Jerome Pawn Fall

The "Jerome pawns" - the one White obtains in exchange for his piece(s) - can be a powerful attacking or positional force. However, if White does not take care of his pawns, they can also become targets and the cause of his downfall, as in the following game.

ulla - abebe
milenrousoulski's mini-tournament, 
GameKnot.com, 2009

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+ 



The Blackburne Shilling Jerome gambit.

4...Kxf7 5.Nxe5+ Kf6 

Four years ago, in "BSG: Later on in the Discussion", I suggested that now, after 6.Nf3, the game would be equal. Shortly afterwards, I faced 5...Kf6 played by RVLY, a specialist in the line (see "Whose Territory Are We Fighting On?"), but after 6.c3 Kxe5 we transposed into more regular 5...Ke6 lines. GOH, a member of the Jerome Gambit Gemeinde playing at FICS, has faced 6.c3 Ne6 and 6.c3 d6. To date, The Database does not include a game with my suggestion 6.c3 Nc2+!?

6.Ng4+

There are 66 games with this line in The Database, played by the likes of Jerome Gambiteers GOH, HauntedKnight, MyGameUMove, stretto, Wall and yorgos. 

6...Ke7 7.c3 Ne6 

Or 7...Nc6 8.d4 d6 9.d5 Bxg4 10.Qxg4 Qd7 11.Qxd7+ Kxd7 12.dxc6+ Kxc6 13.0-0 Nf6 14.f3 h6 15.Be3 Be7 16.Nd2 b5 17.Nb3 a6 18.Nd4+ Kb7 19.Nf5 Bf8 20.Bd4 Re8 21.Rfd1 Re6 22.a4 g6 23.axb5 gxf5 24.bxa6+ Ka8 25.exf5 Re5 26.Bxe5 dxe5 27.Rd8+ Ka7 28.Ra5 Bc5+ 29.Rxc5 Rxd8 30.Rxc7+ Kb8 31.Rc6 Nd5 32.Rxh6 Nf4 33.g3 Rd1+ 34.Kf2 Nd3+ 35.Ke2 Nxb2 36.Rb6+ Black resigned, Wall,B - GYHZ, FICS, 2010

8.d4 h5

Or 8...Nf6 9.d5 Nc5 10.0-0 Ke8 11.Bg5 Be7 12.Nxf6+ Bxf6 13.Bxf6 Qxf6 14.b4 Na6 15.e5 Qg6 16.Qd4 b6 17.f4 Bb7 18.f5 Qg5 19.Nd2 c5 20.dxc6 Bxc6 21.Ne4 Qg4 22.Nd6+ Kd8 23.Qxg4 Black resigned, Wall,B - Darksquare, 15 0 game, Chess.com, 2010.

9.Ne5 Qe8 10.d5 

Unsettling the pawn front and ignoring the pawns left behind (e.g. at g2). White should have tried 10.0-0 followed by adding another pawn to the center with f2-f4. 

10...Nc5 11.Bg5+ Nf6 12.Qd4 d6 13.Nc4



White might have done better to try 13.Nd2 dxe5 14.Qxc5+ Kd8 15.Qe3, although Black would still have the advantage. 

13...Qg6

Striking back at the pawns.

14.Bxf6+ gxf6 15.g3 Qxe4+ 16.Qxe4+ Nxe4 17.0-0


The g-pawn is safe, but Black will now unravel his position and make use of his extra material. White does not complicate enough to distract him.

17...Kf7 18.Re1 Ng5 19.Nbd2 Bg4 20.Re3 Bh6 21.f4 Nh3+ 22.Kg2 Rhe8 White resigned



There is still play in the game, even after the Rooks are exchanged, but with only a pawn for Black's piece, it would be all uphill for White.

Playable, if Black figures out the proper continuation...


Creativity in chess has its place, even in the following game, as long as it doesn't overstep its boundaries.

Fandral - LuigiBot
standard, FICS, 2013

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




4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bb4+ 7.c3 Bd6




The computer software LuigiBot (rated in the 1500s at FICS) comes up with an interesting maneuver that has also been seen in the past by Jerome Gambiteers Darrenshome, jfhumphrey, stretto, Sir Osis of the Liver, and HauntedKnight. It is playable, if Black figures out the proper continuation.

8.dxe5 Bxe5 

Missing the proper 8...Be7.


9.Qd5+ Kf6 10.f4 Qe7 


Black should bite the bullet, instead, and play 10...Bxc3+ 11.Nxc3 Ne7, when material would be even, and White would be a bit better due to more central control by the "Jerome pawns" and a safer King.


11.fxe5+ Kg6 12.0-0 Nh6 13.Rf3 Rf8 




Hoping to hold off the attack, but allowing mate.


