Centre: the four squares in the middle
At a glance
The centre consists of the four squares in the middle of the board: d4, e4, d5 and e5. Aaron Nimzowitsch insists that you always keep an eye on these squares, even when the middle seems closed. From there your pieces reach both wings quickly. If you neglect the centre, you often face a sudden attack right in the middle of the board.
In short
Look at the middle of the board. There four squares make up a small square: d4, e4, d5 and e5. Nimzowitsch calls this smallest square around the midpoint the centre. A piece there reaches both sides of the board quickly.
Pawns in the middle are a strong weapon. When they advance, they drive away enemy pieces and disturb their development. That is why Nimzowitsch advises holding your own centre if you can do so without other disadvantages.
Even a closed middle is not calm. Nimzowitsch compares the centre to a restless region where a fight can break out at any time. Often a knight jump to a central square is enough, and the position opens up. He calls this jump an invasion of the centre.
From a long example game Nimzowitsch draws four lessons. Watch the centre, and control its important squares with several pieces. Do not move your pieces to a wing too early; he calls this a swing. If the pawns have disappeared from the middle, then at least occupy their squares with pieces.
For Nimzowitsch what counts is your effect on the centre, not the number of your pawns there. Pieces on central squares and lines aimed at the middle can also replace the pawns. How this works when you give up a centre pawn is explained in the article on the surrender of the centre.
Summarised by the editors in their own words. This is not a quotation.
Centre against wing
Nimzowitsch gives two guiding ideas for strategy: protect the centre with several pieces and centralise your pieces. According to him, whoever is strong in the centre has the better prospects. This is especially true when the opponent attacks on the kingside and you control an open file in the middle.
Nimzowitsch learnt this the hard way. At San Sebastian 1912 he attacked Rubinstein on the kingside and lost. The game cost him first prize. He called it the worst defeat of his career.
To play through
In Lesson 8 you get to know the four central squares. Lesson 39 shows a knight jumping into the centre. In Lesson 25 you answer a wing attack in the middle.
In Nimzowitsch – Ahues, pay attention to who controls the middle. In Nimzowitsch – Romi the white pawns advance in the middle. The queen in the centre helps them do it.
Today’s view
The fight for the middle is still regarded as a basic principle of the opening. You fight with pawns, but often also from a distance with knights and bishops. A knight on a central square that no enemy pawn can control any more is still regarded as a big advantage.
