The repertoires below offer you solid and aggressive ways of playing against most of the Queen's side openings, and also tells you what to do against some of the less common lines where only one line need be learned.

*Playing solidly against the
Queen's-side and flank openings*

Black's basic solid set-up |
When I say solid, I mean, solid and going forward, not solid and standing still. So, you must plan where your counterplay is coming from: play ...e5 to get your Bc8 out and working play ...Bd6 and ...Qc7 play ...Bb4 and ...Qa5 play ...dxc4 and ...b5 Of course you can combine these plans. |

play ...e5 to get your Bc8 out |
play ...Bd6 and ...Qc7 |
play ...Bb4 and ...Qa5 |
...dxc4 & ...b5: keep the P/ hit

Under the ** Section A, Queen Pawn
Openings** you can see both these lines at work. You
can see straight away that it may be possible to head towards one
then choose the other.

I'll also show you how to play against some of the more off-beat approaches to playing White in sections B-F. Analysis and Games

** **

I'll go through each approach in turn, looking at a system to play against each White opening.

As your chess improves you will meet more and more players who prefer the slower Queen's-side openings, which although slow, are dangerous because they are also trying to take over the centre, and it is harder to stop this than after 1. e4. The reason for this is worth thinking about:

In the e4 openings, you can often easily play ...d5, but in the 1. d4 openings, ...e5 takes a lot longer to arrange. You may prefer to give up on the idea for a while, and concentrate on active development.

There are several systems below which combine solidity and winning chances in varying proportions:

The Cambridge Springs Defence to the Queen's Gambit Declined

The Semi-Slav Defence: the Tchigorin, Romih and Abrahams variations

The Stonewall Dutch

* *

* *

*A1 Playing solidly against
1. d4*

I assume that White will follow 1...d5 with 2. c4. Sometimes White will play 2. Nf3 and later 3. c4, but basically White usually needs the c2-c4 move to put Black's centre under pressure, or Black will be able to use the c7 and e7 pawns to hit out at the d4 pawn. There are a few White systems that don't involve c2-c4:

*

### The Stonewall System

1. d4 2. e3 3. Bd3 and 4. f4*

### The London System

1. d4 2. Nf3 3. Bf4*

### The Colle System

: 1. d4 2. Nf3 3. e3 4. Bd3 (*see the booklet devoted to this opening*

(Notes from Fine, 1943)

**1. d4 d5 2. e3 Nf6 3. Bd3**

*[3. f4 is sometimes played to avoid the 3...Nc6 line. Black
can always play ...Bf5]*

**3... c5**

*[Another good system is 3... Nc6 4. f4*

*[4. c3 e5]*

*4... Nb4 5. Nf3 Nxd3+ 6. cxd3 g6 7. Nc3 Bg7 8. O-O
O-O=]*

**4. c3 Nc6 5. f4**

**5... e6**

blocks the Bc8; probably not best.

*[5... Bg4 6. Nf3 e6 7. Nbd2 Bd6 8. h3 Bh5 9. b3 cxd4 10.
cxd4 Rc8*

*Black is comfortable]*

The dangers in this line can be seen in this line, given by Fine:

**6. Nf3 Bd6 7. O-O O-O 8. Ne5 Qc7**

Ne5 needs some response; Black could also try to occupy e4

**9. Nd2 Re8 10. g4**

with a crushing attack

This can be a dangerous system: e.g.

**1. d4 d5 2. Nf3 Nf6 3. Bf4 c5 4. c3 e6 5. e3 Be7 6. Nbd2
O-O 7. Bd3 b6 8. Ne5**

*[8. O-O Bb7 9. a4*

*[9. Ne5]]*

**8... Bb7 9. Qf3 Nc6 10. Qh3 g6 11. Bh6 Re8 12. f4
Nd7**

*[12... Nxe5 13. fxe5 Ne4 14. Bxe4 dxe4 15. O-O with a strong
attack: White can contemplate Rxf7!]*

**13. O-O f5 14. Ndf3 Ncxe5 15. fxe5 Bf8 16. Ng5 Bxh6 17.
Qxh6 Nf8**

*[17... Qe7 18. g4 Qg7 19. Qxg7+ Kxg7 20. Bb5 Rad8 21. gxf5
gxf5 22. Nh3 with an endgame plus]*

**18. Rf3 Re7 19. g4 Rg7 20. Raf1 Qd7 21. Kh1 Qe7 22. h4
Bc8 23. Rg3 a5 24. Rfg1 Ra7**

Black fiddles while the King's side burns... White won an endgame in about 40 moves.

