Players

Ten players registered. We welcomed two new players to these events:

  • Ray, by Yuki Kobayashi, playing as Raybot
  • matilda, by Gonšalo Mendes Ferreira
  • Unfortunately, matilda had to withdraw.

    With nine players remaining, I entered GNU Go, to make the numbers even.

    Many Faces of Go entered, but did not connect to KGS before the end of round 1, so I removed it and GNU Go, leaving eight players.

    Results

    In round 1, AyaMC had a problem with its connection, and lost in time to GNU Go (which was playing as gnugo3pt8).

    In round 7, abakus lost its only game, to AyaMC.
