A simple but effective tactical blow – the black centre immediately collapses.
The decision taken is much more pragmatic than the move 16.h4!?±, which requires much more calculation.

Also bad was 18...Qe6 19.f4 Nxf4 20.Nxe5 Kh7 21.Qf3 Ng6 22.Nxg6 Qxg6 23.Re7+ Rf7 24.Rae1+–.
To all Black’s other woes is added the fact that he cannot bring out the Bc8.

The white pieces are idling on the queenside and the Na4 is attacked – this allows a crushing blow:
When taking on a4 last move, White probably counted only on 22...Bxd3 23.Rxd3 Rxa4 24.Qxa4 Nxb2 25.Qb3 Nxd3 26.Bxd3, with equality.
On 24.Qd2, there would follow 24...Bxd4 25.Kh1 Rxa4 – White is not mated, but Black completely dominates, as well as winning material.
The white pieces cannot come to the aid of their king, as they are too far away. The extra rook does not help, either.
