paul morphy, he made beating masters look like taking candy from a little kid
Since morphy died in the late 1800s and terms like master and grandmaster wern't around until the early 1900s I'm not sure what you mean. Sure he beat everyone, but there were no chess pros back then.
Surely if there had been stronger players in Morphy's time we would know how strong he was. Like Alekhine said, Morphy was born too early.
1. Fischer (Fischer had everything in my opinion. Enormous talent. Kasparov also said when Fischer died that Fischer probably was the greatest talent in the history of chess. Kasparov also said Fischer was a real "warrior").
2. Morphy and the lazy Capablanca! (Cant separate them)
3. Kasparov
4. Alekhine
5. Tal
6. Spassky (very talented He preferred doing other thing than training chess..he was VERY LAZY but he lived on his talent.)
7 . Anand
8. Karpov
9. Kramnik
10. Steinitz
I chose Fischer
I exclude Emanuel Lasker despite that he was worldchamp for 27 years . He would simply be defeated by all the above mentioned players in a match. I am sure (Lasker defeated Steinitz but Steinitz was over the hill and far from his peak when he faced Lasker.Steinitz also had mental problems). Reshevsky could very well be on this list. He was really a prodigy. He didnt care too much about theory. He just sat down and played sound positional chess and feared no one over the board. He was also a fantastic fighter. A last note : Maybe we can put Carlsen and Nakamura on this list in the future...God knows.
