The Blackburne Shilling Jerome Gambit

4...Kxf7 5.Nxe5+ Ke6 6.f4 

Supporting the advanced Knight, at the risk of allowing ...Qh4+.

The main line was seen in Wall - Ferny, PlayChess.com, 2018: 6.c3 d6 7.cxd4 dxe5 8.Qb3+ = Kf6 (8...Ke7) 9.dxe5+ Kxe5 10.Nc3 Nf6 (10...Be6) 11.d4+ Qxd4 (11...Kd6) 12.f4+ Kd6 13.Nb5+ Black resigned 

6...h5 

Interesting. Black, in turn, prevents a check by White's Queen. The Database shows that the line has scored 50% - 17 wins, 17 losses. 

Stockfish 15 recommends, instead 6...Qh4+ 7.g3 Qh3 8.Nf3 Nxf3+ 9.Qxf3 d5 with advantage to Black. 

7.c3 Nc6 8.Qb3+ d5

9.Ng6 

White goes for tactics. More solid would be 9.O-O.

9...Rh6 10.Nxf8+ White resigned 

White's resignation is a puzzlement.

It is not hard to imagine the game continuing 10...Kf7 11.Qxd5+ Qxd5 12.exd5 Nd8 13.Ne6 Nxe6 14.dxe6+ Rxe6+ 15.Kf2 Nf6 when White would be 2 pawns ahead - although Stockfish 15 (35 ply) rates the position about equal.
