All of the games in KIDzine 1.4 feature the Classical King's Indian with: 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Nf3 0-0 6.Be2 e5 7 Be3 ECO codes E92 and E94 generally deal with 7 Be3 for White and 7 O-O for White (other 7th move alternatives for White are 7 d5 - the Petrosian System, and 7 dxe5 dxe5 8 Qxd8, the Exchange Variation [in the King's Indian, White usually cannot win the e-pawn with Nf3xe5 because Black has counterplay either along the e-file or the ong diagonal]), where Black responds to 7 O-O with a move other than the main line 7 ... Nc6. 7.Be3 is a very popular move because it avoids the long main lines with 7 O-O Nc6 8 d5 Ne7, with attacks on opposite wings. 7 ... Nc6 is not a particularly good reply to 7 Be3 because of 8 d5 Ne7 9 Nd2!, and if then Black moves his king's knight to enable the move ... f7-f5, for example with 9 ... Ne8, then White will be very snug after 10 Qc2 f5 11 f3 followed by castling queenside, with White initiating the play on both wings. We should also note that on 7 O-O, if Black does play the main line 7 ... Nc6, 8 d5 is usually played; 8 Be3 is not as popular here as Black can choose between (A) 8 ... Re8, and then 9 d5 Nd4! is equal, so White has to opt for the dry 9 dxe5 dxe5; or (B) 8 ... Ng4 9 Bg5 f6 10 Bc1 (10 Bh4 invites an early pawn storm against White's king) and now a good line for Black is 10 ... f5! and if 11 Bg5 Bf6 12 Bxf6 Nxf6 13 dxe5 dxe5 14 Qxd8 Rxd8 15 Nd5 Nxe4! (first played by Kasparov against Portisch) 16 Nxc7 Rb8 and it turns out that Black's center is strong. 7 Be3 A) 7 ... exd4 This move was given new meaning by Kasparov in his 1990 World Championship match against Karpov. After 8 Nxd4 (not 8 Bxd4 Nc6) Re8 9 f3 c6 10 Qd2 d5 11 exd5 cxd5 12 c5 Nc6 13 O-O, Kasparov's Exchange sacrifice 13 ... Rxe3!! 14 Qxe3 Qf8! is dangerous for White. The point of 14 ... Qf8 is to threaten ... Nf6-g4, which is not playable immediately because White can play 15 Nxc6 attacking Black's queen. Thus, in Giorgadze - Nalbandian, Capelle la Grande 1995, White played 10 Bf2 instead of 10 Qd2; this eliminates the potential Exchange sacrifice. After 10 ... d5 11 exd5 cxd5 12 O-O Nc6 13 c5 Nh5 14 Qd2, White has queenside play and a strong square on d4, but Black has some oblique pressure on the kingside. B) 7 ... c6 This was chosen in Topalov - Kramnik, Las Palmas 1996. Play continued 8.d5! (A good idea, dispensing with the complications resulting from the opening of the center in the lines below.) Ng4 9.Bg5 f6 10.Bh4 c5 (An interesting move closing the center; Black could also have played the immediate ... Ng4-h6-f7.) 0-0 Nh6 12.Ne1 Nd7 13.Rb1 b6 14.a3, and now Seirawan suggests Black should play 14 ... a6 followed by ... Ra8-a7, with a potential rooklift to the kingside. Instead, Kramnik tried 14 ... g5?! 15.Bg3 f5 16.exf5 Nxf5 17.Ne4, and White's grip on the light squares gave him the better game. After 7 ... c6, 8 O-O exd4 (Also frequently played here is 8 ... Na6; 8 ... Ng4 does not make such a favorable impression when Black has no chance to pressurize the d4 square - Budt - Martin, 1991 continued 9 Bg5 f6 10 Bd2! f5 11 dxe5 Nxe5 12 exf5 with a pleasant position for White.) 