I play with my wife a lot. But also been playing in the computer for ages with the chessmaster series.
Problem is I can't concentrate on the screen the same way I do on the real thing. I tried several table setups (2d, 3d, perspective) and even change the angle of the board. Currently I rank 1380 with chessmaster but I know I can do much better. I lose many games by sheer distraction and have trouble focusing; something that doesn't happen while playing with my wife on a real board. Strange... when considering I can abstract easily enough to concentrate myself while coding.
Of those of you who play, did you have/had the same problem? Did you find a setup you are more comfortable with?
