One Step Behind



My opponent's play was bold enough to give me trouble, and even if he did not solve all of the mysteries of the Jerome Gambit, he played a game which left me feeling constantly as if I were one step behind. 

 
perrypawnpusher - magza
blitz, FICS, 2011

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


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


7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Be6

This move provokes f2-f4 by White, but it is only the beginning of Black's sharp play.

10.0-0

Or 10.f4 as in mrjoker - Melbourne, blitz, ICC, 2008 (1-0, 38), mrjoker - tomnoah, ICC, 2009 (0-1, 42), perrypawnpusher - GabrielChime, blitz, FICS, 2010 (1-0, 33); perrypawnpusher - udofink, blitz, FICS, 2010 (1-0, 29), and perrypawnpusher - Kingsmeal, blitz, FICS, 2010 (0-1, 25).

10...Kd7



My opponent practically screams "Come and get me!"

Alternatives include 10...Qf6, as in perrypawnpusher - OverwiseMan, blitz, FICS, 2010 (1-0, 24); 10...Nf6, as in perrypawnpusher - dirceu, blitz, FICS, 2010 (1-0, 16) and perrypawnpusher - nmuffjgp, blitz, FICS, 2010 (1-0, 22); and 10...h6 as in MrJoker - pds1, ICC, 2011 (1-0, 28).

(All of the games referred to can be found in The Database.)


11.f4 N6e7 12.f5 Bf7 13.d4 Bc4 14.Rd1 Nf6


Black's pieces keep close watch on White's "Jerome pawns."

"Just a couple more moves," I told myself, "and I'll have an even game."

15.b3

Either 15.e5 or 15.Na3 might have been a tiny bit better.

15...Ba6 16.Nc3

A curious move.

I know that I did not play 16.e5 because I was worried about 16...Nxf5, but that was just poor "analysis", as 17.Qf3 wins back the sacrificed piece with advantage to White. Black does better to answer 16.e5 with 16...Ng4, and after 17.Qg5 he holds his own (or better) in the tactics on the Kingside.

Consistent was 16.c4 followed by 17.Nc3.

16...Re8

This move was my "opportunity", the one that usually comes knocking in the Jerome Gambit. Black's best was 16...Qf8 working against the line given concerning 15.e5. In fact, White's next move should be 17.e5.

17.Qg5 Rg8 18.e5 Nfd5


19.Bb2

Developing the Bishop, protecting the Knight, uniting the Rooks: and it all still feels too slow.

After the game, Houdini suggested 19.Nxd5 Nxd5 20.Qg4 (coming soon: c2-c4) with an edge for White.

19...h6 20.Qd2 Nxc3 21.Bxc3 Nxf5


Bleh. A score-and-one moves, and White has little to say about his position, while Black's pieces are beginning to glow again.

22.d5 Qe7

Possible, and better, was 22...dxe5

23.e6+ Kc8 24.Bb2 b6 25.c4 Kb7


Black has castled-by-hand on the Queenside, and his light-squared Bishop looks a little bit odd. White has his dark-squared Bishop on a strong diagonal, and a protected, passed pawn at e6.

Houdini gives Black only a slight edge, but the question is: Where will White get his play? Black's pieces are well-placed to defend against the one plan that suggests itself, infiltrating along the f-file to f7: 26.Rf1 Raf8 27.Rf2 g6 28.Raf1 h5.

26.b4

Opting to stir things up on the Queenside.

26...Bxc4 27.Rdc1

Making the same kind of mistake referred to in the notes to White's 16th move, concerning 16.e5. Here the right move was 27.Qf4, although after 27...Bxd5 28.Rxd5 g6 Black has returned his extra piece for some pawns, and is a pawn ahead.

White's e-pawn would be weak, not strong, and that would give Black the advantage in the long run.

White's game now just flows from bad to worse.

27...b5 28.a4 a6 29.a5 g6 30.Rxc4 bxc4 31.Rc1 Qg5 32.Qxg5 hxg5 33.Rxc4 Ne3

White's sacrifice of the exchange only means that he is now a Rook behind.

