Black is forced to pay the penalty of his previous move. Such a move on Black's part condemns by itself any form of opening that makes it necessary. White threatened Kt - Kt 5 and Black could not stop it with 4...B - K 2, because of 5 P × P, Kt × P (if 5...P × P, 6 Q - Q 5); 6 Kt × Kt, P × Kt; 7 Q - R 5, and White wins a Pawn and has besides a perfectly safe position.
