How quick you guys always are when it comes to "move X is better than move Y".
What exactly is your proof that Bxg6 is any better than cxb5? How many moves to
checkmate for Bxg6 and how many moves to checkmate for cxb5? Or how do you
define "move X is better than move Y" again?

Note: Please don't take this as a personal attack or something, because it's
not. :)
