Black won 9 games and White won 5 game.

Players

AyaMC, LeelaX and Zen19X registered. I added the very much weaker gnugo3pt8, to avoid a need for byes.

Results

Zen19X won all its games: three with LeelaX, two each with AyaMC and gnugo3pt8. LeelaX and AyaMC played each other twice, each winning one game as black. LeelaX beat gnugo3pt8 three times, AyaMC beat it twice.

Thus the final scores were Zen19X 7, LeelaX 4, AtaMC 3, gnugo3pt8 0.

Annual points

Players receive points for the 2016 Annual KGS Bot Championship as follows:

Zen8
Leela5
Aya3
GNU Go2

As I have remarked in these pages before, the system used is good at identifying the best player, but much worse at identifying the second-best. The results of this event do nothing to suggest that either LeelaX or AyaMC is better than the other.
