Smyslov I like because he did not overestimate opening theory,rather believed in his natural powers on the board and was a big fighter until the endgame. In that way he beat the overprepared Botvinnik. It is sometimes said his games are very harmonious but I cannot discover anything more harmonious in them than in any other good game of a master. He played chess very long in his life keeping a good strenth throughout. Somewhat he is the counterpart of Morphy in this respect. I also like one line I read from him when he stated: Whether you win or loose, you have to bear it with the same calm and equal mind.
