The game of chess calls for shrewd analytical skills of positions coupled with calculations to gain control over the game. It is essential that good positional play should be entwined with calculations of moves and deployment of effective tactics assessing the overall position in the board. Having good control over the board positionally will not guarantee you any success over the opponent as long as you do not entwine the tactics effectively to gain control over the board. It is in this context that one should strive to be a good allround player instead of concentrating either only on his tactical skills or in positional factors.

In the following example, you will notice that having good positions will not lead to success as one silly error caused without giving importance to the opponent’s pieces, and due to paucity of time, ended up in losing the game from the winning position.

This is the position after 27 moves. It is the turn of the white to move now.

Position 1
White is a good player in positional chess and now, a cursory look at the board indicates that white has an extra pawn than black.  The game proceeded as follows :

28.    Rc1       h6
29.    Rc8+    Kh7
30.    Rc4       Qe5
31.    Rf4        Qc4

White, using his skills on positional chess has been making satisfactory progress.  The position after 31 moves is given hereunder:

Position 2
Not only is the white rook at f4 supporting the pawn at f2, the queen in b3 is threatening the black pawns at e6 and f7 and blocking their movement.

32.    Kh2    …..            Another good move from White in an attempt to develop his pawns with King’s assistance.

32.    …..        Kg7
33.    Rg4+    Kh7
34.    Rf4        Kg7
35.    Qb4       Qc2
36.    Kg2       e5
37.    Rg4+    …….            This is a wrong move from White that has exposed the pawn at f2.

37.    ……        Kg6            Black tries to capitalize on the wrong move by White.   He could have moved the King to h7 but instead preferred this move.

38.    Qxb6+    …….            White continues to attack with fervor considering the fact that time is running out, and Black tried to confuse the confused white by moving the king to the “f” file.

38.    …….    Kh5

This is the position at the board at the end of 38 moves.

3rd Position
39.    e4+    ……            This is the blunder on the part of White.  He did not assess the winning position correctly and out of confusion and time constraint, deprived himself of a winning move in Kh3 and by calling check on Black, exposed the white rook at g4, and literally threw the game.

39.    ……    Kxg4
40.    Qe3    Rd3
41.    Qxh6    Rxg3            After this White resigned accepting defeat.

This is a clear example of how confusion caused by the opponent and paucity of time can change the whole advantage into a loss.

For any aspiring chess player to grow up the ladder and achieve success, he or she should develop as a complete player having allround skills and not relying on any particular skill as positional play or tactical player.  Positional analysis and calculation of the moves and counter moves are very essential for the deployment of a good successful chess strategy or an effective chess tactics.

In Chess Opening: Control of Center – Part 1, we looked at two popular KP openings to understand how those resolved the tussle between White and Black for control of the center. Here we take a similar look at a common QP opening to realize the chess tactics involved in this case.

Nimzo-Indian Defense
The classical theories on the strategy of chess openings, as formulated by the first undisputed World Champion Wilhelm Steinitz (1836-1900), was further refined by Dr. Siegbert Tarrasch (1862-1934). These stressed the importance of center control by occupation or by direct application of pressure on those squares by using pawns, developing pieces to support that control, and playing to obstruct opponent’s plans in this regard.

It was Aaron Nimzowitsch (1886-1935) who challenged these conventional and fairly universal ideas with his own in My System, which was probably the most widely read book on chess theories. His system found expression in several openings that bear his name, and Nimzo-Indian Defense happens to be the most important among his hypermodern theories and very widely used in master games till today. It appears that the defense was first played in a Rubinstein-Alekhine game at Leningrad in 1914 (won by Black in 28 moves).

What is significant in this opening is that Black does not commit any pawn structure at the start, thus retaining considerable flexibility. Black exerts control on the center indirectly from a distance by use of his pieces and also undermining the influence of enemy pieces on the center.

Let us see how all this is accomplished.

 

nimzo-indian1
1. d4 Nf6   White wants to control the central square e5 and semi-central c5. Black applies pressure on d5 and e4 by the Knight (a direct control would need Black to play d5, which normally leads to Queen’s Gambit opening).
 
nimzo-indian2
2. c4 e6   White now counters Black’s pressure on d5 by his pawn move and Black uses his KP to strengthen his hold on d5.
 
nimzo-indian3
3. Nc3 Bb4   White develops his QN, adding to the pressure on d5 by his QBP and exerting a measure of control on e4. Black again goes the indirect route to nullify the influence of White QN on d5 and e4 by pinning it. Black also creates the possibility of exchanging his KB with White’s QN, surrendering the advantage of Bishop pair to create a liability of doubled pawn for White on c-file.
 

 

In this defense, Black generally puts his QB in fianchetto by playing b6 and Bb7, applying the Bishop’s influence on the long diagonal including the center squares d5 and e4 in harmony with his KN.

If Black exchanges his KB with White’s QN, his strategy will be to close the center to minimize White’s advantage of Bishop pair. You know that an open game gives a great advantage to player having two Bishops and obviously White’s strategy will be to go for such a game.

