White quietly increases the pressure, whilst Black cannot coordinate his pieces.

There is now a threat of Bg4-h3, followed by Qd1-g4 and Rf2xf7. He also threatens the immediate Bg4xe6, and then Qd1-g4.

Black resigned, since after 26...fxe6, there follows Qd1-g4.

White exploits the opportunity of weakening a group of squares in the enemy camp, at a minimal material cost:

Now, the threat of the white queen appearing on h6 hangs over Black, as well as the possibility of a queen and bishop battery on the long diagonal.

This attempt to ‘plug’ the holes fails, because the weaknesses are irreparable; he cannot even get his rooks onto open files.

Black is so tied down that his queen and bishop lack even a single square each on the whole board.

White is in no hurry. Another general strengthening move was 31.Qf3, with the deadly threat of f4-f5.

When there is play on both flanks, two bishops usually cope easily with a rook. This case is no exception.

Black resigned.
