Yes. That is a simple question.
is Magnus the greatest endgame player of all time
Fischer was a pretty phenomenal endgame player. I think they're about equally great in that phase of the game.
I know he has a history of being a very very strong endgame player, but show me something like Karpov-Kasparov '84 or anything nearing any one of Fischer's knight runs around the entire board then we'll talk greatest of all time.
He one won endgame today that could have been a forced draw with accurate play from Anand. Everybody calm down.
simple question?
