How can the rook ‘hurdle’ the knight and give a deadly check on d8? One needs to find the square where the knight will be most effective in the attack, even if that square is empty:

The knight is invulnerable (24...exf5 25.Qf6), and by comparison with other squares to which it could have jumped, from here it attacks g7 and e7.

It is clear that White needs to find a way to bring his queen to the h-file, but how can he do this, as his own bishop is in the queen’s way? The most convincing way is to remove the ‘unnecessary’ piece in such a way as to create additional threats:

The bishop puts itself en prise, but Black has no time to take it.

A) 25...Bb7 26.Qc4 Rd4 27.Nxf7+ Kg8 28.Qxe6+–;
B) On 25...fxg6, there follows 26.Qe4 or 26.Qg2.

Black resigned.

Having momentarily lost attention, Black has just carelessly doubled rooks on the d-file, another illustration of the fact that even the very greatest players sometimes make childish mistakes. In reply, there followed a simple blow, which became possible because of the insufficiently strong black position on the light squares.

Black resigned.

White has an extra exchange, but the Nd4 can be pinned, and the dark squares in his camp are not very strong. After the incautious:

it turns out that the opposition of the queens is in White’s favour.
It was essential to increase the pressure with 21...Bc5!. White would have to fight for equality: 22.b4! (he cannot solve his problems with 22.Rd2 Rd8 23.Qb3 (23.Rad1 Nxb2 24.Nc6+ Kc7 25.Rxd8 Bxe3–+) 23...Rxd4 24.Rxd4 Bxd4 25.Qxa4 Bxf2+ 26.Kh1 Qxb2 Black has the advantage, since the e5-pawn is also an object of attack) 22...Bxb4 23.Qb3 Bc3 24.Rac1 Bxd4 25.Qxa4 Bxf2+ 26.Kh1 Be3 27.Rc3 Rc8. The e5-pawn is weak, and Black’s chances are preferable.
