Jerome Gambit: A Refutation A Mile Wide and An Inch Deep

Sometimes a defender may appear ready to deal with the Jerome Gambit, and might even start off looking prepared - but if that preparation is "a mile wide and an inch deep", it won't be enough.

Consider the following game.


Wall, Bill - Guest5643953
PlayChess.com, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.d4 Qh4 



This "pie-in-the-face" variation is another example of an early ...Qh4 by Black, which immediately challenges White to find a way to survive.

7.O-O Nf3+

Okay, this is kind of strange...

Black's 6th move was one of the strongest ways to meet 6.d4, by ignoring possible material loss and, instead, initiating a counter-attack; but this move looks like the second player is suddenly upset at having two minor pieces attacked, and so he decides to give one up.

8.Qxf3+ Nf6 9.dxc5 Qxe4



What a difference a few moves can make! Instead of being down two pieces, White is up a pawn.

The game is not over, but certainly there is no talk of a refutation any more.

10.Qb3+ d5 11.cxd6+ Be6 12.Qa3 Qxc2 13.Nc3 cxd6 



Here we have a subtle position. Material is even. White's advantage is the weakness of Black's pawn on d6.

Black hurries to protect the pawn, but this makes his position worse.

14.Bg5 Ne8 15.Qb4 Bc8 



There was less danger in 15...b6. Black has un-developed two minor pieces and dis-connected his Rooks.

16.Rae1 h6 17.Re7+ Kg6 18.Be3 



After the game Stockfish 8 showed a preference for 18.Bxh6!? but there was no need to chase complications after 18...gxh6 19.Qd4 Rf8 20.g4!? The text move is fine.

18...Rf8 19.Qd4 Qf5 20.Nd5 



White's pieces cooperate and close in on the enemy King. In the mean time, it is again relevant to point out Black's Bishop at home, blocking his Rook, at home. Black now develops the Bishop, but it is too late.

20...Bd7 21.Re4

Threatening 22.Ne7+, forking the Queen and King. 

21...Qh5 22.g4 Qh4 23.Ne7+ Kh7 24.g5 



It is a tossup as to which is in more danger, Black's King or his Queen.

24...Qh3 25.Rh4 Qe6 26.g6+ Kh8 27.Rxh6 checkmate



Very nice!
