About this ebook
Moskalenko’s previous and highly popular chess opening books were mainly written for the Black pieces. Now he presents an extremely powerful set of lines for White. The guiding principle of his 1.d4 repertoire is: be bold and put pressure on your opponent as early as possible.
Moskalenko does not shower you with long computer-generated variations, but has a keen eye for the essence of positions. His talent to find new resources in well-known lines results in a host of novelties, daring recommendations and cunning tricks.
When you play his lines and follow his recommendations you will frequently surprise your opponent and build up positions full of swing. Studying An Attacking Repertoire for White with 1.d4 is a delight because this is a typical Moskalenko book: practical, accessible, original, entertaining and inspiring.

An Attacking Repertoire for White with 1.d4 - Viktor Moskalenko
1
King’s Indian Four Pawns Attack
The infantry is the soul of an army – Alexander V. Suvorov, Russian Field Marshal (1729-1800).
A bit of history
Without a doubt, the King’s Indian is one of the most popular defences. It has been used for a long time by players of all levels. By the way, in Russia it is called ‘Staroindiskaya Zaschita’, the ‘Old Indian Defence’, as opposed to the New (= Queen’s) Indian. It is an excellent option for Black, and a very powerful and practical weapon. It offers its followers strategically easy plans and almost always leads to complex play.
It is not necessary to mention all the elite players who have this defence in their repertoire. Suffice it to say that one of them was the great Garry Kasparov, who was the greatest expert and a champion of the KID for many years. As for white players who begin their game with 1.d4, they must come very well prepared for this defence and its theoretical concepts and practical ideas.
Personally, throughout my career so far, I have tried out nearly all the possible variations against the KID, but I have never liked repeating the long fashionable lines, some of which require theoretical analysis up to move 20 or 30.
In the 1990s I decided to enlarge my repertoire against this defence with something original that would correspond to my personal playing style. After some successful attempts I discovered that the Four Pawns Attack was exactly what I was looking for: underdeveloped theory and active play for White, thanks to the advanced central pawns.
1.d4 ♘f6 2.c4 g6 3.♘c3 ♗g7 4.e4 d6 5.f4
Who could ask for more?
In this first chapter, I would like to share with the reader a few secrets that have been discovered during a long period, and to present some lines that are highly unusual to the present day. With these lines I myself have harvested some very important points against players of different levels for a number of years.
The strategic ideas of the Four Pawns Attack versus the King’s Indian are quite aggressive and lead to complex middlegames. The arising positions contain numerous options for both colours. I have written Surveys on this variation in Yearbooks 82, 83, 85 and 88, and Yearbook 87 features an article on a similar approach to the Benoni (see Chapter 3).
Statistics Moskalenko
Total 72 games = 76,4%. Performance = 2654.
1-0 = 55 games; draw = 15; 0-1 = only 2!
Resources for White
• White has a very strong centre and he must use this to dominate the play. There are good possibilities of a strong attack on the kingside. Normally in the Four Pawns, the middlegame starts quite soon, and Black will counterattack in the centre and on the queenside. White must try to maintain his strong centre;
• After correct play in the opening, followed by a complex middlegame, normally White reaches a favourable ending, due to the fact that he has more space and better development, and also due to the dynamic characteristics of the pawn structure.
A different pawn wedge (Games 1-6)
After 5...0-0 6.♘f3 c5 7.d5 e6 we arrive at one of the main positions of the 4P. Now, surprisingly, White plays 8.dxe6!.
A quite paradoxical move for theoretically inclined players!
• By exchanging the d5-pawn and opening the d-file, White obtains a dynamic central pawn structure e4/f4 with good options of pushing e4-e5 or f4-f5 later on. In addition, Black’s d6-pawn is now much weaker.
• The character of the game becomes more dynamic. Both sides immediately start to fight for the initiative, and the games in this line are very exciting.
Resources for Black
Black must try to reduce White’s domination. The games of the great player Garry Kasparov may help black players to solve their doubts regarding the direction their analyses should take.
Facing the Four Pawns, Kasparov has chosen three different lines:
Developing the bishop: 8...♗xe6
In his 1976 game against Murey, Kasparov played 8...♗xe6 (Games 1, 2). Black develops the passive bishop while keeping the e-file open for his rook. White’s best reply is 9.♗d3, intending to push his pawns and start an attack. Now Black must quickly look for effective counterplay, as one of the downsides of 8...♗xe6 is that the attacking advance f4-f5 can be played with tempo.
