CHAPTER FOUR
Common Strategic Mistakes
(1)
Black loses when he allows the game to become focused on White's  Bishops and their dominating diagonals
(2)
For White, the biggest mistake is usually to lose control of e5
(3)
One of the principal causes for Black's downfall over the years is a premature exchange of pawns on d4
(4)
As in the Koltanowski 5.c3, Black should avoid an unfavorable change in the pawn structure when White plays dxc5 followed by e3-e4
(5)
It's often a mistake for Black to post his queen at c7 when White can favorably open the c-file with c2-c4
