try playing chess on a board on which you can see only your peices/only the opponents peices while he played on another hidden board on the computer or something, and then move on...
wow, that's actualy a good advice! never played blindfold in my life...
This is the first few moves of my first attempt at playing without viewing the board. As you can see, I get myself into trouble. I gave up and started looking at the board after this, but still couldn't salvage the game. I plan on trying again though.
