This match was played through a system by Hiroshi Yamashita that 
automatically reads the screen and sends mouse events, so that any GUI 
program can be connected to GTP. This system seems to be not 100% 
reliable, and does not handle any scoring protocol.

This is quoted from a mail by Hiroshi Yamashita to me after the match:

"
KCC and Crazy Stone played 20 games.

I listed as follows.

Crazy Stone has  14 wins and 5 losses.
One games stopped halfway, so I don't count this.
And I counted these two games to KCC win.

It failed to recognize stones. 323th black move was not real move.

KCC lost on time. But I think if KCC had time control, KCC could win.
211th move was K-2. (it did not play)

5-14 

I also attached Gnugo vs KCC result.

GnuGo is 3.7.10.
Ginsei Igo 7 is a latest version of KCC (Dec 2006)
Ginsei Igo 5 is 2004 version of KCC.

Ginsei Igo 7 is a same version that played against Crazy Stone.
