The King s Indian Defense is one of Black s most dynamic and aggressive responses to 1.d4. A favourite weapon of both Fischer and Kasparov, it remains a popular choice at all levels of play. In this, the third volume of the Kotronias on the King s Indian series, grandmaster Vassilios Kotronias presents the second part of his world-class repertoire against the famous Mar del Plata variation, starting from the position after 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 0 0 6.Be2 e5 7.0 0 Nc6 8.d5 Ne7, with the focus on 9.b4, 9.Nd2 and all other sensible alternatives to 9.Ne1. Once again, Kotronias provides a turbo-charged repertoire for Black, with a plethora of novelties and original analysis. As well as providing detailed analysis, the author also shares his considerable knowledge of typical middlegame themes, both positional and tactical. A special selection of test positions is provided, enabling the reader to sharpen his tactical skills and increase his middlegame understanding.'
