In chapter 11 of Ace on the River, Barry Greenstein explains that technical poker skill alone is not enough—long-term success depends on mastering game selection, timing, discipline, and money management.
Why Playing Well Is Not the Same as Making Money
Greenstein begins by noting that modern players often have strong technical knowledge due to books, software, and online poker. As a result, the gap in how hands are played has narrowed, even between middle-limit and high-limit games. However, many technically skilled players fail to move up because they lack the practical skills required to actually extract money and protect profits.
The Importance of Game Selection
Using an analogy from another competitive activity, Greenstein emphasizes that making money means choosing opponents you can beat, not proving yourself against stronger ones. Poker differs from many games because players of widely different abilities freely compete against each other.
Rather than measuring success by correct starting-hand selection alone, he advises focusing on who you are playing against. A game with one very weak player—or several players who are clearly worse than you—is a profitable game, regardless of how strong the best players at the table may be.
Evaluating Players, Not Just Hands
Greenstein points out that many players misjudge game quality by focusing on visible mistakes like poor starting hands. Stronger evaluators look deeper, noticing betting skill, pressure, timing, and how opponents react emotionally. A player who appears sloppy may still be dangerous if they manipulate others effectively.
When assessing a game, Greenstein ignores the best players and concentrates on the weakest ones, since that is where the money comes from.
Timing and Scheduling Your Play
Knowing when to play is as important as knowing where. Some games are best entered early to secure seats next to weak players, while others become most profitable later when players are tired, frustrated, or trying to recover losses.
Greenstein asks a key question: why settle for a small edge when patience can give you a large one—especially after accounting for rake and time costs. He notes that only a small fraction of players earn enough to cover expenses, let alone bad habits.
Understanding Your True Edge
He discusses advantage in terms of action and expectation. Even a modest percentage edge can be meaningful over time, but variance is large. This reality makes discipline essential, especially during downswings. When results are poor, moving down to a softer game is often the correct professional decision—not a failure.
Playing Marginal Games Strategically
Sometimes playing a tough or marginal game makes sense for practice or because it may improve later if weaker players join or stronger players tire. Greenstein advises using these situations carefully and consciously, not out of ego.
Versatility Across Poker Variants
To avoid missing good opportunities, serious players should become competent in all common poker formats. In mixed games, there are always players with weaknesses in certain variants. Strategic voting on which games to play should be based on relative advantage, not personal preference.
Access, Location, and Networking
Living close to games and maintaining good relationships with casino staff and hosts increases access to rare, highly profitable situations. A timely phone call can be worth a great deal, and Greenstein stresses rewarding those who help you get into good games.
Managing Fatigue and Opponent Tilt
Greenstein explains that tired players—especially those stuck and chasing losses—are prime targets. He prefers to leave when fatigued and return rested, or arrive late when others are worn down.
He introduces the idea of a player’s “steam point,” the level of loss that causes emotional breakdown. Knowing this helps determine when to stay, when to quit, and how to adjust strategy against opponents on tilt.
Avoiding Asymmetric Risk
A central rule is to avoid situations where you can lose a lot but win very little. Chasing losses, playing for round numbers, or entering games with illegal buy-ins creates unnecessary danger. Greenstein strongly discourages partnerships, as they distort decision-making and increase pressure.
When (and When Not) to Quit
Greenstein argues against quitting at peak wins except in specific circumstances, such as protecting the game, credit risk, or exhaustion. Staying while the game is excellent—even for very long sessions—is often correct. Leaving too early relieves pressure on opponents and reduces long-term profits.
Thinking Long Term About Opportunity
The chapter closes with a reminder that great games are temporary. Poker ecosystems depend on a small number of key players, and profitable situations eventually disappear. Greenstein urges players to maximize opportunity while it exists, understanding that periods of abundance are often followed by scarcity.
Core Message of the Chapter
Making money in poker is about patience, selectivity, endurance, and judgment. Greenstein emphasizes that the real edge comes not from knowing the game, but from knowing when, where, and against whom to play—and having the discipline to act on that knowledge.
