Excluding forfeited games, Black won 12 games and White won 8.

Players

Five players registered. To make the numbers even, I included gnugo3pt8.

Results

In round 1, ManyFaces1 was not present, and eventually lost on time to gnugo3pt8.

Also in round 1, CrazyStone, which had recently been recompiled to play 13×13, had difficulty playing. After seven minutes, it played its first move against Zen19X, but it made no more moves and also lost on time.

In round 2, ManyFaces1 was not present again, and lost on time to CrazyStone. After the round was over, I removed ManyFaces1 and gnugo3pt8 from the tournament, so as to have two interesting games each round, instead of (on average) 1⅕.
