Here this sacrifice does not quite work, but it is not a losing move, as was believed by Vukovich, who analysed Greco's Sacrifice in great detail.

12...Kxh7 13.Ng5+ Kg6

[Black could have saved the game by playing

13...Kg8 14.Qh5 Ne5!

(14...Nf6 15.Qxf7+ Kh8 16.Re4!+-

; 14...Qf6 15.Qh7+ Kf8 16.Ne4 Qe5 17.f4 Qd5 18.c4 Qc6 19.Qh8+ Ke7 20.Qxg7 with attack.)

15.Rxe5 Bxe5 16.Qxf7+=

and White has to settle for a perpetual check. ]

14.h4 Rh8?

A mistake, but Black was in trouble already even after the best reply - 14...f5, as my analysis shows:

[14...f5 15.h5+ Kf6 16.Qxd4+ Be5 17.Qh4!

and Black cannot survive with his king exposed in the centre.]

15.Rxe6+ 15...Nf6
