18.Nb6!

This forces the exchange of the Bd6, which is blocking the d-file.

18…Nxb3+ 19.axb3 cxb6 20. Rxd6 Qe7

White’s next task is to force the exchange of the remaining black bishop so as to obtain access to the d7-square.

21.Qh5! Be6 22.Nf5!

22.Rxb6? would fail to 22…Qc5 but now there is a real threat of Rxb6.

22…Bxf5

22…Qc7? loses on account of 23.Nxg7!.

23.Qxf5 Rad8 24.Rd7

Of course not 24.Rxb6?? Rxd1+ 25. Kxd1 Qd8+.

24…Rxd7 25.Rxd7 Qh4 26.h3

Exchanging bishops in order to weaken a complex of squares

Whenever during a game it comes about that the pawns (on one wing or in the centre) are almost exclusively on the squares of a single colour, then the squares of the opposite colour tend to weakness. But as long as the defending side has at its disposal sufficient pieces to cover this Achilles heel, the square weakness is not usually decisive.

The weakness of the squares does not become significant until the attacking side manages to eliminate by means of exchanges the defending pieces.

The following classical example – which has been discussed in too one-sided a way in too many manuals – also shows, last but not least, the tactical resources (note for example the motif d4-d5!) with which the defender can avoid being ‘fixed’ on the weak squares:
