If 36.hxg5 Rxc2, White loses not only the c4-pawn, but also that on g5.

On 1...Ne6?, White wins by 2.Rc2! (2.Ne7+ Kh8 3.Rc2 e4 4.Rh2 Qh5∞) 2...Qxa3 3.Ne7+ Qxe7 4.Rh2!.

Here too, a counterblow by the only relatively active piece saves the day:

If the queen is taken, White is killed by the presence of the pawn on f3, which prevents the rook being brought to the kingside with tempo.
After 2...gxh5 3.Rg1+ Kh8 4.Nh6, the threat of Rg8, followed by Nf7 mate is unstoppable.

But not 5...Qh5+?? 6.Qxh5 gxh5 7.Nh6+ Kh8 8.Rg1, and again Black has no defence against mate. 8...Rad8 9.Rg8+ Rxg8 10.Nxf7#.

With a draw by perpetual check.

The rook on the half-open b-file is firing into the air, but Black finds a way to make it useful:

From here, the rook can be brought not only to d5, but if necessary also to the kingside, because the white king is insufficiently protected by its pieces.

Faced with the unexpected, White misses the best defensive resource: 19.Qe4!, getting away from the attack from the black rook, and freeing the diagonal for her bishop. Then, there could follow 19...Nd3 20.Bd4, and here Black could choose between 20...Rd5, 20...Be5 and 20...Nc5 – admittedly, in each case Black’s initiative is fairly insignificant, and White should hold the balance.
