Some people think that there are too many draws in high-level chess (55% of games among players rated over 2500 end in draws, according to this Wikipedia article)
Over the years, various proposals have been made to reduce the frequency of draws, often involving tinkering with the rules of the game.
Clint Ballard has proposed an interesting change, not to the rules of the game, but to how the game is scored for purposes of determining rank in tournaments, so that players will have a much stronger incentive to play for a win. He’s putting his money where is mouth is, and sponsoring tournaments using his scoring system.
