One of my dreams is that a team captain could set up the engine with selected books and strength so that team-players could train for the next match without the bother to create all the setup themself. He could of course also distribute settings by e-mail if all the players have interface by their own. >* the specification should be more precise in most points now > Yes, it's nice that the ponder issue is clear now. At first glance I could have wanted some words about commands out of order, eg. there seems to be some gui that use 'stop' just to be sure the engine doesn't run. > >At http://www.shredderchess.com you can download the specification of the >protocol as well as a GUI and an engine which are already supporting the new >protocol. GUI and engine are free for testing for 30 days. > First impression was good, though there was some (small) issues. Soundfiles? A copy from Shredder 6 seems to work. Helptext in german. Some minor issue with the new dgt-support (result event). I didn't get it to work in Chess Assistant (only 1-2 plies), even after registration. Maybe this is a little more serious since it only for analysis I need the full strength. Odd Gunnar