Let's try again from the top:

**1. d4 d5 2. Nf3 Nf6 3. Bf4 c5 4. c3 e6 5. e3 Be7 6.
Nbd2**

**Now 6... Nc6**

Black should be prepared to snap off a Knight coming to e5, and can also think about ...Nh5 to exchange the Bishop.

**7. h3**

*[or 7. Bd3 Nh5 8. Be5 f6 9. Bg3 g6 10. Qe2 O-O*

*Eslon-Cramling, 1984. BCO confidently gives this as an edge
to Black. The Black pawns look odd but cover a lot of key squares.
If White castles King's- side Black will play ...Nxg3; if O-O-O
Black should not open a file but ...a6.]*

**7... O-O 8. Bd3 b6 9. O-O Bb7 10. Ne5 Nxe5 11. Bxe5 c4
12. Bc2 b5 13. a3 Nd7**

**= Remon-Agzamov 1984**

The only other system which may cause concentr is the Colle System; early development of the Bc8 to f5 or g4 is the antidote (see booklet).

White has other non-standard plans eg...

*[3. g3 c5 4. Bg2 e6 5. O-O Nc6 6. c3 Qb6 7. e3 Bd6*

*= Ardiansyah-Farago 1983.]*

....but these should not cause you sleepless nights. The strongest move is c2-c4, so let us look at these variations.

** **

**A1.1 The Cambridge Springs
Defence against the Queen's Gambit**

The Queen's Gambit is a strong and solid approach for White.

**1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. Bg5**

The main line is 4...Be7 but the line I recommend starts:

**4... Nbd7**

Can White win a pawn here?

*[5. cxd5 exd5 6. Nxd5 Nxd5 7. Bxd8*

*[7. Bd2 N7f6]*

*7... Bb4+ 8. Qd2 Bxd2+ 9. Kxd2 Kxd8 and Black has an extra
piece!]*

No, so White usually continues:

**5. e3 c6 6. Nf3 Qa5**

This is the Cambridge Springs Defence, a counter-attacking line where Black aims to put the White Queen's-side under pressure. White has ways of heading off to other variations on moves 4,5 and 6 and we will look at those later. First, let us look at an example game:

*Marshall,F - Tarrasch,S, Nuremberg,
1895*

**1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. Bg5 Nbd7 5. e3 c6 6. Qc2
Qa5**

**7. cxd5 Nxd5 8. Nf3 ? 8... Bb4 9. Kd2**

Black's attack on c3 has given White a real headache.

**9... c5 10. a3 Bxc3+ 11. bxc3 cxd4 12. exd4 N7b6 13. Bd3
Bd7 14. Rhc1 Rc8 15. Qb3 O-O**

**16. Ke2**

*[16. Rc2 Ba4]*

**16... Rxc3 17. Rxc3 Qxc3 18. Qb1 h6 19. Bd2 Qc7 20. Kf1
Nc4 21. Bc1 Ba4 22. Qa2 Rc8 23. Qe2 Nc3 24. Qe1 Na5 25. Bxh6 Nb3
26. Bd2 Nxa1 27. Qxa1**

**27... Bb5 28. Bxb5 Nxb5 29. g3 Qc6 30. Kg2**

**30... Rd8 31. Be3 Qe4 32. Qb2 Rd5 33. a4 Nd6 34. Bf4 Nf5
35. Be3 Nxe3+ 36. fxe3 Qxe3 37. g4 f5 38. g5 Qe4 39. Qc3 f4 40.
Qc8+ Kh7 41. Qc3**

**41... e5 42. h4 Rxd4 43. g6+ Kh6 44. Kh2 Qe2+
0-1**

Quite a long haul, but not difficult to understand. I predict you will win a few games like this to White players who do not really see the attack coming. All the theory below is designed to give you enough ideas to see you through games where your opponents do know what they are doing.

