Has the King's Indian Defense been refuted at the Grandmaster level? I know about b4 in the bayonet and the Kramnik-Kasparov games of course.  I also know that Mr. Radjabov has been unhealthy (hope he gets better soon) lately.  Thanks in advance, your site is awesome, your work on the albin counter is a gift from heaven.
Short answer - no. 

Plenty of strong grandmasters like Radjabov and Caruana still play it.