A) Kasparov played 9...a6 instead of the more common 9...♘c6 or 9...♗g4, to prepare the ...b7-b5 advance (Game 1);
B) Various examples given in the notes to Game 2 illustrate that Black is not in time with 9...♗g4, with the idea ...♘b8-c6-d4. So for White, careful preparation of the attack with 10.0-0 is healthier in my opinion. After 10...♘c6 11.h3! ♗xf3 12.♕xf3 ♘d4 13.♕f2, the critical position arises.
White has good attacking potential.
The flexible move 8...fxe6
Six years later, Kasparov tried 8...fxe6!?. This is probably the best response, and now the natural 9.♗d3 ♘c6 10.0-0.
This is the main position of the Pawn Wedge line. Here there are a great number of possibilities. Let’s examine them.
Game 3: some early deviations, and the ‘theoretical’ move 10...♔h8?!.
KEEP IN MIND
The manoeuvre 11.♘g5!? is nearly always favourable for White! This move is very annoying for Black. White starts activity in the centre and on the kingside.
(see diagram next page)
Game 4: the main possibilities against Black’s slow plans with 10...a6, 10...e5, 10...♕e7, 10...♗d7 and 10...♘h5.
Games 5 and 6: Black’s most dynamic, and most popular, move is 10...♘d4!?, played in Christiansen-Kasparov, Moscow 1982. Now 11.♘g5 e5! is very complicated, but also interesting is the solid option 11.♘xd4 cxd4 12.♘b5!.
In both games, Kasparov achieved a good result basically because of his combativeness, since he had to go through some difficult moments.
Warcraft against the Four Pawns Attack (Game 7)
7...b5
In this aggressive line, similar to (but not exactly the same as!) the Benko/ Volga Gambit (1.d4 ♘f6 2.c4 c5 3.d5 b5), both armies must use their pawns. Black’s usual moves are: ...b7-b5/...a7-a6/...e7-e6/...d6-d5 and White’s: cxb5/bxa6/a2-a4/dxe6/e4-e5/f4-f5.
8.cxb5 Accepting the pawn is the most principled move, although the dynamic 8.e5 is also possible.
After 8...a6, the main continuation 9.a4! is the richest in possibilities for both sides. The aim is to place an obstacle on b5 in such a way as to reduce Black’s activity on the queenside. Now it is not easy to find a good continuation for Black. We shall examine the three main possibilities: 9...♕a5, 9...axb5 and the ‘Benoni line’ 9...e6.
KEEP IN MIND
Evidently, Black’s fast counterattacks on the queenside are delayed and his activity there is already sufficiently limited now.
Waterloo (Games 8 and 9)
Never interrupt your enemy while he is making a mistake – Napoleon Bonaparte.
6...♘a6!? was chosen even by Garry Kasparov in his last game against the Four Pawns Attack. Please note that this was the third time that Kasparov changed variations against the Four Pawns.
This seems a very strange manoeuvre, but it is in fact the start of a solid and effective plan. Black’s initial objective consists in the preparation of the blocking advance ...e7-e5. This is combined with the jump of the knight from a6 to c5, attacking pawn e4. Since the light-squared bishop’s diagonal is open, it can ‘shoot’ to g4.
As we will see in Game 7, the positions that arise are very flexible. They allow both players to plan their strategies and choose between different pawn structures in the opening. Nevertheless, great care is needed, since the real battle will begin soon.
Various plans
After 6...♘a6, White can choose between three main possibilities:
1) The frontal attack
White can avoid Black’s threat of ...e7-e5 by deciding on the typical sharp frontal attack 7.e5.
In some modern books this is presented as the main line for White. But even though it hampers Black, the advance may be too hasty in general terms.
2) Classical development
In my opinion, it is more natural for White to first finish his kingside development with 7.♗e2, also analysed by Vaisser in Yearbook 78, but with different ideas. It allows Black to pursue his main idea 7...e5!.
This is a tactically important position with many possibilities for both sides.
