15... Nb7 16.Nf1 Ne8!?
a useful, waiting move

17.Be3 a5 18.a3 Ra6 19.Qc1 Rba8 20.N3h2 Nd8 21.g4 g6 22.Ng3 f6!
a typical regrouping move for Black
23.Kg2 Nf7 24.Ra2 Qb8 ( axb4 25.cxb4 Bd8 26.Ne2 Qb8 27.Nc3 Bb6 =/+ )
25.Bb1 Bd8! 26.Rae2 Bb6 27.Bd2 axb4 28.axb4 Ra1 29.Qc2
now Black slowly brings his pieces to the kingside.

the time is ripe for a breakthrough!

42.Qg4 Be8! with the deadly threat of Be8-h5 then Bf3!

White's king is cut off while his bishops are helpless against the Black's passed pawns & the rook, so White resigned.
