I don't know anything about chess, but I think this rule basically applies to any game played at a high level. I used to be a top 10 player in a 90's online game and I often used anonymous accounts (smurf accounts) for fun. One day as a joke I attempted a playing style that mimicked a complete novice (just moving the mouse with no keyboard input) and it was so effective it became a normal part of my repertoire. Eventually others took notice and it just became part of the game.