From the main line position:

White has several different moves here, but the same ideas are present in each line: White hopes to safeguard the bishop on g5 and/or to minimise the attack on c3. We will look at:

a. 7. Nd2, stopping ...Ne4

b. 7. Bxf6, removing the target

c. 7. Bd3 - a poor move (...dxc4!)

d. 7. cxd5 - stopping ...dxc4

The first and last of these are the most important and most common amongst masters.

A1.1a Cambridge Springs with 7. Nd2

Black has got two ways to try and equalise here I recommend 7. Nd2 Bb4 but Black has also tried

*7.Nd2 dxc4*

*e.g.*

*8. Bxf6 Nxf6 9. Nxc4 Qc7 10. Rc1*

which may be about equal but I don't fancy it as well. Let's try instead

**7. Nd2 Bb4**

**8. Qc2 O-O**

*[8... e5 also equalises according to Polugaevsky]*

**9. Be2**

White has also tried:

*[9. a3 Ne4]*

*[9. Bh4 e5*

always this blow! But Black can also try

*[9... c5 10. Nb3 Qa4 11. Bxf6 Nxf6 12. dxc5 Qc6 13. cxd5
exd5=]*

*10. dxe5*

*[10. Nb3 Qc7 11. Be2 [or 11. Bg3 Ne4] 11... dxc4 12. Bxc4

*[13. e7 Re8 14. O-O-O Ng6 15. Rd8 Bf5]*

*16. Bxd3*

*[16. Kb1 Bxc3 17. Qxc3 Qxc3 18. bxc3 Re8 with good
compensation for the piece]*

*16... exd3 17. Qd2 c5 18. axb4 ? 18... cxb4 19. Nb1 Rc8 20.
b3 b5 with a strong attack for the piece]*

**9... e5**

**10. O-O**

Again White has tried other moves:

*[10. dxe5 Ne4 11. Ndxe4 dxe4 12. O-O Bxc3 13. bxc3
Nxe5*

*[13... f6 14. Bh4 Qxe5 =]*

*14. Qxe4 Ng6 15. Bf4 Nxf4 16. Qxf4 Qxc3*

*[11. c5 Be7 12. b4 Qc7*

*with chances for both sides; White has more space but while
Black maintains the tension in the centre it will not be easy for
either side*

**11... Qc7 =**

**9... c5**

Black has a simple equalising plan: exchange centre pawns, castle, then develop your Bc8.

**10. Nd2** *[or 10. O-O]* **10...

**= Kmoch-Vajda, Kecsemet 1927**

A1.1c Cambridge Springs with 7. Bd3

This is a feeble move, although it looks natural.

**7... Ne4 8. Nd2**

*[8. Bf4 Nxc3 9. bxc3 Qxc3+ 10. Kf1 dxc4]*

*[8. Bxe4 dxe4 9. Ne5 Bb4]*

**8... Nxd2 9. Qxd2 dxc4**

And Black has won a piece.

A1.1d Main line Cambridge with 7. cxd5

**7...Nxd5**

Now White usually plays Qd2 but first we will need to examine an alternative in 8. Qb3.

A1.1d(a) White deviates from main line: 8. Qb3

**8. Qb3 Bb4**

Others can be confidently tried:

*[8... h6 9. Bh4 Bb4 10. Rc1 c5 11. a3 Bxc3+ 12. bxc3 cxd4
13. exd4 O-O = Euwe-Capablanca 1931]*

**10. Bc4 !**

Best. Alternatives include:

A1.1d(b) Back to the main line with 8. Qd2

**8. Qd2**

Black now has the sharp

8... N7b6

and the solid

8...Bb4

**A1.1d-1 Main line with 8...
N7b6**

Now White has a choice:

(1) 9. Bd3

(2) 9. Nxd5

(3) 9. a3

(4) 9. Rc1

Only the last of these is dangerous.

