In my extended social circles, people often cite Dave Sirlin's "Playing to Win" on how one should play games citing the "scrub" chapter to justify any behavior allowed by the rules.
Sirlin's argument is that by having some concept of what's ok and what's "cheap", one becomes a scrub who sucks at the game. This didn't seem right at the time, and the more I've played games the less right it seems. In many games, the top players avoid "cheapness" and people who do "cheap moves" are generally bad.
