Oleksandr Sulypa: Destroying the black's pawn structure in the King's Indian defense The pawn structure in the king's Indian defense is considered one of the most reliable. White usually try to advance his pawns on с5,  put knights on c4 and and b5 and attack the pawn d6. Black’s main strategy is based around to  playing f5-f4,g5-g4,h5 f5-f4,g5-g4,h5 and try to open white’s  position. He doesn't care if it costs him a  pawn as in return he will get open lines and outposts for his pieces. If white will lose time or play very slowly, they will come under attack. Let's see an example of a radical method of play for white - destroying the pawn chain on the victim material. Kramnik V. : Nakamura H. Khanty-Mansiysk 2010 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.Nd2 Ne8 10.b4 f5 11.c5 Nf6 12.a4 f4 13.Nc4 g5 14.Ba3 g4?! 14...Ng6. 15.cd6 cd6 16.b5!

But White misses another tactical trick! 35.Rac1 Qa4 36.Rc8 Kg7 37.Rec1, and even now, although white has only two rooks against black queen and knight - white pawns are potentially stronger material. 35...Nc2! 36.Rac1 36.Ra2 Qe8! and White can't protect the pawn e4. 36...Qa4 37.d6 Again unable to protect the e4 –   pawn, White forces a draw. 37.Kf3 Nd4 38.Ke3?!

After the base of the pawn chain - the pawn d6 is destroyed starts the destruction of the strong knight d4. 25.ef5?! gf5 26.Rb7 Qg5 Black receives some counterplay via g-line. 25...Nb5 25...Rb8 26.Rb8 Qb8 27.d7 Qc7 28.ef5 gf5 29.Bd4. 26.Qb3 Qe8 27.Red1 Rd8 28.Nb5 ab5?!

Better was 28...cb5±. 28...cb5±. 29.a4 ba4 30.Qa4 White easily penetrates his pieces into black camp with decisive attack on the 7 – th th line. 30...Bf8 30...Qd7 31.Rb6 Rc8 32.Qb3+ – . 31.d7! Qf7 31...Rd7 32.Rd7 Bc5 33.Rbb7. 32.Qa5 1:0.  Ragger M. : Grischuk A. Skopje 2015

This game is notable for the fact that White three time donated the material to destroy the  base of the pawn chain d6, and only only on the third time they succeeded. 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.Nd3 f5 11.f3 f4 So, the starting position is set. Black closes the centre in anticipation of an attack against the white king. This is the real starting point of the variation and in a tournament game this  position would often be reached after just a couple of minutes play. 12.Bd2 Nf6 Other line is 12...g5 13.Rc1 Ng6 14.c5.

The first opportunity to sacrifice material! 17...cd6 It is dangerous to pick up the bishop, because the white pawns will be the winner in the

subsequent play. 17...ba5 18.dc7 Qf8 19.Nc5 (19.Qa4 g4 20.Nc5 gf3 21.Bf3±) 19...a6 20.Ne6 Qe7 21.Ng7 Kg7 22.d6 Qe8 23.Na3 Be6 24.Nc4 Qb5 25.Qb3 Qc5 26.Kh1 Nd7 27.Qa4 Rff8 28.Qa5 Qd4 29.Qc3 Qa7 30.b4 h5 31.a4 g4 32.Na5 Nh4 33.Qe1 Ng6 34.Qf2+ –  Qe3  Qe3 35.Bc4 Bc4 36.Nc4 Qb3 37.a5 Qb4 38.Nb6 Nb6 39.ab6 Qd6 40.b7 Rac8 41.bc8Q Rc8 42.Qc2 Nf8 43.Rfd1 Qe7 44.Qc5 Kf6 45.Rd6 Ne6 46.Qd5 gf3 47.gf3, 1:0, Mchedlishvili M. : Rustamov A., Tashkent 2010. 18.Be1 a6 Better was immediat attack 18...g4!? 19.Nb4 a6 20.Nc6 Qf8 21.Qa4 (21.Nc3 h5‚ (or 21...g3!?) ) 21...Ne4! 22.fe4 f3 23.Bd1 Bd7©, Bd7©, with good compensation for the knight. 19.Nc3 a5 Don't really want black to allow the white knight on c6.On the other hand field b5 appears for another white's knight. Now the attack is not so successful: 19...h5 20.Nb4 Bh6 21.Na4 Rb7 22.Bf2 Nd7 23.Ba6 Ra6 24.Na6 Nc5 25.N6c5 bc5 26.b4 Rb4 27.Rb1+ – , Yuferov S. : Dydyshko V., Minsk 1978. 1:0 (38). 20.Bf2 Rb8 21.a4  Not so clear 21.Nb5 Bf8 22.Rc6 22.Rc6 Ne8 23.a4 3

 

Bd7 24.Rc3 Nf6 25.b4 g4 and I think Black have good attacking chances. 21...Bf8 22.Nb5 g4 Looks preferable 22...Ne8 23.Rc6 Bd7 24.Rc3 Rb7 25.b4 h5 26.ba5 ba5 27.Na7 Nf6 28.Nc6 Qa8 29.Qc2 g4. 23.Rc6 Rg7 All maneuvers of the black pieces are  prepared breakthrough on the kingside kingside and, of course, the defence is not necessary to forget. While hold the line is not so important. 24.Qc2 Bd7  Now 24...Ne8 is impossible , cause of pawn pawn g4.
