1.c4 Nf6 2.Nc3 g6 3.g3 Bg7 4.Bg2 d6 5.Nf3 0-0 6.0-0 a6 7.d4 Nc6 The Panno variation of the King's Indian defense. 8.d5 Na5 Diagram
9.b3 [My pet variation in the 1970's. It is an unusual way to combat the Panno line, but it is still quite successful for white. The main line, of course, is 9.Nd2 c5] 9...Rb8 Preparing to advance the b-pawn at some point, but the simple [9...c5 10.dxc6 gives black two options: 10...bxc6 and (10...Nxc6 with the possibility to place the rook on c8.) ; Of course, black can try the sharp 9...b5 immediately.; Black can't take advantage from the "loose" diagonal a1-h8 with 9...Nxd5? because after 10.Nxd5 Bxa1 11.Bd2 c6 12.Bxa5 Qxa5 13.Nxe7+ Kg7 14.Qxa1+ white should win.] 10.Bb2 c5 Diagram
[The thrust 10...b5 debuted on the international scene in the game Kavalek-Adorjan, Amsterdam 1977. It continued: 11.cxb5 axb5 12.Qd2 b4 13.Nd1 c5 14.dxc6 Nxc6 15.Ne1 Bb7 16.Ne3 e6 17.Nd3 Ba8 18.Nc4 d5 19.Nce5 Ne4 20.Bxe4 dxe4 21.Nxc6 Bxc6 22.Bxg7 Kxg7 23.Rac1 exd3 24.Rxc6 dxe2 25.Qxe2 and a draw was agreed.] 11.dxc6 bxc6 [After 11...Nxc6 12.Nd5!?] 12.Qd2 Diagram
This position appeared in two games I played in 1973. 12...Bf5 Something new. [12...Bg4 13.h3 Bxf3 14.Bxf3 Nd7 15.Bg2 Ne5 16.Rab1+/= Kavalek-Calvo, Lanzarote 1973. White won in 66 moves.; 12...Be6 13.Nd1! (13.Rab1? Bxc4 14.bxc4 Nxc4 15.Qc1 Rxb2 16.Rxb2 Nxb2 17.Qxb2 Nd5-/+) 13...c5 14.Ng5 Bd7 15.Ne3 h6 and now instead of 16.Nh3 white should have tried 16.Ne4 with a slight edge. Kavalek,L (2565)-Domnitz,Z (2350)/Netanya 1973. White won in 51 moves.] 13.Rac1 Re8 14.Nd4 Bd7 15.e4 c5 16.Nde2 Nc6 Diagram
[#] 17.Nd5 "You play such moves almost automatically in simos," explained Anand. "I didn't realize that Black can play 17...e5. After [17.f4 white is fine."] 17...e5 18.f4 [After 18.Nxf6+ Qxf6 the pawn on d6 is protected and the black knight lands on the square d4. Still, white can play 19.f4 Qe7 20.Nc3 with a slight pull.] 18...Nxd5 19.cxd5 Nd4 20.Nxd4 [Giving black a dangerous passer, but sacrificing the exchange 20.fxe5 Nxe2+ 21.Qxe2 Bb5 (After 21...Bxe5 22.Bxe5 Rxe5 Black's position is only more comfortable.) 22.Qf2 Bxf1 23.Rxf1 Bxe5 24.Qxf7+ Kh8 25.Bxe5+ Rxe5 gives black a clear advantage.] 20...exd4 21.Kh1 Qb6 Diagram
[#]Black is better, but Anand's next move throws the game away. 22.Rce1? c4 There is no defense against the rolling stones. 23.Bc1 c3 24.Qc2 Bb5 25.Rf3 f5 26.e5 dxe5 27.fxe5 Bxe5 0-1