3) A better square
After the analysis of the first two options, I am beginning to feel that the f1-bishop is better off on square d3: 7.♗d3!, intending 7...e5 8.fxe5 dxe5 9.d5, when 9...♘c5 is less effective, since the e4-pawn is well defended.
The Battle of Waterloo
Both modern and earlier theory offer as Black’s best solution to this problem the ‘pseudo-counterplan’ 7...♗g4 8.♗e3! ♘d7 9.0-0 e5!? 10.fxe5 c5!.
A colourful position! Now the fight can begin. In a way it is very similar to the battles from the times of the Roman Empire to the age of Napoleon Bonaparte. The pawn legion attacks, and behind it are the minor and the major pieces.
But now a remarkable move: 11.♗e2!. The books have hidden this strong move from the readers. One victim of these books was the black player in Game 8 of this chapter. After that game, Lopez Martinez claimed that 11.♗e2! ‘did not exist’ as it wasn’t in ECO or any other book.
KEEP IN MIND
Some of the exciting games in this chapter are excellent illustrations of the spirit of the Four Pawns Attack, according to the motto: If you don’t beat me, I will destroy you!
In this variation it is the white pawns that are the main actors.
The young Garry Kasparov.
Four Pawns Attack – Games
The bishop capture 8...♗xe6
If you don’t beat me...
At the start of our games collection, we analyse an historic battle that demonstrates the attacking potential of the Four Pawns. A young Garry Kasparov defends with the black pieces.
Game 1
Jacob Murey
Garry Kasparov
Moscow 1976 (7)
1.d4 ♘f6 2.c4 g6 3.♘c3 ♗g7 4.e4 d6 5.f4 0-0 6.♘f3 c5 7.d5 e6 8.dxe6!? ♗xe6
This recapture develops the passive bishop, and keeps the e-file half-open for activity.
The other option is 8...fxe6, which we shall analyse in Games 3-5.
9.♗d3!
The bishop goes to the important d3-h7 diagonal, where it will help both the e4 and f4-pawns and the pieces in the upcoming attack. This is one of the critical moments of this variation. Black must quickly look for some sort of effective counterplay, otherwise he will be in danger.
9...a6
Preparing the advance ...b7-b5!? but losing time for development.
The pin 9...♗g4, avoiding f4-f5, will be analysed in the next game.
10.f5!
A typical Four Pawns Attack.
Of course White could continue his development with 10.0-0!? first.
10...♗d7 11.0-0 ♗c6
In this game the young Kasparov played very slowly.
WEAPON:
.
12.♕e1!?
The queen heads for the kingside.
12...♘bd7 13.♕h4! ♘e5
Black tries to put up a block in the centre, but this is not enough.
14.♘xe5 dxe5 15.♘d5
We can now see the fruits of both sides’ opening play. Black’s position is very uncomfortable and he lacks counterplay, whereas White is prepared for the attack. Threats like 16.♗g5 are very serious.
15...♗xd5
.
16.exd5 ♘h5
16...e4 17.♗e2!?↑.
17.♗g5!
Without much effort White has achieved a nearly decisive advantage, and the final attack merely requires precision.
17...♗f6
17...f6? 18.fxg6!.
18.fxg6! fxg6 19.♖xf6! ♖xf6 20.g4!
The climax of the game. A few more moves and it seems White will be able to celebrate the victory.
20...h6
The only defence.
EXERCISE: What is the winning move for White?
21.♗xg6?!
A pity. Probably IM Murey made a mistake in his calculations, or it was simply a conceptual error. He chooses to continue the attack but then makes several tactical mistakes, allowing the talented Kasparov to come back into the game.
The simplest and strongest was 21.♗xf6! ♕xf6 22.♕xf6 ♘xf6 23.♗xg6 ♘xg4 (23...b5 24.♗f5 bxc4 25.♖d1!+–) 24.♖e1 with a practically winning ending for White.
21...hxg5 22.♕xh5 ♕e7 23.♗f5 ♕g7 24.♖f1?!
.
24...e4
Now Black has serious counterplay.
Interesting was 24...♖h6!? 25.♗e6+ ♔h8 26.♕f7 e4! 27.♕xg7+ ♔xg7 with a quite complicated ending.
25.♕h3 ♖e8 26.♕e3 b6 27.♖d1 ♖d6 28.♖d2 ♖e7 29.♔g2 ♔h8
Kasparov puts his pieces on the dark squares to defend against White’s light-squared bishop.
