Some time ago, I referred to game theory with respect to standards of play. I can't remember exactly what I said, but it amounted to making the penalties for 'dirty' play greater than the benefits. That is, that players must feel that if they foul, they will lose out, as opposed to gaining an advantage. The job of the rule-set & ref, therefore, is to make it clear that this proposition (dirty play will cost goals, and lose you the game) holds.
I agreed with you then and I still agree with you now.
