Nc3 Bg7 4. e4 {When I first started to play, I choose the g3 lines against the King's Indian. Back then it seemed to me that the mainline "Mar del Plata" lines, even if objectively favourable for White, were too easy for Black to play. Strategically it seemed like a no-brainer: prep your pawn storm and sac a piece on the White pawn chain. Tactically it also seemed too easy: Black has so little space that there are really very few choices about where to put the pieces, and so even a little familiarity with it goes a long way for Black. I still think that's more-or-less right (perhaps less right for those facing professional-quality opening preparation), but last year I decided to change my White repertoire, and that meant no g3 here.} d6 5. Be2 O-O 6. Nf3 Nbd7 7. O-O e5 8. Be3 Ng4 9. Bg5 f6 10. Bh4 c6 {Diagram [#]} 11. h3 {White has fundamentally different ways to continue: exchange on e5 and play for the d-file (especially the square d6), or d5 followed by Queenside expansion. I spent some time trying to figure out which was best, only to discover at home that they're equally playable. I decided to try d4-d5, and played h3 because with a closed center Black might want to play ...h5 to support the Kingside pawnstorm, and immediatley forcing ...Nh6 stops that.} ( 11.

Bf2 Qd8 {Diagram [#] I think White has a much better version than the regular KID: White has made all the usual prep moves on both sides of the board, and Black is nowhere near to a Kingside attack: the Nh6 prevents ...h5 helping the pawn storm, the Bf6 gets in the way of the Ns. If that's right, then it's no longer the usual KID opposite side race, and White should probably go for a slower Queenside build up -- including the a-pawn or doubling on the b-file -- so that when the break comes, it's a knockout.} 18. b4 b6 19.