34.Re4 Nxd5 35.Rg4 Rae8 36.Rxg5 Nxb4 37.Rg4 Nd3 38.Bc3 Rxe6 39.Rd4 Nc5 40.Rb4+ Kc6 White resigned

Brilliant, but Not Sound

The title of this post was pronounced in the November, 1874 Dubuque Chess Journal about a move that transposed a game into a Jerome Gambit. It applies to Black's 7th move in the following game – which we have seen before, but should examine again.

MrJoker - Melbourne
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+ Ke6 7.f4 Nd3+


Ahhh... The joys of being two pieces ahead! There are so many ways for Black to return material.

Jerome Gambiteers should pay attention, as this admittedly unpopular move, nonetheless, leaves Black better.

8.cxd3

Take the Knight. Luke Warm - eddie43, Jerome Gambit Thematic Tournament, ChessWorld, 2010 continued instead 8.Kd1 Nf2+ 9.Ke2 Nxh1 10.Qe5+ Kf7 11.Qd5+ Ke8 12.Qxc5 d6 13.Qd4 Nf6 14.d3 Qd7 15.f5 Qf7 16.Nc3 Qh5+ 17.Kf1 Qxh2 18.Qg1 Ng3+ 19.Kf2 Ng4+ 20.Kf3 Qxg1 21.Kxg3 h5 22.Ne2 Qf2+ 23.Kh3 Qxe2 24.Bg5 Ne3 White resigned

8...Bd4 9.Qd5+ Black disconnected and forfeited

As you might guess, that is not the complete story.

Three days later the two opponents met again, and this time Black wisely retreated the Bishop. In the end, though, White prevailed in MrJoker - Melbourne, blitz, 2 12, Internet Chess Club, 2011: 8...Bb6 9.b3 Qf6 10.Qe8+ Qe7 11.f5+ Kf6 12.Bb2+ Kg5 13.Qxe7+ Nxe7 14.Bxg7 Rg8 15.f6 Ng6 16.h4+ Kh5 17.g4+ Kxg4 18.h5 Bd4 19.hxg6 hxg6 20.f7 Bxa1 21.fxg8Q Bxg7 22.Qxg7 d6 23.Qxg6+ Black disconnected and forfeited.

A couple of months later, White again benefitted from the hanging Bishop, in MrJoker - wikidguru, blitz, 2 12, Internet Chess Club, 2011: 8...Bd4 9.Qd5+ Ke7 10.Qxd4 Nf6 11.b3 d6 12.Ba3 Bg4 13.e5 Ne8 14.Nc3 Kf7 15.0-0 h5 16.Ne4 dxe5 17.fxe5+ Kg8 18.Qc4+ Kh7 19.Qf7 Qd7 20.h3 Qd4+ 21.Kh1 Qxe5 22.hxg4 hxg4 23.g3 Rd8 24.Kg2 Qf6 25.Nxf6+ Nxf6 26.Rh1+ Black resigned

Another Jerome Gambit Gemeinde member, Petasluk, had already handled the situation when Black supported the Bishop, rather than retreat or abandon it, in Petasluk - lowmiles, blitz, FICS, 2010: 8...d6 9.Nc3 c6 10.Ne2 g6 11.Qf3 Qh4+ 12.g3 Qh3 13.d4 Bb4 14.a3 Ba5 15.b4 Bb6 16.Bb2 Nf6 17.0-0-0 a5 18.d5+ cxd5 19.exd5+ Kf7 20.Bxf6 Kxf6 21.Qc3+ Kf7 22.Qxh8 axb4 23.axb4 Qg2 24.Nc3 Qf3 25.Qxh7+ Ke8 26.Rde1+ Kd8 27.Qe7 checkmate

Pawn-ful Lessons

A pawn advance seems to sew up the game for White, but it turns out upon further inspection that not as many were needed, only the proper amount of support from the pieces...

perrypawnpusher  - nmuffjgp
blitz FICS, 2010

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


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


This is one of the recognized refutations of the Jerome Gambit, but one reason I am pleased to face it is that White gets to eliminate Black's dark-squared Bishop which would otherwise hold up f2-f4.

