A guy at a tournament told me a Fischer simul story.
He had played him 6 months before, and became his
college's organiser for a second simul. After the simul
Fischer said to him "do you remember your position on
move..." and started to set up the board, but not the one
just played (!) but the one 6 months before.

Yeah, Fischer played and practiced so much that the game and all of
its moves became instant recalling chunks of data to him. Much like a
computer programmer remembering an entire subroutine in one of his
huge programs of thousands and thousands of lines.
