Jerome Gambit: What to Do Next?

Defending against the Jerome Gambit is more than finding the right move or the right line, it is also finding the right path out of a maze of complications. It is a given that Black has a "won" game after 4 moves, but, as always, he has to go on and win that game.

In the following game the defender quickly overestimates his chances and embarks on Quixotic attack that only looks scary.

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 

The Semi-Italian opening. Black wants to play it safe by keeping White's Knight off of g5.

4.Nc3 Bc5 5.Bxf7+ 

The Semi-Italian Jerome Gambit, leading to 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nc3 h6, etc.

I was a bit surprised to see Stockfish 8 recommend 5.Na4, leading to an equal game.

5...Kxf7 

Bypassing the piece leads nowhere: 5...Kf8 6.Bb3 Nf6 7.Nxe5 Nxe5 8.d4 Bb4 9.dxe5 Nxe4 10.Qd5 Black resigned, Wall,B - Guest2310139, PlayChess.com, 2014

6.Nxe5+ Nxe5 

It is always possible for Black to go weird in the line, but not necessarily successfully: 6...Ke6?! 7.Ng6 Rh7 8.d4 Nxd4 9.Nf4+ Kf7 10.Qh5+ Kf8 11.Ng6+ Kf7 12.Ne5+ Ke6 13.Qf7+ Kd6 14.Nc4+ Kc6 15.Qd5 checkmate, Wall,B - Guest638374, PlayChess.com, 2017

7.Qh5+ Kf8 

An improvement over 7...Ke6 8.Qf5+ Kd6 9.b4 Bd4 10.Nb5+ Kc6 11.Nxd4+ Kd6 12.Nb5+ Kc6 13.Qxe5 d6 14.Nd4+ Kd7 15.Qe6 checkmate, Wall,B - My10, PlayChess.com, 2017 and

7...Ng6 8.Qd5+ Ke8 9.Qxc5 Qe7 (9...d6 10.Qa3 N8e7 11.O-O Nh4 12.d4 Neg6 13.f4 Rf8 14.Be3 Bg4 15.Qb3 Rb8 16.f5 Ne7 17.Bf2 Nexf5 18.exf5 Nxf5 19.Rae1+ Kd7 20.Qe6+ Kc6 21.d5 checkmate, Wall,Bill - Mbgmx, Chess.com, 2010) 10.Qxc7 Nf6 11.O-O Kf7 12.Qc4+ Qe6 13.Qd4 Re8 14.f4 Qb6 15.Qxb6 axb6 16.e5 Nh5 17.g4 Nhxf4 18.d4 d6 19.exd6 Bxg4 20.Bxf4 Kg8 21.Bg3 Bh3 22.Rfe1 Rf8 23.Nd5 Rad8 24.Ne7+ Kh7 25.Nxg6 Kxg6 26.Re3 Rf6 27.Be5 Rfxd6 28.Bxd6 Rxd6 29.Rxh3 Rxd4 30.Rb3 Black resigned, Wall,B - Guest6602130, PlayChess, 2014

8.Qxe5 Qe7 

Putting Black's Queen on e7 or f6 is a standard defensive setup. The question is always: what to do next?

9.Qxc7 Nf6 10.d3 Ng4 



Attack! More reasonable, if less exciting, was 10...d6 11.Qxe7+ Kxe7 when the second player might have an edge. But, who wants an "edge" against a refuted opening? I mean, White has to be busted, right?

11.Nd5 Bxf2+ 

According to plan, even though Black should bail with 11...Bd6 12.Nxe7 Bxc7 13.Ng6+ Kg8 14.Nxh8 Kxh8 when White would have the advantage of a Rook and 3 pawns against a Bishop and Knight.

Things begin to look scary for White's King, but he will find his way to safety.

12.Kd2 Qg5+ 

13.Kc3 Qe5+ 

I don't know if Black overlooked the fact that this allowed the exchange of Queens, but he had a better move in 13...Qg6, even if it still left him worse off. 

14.Qxe5 Nxe5 15.Rf1 Ng4 



 16.h3 Black resigned



Black will lose a piece after all.
