Black won 30 games and White won 38. MCark also lost four games by forfeit, after disconnecting from the server.

Players

Shortly before the deadline for entries, when six players had registered, I received an entry from 'stv', so I also included gnugo3pt8 to make the numbers even.

After the deadline, I received an entry from coldmilk. I chose to accept this as it would make the number of genuine players (i.e. not gnugo3pt8) even. Unfortunately, in my hurry to get it registered in time, I used the wrong name, "coldmilk" instead of "ColdmilkS" as specified. Fortunately, its operator also controls the "coldmilk" account on KGS, and was able to use that.

I have decided to shorten the deadline, from 30 minutes to 15. minutes before the start of play, but to enforce it rigorously in future. Fifteen minutes should be enough for me to cancel the tournament, create another one in its place, and re-register all the entrants, if something goes wrong.

Results

In round 1, coldmilk was about 30 seconds late for its game with HiraBot, after its operator had restarted it as explained above. It eventually lost the game.

Also in round 1, Orego12 was black, and played normally. This was the only game in which it played a stone on move 1.

In round 3, Orego12, as black against MCark, passed on move 1. MCark then passed, ending the game and winning by the komi. In every subsequent game in which it was black, Orego12 passed on move 1. Only MCark was smart enough to pass for an immediate sure win. HiraBot, NiceGo19N, and coldmilk all played stones, and eventually won their games.

In round 14, MCark lost on time to fuego13.

In round 15, MCark did not join its game with Orego12, and eventually lost on time. I later found that it was no longer connected to KGS. It also lost all its subsequent games on time. These games are shown as losses on Time in Orego12's game record, but as losses by Forfeit on the KGS web site, e.g. here.
