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.

[Black could have saved the game by playing
(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.)
and White has to settle for a perpetual check. ]

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.]
