This move ist the most natural one, but it seems too lose
immedeatly.

With this "trick" black protects his bishop.

15.Bc1 is the most nice one, but a computeranlaysis lets me doubt
it is the best one.
Anyway, the surprising 15.Bxh7!+ seems to win by force! Lets see:
15...Kxh7 16.Ng5+
A)16...Kg8 17.Rxd5 Bxd5 18.Qh5 Be4 19.Nxe4 is an easy win.
B)16...Kg6 17.Qd3+ f5 18.Qg3! Nxf4 19.Nxe6+ Kf7 20.Ng5+! Kg6 21.Nh3+ and white
wins.

No white can sacrifice again (phoenix):

16.Bxf6 Bxf6 17.Bxh7+ Kxh7 18.Qh5+ Kg8 19.Qxf7+ Kh8 20.Rde1 Bxg2 (otherwise
black has no answer to Re3-h3) 21.Kxg2 and white wins somehow.

Taking the knight leads to an immedeate loss, asa ny chessengine
can show.