29...♔f8!?.
30.♖e2
After you have lost the initiative it’s very difficult to find a good plan.
30.♗e6!?.
30...♖h6
After a prolonged defence, Black slowly but surely starts harassing the white king.
31.♔f1 ♖e8 32.♖d2 ♕e5 33.♕xg5
33.d6!?. All seems well, but...
33...♖h3! 34.d6?
His last chance was 34.♕g6!? e3 35.♖e2, keeping the balance.
34...e3! 35.♖e2 ♕xd6 36.♔e1 ♖d8 37.♗c2
EXERCISE: Find the win for Black.
37...♕g3+!
Kasparov never gives you a second chance.
38.♔f1 ♖f8+ 39.♗f5 ♕f3+ 0-1
This exciting game is an excellent illustration of the spirit of the Four Pawns Attack: If you don’t kill me, I will destroy you!
Attacking with soldiers
The following game is a good example of how White’s attack on the kingside can be developed.
Game 2
Viktor Moskalenko

Lluis Maria Perpinya Rofes
2361
Barcelona rapid 2002 (3)
1.d4 ♘f6 2.c4 g6 3.♘c3 ♗g7 4.e4 d6 5.f4 c5 6.d5 0-0 7.♗d3 e6 8.dxe6 ♗xe6 9.♘f3 ♘c6
9...♗g4!? to avoid the option of f4-f5.
10.0-0
In my opinion, this is the correct move. The main alternative is 10.f5!? with complex play.
10...♗g4 11.h3! ♗xf3 12.♕xf3
This is the critical position of the variation. White’s basic plan is to prepare the advance f4-f5! and develop the initiative further with the moves ♗e3-f2-h4 and ♘d5 with strong pressure on f6.
12...a6
Garry’s old idea, preparing ...b7-b5.
WEAPON: Most popular is 12... ♘ d4 13. ♕ f2 ♖ e8 14. ♗ e3 (less strong is 14.f5 because of 14... ♘ d7!? with counterplay) 14...a6 15. ♖ ae1! and White’s position is very solid:
A) Black can complicate matters with 15...b5!? 16.cxb5 ♘xb5 (16...axb5 17.♗xd4!) 17.f5!↑ ♘xc3 18.bxc3 ♘xe4? 19.♗xe4 ♖xe4 20.fxg6 fxg6 21.♕f7+ ♔h8 22.♗h6!+–. In general we see that White is better prepared for the complications;
B) Or 15...♖b8 16.f5 ♘d7 17.♔h1 ♘e5 18.♖d1 b5 19.cxb5 axb5 20.f6 ♗f8 21.♗xd4 cxd4 22.♕xd4 b4 23.♘d5+– Moskalenko-Andriasyan, playchess.com 2005;
C) 15...♘d7 (a waiting strategy) 16.♔h1! (the king leaves the g1-d4 diagonal, nipping Black’s counterplay in the bud) 16...♔h8 17.♖d1! (the e4-pawn is well protected, so the rook goes to the d-file) 17...♘b8 (too slow) 18.e5!? (a typical break. Also possible is 18.f5!?) 18...f5?! (the main idea was 18...dxe5 19.f5 ♘d7 20.♗b1!? with good attacking chances) 19.exf6 ♗xf6 20.f5!→. White has completed his plan and he has a huge advantage, Moskalenko-Munoz Pantoja, Badalona 2001.
13.♗e3 ♕e7
Other possibilities give White good prospects:
Moskalenko-Barlov, Maspalomas 2002;
B) 13...♖b8 14.♖ad1 ♕a5 15.♕f2!↑ Moskalenko-Komljenovic, Burjasot rapid 2001;
14.♖ae1!
White’s development is completed and he is ready for the final assault.
14...♖ae8 15.♔h1!
The last preventive measure that avoids Black’s counterplay on the d4-g1 diagonal.
15...♘d4 16.♕f2 ♕d7 17.f5!
The attack begins.
17...♕c6 18.♕h4!
From here the queen operates more effectively.
18...b5
It’s too late for serious counterplay.
19.♗g5!
White’s domination is obvious. The initiative progresses automatically.
19.♘d5!?+–.
