The King’s Indian Defence is rather a rare bird in top class tournaments these days. Yet from the 1950s to 1990s it was high fashion, largely thanks to the efforts of Bobby Fischer and Garry Kasparov.
What happened? First of all it seems that modern players generally prefer classical openings such as the Slav Defence and there have been some effective lines developed against the King’s Indian. Perhaps the turning point came when Garry Kasparov started losing to Vladimir Kramnik with this opening.
Judging from the following game it looks like Kramnik hasn’t lost his touch, winning a model game against Alexander Grischuk at the Tal Memorial.