14.Rg3+ Kh5 15.Qd1+ Rf3 16.Qxf3+ Kh4 17.Rh3 checkmate

Black: Winning the "Wrong" Way



After the previous game, I was pleased to come across the following Italian Four Knights Jerome Gambit. 

JMonson has played the Jerome Gambit at FICS for at least 5 years (scoring 58%). Here he runs afoul of a relatively rare counter-attacking idea. The whole line deserves further exploration.


JMonson - fischerJrSON

standard, FICS, 2013

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 5.Bxf7+ 




The Italian Four Knights Jerome Gambit.


5...Kxf7 6.Nxe5+ Nxe5 7.d4 Nfg4




A plucky move by Black - Let White choose which piece he wants to capture, I want to attack!


The Database has only 3 earlier examples: two wins for White and one draw, a misleading result.


8.dxc5


Here, Black lost on time in Apterygidae - Danialian, standard, FICS, 2011. There is not much to learn from that.


Houdini prefers 8.f3 for White, leaving Black with an edge after 8...Bxd4 9.Qxd4 Qh4+ 10.Kd2 Qf6 11.Ke2 d6 12.Nd5 c5 13.Nxf6 cxd4 14.Nxg4 Bxg4 15.fxg4 Rac8. Jerome Gambiteers might want to remember 8.f3.


8...Qh4 


Instead, 8...c6 was played in the up-and-down MyGameUMove - SoftBrutal, FICS, 2013: 9.O-O Re8 10.Nd5 b6 11.b4 bxc5 12.bxc5 Nf6 13.Nxf6 Qxf6 14.Qh5+ g6 15.Qxh7+ Ke6 16.Qh3+ Ke7 17.Qg3 Ba6 18.Bg5 Bxf1 19.Bxf6+ Kxf6 20.Kxf1 a5 21.f4 Nc4 22.Qg5+ Kg7 23.f5 Kf8 24.Qxg6 Rxe4 25.Qh6+ Kf7 26.Qg6+ Ke7 27.Qg7+ Kd8 28.Qg8+ Re8 29.Qg5+ Kc7 30.f6 Re5 31.Qg3 Nd2+ 32.Kg1 d6 33.Rd1 Rae8 34.cxd6+ Kxd6 35.Rxd2+ Kc7 36.Re2 Kd6 37.Rxe5 Rxe5 38.f7 Ke7 39.Qxe5+ Kxf7 40.Qd6 c5 41.Qc6 c4 42.Qc5 a4 43.Qxc4+ Kf6 44.Qxa4 Kf5 45.c4 Ke4 46.c5+ Kd3 47.c6 Ke3 48.c7 Ke2  when White ran out of time and Black had no material to mate, giving a draw. Many improvements are possible for both sides.


9.Be3


This just loses a piece.


Instead 9.Qd5+ Ke7 10.g3 (10.Qd4 Kf7 11.Bf4 is about equal) 10...c6 (10...Qf6 11.f4 Nf3+ 12.Kf1 Qd4 13.Qxd4 Nxd4 14.Nd5+ Kf7 Black would have an edge) 11.Qd6+ Kd8 12.gxh4 Nf3+ 13.Ke2 Re8 14.Kxf3 h5 15.Bg5+ Re7 16.Bxe7+ (16.Qxe7+ Kc7 17.Qd6#) 16...Ke8 17.e5 b6 18.Ne4 Ba6 19.Rad1 Rd8 Black resigned, in stretto - shutrick, FICS, 2007.


9...Nxe3 White resigned

Jerome Gambit Doctor


Periodically in this new year we will be looking at different lines in the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) and be providing ideas (and study material) which may deliver "first aid" or heavier "fixes" in situations where White's play has been injured.

Here is a game by HauntedKnight, a regular player of things Jerome. He has 144 games in The Database, scoring an over-all 49%, which is the over-all average for White in those 27,400 games. With the Jerome Gambit proper he scores 42%, which is comparable to the 43% of all Jerome Gambit games in The Database.


HauntedKnight - Josue

standard game, FICS, 2012

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.d4 Be7 




Josue, the higher-rated player, chooses a very reasonable, if unpopular line. The Database has only 12 games with this move, but White has scored only 38% against it.


