Spaasky as in Boris Spaasky, ex-World Champion, lost to Bobby Fischer in the 1972 World Championship. Fischer played Alekhine's Defense in their match and won, if I recall correctly.
I'll cast my vote for the Caro-Kann, but I'm biased. Really, really biased.
One thing makes me curious here.
Why do you want to settle for equality, there is no such thing in chess anyway the dynamics change with every move, you want a defence that recognises that.
