Has anyone had positive results using the Ruy Lopez Norwegian variation nightingale gambit? There is a variation of the Ruy lopez that I have recently played and made two sacrifices and ended up with a very good game, and I wanted to know if anyone else could or have tried it? Here is the move order:

[FEN ""]
1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 b5
5. Bb3 Na5 6. Bxf7+


Then the continuation that was played was

[FEN ""]
1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 b5
5. Bb3 Na5 6. Bxf7+ Kxf7 7. Nxe5+ Ke8 8. Qh5+ g6
9. Nxg6


and black resigned. This was all played with a 2+0 time control so I saw this nice little gambit.
7...Ke8?? is a blunder for black. Instead, 7...Ke7!? is a much better try with the idea of weathering the attack with moves like ...Nf6 ...d6 and ...Qe8 (not necessarily in that order). Hard to prove that white is winning.
