Nicely stated. In "Ace on the River," Barry Greenstein says that traits of winning players include being greedy and self-centered. Traits of losers include compassion. Poker is a predatory game: The strong eat the weak.

That's kind of a radical synopsis - Greenstein clearly doesn't go in for the "merciless assassin" ideal.

For example, Greenstein says several times in the book that a good player makes the "live ones" feel good about playing, so they'll play more, including quitting before you clean them out if need be.
