Now Black gets rid of his weaknesses, while activating his rooks and preserving the h -pawn. He won on move 49.

Logically enough, a queen exchange can also be used as a defensive resource, putting an end to the opponent's attack. In the diagram position Black has some play on the light squares on the kingside, but:

White has found a safe way to increase his advantage.

Not the hasty 34.f3 Ng5 35.Kg2 Ne6.

And White won.

White is a pawn up, but with his queen on the other side of the board his kingside attack has come to a dead end.

With the queens off, the pawns on a4 and c3 will be easy targets for Black's rook, for example via b3 . You could also include this example under the heading 'eliminating the defender' .

Justifiably declining. Being a pawn up is of no significance here.
