Quit before round 2

Black won 17 games and White won 19.

Players and format

Six players registered. I also registered gnugo3pt8, in case it was needed to avoid byes.

When I ran gnugo3pt8, it gave the error messages

Unknown message type -105 for channel org.igoweb.igoweb.client.gtp.aj@7024d0fa
Unknown message type -105 for channel org.igoweb.igoweb.client.gtp.a@45fcb00e

which it had never done before. My guess is that this was caused by a recent change to the way the KGS server handles communications. It worried me slightly, but it seemed not to affect gnugo3pt8's play.

However Detlef Schnicker reported that his program oakfoam, playing as NiceGo19N, had produced a much longer error message, ending with "Normal disconnection from server." I therefore feared that NiceGo19N, and maybe also other entrants, would be unable to play, and I included gnugo3pt8 in the first round with the other six entrants, in case there was an odd number of working programs.

Fortunately, all six entrants were able to play by the time the tournament started, so I removed gnugo3pt8 after round 1.

Results

The tournament ran very smoothly, without any incident that needed my attention.

Irrelevant remarks

I was away from home, running this tournament on a laptop in a friend's house. I found that was unable to run CGOban. This surprised me; I have been careful not to install recent versions of Java. Fortunately I had a version of CGOban.h, the "hacked client" by Petr Baudi�, creator of pachi. This worked perfectly, apart form one small problem described below. I would like to thank Petr for providing this valuable resource for KGS users, which is proving more reliable than the official client.

The friends I was with complained about the "click" sounds of stones being played, so I wanted to turn these off, without turning off the ringing sound that would be played if anyone tried to chat to me. This ought to be easy, it's the same with CGOban.h as with CGOban, it's an option in "File" - "Set Preferences". However, the "Set Preferences" window is a dialog box, and so not resizable, and with CGOban.h its height is slightly greater than that of my laptop screen. This means that its "OK" button is off the bottom of the screen, and there is no obvious way of getting it on to the screen.

Eventually I found a way: use the dialog box to disable the stone clicks; go into the Windows Control Panel, Display, and set it to Portrait; use the mousepad to manoeuvre the now-sideways-working cursor (this is harder then it sounds) to the Control Panel's "Apply" button; manoeuvre it again to CGOban.h's Set preferences "OK" button; and finally back to the Control Panel, and use more mouse manoeuvring to get the screen back to landscape.

I learned later that there's a much simpler way to rotate the display on a Windows laptop. You do Ctrl-Alt-arrowkey, where the direction of the arrow key corresponds to the desired orientation of the display.