7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Be6


10.0-0 Nf6 11.f4


An interesting alternative: 11.d3 Qd7 12.b3 Kf7 13.Bb2 Rhf8 14.Nd2 Kg8 15.f4 Ng4 16.Qg3 Bf7 17.h3 Nf6 18.f5 Ne5 19.Bxe5 dxe5 20.Qxe5 Rfe8 21.Qg3 Rad8 22.Nf3 Qc6 23.Rf2 Qc5 24.Raf1 a5 25.a4 b5 26.axb5 Qxb5 27.Kh1 c5 28.Ne5 a4 29.bxa4 Qxa4 30.Nxf7 Kxf7 31.Qc7+ Rd7 32.Qxc5 Kg8 33.e5 Nd5 34.f6 gxf6 35.exf6 Qa8 36.f7+ Kh8 37.f8Q+ Black resigned, fehim - BoardStupid, FICS, 2009.

12.d4


A dynamic alternative was 12.f5, as in 12...Bf7 13.d3 c6 14.h3 Qb6 15.g4 Qxe3+ 16.Bxe3 Kd7 17.Nd2 b6 18.Kg2 g6 19.g5 Nh5 20.f6 Nc8 21.d4 b5 22.b3 Nb6 23.Rac1 a5 24.c4 bxc4 25.Nxc4 Rhb8 26.Kf3 Nxc4 27.bxc4 Rb2 28.Rf2 Rab8 29.d5 c5 30.Rcc2 Rxc2 31.Rxc2 a4 32.Rc3 Kc7 33.Ra3 Be8 34.e5 dxe5 35.Bxc5 Rb2 36.Ke4 Re2+ 37.Be3 Bd7 38.f7 Black resigned, mrjoker - Melbourne, ICC, 2008.

12...d5 13.e5

Falling in with Black's plan. After the game Rybka suggested that White give up a Rook and a pawn for a couple of pieces: 13.f5 Bd7 14.e5 Nxf5 15.Rxf5 Ng4 16.Qf4 Bxf5 17.Qxf5 when Black has a small edge. 

13...Ne4


14.Nd2 Nxd2 15.Bxd2 Nc6


This move lets White's pawns run free. Instead, 15...Qd7 covers the f5 square.

16.f5 Bf7 17.e6 Bh5


18.h3

Preparing for the advance of more pawns. After the game Rybka showed that this was unnecessary. Instead, 18.Qh3 was strong, and after 18...Be2 White could afford 19.Rae1!? as 19...Bxf1 would be well met by 20.Qh5+.

Indeed, no further pawns need advance, if White's pieces are active.

18...Kf8

Better 18...Qf6 to answer 19.g4 with 19...Qxd4 although the Bishop is still lost after 20.gxh5.

19.g4

Here 19.f6 gxf6 20.Qh6+ Kg8 21.Qxh5 is stronger. 

19...Be8 20.g5


Again, this works, but stronger was 20.f6 gxf6 21.Qh6+

20...Ne7 21.f6


Here, 21.Bb4 would have tightened the screws before the pawn advance.

Black's resistance crumbles.

21...Ng6 22.e7+ Qxe7 Black resigned

More Than Meets the Eye

One of the joys of chess, and this has to be true even for that reprobate of openings, the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) and its relatives, is that often things on the board are not as they first appear to be: there is more than meets the eye. 

perrypawnpusher - udofink
blitz FICS, 2010

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


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


This is a solid response for Black – computers will rate the second player about 1 1/4 pawns better.

Familiarity has its benefits, however: my score with White against this position in 36 games is 93%.

7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3


9...Be6

This move is not as bad as I thought it to be, and my response is not as good as I thought, either.

10.f4

Black's response should cure me of this premature move.

I was more on target in an earlier game with 10.0-0 Nf6 11.f4 Kd7 12.f5 Bxf5 13.exf5 Re8 14.Qg5 Ne7 15.Qxg7 c6 16.Qxf6 Black resigned, perrypawnpusher - dirceu, blitz FICS, 2010

