Kings Indian


 Perez 2273 - Schill 2250


1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.f3 a6 6.Be3 c6
this system was created by Robert Byrne, a key concept is delayed castling! White must be kept in doubt as to just where the Black King will reside.
 7.Qd2 b5 8.Bh6?! too soon 8...Bxh6 9.Qxh6 e5 10.0-0-0 Qe7 11.dxe5? this move opens the d-file for white, but much more importantly gives black squares for his minor pieces,  a bishop to e6 and a knight to c5  dxe5 12.Kb1 Be6 13.g4? Nbd7 14.Nh3 Bxc4 15.Bxc4 bxc4 16.Rd2 time to make use of our options, is it Rb8 and Nc5 maybe? 0-0-0! 17.Rhd1 Nc5 This is such a wonderful knight it ends up capturing pawns on g5,e4 AND a2 after visiting h3! 18.Qe3 Rxd2 19.Rxd2 Rd8 20.Rxd8+ Kxd8 21.Nf2 Qd6 22.Kc2 Qd4 23.Ncd1 Ne8 24.Qc3 Nc7 25.Ne3 Nb5 26.Qd2 Kc7  [26...Kc8] 27.Nf1 Kb6 28.Nd1 Nd3  [28...f6; 28...a5 29.g5 a4] 29.Nc3 Nb4+  [29...Qg1!] 30.Kd1 Nd3 31.Kc2 Nc5 32.Kd1 Qg1 33.Qe2 Nxc3+  [33...Qh1! A hard move to find with minutes left to get to move forty.] 34.bxc3 Nd3 35.Qe3+ Qxe3 36.Nxe3 Kc5 37.g5  [37.h4 f6] 37...Nf2+ blocking h2-h4 keeps the win 38.Ke2 Nh3 39.Ng4 Kd6 40.Ne3 Nxg5 41.Nxc4+ Ke6 42.Na5 Kd7 43.Nc4 f6 44.Nd2 Ne6 45.Kd3 h5 46.Kc4 g5 47.Kb4 Kc7 48.Ka5 Nc5 49.Kb4 
should the knight head into d3? invasion?
Nb7 simple! 50.Nf1 a5+ 51.Kc4 Nd6+ 52.Kd3  [52.Kc5 g4] 52...Kd7 53.Ng3 h4 54.Nf1 Ke6 55.Nd2 f5 56.Nb3 fxe4+ 57.fxe4 now black has a choice, attack? consolidate?
Nb7 58.Ke3 g4  this is clearly better for black  59.Nd2 Nc5 60.Nc4 a4 61.Nb2? white has made the final error! winning directly is....
 a3 !
two black pawns will be frozen and captured 62.Nc4 Na4 63.Nxa3 Nxc3 64.Nc4 Nxa2 65.Kf2 Nc3 66.Nd2 Kf6 67.Kg2 Kg5 68.h3 Kf4 69.hxg4 Nxe4 70.Nc4 Ng5 71.Na5 c5 72.Nb3 c4 black rests 0-1
