Hello friends!
Position 4.2 from The process of decision making in chess Volume 2, goals and plans.
It's white's turn.
Diagram 4.2- white has the g6 and e5 critical squares, while black has h2 and g2.
White can create great attacking chances by increasing the number of his critical squares in black’s camp by playing Bb3, making f7 a new critical square and thus creating a double threat, after which black’s position is lost; he can’t defend against Qxg6 and defend the f7 pawn at the same time.
Challenge: is there an immediate refutation of Bb3 …Rf6? Or is it only a positional advantage for white after Rxf6 in the form of black’s weak kingside pawn structure?
