I would lose on time, everytime, if listening to the cello suites while playing... :P
iPODs, smartphones and all sort of electronic devices (excluding some notation ones, and that not under the FIDE rules) are not allowed at the playing hall. Only handicapped players, e.g. blind people have the right to use certain equipment.
Better moves. And somehow the game feels profound. Like the game is the feelings and becomes the crescendo. Or Bach cello suites. If I play in another otb tourament would I be allowed to take an mp3 player and listen to my classical music during the play? Any rules on that?
