Kasper wisely informed me that soccer tournament rules regarding points awarded (to defeat, draw, and victory) were revised some 20 years ago creating stronger incentives for aggressive play (3 points for victory instead of 2). That’s a wonderful example, which certainly managed to make the thesis section I’m writing on game sum types even more confusing.
But does anyone have a reference to this rule change? Someone know a good history of soccer rules? Or a few more details to help me google?