9.Bxd4! (This is a good idea now that Black cannot harass the bishop with ... Nb8-c6. White achieved little in Matamoros - Ubilava, Linares Open 1994 with 9 Nxd4 Re8 10 f3?! [better is 10 Qc2 Qe7 11 Bf3 as in Polugaevsky - Ivanchuk, Roquebriore, 1992] d5 11 cxd5 Nxd5!, which is possible because in this order of moves, the bishop on e3 is undefended) Re8 10.Qc2 Qe7 11.Rfe1 Nbd7 12.h3 a6 (The queenside expansion does not have any clear objectives here. Correct was 12 ... Ne5, posting up the knight as White's f-pawn is immobile. Also possible was 12 ... a5, clearing a spot for the knight on c5. Interesting is the pawn grab 12 ... c5 13 Be3 [White does not get the advantage on 13 ... Bxf6 Nxf6] Nxe4, when both 14 Nd5 Qd8 15 Bd3 Ndf6, and 14 Nxe4 Qxe4 15 Bd3 Qc6 are unclear.) 13.Rad1 b5 14.b4 c5 (A miscalculation losing a pawn.) 15.bxc5 dxc5 16.Bxf6 Nxf6 17.cxb5 Nxe4? 18.Nxe4 1 - 0 (Because 18 ... Qxe4 runs into 19 Bd3) Shulman - Relange, Anibal Linares Open, 1997. After 7 ... c6, 8.Qd2 is a strange move. Although White will suffer temporary embarrassment dealing with the threats to the e4 pawn and the lack of available squares for his dark-squared bishop, the idea is to put quick pressure against the weakened d6 pawn. Giorgadze - Avrukh, Anibal Linares Open, 1997, saw 8 ... Qe7 9.Bg5 exd4 10.Nxd4 Re8 11.f3 Na6 12.Rd1 Nc5 13.b4 Ne6 14.Nxe6 Bxe6 with equality, as 15 Qxd6 (White settled for 15 O-O Rad8 16 a3) Qxd6 16 Rxd6 Ng4 gives Black enough play for the pawn. C) 7...h6 (An idea popularized by John Nunn. Black intends to play ... Nf6-g4 without allowing the annoying retort Be3-g5. The main point is that White cannot similarly play 8 h3, because then 8 ... exd4 9 Nxd4 Re8 is very strong for Black, as f2-f3 weakens the g3 square.) 8.0-0 Ng4 9.Bc1 Nd7 (This was tried in San Segundo - Mollov, Anibal Linares Open, 1997. The usual line is 9 ... Nc6 10 d5 Ne7 and then, by comparison to the main lines of the Classical (with 7 O-O Nc6 8 d5 Ne7, Black has two extra moves - his h-pawn is on h6 and his knight is on g4! On 11 Ne1, Black should play 11 ... f5, rather than give the tempos back with 11 ... Nf6). After 10.d5 Ngf6 11.Be3 Nh7 12.Qc1 h5 13.b4 f5 the position was balanced. D) 7...Ng4 (This natural reaction must be considered the main line.) 8.Bg5 f6 9.Bh4 (Because White has not castled, it is convenient to post the bishop here, as White can follow up with Nf3-d2 and envision a kingside advance of his own. 9 Bd2 is, however, a viable alternative.) Nc6 10.d5 Ne7 11.Nd2 Nh6 (I think 11 ... h5 is preferable; after the text it is a little difficult for Black to organize a kingside advance.) 12.f3 c6 (This was played in Giorgadze - Shaked, Anibal Linares Open 1997; Shaked decides to push through in the center.) 13.dxc6 bxc6 14.b4 Be6 15.Nb3 d5 16.Nc5 Bf7 17.0-0 d4 (A double-edged position has arisen. White has good outposts for his knights, but Black has captured central space.) E) 7 ... Na6 (This is also often played against 7 O-O. Another new idea against 7 O-O is 7 ... Qe8, trying to exert latent pressure against e4, but a good response to that is 8 dxe5 dxe5 9 b4!) 8 O-O Ng4 (This seems better to me than 8 ... c6 9 d5! which leaves the a6 knight without a good future. Schlecht - Peng Xiaomin, Groningen 1996 continued 9 ... Ng4 10.Bg5 f6 11.Bd2 f5 12.Ne1 Nf6 13.exf5 gxf5 14.Bg5 Kh8 15.Kh1 cxd5 16.Nxd5 with a nice game for White.) 9.Bg5 Qe8 10.dxe5 dxe5 11.Nd2 was Mikhalevski - Comas Fabrego, Anibal Linares Open, 1997. Black obtained relative equality after 11 ... f6 12.Bh4 h5 13.a3 Be6 14.h3 Nh6 15.b4 Rd8 16.c5 Nb8 17.f3 Nc6 18.Nd5 Qf7 19.Bc4 Nd4.
