Jerome Gambit: Know This

How well do you know the Jerome Gambit? Certainly, the first four moves: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+. Likely the next two, as well, after 4...Kxf7 5.Nxe5+ Nxe5 and either 6.Qh5+ or 6.d4. As the following game illustrates, it is helpful to know a few more, critical, moves in a variation that guarantees that Black's game will be nasty, brutish and short.

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 Nf6 

Black clearly is unfamiliar with the Jerome Gambit, and, in attacking White's Queen, manages to quickly return both sacrificed pieces. The Database has 63 games with this position, with White scoring 73% - I am surprised that White doesn't do better. You should know the follow-up.

8.Qxe5+ Kf7 9.Qxc5 Nxe4 

Black's second gaffe makes things worse. Again, White should be able to spot the tactic right away.

10.Qd5+ Kf8 

Instead, 10...Kf6 was met by 11.b4!? in Vlastous - Orca, ChessManiac.com, 2016 (1-0, 16) 

11.Qxe4 Qf6 12.O-O d6 

13.Re1 Kf7 14.Qc4+ Kg6 15.Nc3 Rf8

Black still has fight in him, and envisions a counter-attack down the f-file, aimed at White's King.

White has other ideas.

16.Nd5 Qf7 17.Re7 Qf5 18.Qxc7 Qxd5 

What else? But, if it looks like Black can now no longer escape checkmate, you are right.

19.Rxg7+ Kf5 20.Rg5+ Ke4 21.d3+ Kd4 22.c3+ Kxd3 23.Rxd5+ Ke4 24.Qc4 checkmate

Why Play the Jerome Gambit?

I have posted on this blog various novelties and critical variations in the Jerome Gambit. I have shared Jerome blindfold games and games that are over after only a few sips of coffee. 

One of my favorite types of Jerome Gambit games is the one that announces, once again, "This is why I play the Jerome".

The following game - the latest from chessfriend Vlasta Fejfar - is a good example. White enters a line that he has played successfully before. Black is just getting comfortable in his defense, when he gets too comfortable - and a tactical shot turns the game into a miniature win by White.

vlastous - hobi

internet, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 

7.f4 Qf6 8.Rf1

The Database has 74 games, with this position. White scores 66%.

8...g6 

Vlasta has also faced 8...Nc6 in Fejfar,V - Vins, corr Czech Republic, 2015 (1-0, 23) and 8...Nd3+ in Vlastous - Kombe, internet, 2017, (1-0, 22). 

9.Qh3+ Ke7 10.fxe5 Qxe5 11.Qf3 Nf6 

Or 11...Qf6, as in vlastous - Marwan 86, internet, 2018, (1-0, 20) 

12.Nc3 d5 

Often this move is strong and liberating for Black - but not here, as White has a tactical answer. More prudent was 12...c6, as in Vlastous - Daboa, ChessManiac.com, 2016, (1-0, 42)

13.Qxf6+ Qxf6 14.Nxd5+ Black resigned

After White captures the Queen he will simply be 2 pawns up - 1 of them passed and protected. Black's "two Bishops" is not sufficient compensation, in either the Queenless middle game or the end game.

Jerome Gambit: Their Majesties

Here is the latest Jerome Gambit from Vlasta Fejfar, featuring two wandering Queens. White's Queen successfully attacks, while Black's Queen is a few steps slow in defending. In a surprise twist, the player who loses his Queen, wins the game!

vlastous - Marwan 86
internet, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4

This move is at least as old as D'Aumiller - AP, Livorno, 1878 (1-0, 19), appeared in 2 of the Jerome - Charles correspondence games in their 1881 match (both games incomplete), and appeared in 6 of the games in the legendary (to Jerome Gambit players, anyhow) Fisher-Kirshner - KnightStalker match of 1993.

4...Qf6 8. Rf1 g6 

We have seen a couple of Vlasta's opponents try other ideas:

8...Nd3+ "creatively returning a piece" in Vlastous - Kombe, internet, 2017, (1-0, 22); and

8...Nc6 "cold-blooded, but playable" in Fejfar,V - Vins, corr Czech Republic, 2015, (1-0, 23). 