At this stage, 4. e3, a quiet looking move, is considered to be White’s most potent weapon against Nimzo-Indian Defense. 4. Qc2 (with the idea to retain Bishop pair without doubling of pawn) and 4. a3 (a venturesome continuation and forcing Black’s hand to play 4. … Be7 or 4. … Bxc3) are also playable. Kasparov used 4. Nf3 (a kind of wait-and-watch move) to considerable success against Karpov in their championship match.

To remain within the ambit of our article, we will consider the normal variation only.

 

4. e3 0-0   White consolidates his QP and goes for development by opening a line for his KB.
 
nimzo-indian4
5. Bd3 d5   White is building up his pressure on e4 and will aim to place his KP there. Black continues with his center control by advancing QP.
 
nimzoindian5
6. Nf3 c5   White KN increases his control on e5, but Black undermines the pressure by threatening White’s QP with his QBP.
 
7. 0-0   White has completed his initial development and in case of doubled pawn due to Black exchanging Bishop with Knight, White can hope to undo it if Black takes his QP. Otherwise White can capture with his Knight to position it centrally. Black does not have any problem in completing his development and his share of center offers many chances of counterplay.

 

In Chess Opening: Control of Center – Part 3, we will see how the another important QP opening viz. Queen’s Gambit Declined goes about the struggle for the center.

The theory behind all chess openings is to control the center comprising the squares d4, e4, d5 and e5, and the development of pieces that goes with it. Control of the center by one player helps him to position his pieces more effectively while thwarting the development of opponent’s pieces. You can easily imagine that such a control with its associated benefits can facilitate your win to a great extent.

This control can be achieved in three ways:

  • Firstly, by occupying those squares with your pawns and pieces.
  • Secondly, allowing your opponent to occupy the center and then attacking and undermining the position.
  • Lastly, exerting control from a distance by means of pieces like Knights and Bishops without directly occupying those center squares.

This control of a square is also known as ‘applying pressure’ on the square by threatening to capture any enemy pawn or piece that may venture to occupy the square.

In Chess Openings: the most popular ones, we tried to show you the most common first moves at the start of a chess game. But you must have noticed that the baker’s dozen of most popular types can ultimately lead to hundreds of different openings, going by the ECO codes that incorporate those opening moves. If you examine any of these openings through the moves that follow, the theme of center control will become apparent by the use of one of the three opening tactics described above.

To see how the different chess openings aim to achieve center control and their pros and cons, let us check four types which are related to the most frequent first moves described in Chess Openings: the most popular ones. Incidentally, two of these openings start with pushing the KP (1. e4) and the other two with QP (1. d4), so a fair representation is made!

We will examine with reference to the following openings:

1. e4-c5 (Sicilian Defense)
2. e4-e5 (Ruy Lopez)
3. d4-Nf6 (Nimzo-Indian Defense)
4. d4-d5 (QGD or Queen’s Gambit Declined)

However, since Ruy Lopez has been discussed earlier in Chess Opening basics: Ruy Lopez, we will examine the other three in this and the next article.

Sicilian Defense:
It has become the most popular choice at master level as it eminently suits a fighting player with Black pieces. As can be seen from the number of ECO codes, there are many variations possible, but here we will consider the Najdorf variation which has become very popular with players like Fischer and Kasparov going for it in a big way.

sicilian1
1. e4 c5   White wants to control the central square d5. Black in turn applies pressure on d4 against advance of White’s QP.
 
sicilian2
2. Nf3 d6   White creates his own pressure on d4 and also on e5. Black’s pawn move opposes this pressure on e5. Here, Black could also play Nc6 which would counter the White KN’s influence. Retaining a control on d5 is a key theme for Black in Sicilian defense in order to free his position by moving his QP to d5.
 
3. d4 cxd4   White does not want to lose initiative, so goes ahead with his QP advance and Black immediately captures the pawn to deny White the hold on the center squares.
 
sicilian3
4. Nxd4 Nf6   White recaptures and positions his KN on a center square. White gets control of half-open d-file while Black gets half-open c-file as also a pawn majority at center. Black now develops his KN threatening White’s KP and exerting pressure on d5.
 
sicilian4
5. Nc3   White counters Black’s plans by bringing out his QN which gives support to his e4 pawn and bolsters his hold on d5.
 
sicilian5
5. … a6  

 

For the first time, Black seems to have deviated from the struggle for the center through this defining move for Najdorf variation of Sicilian Defense. What is the idea behind this apparent deviation?

By this move, Black denies b5 square to White‘s Knights and KB. It also prepares for Black’s pawn move to b5 to start a Queenside action and positioning his QB to b7 from where it can bring pressure on d5 square and White’s e4 pawn.

After this, White may generally choose from the sharpest line with 6. Bg5 to quieter, positional games with 6. Be2, and others lying in between like 6. Be3, 6. f3, and 6. Bc4. But further analysis of all those moves will take us into a full discussion of Sicilian Defense, which was not the idea behind this article. We only wanted to show how any opening theory tries to achieve center control and if you understand the means and follow the principles, you will be in the right lines without a need to memorize too many moves!

In next two parts of Chess Opening: Control of Center, we will see how this is achieved in two popular QP openings viz. Nimzo-Indian Defense and Queen’s Gambit Declined.