10...Qh4+


Thematic, and an improvement over 10...N6e7 11.0-0 Nc6 (11...Nf6 12.f5 Bf7 13.d3 c6 14.h3 Qb6 15.g4 Qxe3+ 16.Bxe3 Kd7 17.Nd2 b6 18.Kg2 g6 19.g5 Nh5 20.f6 Nc8 21.d4 b5 22.b3 Nb6 23.Rac1 a5 24.c4 bxc4 25.Nxc4 Rhb8 26.Kf3 Nxc4 27.bxc4 Rb2 28.Rf2 Rab8 29.d5 c5 30.Rcc2 Rxc2 31.Rxc2 a4 32.Rc3 Kc7 33.Ra3 Be8 34.e5 dxe5 35.Bxc5 Rb2 36.Ke4 Re2+ 37.Be3 Bd7 38.f7 1-0, mrjoker - Melbourne, ICC 2 12 blitz, 2008,) 12.d4 Bf7 13.Nc3 Qd7 14.e5 dxe5 15.dxe5 Qe6 16.f5 Qxe5 17.Qxe5+ Nxe5 18.Re1 Rd8 19.Bf4 Kd7 20.Bxe5 Nf6 21.Bxf6 gxf6 22.Ne4 Kc8 23.Nxf6 Rd6 24.Ne4 Rdd8 25.Rad1 Rxd1 26.Rxd1 Re8 27.Nc3 Bc4 28.Kf2 Rf8 29.g4 c6 30.b3 Bf7 31.Ne4 Bd5 32.Nc5 Rf6 33.c4 Black forfeited on time, perrypawnpusher - GabrielChime, blitz FICS, 2010

11.g3 Qg4


Here Black's followup is inaccurate, however. Certainly the Queen can be more annoying at h3.

After 11...Qh3, White might as well continue developing with 12.Nc3, as the pawn fork 12.f5, instead, would win a piece after 12...Bxf5 13.exf5+  but allow after 13...Kf8 the deadly move ...Rae8.  

12.f5

Now the pawn fork works, however.

12...Bf7

A bit better, but still leading to an edge for White, was 12...Nf6, which is best answered by 13.d3.

The problem now with 12...Bxf5 for Black is that after 13.exf5+ Kd7 (threatening ...Rae8, as in the not to White's 12th move) White can safely castle out of the threatened pin of his Queen. 

With a Black Queen on h3, that would not have been possible.

13.fxg6 Bxg6 14.d3 Kd7 15.0-0 Nf6 16.Nc3 c6


White is a pawn up.

17.Qf4

An exchange of Queens would make my King safer: Black has 4 pieces on the Kingside (with another Rook waiting in the wings) to my 2 pieces.

17...Qe6 18.Bd2 Rhf8 19.Qg5 Rf7 20.Rae1 Raf8


21.e5 dxe5 22.Qxe5


22...Qh3

Black declines to exchange Queens (his best choice), seeing his chances for an attack on the enemy King (starting with pressure on f1) to be good.

23.Bf4


It is Black's King, on the Queenside, however, who is at greater risk. 

23...Ne8

Not so good, but Rybka's suggestion after the game – to exchange Queens and give up a piece – is not attractive, either: 23...Qxh2+ 24.Kxh2 Ng4+ 25.Kg2 Nxe5 26.Rxe5.





analysis diagram





24.Qd4+ Kc8 25.Qxa7


26...Nd6 26.Qa8+

Noticing that capturing Black's Knight now leads to me being checkmated, I was a bit too nervous to work out the cool Knight sacrifice at b5, but after the game Rybka did: 26.Nb5 cxb5 (26...Nxb5 27.Qb8+ Kd7 28.Qxb7+ Kd8 29.Bg5+ Rf6 30.Qxg7) 27.Qc5+ Kd8 28.Qxd6+.

26...Kd7 27.Qa3


27...Nc8

White's Bishop is making things too hot, and Black needed instead to sacrifice the exchange with 27...Rxf4 in order to stay in the game.


28.Qc5 b6


Swatting at my Queen as if she were a bothersome mosquito, Black hastens his end.

29.Qd4+ Black resigned


Checkmate is unavoidable.

