Invasion of the center: the leap into the center

In short

Look at a white knight on c3. No black pawn controls the square d5. If the knight leaps there, it works in both directions, and only a piece can drive it away or exchange it. Nimzowitsch calls this leap into the center an invasion of the center.

Nimzowitsch explains the idea in the chapter on the center. The knights on c3 and c6 should not only stop enemy pawn advances in the center. If the opponent neglects something in the center, they should leap into it. According to him, a position that looks closed is often only seemingly closed.

Often it starts with a move that does nothing for the center. Many players swing their pieces over to a wing too early. Nimzowitsch warns against this, because then the opponent threatens an invasion of the center. It is better to play from the center outwards and bring your pieces towards the center.

A leap into the center often leads to an exchange. Afterwards a pawn may recapture, and the picture in the center changes. So check beforehand what remains after the exchange. If the pawns have disappeared from the center, Nimzowitsch advises at least occupying the squares with pieces.

Start with lesson 39. There you leap to d5 or d4 in games by Capablanca and Nimzowitsch. Lesson 25 shows how an answer in the center slows down a wing attack. In Réti – Nimzowitsch, a black knight occupies a square in the center that has become free.

Getting into the center in Nimzowitsch’s games

In Réti – Nimzowitsch, Black first deflects the white queen. After the exchange of queens, a black knight leaps to e4, right into the center that has become free. Soon a second knight stands on d4. Together they dominate the board, Nimzowitsch writes.

In the supplement to “My System”, Nimzowitsch praises an opening move by Sämisch. There a black knight breaks in to e4 very early. According to him, this early incursion found many imitators and proved very fruitful.

When the leap is not enough

A free square in the center is not automatically a gain. In Steiner – Nimzowitsch, Black deliberately leaves a hole on d5. In this way he stops the advance of the white d-pawn. The white knight does leap to d5, but White can only hold the square with sacrifices, Nimzowitsch writes.

Today’s view

Today people usually speak of a hole or a weak square in the center in such cases. A knight on such a square is still regarded as a big advantage if it can hold its ground there. But only checking the concrete position shows whether the leap really helps.