9.Qh3+ Ke7 10.fxe5 Qxe5 11.Qf3 Qf6 

A common criticism of the Jerome Gambit is that White moves his Queen too early and too often. So far in this game, however, Black has kept pace with White.

Vlastous 2344 -Daboa 1799, Chessmaniac.com, 2016, (1-0, 42) saw the alternative, 11...Nf6.

12.Qe2 Qa6 

You can almost hear Black sigh "Enough, already!". The threat to exchange Queens is easily parried, though, and Her Majesty soon finds that she needs to get back in the fray.

13.d3 Ke8 14.Nc3 Ne7 15.Nd5 Qc6 

To protect against the threatened Knight fork at c7.

Black's best defense was 15...Kd8, when a typical messy game can continue with 16.Bg5 c6 17.b4 cxd5 18.bxc5 dxe4 19.Rf7 Re8 20.Qxe4 Qe6 21.Qxe6 dxe6 22.Rxh7 when White clearly has compensation for his sacrificed material, although the game is about even. (Who is more comfortable, though?)

16.Qf3 Nxd5 

Opening the e-file with the enemy Queen facing the King is pretty risky, but the best move, 16...Nf5, still loses. (And it turns out that White doesn't need the e-file after all.)

17.Qf7+ Kd8 18.Bg5+ Be7 

Black does not want to give up his Queen with 18...Qf6.

White decides to give up his.

19.Qf8+ Rxf8 20.Rxf8 checkmate

Very nice.

Jerome Gambit: Fighting The Annoying Defense

Chessfriend Vlasta faces the "annoying defense" and shows that while White does not have have a lot to work with, neither does Black. The game is an extended battle, after which the point is split. It is not clear who was satisfied with the result, the defender who nicked his half point against a refuted opening, or the attacker who "survived" playing a refuted opening.

Vlastous - NEWMAN 1982
Internet, 2017

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 d6

So annoying. Black gives back the piece and drains a lot of dynamism out of the position.

8.fxe5 dxe5 9.Qh3+ Ke7 10.Qg3 Ke8

Vlasta has faced 10...Kf7 as well, in Fejfar,V - Goc,P (1/2-1/2, 70); Fejfar,V - Chvojka (0-1, 32); Vlastous 2456 - irinat 2597, ChessManiac.com, 2016 (0-1, 38); and Fejfar,V - Svoboda/corr Czech Cup, 2016 (1-0, 30). 

11.Qxe5+ 

A small improvement over his earlier 11.Nc3 in Fejfar,V - Kyzlink, corr Czech Republic, 2015 (1-0, 20). 

11...Qe7 12.Qxe7+ Nxe7 

Now we have a battle between the extra two pawns and the extra piece in a Queenless middlegame. White cannot claim an advantage - but how is Black to win?

13.c3 Ng6 14.d4 Be7 15.Be3 Rf8 16.Rf1 Rxf1+ 17.Kxf1 b6 18.g3 Ba6+ 19.Kf2 Bd3 20.Nd2 Kd7

21.Bf4 Rf8 22.Ke3 Ba6 23.Nf3 Bb7 24.h4 h5 25.c4 Rd8 26.Rf1
Re8 27.b3 Bf6 

Black's Bishop pair is focused on White's pawn center which has a protected passed pawn.

28.e5 Be7 29.Ng5 Rf8 30.Rf2 Ba3 31.e6+ Kc8 32.Kd3 Nxf4+ 33.gxf4 Kd8 34.f5 Ke7 35.Rf1 Bd6 

Black seems unsure what to do. One idea, suggested by Stockfish 8, is to undermine the support of White's advanced passer, while exchanging Rooks, i.e. 35...g6 36.fxg6 Rxf1 37.g7 Rf8 38.gxf8=Q+ Kxf8. 

 36.Nh7 Rh8 37.Ng5 Rg8 38.Ke3 Bg3 39.d5 Bxh4 40.Kf4 c6 

Interestingly enough, this attempt at undermining support is not successful, in that it opens a line for White's Rook. The piece activity allows White to give up a second pawn.

