Fischer and Capablanca both nodded to Morphy (which is all the more significant given the tendencies of the chess ego!):
"A popularly held theory about Paul Morphy is that if he returned to the chess world today and played our best contemporary players, he would come out the loser. Nothing is further from the truth. In a set match, Morphy would beat anybody alive today... Morphy was perhaps the most accurate chess player who ever lived. He had complete sight of the board and never blundered, in spite of the fact that he played quite rapidly, rarely taking more than five minutes to decide a move. Perhaps his only weakness was in closed games like the Dutch Defense. But even then, he was usually victorious because of his resourcefulness." ~ Bobby Fischer
"[I play in] the style of Morphy, they say, and if it is true that the goddess of fortune has endowed me with his talent, the result [of the match with Emanuel Lasker] will not be in doubt. The magnificent American master had the most extraordinary brain that anybody has ever had for chess. Technique, strategy, tactics, knowledge which is inconceivable for us; all that was possessed by Morphy fifty-four years ago." ~ José Raúl Capablanca
This how strong Capablanca, even when he was old and the young generation of top GMs; Capablanca still can play against the strongest young GM. Salo Flohr was a world champion contender and tie a match with Botvinnik and Capablanca beat him with no effort. Capablanca draws with ease against Botvinnik. Capablanca: 1 win, 5 draw and 1 lost and Botvinnik 1 win, 5 draw and 1 lost, tie score against a future world champion, let see if Carlsen can do the same.
