I've liked Bent Larsen since I read "Bent Larsen: Master of Counter-Attack" by Larsen (and Keene I think). Admittedly, Keene isn't great, but the games are!
I also like Kasparov because he's awesome and probably the greatest of all time.
Also Karpov coz his play is beautifully 'natural'.
I have one question to ask all of you chess.com users: Who is your
favorite chess player? My favorite is Magnus Carlsen mostly because
he became a grandmaster at the age of 13 and he is the number 1
chess player in the world. Those aren't really ethical reasons but it's
all I got for Magnus.