Timing

It is a bit of tricky timing, but sometimes right after I analyze and post a Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game I soon run into that particular line of play.

perrypawnpusher - GabrielChime
blitz 12 0, FICS, 2010

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


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


My opponent and I have played a few Jeromes. An earlier one continued: 6...Ke6 7.Qf5+ Kd6 8.f4 Ng6 9.Qd5+ Ke7 10.Qxc5+ d6 11.Qe3 Bd7 12.0-0 Qf8 13.e5 Kd8 14.exd6 Qxd6 15.Nc3 Nf6 16.d3 Re8 17.Qf2 Rf8 18.Be3 b6 19.Rae1 Nd5 20.Nxd5 Qxd5 21.Bd2 Qxa2 22.Bc3 Qd5 23.Bxg7 Re8 24.Rxe8+ Kxe8 25.f5 Ne7 26.f6 Ng6 27.f7+ Kd8 28.f8Q+ Nxf8 29.Qxf8+ Black resigned,  perrypawnpusher - GabrielChime, blitz FICS, 2009.

7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Be6

Earlier I had faced 9...Ne5 10.f4 Ng4 11.Qg3 g6 12.d4 Qe7 13.Nc3 Bd7 14.0-0 N4f6 15.e5 Nh5 16.Qf2 Bf5 17.exd6 Qxd6 18.Be3 Kd7 19.Rae1 Rd8 20.h3 Ngf6 21.g4 Black resigned, perrypawnpusher - GabrielChime, blitz FICS, 2009.

10.f4

Previously, I had castled, which is a better idea: 10.0-0 Nf6 11.f4 Kd7 12.f5 Bxf5 13.exf5 Re8 14.Qg5 Ne7 15.Qxg7 c6 16.Qxf6 Black resigned, perrypawnpusher - dirceu, blitz FICS, 2010

After the game Rybka preferred 10.Nc3, suggesting that after 10...Qh4 11.0-0 Nf6 12.f4 Bd7 13.f5 Ne7 14.d3 Kf7 Black had an edge.

10...N6e7


This move is okay, but as the previous note hints at, Black could have made more mischief with 10...Qh4+, e.g. 11.g3 Qh3 12.Nc3 Bg4 and White will find it difficult to castle.

11.0-0 Nc6


The game is roughly even.

An alternative was seen in mrjoker - Melbourne, ICC 2 12 blitz, 2008: 11...Nf6 12.f5 Bf7 13.d3 c6 14.h3 Qb6 15.g4 Qxe3+ 16.Bxe3 Kd7 17.Nd2 b6 18.Kg2 g6 19.g5 Nh5 20.f6 Nc8 21.d4 b5 22.b3 Nb6 23.Rac1 a5 24.c4 bxc4 25.Nxc4 Rhb8 26.Kf3 Nxc4 27.bxc4 Rb2 28.Rf2 Rab8 29.d5 c5 30.Rcc2 Rxc2 31.Rxc2 a4 32.Rc3 Kc7 33.Ra3 Be8 34.e5 dxe5 35.Bxc5 Rb2 36.Ke4 Re2+ 37.Be3 Bd7 38.f7 Black resigned 

12.d4 Bf7 13.Nc3 Qd7


14.e5

Probably advancing the wrong pawn. With a little patience, White would do well with 14.d5 Nce7 15.Qg3 Kf8 16.Be3 Nf6 17.Bd4 – although the position would still be level.




analysis diagram







14...dxe5 15.dxe5 Qe6


My opponent has grasped the weakness of  my pawn advance: the "Jerome pawns" can be frozen and blockaded, making the extra Black piece more valuable. Placing the Queen at f5 was necessary, however. 

16.f5

16...Qxe5 17.Qxe5+ Nxe5 18.Re1 Rd8


19.Bf4 Kd7 20.Bxe5 Nf6


White is a pawn up, but as I learned not long ago in my game against KaZC, that may not be enough for me to win.

21.Bxf6 gxf6 22.Ne4 Kc8


Black did not want to protect the f-pawn by moving his King to e7 and into the line of a possible discovered check. Yet the checks would prove harmless, while giving White a second pawn increases the first player's opportunities.

In all fairness, GabrielChime's time was getting short.

23.Nxf6 Rd6 24.Ne4 Rdd8 25.Rad1 Rxd1 26.Rxd1 Re8 27.Nc3


There is nothing really exciting going on: White plans to grind out the win.

27...Bc4 28.Kf2 Rf8 29.g4 c6


30.b3 Bf7 31.Ne4 Bd5 32.Nc5 Rf6 33.c4


Here, my opponent's flag fell.
