60m English Anti-Bayonet

King’s Indian fans who choose the Mar del Plata attack (7...Nc6) against White’s classical system (1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 0-0 6.Be2 e5 7.0-0) usually aim for a complex position with mutual attacks on open wings, requiring long-term strategic planning and tactical sharpness in critical moments. Computers often do not know how to handle the arising complex strategic positions, which suits players who like to think on their own instead of memorizing long variations. However, the fashionable Bayonet Attack (9.b4) interferes with Black’s ideas. After Black’s main move 9...Nh5 the positions opens, the lines get forced and computer analysis is important again. But this DVD offers an antidote against White’s Bayonet Attack, namely 9...a5! This move leads to sound positions with very few concrete lines, in which the focus is on strategy not on tactics. Objectively chances are equal but if Black knows what to do things might quickly become dangerous for White.