d-1(1) Main line with 8...N7b6 9. Bd3

**9. Bd3 (?)**

This move anticipates transposing to the Rc1 system after

*9... Nxc3*

but Black can dodge with

**9... Na4 !**

with no problems after

**10. Nxd5**

*[or 10. Nxa4 Bb4]*

*[or 10. O-O Nxb2 11. Qxb2 Qxc3 -+]*

**10... Qxd2+ 11. Kxd2 exd5 drawn: Adorjan-Ivkov
1980**

This is worth knowing about, because it is not in all the books.

d-1(2) Main line with 8...N7b6 9. Nxd5

An attempt to avoid any theoretical novelties, but abandining any pretence at keeping the White advantage.

**9... Qxd2+ 10. Nxd2 exd5 11. Bd3 a5**

**= Karpov-Kasparov 1984/85 #47**

d-1(3) Main line with 8...N7b6 9. a3

**9... Nxc3**

the pawn grab with ...Bb4 is rather risky

**10. Qxc3**

*[10. bxc3 Nd5 11. e4*

*[11. c4 Bb4]*

*11... Qxc3]*

**10... Qxc3+ 11. bxc3 f6 12. Bh4 c5**

*[11... Ba3 12. Rb1 Nxc3 13. Rb3 b5 14. Bd3 b4 Black can win
a pawn but the Ba3 is dead for a long while]*

**12. O-O b5**

*[12... Bb4 is risky 13. a3]*

**13. d5**

This is the only threatening continuation

*[13. Qxc3 Qxc3 14. Rxc3 bxc4 15. Rb1 Ba6 16. Nd2 c5*

*with better chances for Black]*

**13... exd5 14. Bxd5 cxd5 15. Rxc3 Bb4 16. Qxd5 O-O 17.
Qxa8 Bg4**

Black's chances are no worse

** **

** **

**A1.1d-2 Main line with 8...

this more straightforward move leads to quieter play

**9. Rc1 O-O**

**10. e4**

*[10. Bd3 e5 11. dxe5*

*[11. O-O exd4 12. exd4 f6 13. Bh4 Rd8 14. a3 Bxc3 15. bxc3

* *

This is all the theory you will ever need if White allows the Cambridge Springs. Play over each line, not to learn the moves by heart but to see all the different ideas. Once you know the ideas the moves will come naturally to you - perhaps better moves than are given in the notes!

**A1.1e White avoids the Cambridge

White has tried

A. 6. Qc2

c. 6. e4

e-1(1) 6. Qc2

Now the usual attack can be easily met by

*[6... Qa5 7. cxd5 Nxd5 8. e4 Nxc3 9. Bd2]*

An active try is:

**6... dxc4**

*[6... h6 is safer 7. Bxf6 Nxf6 8. e3 Be7 9. Bd3 O-O 10. O-O

**7. e4 b5 8. e5 h6 9. Bh4 g5 10. Nxg5 hxg5 11. Bxg5

Compared to the normal Anti-Meran system (see below), White has played the inferior move Qc2 not g3. Black will get a good game with ...Qb6 and ...O-O-O. See the section on the Semi-Slav below.

The what? The Catalan is an opening which involves c2-c4 but not e2-e3. White holds back the e-pawn and instead plays the light-squared Bishop out to the long diagonal on g2. So how can White capture the c-pawn if Black takes it? Quite!

**1. d4 Nf6 2. c4 e6 3. g3 d5 4. Bg2 dxc4 5. Nf3
b5!?**

*"Boy, did I underestimate this one!"*

*SCHILLER, Play the Catalan*

This is a sneaky way of grabbing a pawn. White can play 5. Qa4+, but otherwise play is like the Abrahams' Variation game Seirawan-Korchnoi on page . Both Korchnoi and Karpov have tried this line, which is probably not totally sound but White will have to walk a tightrope to find the way to advantage.

If you don't fancy this line then uncoiling slowly with usual Slav-style moves will probably equalise. The game is too unforcing to give much detailed analysis.

I'll show you a game by Korchnoi and one by Karpov, and look at the latest theory.