41.d6+ Kxd6 42.Rd1+ Kc5 43.Ne4+ Kb4 44.Rd7 Bc8 45.Rxa7 b5 46.cxb5 cxb5 47.Rc7 Ba6 48.Rf7 Ka5 49.Ke5 Kb6 

50.e7 Re8 51.f6 gxf6+ 52.Nxf6 Bxf6+ 53.Rxf6+ Kc5 

Black decides to surrender his Bishop for the advanced passed pawn, submitting to the draw.

54.Rxa6 Rxe7+ 55.Kf4 Kb4 56.a4 Rb7 57.axb5 Rxb5 58.Kg3 Kxb3 59.Kh4 Kb4 60.Rh6 Rc5 61.Rxh5 Draw

Jerome Gambit: Winning is Not Annoying

Chessfriend Vlasta Fejfar of the Czech Republic has faced the "annoying defense" to the Jerome Gambit a number of times. In the following game, his most recent, he comes away with the whole point.

Vlastous - Idalgit
Internet, 2017

 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 d6 

This is also called the "silicon defense" because it is the choice of many computer chess programs. Black returns a piece and takes a lot of the action out of the position.

8.fxe5 dxe5 9.Qh3+ Kf7 

The text is about equal to 9...Ke7 which was seen in Fejfar,V -Goc,P, 2015 (1/2 - 1/2, 70),  Fejfar,V - Chvojka, correspondence, 2016 (0-1, 32) and Vlastous - irinat, Chessmaniac, 2016 (0-1, 38). 

10.Qh5+ Ke6 11.Qe2 

Stockfish 8 gives the practical suggestion 11.Qh3+ hoping for a draw by repetition. 

11...Qd6

Instead, 11...Ke7 was successful for Black in Wall,B - Alfil engine, Palm Bay, FL 2015 (0-1, 23); while 11...Nf6 was seen in Shredder 8 - RevvedUp, blitz 2 12, 2006 (1-0, 25) and RevvedUp - Yace Paderborn, blitz2 12, 2006 (0-1, 14).

12.Nc3 c6 13.Na4 Nf6 

A tactical slip that drops a piece. Black may have unconsciously decided that his opponent has finished moving his Queen.

14.Qc4+ Ke7 15.Nxc5 b6 16.Nd3 a5 17.Qc3 Ke6 

 

18.Qb3+ Black resigned

Perhaps a bit soon, but Black sees he will lose the b-pawn, and White's Queen will escape any danger, so the game may have lost its interest.

Jerome Gambit: Today, Hard Work

Chess games have been compared to a work of art created collaboratively by two people. That can especially be said about Jerome Gambit games where, with a little bit of "help" by Black, something spectacular can be created.

On the other hand, without that kind of "cooperation" White can find himself in for some hard work - like in the game below, from chessfriend Vlastimil Fejfar.

Readers are encouraged to play through the game, and see if they can build on Vlasta's efforts. 

Vlastous - irinat 
ChessManiac.com, 2016

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 d6

Ah, man, the "annoying defense" again. By returning the piece Black takes a lot of excitment out of the game - kind of like an over-boiled piece of meat. Computers love the line, as it gives Black an advantage; and computers are less likely to make the kind of "human" mistakes that work toward creating an exciting work of art. In this game, Black does a good job impersonating a computer.

8.fxe5 dxe5 9.Qh3+ Ke7 10.Qg3 Kf7 11.Qxe5 Qh4+ 12.g3 Qe7 13.Qxe7+ Nxe7

White has two pawns for his sacrificed piece, but the "Jerome pawns" are a long way from becoming a dynamic, attacking force.

14.c3 

Previously Vlasta played another difficult game with the interesting 14.h3, Fejfar,V - Chvojka, corr, Czech Republic, 2016, (0-1, 32). 

14...Bh3 15.d4 Bb6 16.Nd2 c5 17.Nf3 h6 18.Be3 cxd4 19.Bxd4 Nc6 20.O-O-O

20...Bg2 21.Rhg1 Bxf3 22.Rgf1 Nxd4 23.cxd4 Rhc8+ 24.Kb1 Kg6 25.Rxf3 Rc4 26.b3 Rxd4 27.Rxd4 Bxd4

The occupants of d4 and e4 suggest the rest of the story.

