Description

This report is unusually short, as I don't have much time to write it before going away on holiday. By the time I return, I shall have forgotten what I might have addded to it.

Thankfully, there was only one disputed game.

AyaBot is programmed to make its first four moves at random (though I assume in different corners). This is reasonable in 19x19 games; but in its round-three 9x9 game, as White against CrazyStone, its second move created the position shown. CrazyStone answered in the way recommended in books for beginners, and AyaBot got a very poor position, from which it was never able to recover.

Forfeited games

The only "forfeited" game was twinbot-StoneCrazy.sgf in the third round of the Open division. Other game records are available from the KGS pages: Formal Division. Open Division.
