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.

The Bg3 is the only piece defending the king. If it is lost, White risks being mated. This is what happens after...
In the game, Black chose the waiting move 55...Kh8, and after 56.Nf6 Qxe1 57.Bxe1, the position equalised out.
The bishops fire over the whole board, whilst the queen is ready to land a deadly blow from either side.
