The Bayonet variation (9.b4) is still one of White’s most challenging options against the King’s Indian Defence. In the game Chigaev vs Tsydypov, White opted for the relatively new plan of bringing up the a-pawn (11.a4 & 12.a5), replacing the former main move 11.Ng5.
Model games from elite players like Anish Giri, Ding Liren and David Navara will also be discussed to illustrate the potential problems Black faces in this line.
Exercise: The rollercoaster game Navara vs Shevchenko, played in August last year, also featured the move 11.a4. Can you find White’s best move?
