Oops... Usually I have Many Faces play on-line using Japanese rules, since most people prefer them. I forgot to switch last night, so the engine was scoring Chinese, but the server was scoring Japanese, and that accounts for many of the losses.
Also, many of the games were played with 0.5 komi rather than 6.5, so they should be counted differently. So please ignore my previous email. Petr, did you check your games to make sure they are at 7.5 komi rather than 0.5?
