He was only 60 years old. RIP      Feb-21-21 O Bernstein vs Nimzowitsch, 1914    CharlesSullivan: This is a very famous game: Chernev called it the "most brilliant drawn game ever played"; Martin Beheim called it "almost the ideal game of chess."

If your question is, How many (ill-defined) "better" moves ...      Sep-27-18 Fischer vs Spassky, 1972    CharlesSullivan: <Tiggler> < I would appreciate a bit more information on the total effort involved in his analysis, and about his hardware. > Tiggler, thanks for your comment.
