressed equities and frequent all-ins with high equity (often 60/40 or 55/45 situations), necessitates a robust bankroll. A general guideline would be to have at least 100-200 buy-ins for the stakes you play, especially when starting out. This cushion will help you weather the inevitable downswings and allow you to play your A-game without financial pressure.
Practice Exercises or Scenarios
Put your new Short Deck knowledge to the test! Analyze these scenarios:
Scenario 1: Defending a Button Open
You are in the Big Blind with J♯T♯. Effective stacks are 100 antes. The Button opens for 3 antes. Everyone else folds. You call.
Flop: Q♯9♯8♦. Pot is 6.5 antes.
You check. The Button bets 4 antes.
Question: What is your optimal play? Justify your decision with pot odds, equity, and range analysis.
Scenario 2: Aggression with a Strong Draw
You are in the Cutoff with A♦6♦. Effective stacks are 100 antes. UTG opens for 3 antes. MP calls 3 antes. You call 3 antes. Button and blinds fold.
Flop: K♦9♦7♯. Pot is 10.5 antes.
UTG checks. MP bets 7 antes.
Question: What should be your move? Call, raise, or fold? Explain your reasoning, considering implied odds and potential draws.
Scenario 3: Facing Heavy Action on the Turn
You are UTG with K♯K♦. Effective stacks are 100 antes. You open for 3 antes. CO calls 3 antes. Button and blinds fold.
Flop: Q♦J♦7♯. Pot is 7.5 antes.
You c-bet 5 antes. CO calls.
Turn: T♦. Pot is 17.5 antes.
You check. CO bets 12 antes.
Question: What is your decision on the turn? What hands could CO have that beat you? What are your outs if you’re behind? Should you consider folding, calling, or raising?
Short Deck Poker FAQ
- Is Short Deck harder than NLHE?
It’s different, not necessarily harder. The math is simpler (fewer cards), but the hand values and strategic adjustments require a complete mental reset. It can be harder to adjust initially but highly rewarding once mastered. - What’s the biggest difference in hand rankings?
The fundamental difference is that a Flush beats a Full House. This impacts how you play draws and make decisions on the river. - Are suited connectors stronger in Short Deck?
Yes, significantly. Due to the reduced deck, the probability of hitting a straight or flush with a suited connector is much higher than in NLHE, giving them excellent implied odds. - What’s a good starting bankroll for Short Deck?
Due to the higher variance, a larger bankroll is recommended. For cash games, 100-200 buy-ins is a good starting point. For example, if playing 1 ante games, have 100-200 antes. - How do you calculate pot odds in Short Deck?
The “Rule of 2 and 4” from NLHE is inaccurate. Instead, use the exact outs (e.g., 9 for a flush draw from flop to turn is ~25%, from flop to river ~45%). Always divide the amount to call by the total pot size after your call. - Should I play more aggressively or passively in Short Deck?
Generally, aggression is rewarded in Short Deck. Compressed equities mean more players will have decent hands, and aggression allows you to build the pot when you’re strong or gain fold equity when semi-bluffing with high-equity draws. - What software can I use to study Short Deck?
While dedicated Short Deck solvers are still developing, tools like Flopzilla Pro (with a 6+ mod), Power-Equilab, and other equity calculators can help analyze hand vs. hand or hand vs. range equities. Reviewing hand histories from your tracking software (#affiliate-link) is also crucial. - Are there any “secret” Short Deck hands?
While not “secret,” hands like A6s (Ace-suited low straight potential) and double-suited rundown connectors (e.g., JTs98 double-suited) become incredibly powerful due to their high equity and multi-draw potential.
Conclusion: Master the 36-Card Deck
Short Deck (6+) Hold’em is a fascinating and complex variant that rewards aggressive, adaptable, and mathematically astute players. Its unique deck composition and hand ranking changes create a high-variance, action-packed environment where strategic depth truly shines. By internalizing the altered probabilities, understanding the shift in hand values, and mastering the art of aggression with high-equity draws, you can transform your game and find significant edges.
