“The marginal advantage embodies the notion that one cannot, and should not, try to “win big.” In a competitive setting, the strong player knows that his best opponents are unlikely to make many exploitable mistakes. As a result, the strong player knows that he must be content to play with just the slightest edge, an edge which is the equivalent to the marginal advantage. More importantly, a one-sided match ultimately carries as much weight as an epic struggle. After all, the match results only in a win or a loss; there are no “degrees” of winning. Therefore, at any given point in a game, the player must focus on making decisions that minimize his probability of losing the advantage, rather than on decisions that maximize his probability of gaining a greater advantage. In short, it is much more important to the expert player to not lose than it is to win big. Consequently, a regular winner plays to extend his lead in a very gradual, but very consistent manner.”
