In chapter 4 of Ace on the River, Barry Greenstein examines superstition in poker, explaining why it is so common, how it distorts thinking about luck and skill, and when—paradoxically—it can still influence results.
Luck vs. Skill in Poker Culture
Greenstein begins by noting how poker conversations change depending on recent outcomes. Winning streaks are labeled as unstoppable luck, while losses are framed as poor judgment or staying too long. Although luck is undeniably central to poker—allowing beginners to beat experts in single hands or short sessions—players often exaggerate its role and overlook long-term skill.
How Superstition Replaces Analysis
Rather than asking how a player improved their strategy, poker culture tends to focus on lifestyle changes or mystical explanations for success or failure. This mindset encourages players to attribute outcomes to forces outside their control instead of examining decision-making quality.
Common Superstitious Behaviors
Greenstein lists many rituals players use in an attempt to “change their luck,” such as:
-
Switching decks or cards
-
Changing seats or table positions
-
Sitting out hands after losing
-
Refusing to break up “lucky” chips
He points out that players often credit these actions only when results improve, ignoring the possibility that wins would have occurred anyway.
Self-Fulfilling Negative Cycles
Superstitions can actively worsen results. A player who believes a dealer is unlucky may play too cautiously, allowing opponents to exploit them. Others play distracted or recklessly due to external stress, then blame losses on bad luck rather than their altered behavior.
Why “Lucky” Players Stay Lucky
Greenstein explains that apparent luck often persists because strong players continue making good decisions, while opponents tilt and play poorly when losing. This creates the illusion that one player’s fortune is extraordinary, when it is actually reinforced by others’ mistakes.
Misunderstanding Probability
After unusual events occur, players frequently ask about the odds—without realizing that rare outcomes are guaranteed to happen sometimes. Asking about probability after the fact leads people to believe something unnatural or conspiratorial occurred, even though randomness naturally produces unlikely patterns.
When Superstition Can Be Useful
Although he is skeptical of superstition, Greenstein acknowledges a practical exception: if a belief causes a player to quit a bad game, leave while losing, or avoid an environment where results are consistently poor, it may have real value. Whether the cause is psychological, situational, or even cheating, the outcome—reducing losses—can still be beneficial.
A Rational View of Irrational Beliefs
Greenstein closes with the idea that beliefs do not need to be logically true to influence behavior. If something encourages better decisions—such as stopping play under poor conditions—it can “work” regardless of whether the reasoning behind it is rational. The key is recognizing that results ultimately come from decisions and discipline, not magical forces.
