Jerome Gambit: First Blood

The Jerome Gambit has drawn first blood in the third round of the Chess.com Giuoco Piano thematic tournament. The game is not very exciting, however, and so games have been added in the notes to compensate.

Ouch. This kind of thing can happen, even in a slow game. Maybe the real world intruded. Maybe White's opening looked too innocuous to worry about in the early stages.

Winning Fast or Losing Fast?

Knowing your chess opening and what you and others have played previously is a powerful weapon in a contest.

Bill Wall's games show up over 365 times in The Database; he has a lot of experience with the Jerome Gambit - usually a whole lot more than his opponents. (As a reference, The Database's  over 51,500 games is useful, too.)

It is no wonder that the following game ends quickly. 

Wall,B - Guest4240618
PlayChess.com, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Kf6 

8.Qxc5

MrJoker and I have explored 8.d4: perrypawnpusher - whitepandora, blitz, FICS, 2008 (1-0, 41); mrjoker - Taj, Internet Chess Club 2009 (1-0, 9); perrypawnpusher - tjaksi, blitz, FICS, 2013 (1-0, 16); and perrypawnpusher - alvarzr, blitz, FICS, 2014 (1-0, 21).

8...d6

Not 8...Qe7 9.Qf5#  perrypawnpusher - zsilber, blitz, FICS, 2010. 

9.Qc3+

As opposed to the retreat 9.Qe3 seen in  perrypawnpusher - useche, blitz, FICS, 2010 (1-0, 22); perrypawnpusher - wbrandl, blitz, FICS, 2011 (0-1, 28); MrJoker - ipon, Internet Chess Club, 2011 (1-0, 33); and MrJoker - vicwill, Internet Chess Club 2011 (1-0, 12).

Now Bill is on his own, as there are no other examples of this move in The Database; but his opponent immediately helps him out.

9...Ne5 10.f4 Black resigned

Lost in the Maze; Then Just Lost

If, occasionally, both my opponent and I get lost in the maze of the Jerome Gambit, I feel reassured that it is my maze, and that I will still be able to find my way out, safely.

perrypawnpusher - tjaksi
blitz, FICS, 2013

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6

7.Qd5+ Kf6 

Alert! Possible trouble on the d8-h4 diagonal!

8.d4 

Interestingly enough, Houdini shows about a half-pawn preference for 8.Qxc5 over the text. That is not immediately obvious, although both  MrJoker and I have generally had success with that move - perrypawnpusher - zsilber, blitz, FICS, 2010 (1-0, 9); perrypawnpusher - useche, blitz, FICS, 2010 (1-0, 22); perrypawnpusher - wbrandl, blitz, FICS, 2011 (0-1, 28); MrJoker - ipon, Internet Chess Club, 2011 (1-0, 33); and MrJoker -vicwill, Internet Chess Club, 2011 (1-0, 12).

8...h6

My opponent responds to the perceived threat. The computer prefers 8...Bb4+ 9.c3  and then 9...Ke7, allowing for the Black Knight to intervene at f6, e.g. 10.Bg5+ Nf6 when White will recover one of his two sacrificed pieces, but Black will still have the advantage.

Instead, 8...Bb4+ 9.c3 c6 was seen in perrypawnpusher - whitepandora, blitz, FICS, 2008 (1-0, 41); while 8...d6 9.Bg5 checkmate, from mrjoker - Taj, Internet Chess Club, 2009 also has to be mentioned.

9.Qxc5 N8e7 10.e5+ Kf7 11.Qc4+ Kf8 12.0-0 b6 

Black is preparing to take advantage of White's pieces on the a6-f1 diagonal. It was probably better to play the straight-forward 12...d5. 

13.f4 a5 14.f5 Ba6 

Much to my opponent's delight, I have fallen into his trap: the Black Bishop skewers my Queen. However, I've suggested in "BSJG: Don't Try To Out-Think Me", and here is another case of that. Instead, after the game Houdini recommended the related 14...Nxe5 15.dxe5 Ba6 when 16.Qe4 Bxf1 17.Kxf1 d5 18.exd6 cxd6 19.Nc3 d5 would be about equal, White having a pawn for the exchange.

While Black was planning his maneuver, I used my moves to allow a discovered check.

15.fxg6+ Ke8 16.Qf7 checkmate

Pay Attention

Even when facing a refuted opening such as the Jerome Gambit, Black must pay attention and remain serious until the point has been secured. If he simply "plays moves", expecting the game to win itself, he runs the risk of taking too many chances and winding up on the wrong side of a miniature.

MrJoker  - vicwill
blitz, 2 12, Internet Chess Club, 2011

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 

7.Qd5+ Kf6 

This is taking a bit of an unnecessary risk.

8.Qxc5 

Or the eyeblink game: 8.d4 d6 9.Bg5 checkmate, mrjoker - Taj, Internet Chess Club, 2009. 

8...d6 

Another quickie: 8...Qe7 9.Qf5 checkmate, perrypawnpusher - zsilber, blitz, FICS, 2010. 

9.Qe3 Ne5 

Another idea is 9...N8e7, e.g. 10.d4 Kf7 (10...c5 11.dxc5 Qa5+ 12.Nc3 Qxc5 13.Qf3+ Ke6 14.0-0 Ne5 15.Qh3+ Kf7 16.Qh5+ N7g6 17.Be3 Qb4 18.f4 Nc4 19.f5 Nxe3 20.fxg6+ Kg8 21.gxh7+ Rxh7 22.Qe8 checkmate, perrypawnpusher - useche, blitz, FICS, 2010) 11.0-0 Rf8 12.f4 Kg8 13.f5 Nh8 14.Nc3 c6 15.Qg3 d5 16.f6 Neg6 17.fxg7 Kxg7 18.Be3 Rxf1+ 19.Rxf1 Nf7 20.Qf3 Ng5 21.Bxg5 Qxg5 22.Qf7+ Kh6 23.exd5 cxd5 24.Nxd5 Bg4 25.Nf4 Rf8 26.Qxb7 Rxf4 27.Qxa7 Rxf1+ 28.Kxf1 Qf4+ White resigned, perrypawnpusher - wbrandl, blitz, FICS, 2011. 

Rybka suggests 9...Kf7. 

10.d4 Ng4 

Equally dismal was 10...Nc4, i.e. 11.Qg5+ Kf7 12.Qxd8 b5 13.Qxc7+ Ne7 14.a4 b4 15.Qxc4+ d5 16.exd5 Nxd5 17.Qxd5+ Be6 18.Qf3+ Ke7 19.Bg5+ Kd6 20.Nd2 Rhe8 21.Ne4+ Kd7 22.Nc5+ Kd6 23.Qf4+ Kc6 24.0-0-0 Bd5 25.Na6 Kb6 26.Qd6+ Bc6 27.Nxb4 Rac8 28.d5 Red8 29.Bxd8+ Rxd8 30.Qxd8+ Kc5 31.Nxc6 a5 32.Qxa5+ Kc4 33.Qb4 checkmate, MrJoker - ipon, Internet Chess Club, 2011.

Black needed to retreat the Knight to c6.

Shortcut

The following game is from the recent collection sent to me by Louis Morin. It again shows that if your opponent becomes disoriented by the Jerome Gambit, the game can be over before he even knows it.