19...♘d7
If 19...b4, 20.♗xf6 ♗xf6 21.♕xf6 bxc3 22.bxc3, winning the knight.
20.f6!
This advance of White’s fourth pawn locks Black’s King’s Indian bishop in a neat prison.
20...♗h8 21.cxb5 axb5 22.♘d5! ♘e5 23.♗b1 ♖e6
EXERCISE: How to continue the attack with white?
24.♕h6!
Looking for an immediate mate.
.
24...♖fe8 25.♖f4!
Threatening 26.♖h4.
25...♘g4!?
The last stand is always made with tactics. On 25...♘d7, 26.♖h4 ♘f8 27.♘e7+ wins.
26.♖xg4!
26.hxg4? ♕xd5! 27.exd5 ♖xe1+ 28.♔h2 ♖xb1∞.
26...♘f5
26...♕xd5 27.♖h4!+–.
27.exf5 ♖xe1+ 28.♔h2 ♕xd5 29.fxg6 fxg6 30.♗xg6! 1-0
This game was quite clear-cut!
The flexible recapture 8...fxe6
The anti-theory-model
It must be understood that in the Four Pawns, White has a very strong centre and he must use this factor to dominate. In addition to this, there are good possibilities of a strong attack on the kingside.

WEAPON: 6. ♗ d3 c5 7.d5 e6 8.dxe6 fxe6 9. ♘ ge2!?.
analysis diagram
Moutousis-Markidis, Greece tt 2010. White controls the key central squares e4-d5.
6...c5 7.d5 e6 8.dxe6 fxe6!?
This continuation is more flexible than 8...♗xe6.
9.♗d3!
As in the previous line, this is the most active placement for the bishop.
9...♘c6
This seems natural, but there are several alternatives:
, attacking the weak d6-pawn, Moskalenko-Nataf, Villa Salou 2003.
WEAPON: Or 9... ♘ h5, with the same idea to take on f4: 10.g3 ♘ c6 (10...e5? 11.f5!) 11.0-0 b6 12. ♗ e3 ♗ b7 13. ♘ g5!.
analysis diagram
Black doesn’t have enough resources for active play: 13...♗xc3?! (≥ 13...♕e7 14.♕g4!? ♘d4 15.♘b5!↑) 14.bxc3 ♘g7 15.♕g4→ h6 16.♘f3 ♕e8 17.♕h4 h5 18.♕g5! ♘e7 19.♕h6+– Moskalenko-Vidarte Morales, Castellar 1999.
10.0-0
This is the main position of the Pawn Wedge Variation, because of the sheer number of possibilities here.
10...♔h8
Although this is recommended by theory, in my opinion it is a waste of time.
We shall examine the other alternatives in Game 4, and the most popular answer 10...♘d4!? in Games 5 and 6.
11.♘g5!↑
This manoeuvre is White’s main resource in the 8...fxe6 line.

Black’s most popular move, thanks to the famous old battle Christiansen-Kasparov. Black hopes to obtain a strong outpost on d4. This position holds many possibilities for both players.
11.♘xd4!?
A solid option that ensures a technical game.
Let’s also consider some other interesting plans for White:
WEAPON: More complicated is 11. ♘ g5!?. We already know that this is the most active move and that it forces Black to take action. But this time White has some interesting alternatives (as also in the main game). 11...e5! (this is a difficult position to understand, so we must continue playing!) 12.f5!? h6! (attacking White’s best piece):
A) The sacrifice 13.fxg6 doesn’t promise much because of 13...hxg5 14.♗xg5 ♗g4! (14...♗e6!?) 15.♗xf6 ♕d7! and there isn’t enough compensation for the piece, Toporov-Chehlov, St Petersburg 1998;
B) 13.♘f3!? leads to a balanced position: 13...gxf5 14.exf5 ♗xf5 15.♗xf5 ♘xf5 16.♘xe5= Molina Camacho-Catarineu Rabell, ICCF email 2012;
C) 13.♘h3 gxf5 14.exf5 b5!?. This Benko/Volga break is the key idea for Black. The complications that now start are related to strategic concepts. Brave players can accept the pawn with 15.♘xb5! (15.♗e3?! looks like a bad response. White should react with something more effective: 15...bxc4! 16.♗xc4+
