A single hand at the Poker Masters has reopened one of tournament poker's oldest arguments: are you obliged to bust a short stack on the bubble? At Event #4, a $10,500 No-Limit Hold'em tournament, Clemen Deng had the chance to eliminate Joey Weissman and did not. A recreational player called it disrespectful. A high-stakes regular called it simply how the game is played now. Both are describing the same hand, and both have a point.
This article walks through what happened, why the maths favoured Deng, and what everyday players should take away. If you have followed our coverage of Vitalijs Zavorotnijs winning Event 4, this is the story behind the story.
The Hand
According to PokerNews, 13 players remained with 12 paid. Blinds were 15,000/30,000. Weissman, on the button, raised to 180,000 with A♠K♠, leaving himself just 10,000 behind. Deng, in the big blind with roughly 1.6 million chips, called with a small pair rather than shoving over the top. The board ran out 9, 8, 4, 10, J, and both players checked it down. Deng's pair held, he won the pot, and Weissman was left with one-third of a big blind.
Why does that matter? Because Deng could have forced the issue. By calling and checking down, he left Weissman alive with a sliver of chips that almost guaranteed Weissman would be unable to play any real poker but would still occupy a seat, and a place in the money bubble.
The Criticism
John Krpan, a recreational player in the field, said Deng had "disrespected the game" by not eliminating Weissman. Deng's reply was that it was "part of my strategy." Krpan later said he would stop playing "because you're disrespecting the game."
It is an understandable reaction. Most players learn tournament poker with an unwritten rule: when someone is nearly out, finish them. It feels like the natural thing to do, and refusing to take the chips feels like toying with them. If your table has ever been stuck on a bubble for ten minutes while someone folds their way around, you know how frustrating it can be.
The Defence
Nick Palma, who was not in the hand, argued that this is how modern tournament poker works. His reasoning, as relayed by PokerNews, is that Deng's goal was to keep the other short stacks frozen so he could keep raising and pressure the bubble. In Palma's view, Deng was not disrespecting anyone.
That defence rests on ICM, the Independent Chip Model, which converts chip stacks into real-money equity. The short stacks at the table did not want to risk their tournaments until Weissman busted and they all locked up the min-cash. As long as Weissman remained alive with a handful of chips, those players would fold hand after hand rather than gamble. That gave Deng, the big stack, a steady supply of free chips: he could raise nearly any two cards and expect folds. The longer the bubble lasted, the more he profited. PokerNews notes that the big stack benefits from the bubble lasting as long as possible.
What the Numbers Imply
Think about the alternative. If Deng shoves or otherwise forces Weissman to commit his last 10,000, Weissman is almost certainly dead and the bubble bursts. The short stacks then relax, stop folding every hand, and start taking risks. Deng loses his leverage. Keeping Weissman alive costs Deng very little (the pot was small and Weissman's remaining chips were negligible) and preserves a pressure environment where other players are weak.
This is not cheating, collusion or angle-shooting. Everything Deng did was within the rules. It is a strategic choice that happens to look unusual to players who have not studied bubble dynamics. As we explain in our no-bubble tournament strategy guide, the money bubble creates a distinct phase where stack size matters more than cards.
The One-Chip Move
PokerNews says that the "one-chip move" has become common in high rollers over the past couple of years. Short stacks also use it: they leave a chip behind before a big pay jump so they can fold subsequent hands without putting in more money. The article says this works best from the button.
Here is how the logic works. Suppose you raise all but one chip. If the big blind folds, you win the pot. If someone calls, you can check down and still preserve a sliver of your stack. Because you still have chips, you cannot be blinded out of the hand immediately, and you retain the right to fold. In effect you are buying time. Weissman's 10,000 remaining chips did exactly that.
The Outcome
Weissman's sliver proved valuable. He built his stack to roughly 190,000 and avoided the bubble, which instead fell on Adrian Mateos. Krpan lost a race straight after the bubble burst and finished 12th for $20,000. Weissman finished ninth for $24,000. Deng went on to finish runner-up to Zavorotnijs and collected $144,000.
You can see why the story resonates. The "disrespected" player made the money, the critic made the money, and the player who played the unpopular line finished second. Of course, one hand cannot prove a strategy correct, but it illustrates why top players are comfortable with the approach.
Etiquette vs Equity
There is a real tension between etiquette and equity. Poker rooms rely on recreational players who enjoy the game and have a good time. Slow-rolling, needless delays and angle-shooting damage the atmosphere. Is declining to bust a short stack in the same category? Most strategists would say no, since there is no rule requiring it, no deception involved and no abuse of the opponent's time. Still, the reaction from Krpan shows that perceived fairness matters, and tournament organisers know that a satisfied amateur is worth far more than a few extra chips.
If you play for fun, you can reasonably choose to play the "traditional" way. If you play for profit, understand that the maths strongly supports exploiting bubble dynamics. Neither approach is wrong, but be honest about which game you are playing.
What This Means for Players
Here are practical takeaways:
- Study ICM before the bubble. Use the ICM explainer and practice with solver-based tools. Knowing when a call is -EV in dollars even though it is +EV in chips is crucial.
- Expect short-stack tricks. If the bubble is near and you are short, consider the one-chip move from the button, but only if the rules in your tournament allow checking down.
- Don't take it personally. Big stacks apply pressure because the maths says to, not because they want to humiliate you.
- Protect your bankroll. Bubble variance is brutal. Our bankroll management guide and the bubble variance lessons from Mateos's hat-trick cover how to ride the swings.
You can also compare how different formats treat the bubble in our cash games vs tournaments piece. Cash games have no bubble, which is why some players find them more honest.
The Bottom Line
Clemen Deng did not break any rules, and he did not harm Joey Weissman: the short stack made the money, and Deng made a deep run. Whether you consider his decision unsportsmanlike depends on your view of poker, as a gentleman's pastime or as a competitive discipline. At a $10,500 buy-in with a Purple Jacket on the line, the second view is likely to prevail, and the one-chip bubble play is going to become more, not less, common.
