Hello,
qGo, a relatively new SGF editor, is now able to act as an interface to play games with gnugo using GTP.
The project is still in an early stage and the release is a preview.
qGo allows you to: * play against gnugo (human vs computer) * undo moves * control and debug gnugo via GTP console * score games using qGos own scoring * guess the score using gnugo
I am sure it is anything but bugfree, but I managed to play a couple of games against gnugo without big problems. Handicap is currently not yet possible.
qGo is available at http://qgo.sourceforge.net/java/ Please note there is also a Qt version, this one does not have the GTP features (maybe somewhen in the future).
I have not seen GTP before, but I must say, it is very smooth and easy to use as programmer. I got the basic engine for playing done in a night. Don't want to think how long that had taken with GMP. Great work!
Peter
