Over the years I have played a few games of blindfold chess but never more than one game at a time. I have had some decent results , winning a game against an A class player and a win against a 2300 ( uscf ) player but with the 2300 we were both playing "blindfold" as we were playing in a car during a trip to a tournament together. I have founf that the most difficult opponents for me to play blindfold against are people who are not "book/tournament" players. They make moves which make no sense, fit no pattern/opening thus making is much more difficult to recall where everything is on the board.....leading to more frequent blunders for me....
My understanding of blindfold chess was that you were given a board and had a copy of all the moves that had been made? Is this incorrect?
I'm not sure how they play blindfold chess know, but this is how Tal played it http://www.youtube.com/watch?v=KEObwChS2O4
As long as you remember to take it off before popping out to the shops you're okay.