7.dxe5


White avoids the ostentatious 7.f4 which brings a lot of visual excitement, but more "flash" than "bang": 7...Nc6 8.d5 Nb4 9.a3 Na6 10.0-0 Nf6 11.e5 Ne8 12.Qh5+ g6 13.Qh6 Bf8 14.Qh3 d6 15.e6+ Kg7 16.b3 Be7 17.f5 Nf6 18.Bb2 c6 19.c4 cxd5 20.Nd2 dxc4 21.Ne4 Nc5 22.Nxf6 Bxf6 23.Bxf6+ Qxf6 24.bxc4 b6 25.Qg3 Bb7 26.Qxd6 Rad8 27.Qf4 Rd4 28.Qe3 Re4 29.Qd2 Rd8 30.Qf2 g5 31.Rad1 Red4 32.Qf4 Rxf4 White resigned, wirerabbit - SimpleOne, FICS, 2007

9...Nh6


Black is planning something wicked, a threat that shows up in several of the above games. Probably his best move was 9...dxe5.


10.Nc3 


It is prudent to note here that White can take the draw with 10.Bxh6 gxh6 11.Qh5+ Kf8 12.Qf3+ Kg7 13.Qg3+ Kf7 14.Qf3+ Kg8 15.Qb3+ Kg7 16.Qg3+ Kf7, etc.


If White wants to play on, it would seem that 10.Qh5+ Nf7 11.exd6 followed by 12.Nc3 would be best.


10...Bg4 


The unhappy point: White will lose his Queen.


11.Qg3 Bh4 12.Qf4 Rf8 13.Qxf8+ Kxf8

Comeuppance


I have faced a number of defenders who fought back against the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 4.Bc4 Bc5 4.Bxf7+) by putting their light-squared Bishop on b7 and putting one or two Rooks on the g-file. My success made me lazy in the following game, and the result was not hard to predict.

The nice thing about being two pieces ahead is that you have many choices on how to give one back.

Black has played a number of alternatives, the first shown here being a bit too exotic:

White has three pawns for his sacrificed piece, and the game looks about even.

20.Rfd1 Rg8 21.Kh2 f5 22.e5 b6 23.Rf6 Rb7 24.f4 



A complete misunderstanding of the needs of the position. White's g-pawn is going to take a lot of heat. Black, too, can attack in the Jerome Gambit!

The Return of Jerome Gambit for Dummies (Part 8)

Continuing my search through The Database's 8-move games, chasing clues to the "essence" of the Jerome Gambit, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+, (or at least an insight into how it "works"), I came across a lesson (again) for White, written in a handful of games.

After all, 7...Qf6 could simply be an example of Black placing a strong piece on a strong square. Or he could be planning something...

The Return of Jerome Gambit for Dummies (Part 5)


Continuing my search for the "essence" of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), or at least an insight into how it "works", I discovered that 7-move wins by Black were not so much improvements in defense (after all, after accepting two sacrificed pieces Black needs merely to "hold on") as they were instances of White throwing away a Knight (see "The Return of Jerome Gambit for Dummies Part 2") , a Queen, or a King. Some examples of the last case are given as a warning for White to "pay attention".

A Remarkable Error


When you play blitz chess, "things happen." You make moves that you would prefer to un-make. You play games that you would prefer to un-play. When the Jerome Gambit or its relatives are involved, that usually only makes it worse.

4...Kxf7 5.Nxe5+ Ke8 6.Qh5+ g6 7.Nxg6 Nf6 8.Qe5+ Qe7



This is the 17th game in The Database with this remarkable error that combines automatic, stereotypical piece placement with moving a bit too quickly (and realizing it a bit too late). I notice that Jerome Gambit regulars such as GOH, Darrenshome, stretto, yorgos and MyGameUMove have all faced it.

Interestingly, White has won 15 games, drawn one and lost one.

Gloom and Doom

Although I have occasionally been accused of having the demeanor of Mr. Rogers on muscle relaxants, I do have times when I am serious, or even downright gloomy take the "Update: 8...Qf6" post, for example.

Here is another cautionary tale.

Teterow - geneve
lightning, FICS, 2011

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


4...Kxf7 5.Nxe5+ Nxe5 6.d4

This move, rather than 6.Qh5+, was originally Alonzo Wheeler Jerome's preference.

6...Bb4+


This is an odd move, but it reflects an inconvenient fact, that Black has many ways of dealing with the Jerome Gambit, including choosing which piece(s) he wants to return – and in what way.

The move deserves a look, if only because it has been played by dismissive humans ("sure, why not?") and calculating computers.

7.c3 Qh4


How's that for a kick in the head? Just when you were saying to yourself, "Well, at least he didn't play 6...Qh4!?"

By the way, as long as I am mentioning 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf6+ Kxf7 5.Nxe5+ Nxe5 6.d4 Qh4, it is necessary to correct and update some of what I wrote in "A Pie-in-the-Face Variation" about a year and a half ago.

Today The Database contains 167 games with the 6.d4 Qh4 line. That's 26 games less than I thought that I had in November 2009, but perhaps that is a result of subsequently cleaning up my databases.

