Contents Colle-Zukerto rt Opening The variation with d5 and c5 •Z The variation with d5, but not c5 J The variation without d5 Opening repertoire for White with l.d4 In this lesson we will lay the foundations for an opening repertoire for White based on l.d4. Of course we cannot discuss all openings at once. I shall present some systems which I myself use. White has two main ways of developing his king’s bishop, either a fianchetto after g2-g3, or along the fl-аб diagonal (normally on e2 or d3). The first strategy leads to the following openings: Catalan Opening, Queen’s Indian Defence with g3, King’s Indian Defence, Griinfeld Defence or Benoni Systems with g3. The second strategy leads to the Queen’s Gambit, the Slav Defence, the Nimzo- Indian Defence, the Queen’s Indian Defence with e3 or various systems in the King’s Indian Defence, Griinfeld Defence and Benoni. However, White can avoid a lot of theory if he limits himself to the Colle-Zukertort Opening (l.d4, 2.£f3 and З.еЗ). This is a particularly good choice against those who play the Nimzo-Indian or Queen’s Indian. Here is an example ofWhite’s strategy. L.Psakhis USSR Ch, Moscow 1983 l.d4 2.£if3 еб З.еЗ c5 An alternative is the immediate 3...d5. 4.1d3 d5 Another plan is 4,..b6. White can then transpose to the Queen’s Indian by 5.0-0 Jib7 6.c4. This move order allows White to avoid the best plan for Black: 1 .d4 £jf6 2.c4 еб 3.£)f3 b6 4.e3 Jlb7 5.jtd3 and now either 5...Js.b4t or 5...d5 followed by ...<<bbd7 and .. JLd6. 5.b3 This prevents ...c5-c4. 5..^e7 6.0-0 0-0 7.1B2 b6 Black is not exerting any pressure and White gets what he wants. 8.£)e5! Diagram 5-1 56
Opening repertoire for White with l.d4 White’s strategy is simple: occupy the e5-square and control the other central square e41 8...1b7 9.&d2 £)c6 10.f4 An important move. White strengthens his control over the e5-square. If Black now exchanges the knight, White usually recaptures with the f-pawn, in order to open the f-file. 10...cxd4?! This exchange is almost always good for White, since he gets the e-file and can defend the e4-square even better. Il.exd4 &b4 If ll...§c8, then you must guard against 12...£)b4; the best way is with 12.a3. 12. Де 2 Ec8 13.c3 2)c6 14.^d3 Black has achieved nothing. 14...£d6 15.W13 15.We2 would also be good. White could then bring a rook via f3 to h3, to prepare the attack. 15...^e7 16.Sael g6 All Black can do is defend. 17.®h3 Diagram 5-2 But this is not energetic enough! The immediate 17.g4! would be better. 17...h5! 18.Ы13 19.^g5 Despite the inaccuracy, White is clearly better here. 19...Дхе5 2O.fxe5 ^g4 21.Jfxf5 exf5 22.Дс1! Black has problems: his dark squares are too weak. But Psakhis defends his position very cleverly. 22...®e7 23.®g3 Даб 24.h3 It is even better to play 24.§f3 and then h3. 24...ДхП 25.hxg4 fxg4 26.Scfl 16 27.exf6 Sxf6± Although Black later saved the draw, the position was very much to White’s advantage. Diagram 5-2 abcdef gh Black has three main continuations against White’s set-up: he plays d5 and c5, he plays d5 without c5, or he plays without d5.

Opening 1 l.d4 2.&B еб З.еЗ c5 4.1d3 d5 4...b6 is the alternative. 5 .b3 ^c6 This is the most active position for the knight. 6 .ЯЬ2 Де7 6... Jld6 is an interesting alternative. After 7.0—0 0-0 a transposition to the Queen’s Indian is possible: 8.c4 b6 9.^c3 tb7 10.Be2±. If instead Black plays 7...Wc7 (intending either ...e5 or ...cxd4 followed by ...£)b4) or 7...We7, then White may also reply 8.c4!?. 7.0-0 0-0 8.&bd2 Diagram 5-3 White develops his pieces very harmoniously. The bishops are working along adjacent diagonals and putting pressure on the opposing castled position. 8...b6 9.?Ie5 £)b4 This does not achieve much for Black. There are decent alternatives in 9...ДЬ7!?± or 9...£ixe5 10.dxe5±. 1О.Де2ЯЬ7 Il.f4£)e4!? This is the only weakness in the white position. 12.£lxe4! White immediately swaps off the strong knight and ‘plugs’ the e4-weakness. 12...dxe4 13.a3 £ld5 13...£lc6± deserved consideration. 14.Bd2 Ec8?! Black makes an error: he is not worried about the strong e5 knight. The immediate 14...f6± would be better. 15.c4 16.Sadl± JLd6 17.dxc5!? White opens the diagonal for the bishop. 17...Дхс5 18.Wc3 We7 19.6’? Diagram 5-4 White also wants to open the f-file. 19.^d7 Jlxe3t 20.®xe3 £)xd7 would not be so clear-cut.

Otherwise White would be able to control the e4- square with Wf3. 9.c4l? After 9.Bf3?l comes 9...f51. But 9.^xe4 dxe4 10.JLe2 is an alternative. 9...&d7 Ihis move is not a mistake.

The correct move was 28...We7!=. 29.Sa5!± With a blockade on the dark squares and the plan of <Йа2, Bc5, £)b4. White went on to win the game.

Here ll.Wa4 Sd7 12.£)e5? is bad, due to 12...^xc3.', so White would do better to play 1 l.jLc4!?. 60
Opening repertoire for White with 1 .d4 10...0-0 1 l.Wg4 ll.Wh5 is perhaps more accurate, because now Black could exchange on c3. 12.Ж4 2>bd7?! 12...£e4!? 13.Bh3 ®xd4 14.£xf7!? 2xf7 15.^xe4 Дхе4 16.Bg4± offers White a pleasant endgame.

Diagram 5-9 15 .d5I! £>xc3 15... exd5?? loses on the spot to 16.JLxe4. 16 .bxc3 JLxd5 16... exd5 loses the exchange: 17.^d7! h6 (17...@xd7?? 18.1xh7t+-) 18.W8 ®xf8 19.1e3 @c8 20.®xc8f Sxc8 21.jLd4± Yusupov - Shneider, Moscow 2003. 17.1g5 h6? 17...g6 would be more stubborn, although after 18.®h4 (threatening c4) the position is better for White. Diagram 5-10 18.ДхЬб! gxh6 19.®xh6 Wc7?I Also bad are 19...®b8? 2O.^d7+- and 19...Se8? 2O.JLg6!+-. 19...®c8!? would be somewhat more resilient: 20.c4 jib7 21 .Wg5t ^h8. But here too White wins after 22.Sei! and then Se3-h3. 20.®g5t ®h8 21.Wh4t Black loses his queen after 21...^g7 22.Wg3t followed by £lxf7t. 1-0 dhe test which follows should help improve your understanding of the typical ideas behind the Colle- Zukertort. Try to consider the exercises as though they were situations from a game and to make a decision after a maximum of 10 minutes thought. The score on this test is not so important. But it is very useful to go on to study both the solutions and the sample games very thoroughly and to remember the typical ideas. Please solve them in order, since some exercises are linked to ones you have studied previously! Diagram 5-9 abcdefgh Diagram 5-10 abcdefgh 61
