Quoting John Tromp <[email protected]>:
The fact that Zen won all its games, both with black and white,
means that most,
if not all competitors are far enough away from perfect play to to
make komi adjustments
unnecessary.
I think your argument only holds when a superior program plays a much
weaker program.
Programs of almost equal strength will play 1-1 almost every time.
With integral komi we would also get 1.5-0.5 results in addition
which improves discrimination. The majority of participants in a
tournament are usually close in strength. In the next tournament Zen
might not be superior anymore and then we could have a trouble even
finding a clear winner.
It is of course necessary to play 2 games with alternating colors no
matter what komi is used in 9x9 tournaments. Even with integral komi
one color might be favored because it may be harder to find perfect
play for that color.
