Players

Six players registered, four for the Formal division and two for the less demanding Open division.

Results

Play in the Formal division proceeded normally.

However, we were all surprised to see that the Open division had been set up to use 9×9 boards, but with the correct 29 minutes each. This was my fault. I apologise, particularly to Katsuki Ohto, the creator of JulieBot, and to Gonçalo Mendes Ferreira, the creator of matilda.

JulieBot was unaware that the boardsize was different from what it expected, and tried to play at q16, which was rejected by the server. So play was impossible.

I cannot alter the setting of a KGS tournament once it has started. I could have created a new tournament starting a few minutes later with the correct settings; but with the 9×9 tournament still running, the bots would not have known which tournament to join. I cannot close the 9×9 tournament while it is still running. I could have removed both bots from the 9×9 tournament, but this would have left a tournament with fewer than two players, and I knew from previous experience that when the KGS tournament software needs to choose the pairings in a tournament with fewer than two players, it hangs, bringing all ongoing tournaments to a stop.
