This is Your Brain. This is Your Brain on the Jerome Gambit...

There's always something interesting about a Bill Wall Jerome Gambit game. The following game has several enlightening points, but the most enduring one for me is the sad career of Black's light-squared Bishop that never leaves home, and is hardly ever able to - a tell-tale sign that the second player is in trouble. 

Wall, Bill - Dad88, 2014

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 

The Semi-Italian Opening.

4.O-O Bc5 5.Bxf7+ 

The Semi-Italian Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.d4 

I was surprised to see that Houdini prefers this to 7.Qh5. Of course, Bill has played that, too. See Wall,B - Castro,S,, 2010 (1-0, 23) and Wall,B - Guest473534,, 2011 (1-0, 21).


Or 7...Bxd4 as in Wall,B - Merdiyev,F,, 2010 (1-0, 17), Wall,B -Foman,, 2010 (1-0, 16) and Wall,B -Ratebabb,, 2010 (1-0, 28).

8.dxe5 Ne7 9.Nc3 c6

Bill suggests, instead, a step toward castling-by-hand with 9...Rf8.


He also offers 10.Kh1 followed by 11.f4.


Casually giving the piece back, probably unintentionally.

11.Qf5+ Kg8 12.Qxg6 Qf8 13.Ne2 Qf7


As an alternative, Bill mentions 14.Qxf7+ Kxf7 15.Be3. It is worth extending that line one move further, with 15...Bxe3 16.fxe3+. White's advantage in material then consists of tripled, isolated e-pawns, but they help him dominate the board

analysis diagram

14...Kh7 15.b3 Rf8 16.Bb2 Qg6 17.Qd3 a5 18.Ng3 a4 19.Nf5 axb3

Black would have done better to open his position with 19...d5 20.exd6 Bxf5 21.exf5 Qxf5 22.Qxf5+ Rxf5, as Bill notes. 

20.axb3 Rxa1 21.Bxa1 Rd8 22.Nd6 

Keeping things clamped down.

22...Bc5 23.Rd1 

Or 23.Nxc8 Rxc8 24.Qxd7, but it seems a shame to relieve Black's light-squared Bishop of its misery. 


Making his own threat of 24...Rxf2. The alternative, 23...Bxd6 24.exd6 Re8 seems self-punishing. 

24.Nf5 Qe6 
25.h3 g6 26.Nd6 Bxf2+ 

Better says Bill, is 26...Rxf2

27.Kh2 Bc5  

Missing the line in the game that allows for winning simplification. His last try to hold on was 27...Qe7 28.Nxc8 Rxc8 29.Qxd7 Rc7

28.Nxc8 Rxc8 29.Qxd7+ Qxd7 30.Rxd7+ Kg8 31.Rxb7 Re8 32.Rc7 Re6 33.g4 Be3 34.Kg3 Black resigned

The end may be a ways off, but it is inescapable.

Another Delayed Jerome Gambit

In the following game Black's pieces do not know what to do with White's advancing pawns, and so decide to retreat and jump out of the way - leaving the field open for White's Queen.

Philidor1792 - bichara22
Casual Game Online chess portal http://ch (1), 2013

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Bb3 Bc5 5.Bxf7+

Another delayed Jerome Gambit, as in Philidor 1792 - guest1063, blitz 3 0,, 2013 (1-0, 37) and Philidor 1792 - guest3, 3 0 blitz,, 2013 (1-0, 22).

5...Kxf7 6.Nxe5+ Nxe5 7.d4 Re8 

Black'smove is reasonable, but there is only one other example in The Database, Cossyphus - HarryPaul, blitz, FICS, 2004 (0-1, 33)

8.0-0 Bd6 9.f4 Ng6 10.e5 Be7 11.f5 Nh4 12.Nc3 Ng8

The "Jerome pawns" advance, scattering all resistance.

13.Qh5+ g6 14.Qxh7+ Kf8 15.fxg6+ Black resigned
