	I remember reading somewhere (possibly years ago) that chess
	Grandmasters did not gain their advantage over lesser players
	by being able to look more moves ahead than them (I think they
	used only look 3 or 4 moves ahead), but by the fact that they
	could eliminate all the "useless" moves from any position, and
	so have more time to concentrate on possibly useful moves.

	I seem to remember that this process was so unconcious that when
	these useless moves were pointed out to them they didn't reply
	that they had seen them and realised that they were no good, but
	that those moves had never even occured to them.

	Does this ring a bell with anyone? If so, I'd really appreciate
	the reference.

	Thanks in advance.

	John
