I think Spassky is definitely the most underrated of the "great players". It seems like all the legends (Fischer, Kasparov, Karpov) have a very high opinion of him, and yet amateurs never give him the credit he is due because of the "Match of the Century". I was reading Yasser Seirawan's new book, "Chess Duels", at Barnes and Noble recently and he thinks Spassky is the 5th greatest player of all time. Of course, I couldn't say for sure if he's top 5 material, but he's definitely top 10. In the last top 10 thread he wasn't even mentioned... Personally I love his games.
