If you want to flatten the numbers to more like common GURPS skill levels, treating a chess match as a best of 5 makes the ratio about 150.

Is there a way to more closely simulate actual play: the higher the skill of the players, the more likely they are to draw, and the higher the first-move advantage. Top level play sees about 60% draws and 60% of the rest white victories.
