This is for Douglas.
How to tell when a computer is being used:
Average, weak, or new players to the game should not be making great
moves.
I have seen it also. Several Yahoo! and POGO players, probably mostly
kids admitted they were using a computer against me. I know of two games
I lost to computers.
I also know of several others where I beat the computers.
It is against USCF Postal or email rules to use a computer during a game.
It is also against FICS. EWCCF,and CCLA rules to use a computer.
To play a game when neither player can use any help go to FICS. A free
site.
EWCCF: I do not know how the games work but I think it is similar to
FICS.
(I am a tournament director for EWCCF). But I do not play with EWCCF.
USCF and CCLA use email to play games.
It is not against USCF rules to use a book for a postal, email game.
Normally a book is for the opening moves. Chessbase.de has an online
Opening book also.
Or rather games. I do know of players using a database program for
Opening help also.
I do also.
But Midgame and endgame I depend solely on my learning and training.
Remember that most of these games mean nothing. I did not play chess in
nearly 30 years and wanted to get back into 'shape.'
Playing with a computer would have set me back. The reason, the computer
would have been doing the thinking for me.
All those players using a computer to play their games are cheating
themselves. They will never learn how to play good chess.
