You play the KID of course!} 3. Nc3 Bg7 4. e4 d6 5. Nf3 O-O 6. Be2 e5 (6... Na6 7. O-O e5 {In an earlier round I went for this.} 8. Re1 c6 9. Bf1 exd4 10.

Ng5 Nf6 {is the undisputed mainline.}) 11. b5 {A bit surprising and he played it quickly.} Nf6 $5 {I felt b6 wasn't such a big deal. In a way actually provoking b6.} (11... b6 $5 {is also possible, completely locking the queenside and then prepare f5. I am not sure what White intends to do.}) 12. b6 cxb6 13. Ba3 Bh6 {This just felt natural, but the bishop was also useful on g7 itself.} 14. Rb1 Bh3 15.

Nxe5 {Here if Black had the bishop on g7, Nd5 or Ne4 would have been possible.}) 17. Rxb7 {White has broken through on the queenside, but compared to the normal Kings Indian the white pieces are somewhat misplaced: Ba3, Nf3 restricted by Bh6 and Nc3 stuck to the defence of e4.} Ra7 $1 { Removing the only active piece on white's camp.} 18.

Here I had to make a major decision: f5 or Kf6. Both seemed good and the ideas were similar.} ( 41... Kf6 {Finally I rejected this in view of} 42. Rc8 $1 Rxc8 43. Bxc8 Nc3 ( 43... d3) 44.
