I found this to be an interesting sacrifice, but I doubt it is strictly correct. White eliminates some of blacks king safety, but I still doubt it is entirely correct.
7...Ke8
What about this line:
7...Ke8 8.Qh5+
this should validate the initial sacrifice..

But Qh5 is not check if the king is on e6 ? Also Kxe5 is possible ?
Or do you think of another position?
Ke8, sorry. I'm referring to the position of the third image (I'm going to edit in the right way just now). What do you think about that continuation?
But that is the continuation in the post? Surely black has problems. It seems I did not put a picture in at this moment.
Well, I'll try to better explain.
The image I'm referring to is this one (position after 7...Ke8):
On this position a continuation could be: 8. Qh5+ g6 9. Nxg6 Bxg6 10. Qxg6+ Kd7. At this point Black still maintains the advantage of a piece, but White has regained a +1 and put black king exposed to attacks. In effect it is not sure about a real advantage for White after this, but I think he has a better position.
