Jerome Gambit: Remain Vigilant


Cartoon victorian balloonist

Sometimes the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) explodes decisively. Other times, White has to bide his time, waiting for a tactical opportunity. In the meantime, Black has so also remain vigilant, as a slip could prove fatal.

Such a slip occurred in the following game.

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.Bxf7+ 



4...Kxf7 5.Nxe5+ 

Komodo 10 actually prefers 5.d4 here. A recent example:  5...Qf6 6.dxe5 Nxe5 7.Qd5+ Qe6 8.Nxe5+ Kf6 9.Qxe6+ Kxe6 10.Ng6 Bb4+ 11.c3 Bc5 12.Nxh8 Nf6 13.O-O b6 14.Ng6 Ba6 15.Re1 Ng4 16.Be3 Bd6 17.f3 Nf6 18.Nf4+ Ke5 19.g3 Nh7 20.Bd4 checkmate, TCNB - Kawllie, 3 0 blitz, lichess.org, 2020.

White has also tried 7.Nc3 Bb4 8.O-O Bxc3 9.bxc3 d6 10.Qh5 Nf6 11.Qf3 Kg8 12.e5 dxe5 13.Qg3 Bf5 14.dxe5 Nh7 15.Ba3 Ng5 16.f4 Ne4 17.Qe3 Kh7 18.g4 Qd7 19.Rad1 Qe6 20.gxf5 Qxf5 21.Kh1 Rad8 22.Rde1 Nd2 23.Rf2 Nc4 24.Qc5 Ncxe5 25.Qxe5 Nxe5 White resigned, TheCuriousGreg - luiseduardomunoz1058, 10 0 blitz, Chess.com, 2020.

7...d5 8.e5 Bf5 9.O-O Bb4 



To keep White's Rook off of e1, but it allows the pawns to start rolling. 

10.g4 Be4 11.f5 Nh4 12.c3 Be7 13.Nd2 Bd3 14.Rf2 c5 15.Nf3 Be4 

Black still has control of things, but he has to remain vigilant.

16.e6+ Kf8 17.Ne5 Rh7 

Well, yes, White was threatening the Knight fork at g6...

18.Ng6+

If this were not a blitz game, White would probably have found 18.Nd7+ Ke8 19.Qa4!? Nf6 20.Nxf6+ Kf8 21.Nxh7+ Kg8 22.Bxh6+!? Kxh7 23.Be3 when he would have a Rook and 3 pawns for a Bishop and a Knight, which would be about equal in the middlegame (and maybe a slight bit better in an ending).

18...Ke8 

Black avoids the messy alternative, 18...Nxg6 19.fxg6+ Nf6 20.gxh7+ Bxh7 21.g5 hxg5 22.Qh5, but stumbles into checkmate from the other wing.

19.Qa4+ b5 20.Qxb5+ Black resigned



20...Qd7 21.Qxd7 checkmate is too painful to allow on the board.
