And by dead I mean the old Korchnoi favorite: 1. Nf3 Nf6 2. c4 g6 3. Nc3 Bg7 4. e4 d6 5. d4 0-0 6. Be2 e5 7. 0-0 Nc6 8. d5 Ne7 9. Ne1 Nd7 10. Be3 f5 11. f3 f4 12. Bf2 g5 13. a4

It's possibly the most brash attempt at refuting the KID outright that exists outside of the 4 Pawns Attack.

Black has numerous tries that have been attempted here, but if I remember correctly 13...a5 was given the best stamp of approval by the best GMs to face it, so...

13...a5 14. Nd3 b6 15. b4 axb4 16. Nxb4 Nf6 17. Nd3 h5 18. Nb5

A game that got absolutely no press, but in my opinion seems fairly important in that white's idea looked good, continued:

18...Ng6 19. Qe1!? g4 20. a5 (Guisenov-Golubev, Aeroflot Open-B 2006)

Black has other options including 18...g4, and 18...Bd7, but the Qe1 idea may be possible against both - an idea that had always been neglected in favor of the slower, and definitely ineffective Be1. The white Q is more effective on a5 than the bishop would ever be. It also slows down an ...h4 thrust by black as can be seen in the game.

I quit playing this a long time ago due to 13...a5, but this definitely caught my eye.
