Hi, the last version of gothic is available at http://www.irisa.fr/prive/Tanguy.Urvoy/gnugo/gothic-0.6.5.tgz
This version is still alpha but promissing: - you can already play against gnugo. - you can send GTP commands during the game via GTP shell. - you can undo moves. - gothic can show you the dragons and their status during the game (red for dead, green for alive, orange for critical). ...
For those who do not have Qt 2.3 installed on their computer a screenshot is available here: http://www.irisa.fr/prive/Tanguy.Urvoy/gnugo/screenshot.jpg
There are some problems: Gothic is a bit too slow. Because GTP commands are synchrones gothic must wait the answer of the engine before doing anything, we cannot "see the engine at work". Why not consider asynchrone GTP commands ?
Please try it and send us comments and bug reports.
