Jerome Gambit: Jerome-Knight Gambit? Impatient Jerome Gambit?

The Two Knights Defense is one way of avoiding the Jerome Gambit - or is it? Some attackers find that the 4.Bxf7+ sacrifice is still useful, especially in a blitz game.

The Two Knights defense. 

4.Bxf7+ 

From an earlier post

I have looked at the Jerome Gambit-ish Two Knights Defense variation (Jerome-Knight Gambit? Impatient Jerome Gambit?) 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Bxf7+ a number of times, most recently in the series "Jerome Gambit: Facing Up to 4.Bxf7+ in the Two Knights" Parts 1, 2 and 3; and "Jerome Gambit: Jerome-Knight Gambit".

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Neg4 

Recently Black fell into a trap that we have seen before: 6...Ng6 7.e5 Nd5 8.Qf3+ Kg8 9.Qxd5 checkmate, Guest2712510835 - Guest4549590140, blitz, Chess.com, 2022. 

7.e5 Qe7 8.f4 d6 9.O-O dxe5 10.fxe5 Nxe5 11.dxe5 Qxe5 

Black has wisely returned one of his two extra pieces for White's central pawns. White will have to work hard to make something out of his chances.

12.Bf4 Qxb2 13.Nd2 Bc5+ 14.Kh1 Bd6 

Black repositions his Bishop, and in the process, surrenders his whole advantage. How can that be?

15.Bxd6 cxd6 16.Nc4 Qb4 17.Nxd6+ 

17...Kg6 

The safest response would be 17...Ke7, when 18.Re1+ Be6 19.Nf5+ Kf7 20.Nd6+ would lead to a draw by repetition.

Heading toward the center with something like 17...Ke6 would be dangerous, i.e. 18.Re1+ Kd7 19.Ne8+ Kc6 20.Qf3+ Nd5 21.c4, etc.

18.Qd3+ Kh6 

If 18...Kh5, then 19.Rab1 will force the win of the Black Queen.

19.Nf7+ Kh5 20.Rf5+ Bxf5 21.Qxf5+ Kh4 22.g3 checkmate
