White’s attack comes to a dead end after 35.Ne6+ Kg8 36.Qb8+ Qe8.
Another false trail is the tempting 35.Re6 Qf5 36.Qxf5 Nxf5 37.Bxf6, because of 37...h6!.
All of Black’s pieces are tied to the defence of something or other, and the only move that does not lose at once is to move out of one pin into another.

However, in this case, the winning path for White is already not so difficult:

The rook joins in the attack with decisive effect.

On 39...Nf6, the most effective move is 40.Nf8.

With play on both flanks. The rook easily outplays the knight, and White wins.
