The Kings Indian Defence is one of Blacks most dynamic 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 fourth volume of the epic Kotronias on the Kings Indian series, Grandmaster Vassilios Kotronias tackles a variety of Whites attempts to challenge his favourite opening, starting with the sequence 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6. The all-time greats Petrosian and Gligoric lend their names to systems examined after the further 5.Nf3 00 6.Be2 e5, with 7.d5 and 7.Be3 respectively, while the dreaded Exchange Variation 7.dxe5 is also discussed and dismantled. Dynamic coverage of Makogonovs 5.Nf3/6.h3, Karpovs 5.h3/6.Be3, Larsens 5.Nf3/6.Be3 and Averbakhs 5.Be2 completes this extensive work. Throughout the work, the author shares his considerable knowledge of typical positional motifs, while providing plenty of ammunition should the game erupt into the full-blooded warfare that is the hallmark of the Kings Indian. A special selection of test positions is provided, enabling the reader to sharpen his tactical skills and improve his middlegame understanding.
