Indeed, I admitted it:) But I held off on the name change as I'm not certain it will go over well with the CTF Moderators. I'd like to come back with my name...CCC doesn't mind, but that's another chess game;-) It's interesting you brought up 13. a3! as it's a very key move early in the game and it crossed my mind as well. You would have to make sure books were off, as it's in opening books. I will test this move latter, but my hardware is S-L-O-W! Still, fast hardware may not be of much use as it is a positional move of the human kind as you say, (long range/planning), rather than the computer/program kind. Move 23. Bf6! although tactical, is also another good test move, so this game is rich for computer/program testing. Terry > >Anyway, this was indeed a great game and I'm glad that you brought it up. >Thanks.
