Overview
The King's Indian is a hypermodern opening, where Black deliberately allows White control of the centre with his pawns, with the view to subsequently challenging it with the moves ...e5 or ...c5. Until the mid-1930s, it was generally regarded as highly suspect, but the analysis and play of three strong Ukrainian players in particular—Alexander Konstantinopolsky, Isaac Boleslavsky, and David Bronstein—helped to make the defence much more respected and popular. It is a dynamic opening, exceptionally complex, and a favourite of former world champions Garry Kasparov, Bobby Fischer, and Mikhail Tal, with prominent grandmasters Viktor Korchnoi, Miguel Najdorf, Efim Geller, John Nunn, Svetozar Gligorić, Wolfgang Uhlmann, Ilya Smirin, and Teimour Radjabov having also contributed much to the theory and practice of this opening.
