Cheat Sheet
Short Deck (6+) Rules & Key Differences
- 2s, 3s, 4s, and 5s are removed. The deck has only 36 cards.
- Flush Beats Full HouseBecause there are fewer cards of each suit (9 instead of 13), flushes are mathematically harder to hit than full houses.
- Ace as Low (A-6-7-8-9)Aces can still be high (T-J-Q-K-A) or low, making the lowest straight A-6-7-8-9.
- Straight Beats TripsIn this calculator, we follow the standard rule where Straights determine stronger hands than Three of a Kind. (Note: Some house rules differ).

Strategy Insight: Why Antes Matter
In Short Deck, every player posts an ante, and the Button posts double. This creates massive pot odds (e.g., 7:1 for UTG), making 'limping' standard and mathematically correct for many hands, unlike in NLH. However, open-raising often leads to playing out of position post-flop against the Button. Mastering this unique ante structure and balancing your limp vs. raise ranges is the key to Short Deck strategy.
Pocket Pairs Equity: NLH vs Short Deck
Pocket pairs lose value much faster in Short Deck due to the condensed range. The table below compares equity against a top 14% range.
| Hand | NLH Equity (%) | Short Deck Equity (%) |
|---|---|---|
| AA | 85% | 76% |
| KK | 73.5% | 60% |
| 67.5% | 52.5% | |
| JJ | 62.5% | 46.5% |
| TT | 58% | 43% |
| 99 | 53.5% | 40% |
| 88 | 50.5% | 38.5% |
| 77 | 47.5% | 36.5% |
| 66 | 45% | 34.5% |
Notice how quickly equity drops. In Short Deck, lower pocket pairs are significantly weaker than in NLH. Don't overvalue them!
Short Deck Strategy: 3 Basic Tips
Transitioning from NLH? Use these fundamental tips to adapt to the new math and dynamics.
1. Play Suited Hands & Pairs Aggressively
Flushes beat Full Houses in Short Deck, and Sets are harder to hit but extremely powerful. Their increased value justifies more aggressive play.
2. The Rule of 6 and 3
Calculate your equity easily. Multiply outs by 6 on the Flop and by 3 on the Turn. (e.g., OESD on Flop: 8 outs x 6 = 48% ≈ actual 45.5%).
3. Adapt Core NLH Concepts
Positional advantage is king. Play loose on the Button, defend wide from the Big Blind, and balance your 3-bet ranges. Your NLH intuition still applies, just with adjusted ranges.