Also, 50 of the current games – about 30% of the 6.d4 Qh4 line – are now human-vs-human encounters, as opposed to only 8 (4%) in the original post. White's scoring has dropped from 50% to 29% amongst humans, which is in the right direction, but it is the ridiculously high 74% for all of the games in The Database. (Again, that is the impact of computer-vs-computer games largely selected by the source for White wins.)

8.cxb4

The dynamics of the current position are very similar to that of the position without 6...Bb4+ 7.c3. What that means is that White's best move here after 7...Qh4 has to be 8.0-0. Rybka 3, given 5 minutes per move in "blunder check" mode, further suggested 8...Nc6 9.cxb4 Qxe4 10.b5 Nce7 11.Re1 Qf5 12.Re3 Qxb5 13.Nc3 Qb6 14.Qh5+ Qg6 15.Qc5 b6 16.Qxc7 Qc6 17.Qe5 d6 18.Qg5 h6 when Black has an edge (about 3/4 of a pawn).

I am not convinced that this is the best path for Black to take, however.

If I were playing the defense, after 6...Bb4+ 7.c3 Qh4 8.0-0. I would prefer the as-yet-unplayed 8...Ng4, answering 9.h3 with 9...Be7. Perhaps Rybka downgrades this line a bit because White can exchange Queens with 10.Qxg4.

Anyhow, the text move is very dangerous and Black takes charge.

8...Qxe4+ 9.Qe2

A bit better is 9.Kf1, covering the g2 pawn, but after 9...Qd3+ 10.Qe2 Qxe2+ 11.Kxe2 Nc6 Black is clearly better in an uncomplicated game. As it it, the game transposes into this line.

9...Qxe2+ 10.Kxe2 Nc6


11.Rd1 Nxb4 12.Na3 Nf6 13.Re1 Re8+ 14.Kf1 Rxe1+ 15.Kxe1 d5


16.Be3 Bf5 17.Nb5 c6 18.Nc3

A final slip. 

18...Nc2+ 19.Ke2 Nxa1 Black resigned


Looks like there is more work to be done on the 6...Bb4+ variation. With wins in The Database by Jerome Gambit Gemeinde members Darrenshome, HauntedKnight, jfhumphrey, stretto, Teterow, yorgos and, of course, Bill Wall – there is plenty of hope.

Don't go away -- It gets better



After an opening oversight shared with my opponent (I wondered why there were no other examples of his 6th move in The Database) the game goes on to some interesting attacking ideas. So, don't get upset and go away; the game gets better.

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6


The Semi-Italian Opening.

4.0-0 Bc5 5.Bxf7+

The Semi-Italian Jerome Gambit

5...Kxf7 6.Nxe5+ Kf8


In the Sorensen Variation (see "Battle Again") of the Jerome Gambit, this King move is playable, even laudible. However, in the Semi-Italian Jerome Gambit... 

7.Nxc6

Of course 7.Ng6+ would win at least the exchange, depending on if the Knight can extract itself.

I think I was patting the dog and telling her I was busy when I made this move... (That's my story and I'm sticking to it.)

7...dxc6 8.d3 Ne7

By transposition 8...Nf6 led to perrypawnpusher - vladchess, blitz, FICS, 2011 (½-½, 46) with the relevant continuation 9.Be3 Qe7 10.d4 Bb6 11.f3 Kg8 12.Nc3 Kh7 13.Qd3 g6

9.Be3

Rybka 3 prefers to preserve the Bishop with 9.c3 Bb6 10.d4 and a roughly equal game.

9...Bb6

Black does not want to open the f-file with 9...Bxe3 10.fxe3+  but his King could have safely gone to g8 (and even on to h7) maintaining an edge.

10.Nc3

Instead, 10.d4 kept White's dark-squared Bishop and kept the game balanced. Exchanging the Bishop with 10.Bxb6 cxb6 was seen in stretto - TommyN, FICS, 2008.

10...Kg8 11.Bxb6

Impatience. Again, the way to keep things level was with 11.d4, but the choice of one strategy over another is always easier to see after the game is over.

11...cxb6 12.f4 Kh7 13.d4 Bd7


Here we have a confrontation between the "Jerome pawns" and Black's extra piece. The game is about equal.

14.f5 Rf8

Black has neatly castled-by-hand.

15.Qd3 Rf6 16.g4 g5

This pawn move upsets the balance of the game. It would have been more prudent to simply return the Rook with 16...Rf8.

17.e5 Rf7

This move creates unnecessary grief. Again, after the Rook retired with 17...Rf8, White can try 18.Rae1 Be8 19.Ne4 Kh8 but he still has to be careful with his pawns, lest Black liquidate them by returning his piece. 

18.e6 Black resigned

Not only does White's e-pawn fork a couple of pieces, his f-pawn threatens to advance with a discovered check.
