Jerome Gambit: Sometimes Enlightenment Does Not Come (Part 1)



When I finish a complicated game of chess I am often happy to turn it over to one of my silicon friends - nowadays, Stockfish 13 - to help me understand more about what was going on in the play, and how things could have been improved.

Sometimes, however, enlightenment does not come.

Take the following game. I am happy to share what I was thinking about, and I am willing to explain what I can about what was happening, but my computer friend let me down, with analyses that I too often could make no sense of at all. (That is part of the reason that I have linked to so many of my earlier games.)

Here we go.


perrypawnpusher - DaniyarManat

1 day/move, Chess.com, 2021


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


 4...Kxf7 5.Nxe5+ Kf8 

This move was mentioned in Alonzo Wheeler Jerome's first published analysis of his gambit in the April 1874 issue of the Dubuque Chess Journal. Black is not interested in gathering in more sacrificed material and keeps his King relatively safe.

6.Nxc6 dxc6 


Preventing White's d2-d4, and thus stronger than 6...bxc6 as in perrypawnpusher - badhorsey, blitz, FICS, 2011 (1-0, 26). 

7.O-O 

Or 7.d3 as in perrypawnpusher - fortytwooz, blitz, FICS, 2010 (1-0, 29); perrypawnpusher - Jore, blitz, FICS, 2011 (0-1, 16)perrypawnpusher - Conspicuous, blitz, FICS, 2011 (1-0, 13)perrypawnpusher -Lark, blitz, FICS, 2011 (1-0, 12); and perrypawnpusher - pitrisko, blitz, FICS, 2011, (0-1, 30).

Also 7.Nc3 as in perrypawnpusher - Ykcir, blitz, FICS, 2009(1/2 - 1/2, 11). 

7...Qf6 

Black puts pressure on the two long dark diagonals.

I have also faced

7...Bd6 in perrypawnpusher - Lark, blitz, FICS, 2009 (1-0, 18) 

7...Be6 in perrypawnpusher - CorH, blitz, FICS, 2009 (0-1, 74); perrypawnpusher - spince, blitz, FICS, 2013 (1-0); perrypawnpusher - PasayDefence, "Piano Piano" tournament, Chess.com, 2020 (1/2-1/2, 57); 

7...Ne7, in perrypawnpusher - smarlny, blitz, FICS, 2011,(1-0, 25); and 

7...Qh4 in perrypawnpusher - pitrisko, blitz, FICS, 2011 (0-1, 30) and perrypawnpusher - Al-der,"Italian Game Classic", Chess.com, 2019 (1-0, 26)

8.c3 

This was something new for me, but building a Jerome pawn center was not.

8...Ne7  9.d4 Bb6 

The Bishop's pin on White's d-pawn will weigh heavily in the play to come.

10.Nd2 Kf7 11.f4 Rf8 12.Nf3


White's broad pawn center just about balances out Black's material advantage, although the open lines for his two Bishops have to be attended to.

After the game Stockfish 13 rated the position as equal, and recommended instead of the text move, 12.a4 (I am not sure why) a5 13.f5 Kg8 (finishing castling-by-hand) 14.Nc4 Nxf5 (returning material) 15.exf5 Bxf5.

12...Bg4 

This is a tactical oversight. My first thought was to reply 13.h3 and to follow 13...Bxf3 14.Qxf3 with 15.g4 and some serious pawn action on the Kingside. After the game Stockfish 13 suggested that it was not impressed, giving 14...c5 as a counter that gave Black a clear advantage. Maybe it is my club player perspective, but it looks like 15.d5 then would leave White okay.

Anyhow, a second look - drawn by the fact that Black has only partly castled-by-hand -  gave me the correct response.

13.Ne5+  Kg8 14.Qxg4 Rfe8 15.f5 


15...Rad8 

This move threw me into a panic. Had I missed something? Had my opponent, in turn, missed something? Suddenly there seemed to be a lot more going on than my planned 16.Bg5.
