Black won 17 games and, White won 19. As almost all the results between any pair of players was the same, and as each pair alternated in colours as they played each other, this tells us very little.

Players

Four players registered.

Results

In round 13, Zen19X had its only loss, to AyaMC. This was a particularly difficult game to understand, with the centre of the board occupied by a large seki. AyaMC won by 1½ points, and a kibitzer suggested that it had thrown away a few points to obtain this minimal winning margin (as MC-based programs are often perceived by humans to do).
