Point taken top!
In retort I may quote (perhaps not verbatim) Santasiere: "Chess is not mathematics and cannot be reduced to A+B=C".
I like to use logical arguments when it comes to discussing variations, and certainly when it comes to books that give faulty analysis, when there is conflicting evidence.
I totally disagree with your sweeping statement about mathematicians. Is it based on that weary idea of matmematicians being dull because someone never understood maths and therefore anyone that does understand must be dull and boring and play dull and boring chess? Often I hear the same kind of argument about scientists and their social ineptitude.
Perhaps one could think that mathematicians like to play chess in a different ways. I, for one, prefer the good old fashioned romantic style with either colour. Just as I prefer brazilian football over german, 49ers throwing game over Dallas' pass and running game. Undeniably the german way of playing football is more logical than the erratic and unpredictable brazilian way. If you throw the ball in american football you also risk being intercepted and look stupid, which is really what it is about isn't it? No guts no glory!
As a scientist I can tell you that there is no such thing as a free lunch, unless you ask God to amend the 2nd law of thermodynamics.
IMHO the King's gambit is a logical opening. Is the exchange Slav a logical opening? Is it more logical than the King's Gambit. Why play 1.e4 if you want to win without incurring the risk of losing?
Countless chess players have searched for the free lunch. They prefer the comfy predictable maneouvering games where nothing unexpected happens and they win a technical rook endgame because the opponent gets bored and does something stupid.
Without psychoanalyzing anyone I think this trait roots in the archetypal fear of the unknown metamorphosed into a need to be in control.
