The answer to 2) is clear: each player tries to maximize its winning
probability, so a large d is good, if a is negative and a small d is
good, if a is positive (if you have already subtracted the komi value).

Using a Gaussian curve with parameters a and d, one can integrate
over all positive values. However, the distribution will not be symmetric
in reality.