28.Kc2 Rc8+ 29.Kd2 Bf6 30.Rf2 Rd8+ 31.Ke2 Kf7 32.Rf5 Rc8 33.Kd2 Ke6 34.Kd1 Bg5 35.h4 Rc1+ 36.Ke2 Bf6 37.Rb5 b6 38.a4 Rc3 White resigned

A valiant effort by White, but now his pawns are under too much pressure, and soon some will fall.

Jerome Gambit: Theory and Practice (Part 4)

In the following game, White confidently and patiently makes his way through the opening and middlegame, indifferent to his opponent's attempts to simplify - and, later, to look for dynamic chances. The endgame win is there; he just has to keep strolling until he gets there.

Vlastous - Daboa 1799
ChessManiac.com, 2016

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 Qf6 

8.Rf1 g6 9.Qh3+ Ke7 10.fxe5 Qxe5 11.Qf3 Nf6 12.Nc3 c6 

White's play was inexact after 12...Bd4 in Gary_Seven - Kevin the fruitbat, JG3 thematic, ChessWorld.net, 2008:  13.d3 Bxc3+ 14. Bd2 Bxb2 15. Rb1 Bc3 16. Bxc3 Qxc3+ 17. Kd1 d6 18. h3 Bd7 19. g4 Rhf8 20. d4 Qxf3+ 21. Rxf3 Nxe4 22. Rxf8 Rxf8 23. Rxb7 Bb5 24. Rxc7+ Kd8 25. Rxa7 Rf1 checkmate.

What happens next in the text is that Queens are exchanged and the sacrificed piece is returned for a couple of pawns, giving Black a small advantage. The game is not over at all, however.

13.Ne2 Rf8 14.d4 Bxd4 15.Bf4 Qxe4 16.Qxe4+ Nxe4 17.Nxd4 d5 

18.O-O-O Bg4 19.Rde1 Kd7 20.h3 Bf5 21.Bh6 Rf7 22.Nf3 Re8 23.g4 b6 

An odd choice by Black. He will have two pawns for his piece, a typical Jerome Gambit situation for White. Perhaps it was a slip, perhaps he saw that situation as more dynamic that a possible Bishops-of-opposite-colors endgame.

24.gxf5 Rxf5 25.Nd2 Ng3 26.Rxe8 Kxe8 27.Rxf5 Nxf5 28.Bf4 h5 

Black's extra pawns are more targets than attacking units, as White begins to show.

29.Nf3 Ke7 30.Ne5 Kf6 31.Nxc6 g5 32.Bc7 g4 33.hxg4 hxg4 34.Nxa7 g3 35.Nb5 Kg5 36.Bxb6 Kg4 

37.a4 g2 38.Bg1 Kg3 39.a5 Nh4 40.Nd4 Kf4 41.a6 Nf3 42.Nxf3 Black resigned

Jerome Gambit: Theory and Practice (Part 3)

Chessfriend Vlastimil Fejfar sent a couple more of his games. They fit in well with the current "Theory and Practice" theme.

Here is the first, which illustrates an important, if infrequent line, where Black's carelessness (who needs to analyze against the Jerome Gambit?) needs to be addressed right away, with an immediate advantage to White. Suddenly, a "funny" opening isn't funny any more.

Vlastous - Orca
ChessManiac.com, 2016.

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 Nf6

Despite developing a piece that attacks the enemy Queen, this move is an error. White needs to know the proper response and play it quickly, as it leads to a position where he is up a couple of pawns (not down a couple of pieces).

The Database has 56 games with this position, with White scoring 73%. (In club play, a 2-pawn advantage isn't always decisive. See "Blunder Table" for Geoff Chandler's interesting point of view.)

8.Qxe5+ Kf7 9.Qxc5 Nxe4 10.Qd5+ Kf6 11.b4 

I like this move, which is a TN.

Of course not 11.Qxe4 Re8.

White does not even need to win Black's Queen, but that alone would be enough to force resignation.
