The Kings Indian Defense(KID) is considered positionally busted!
It trades Positional Solidness for Dynamical Attacking opportunities.
In fact, The Legend (Himself) Garry Kasparov was a deep advocate of the KID.
Legend has it Garry Kasparov stopped playing the KID due to Anatoly Karpov.
The World Champion Karpov was a Positional Master. Karpov made a living squeezing opponents to death like a Python. Every piece would still be on the board and yet the opponent was hopelessly lost. The rumor is Gary changed his line from KID to the Gruenfeld to have better chance of winning against Karpov.
If I remember my facts correctly, Kasparov switched from the Tarrasch to the Grunfeld during his world championship matches vs Karpov. Beginning with the 1986 world championship matches, he played both the Kings Indian and the Grunfeld against Karpov in the same match.
If anyone could take credit for getting Kasparov to give up the Kings Indian, It would be Vladimir Kramnik.
