Jerome Gambit: A Flood on the Kingside

In the following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game, Black floods the Kingside with pieces - especially two Knights who harass the enemy Queen.

White's "Jerome pawns" help with rescue operations, and the first player prevails

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 

7.Qd5+ Ke8 8.Qxc5 Qe7 9.Qe3 d6 11.O-O Be6 

Black's casual decision about where to develop his Bishop - where else? - prompts an immediate and predictable response by White. Black's advantage is small.

12.f4 Ng4 

Signaling the start of an invasion on the Kingside. The attack on the Queen is often just a nuisance, as White has defensive capabilities.

13.Qf3

Stronger was 13.Qg3, although White may have passed on that move, wanting to avoid 13...Qh4. It turns out that the exchange of Queens is not to be feared, however, as 14.Qxh4 Nxh4 15.f5 Bd7 16.Rf4 h5 17.h3 will win a piece.

13...Nh4  

Ganging up on the enemy Queen.

14.Qe2

It may not be intuitive - and, remember, this is a blitz game, so intuition plays a large part in move choice - but g3 was still where the Queen needed to move to.

14...d5 15.f5 Qc5+ 

The lichess.org computer recommends instead the remarkable 15...Bxf5 16.h3 Ne5 17.exf5 Nef3+ 18.Kf2 Qxe2+ 19.Kxe2 Nd4+ 20.Kd2 Rf8 21.Nc3 Nxg2 22.Nxd5 Kd7 with an even game. 

16.Kh1 

16...Bxf5 

Giving back some material, but the resulting discovered check will allow White to take even more.

17.exf5+ Kd7  18.Qxg4 Black resigned

Black's other Knight is hanging as well.
