"Jerome pawns" - Clowning Around


After my discouraging loss with the Jerome Gambit in my previous Chess.com Italian Game tournament (perrypawnpusher - Buddy_Thompson), I knew that I had to cook up something new, or risk facing a future opponent who just "looked the refutation up" (and not even on this blog, mind you, but in my recent games on Chess.com).

I was happy that I did do the research, too, because in my third Jerome Gambit in my current tourney, my opponent went straight for the same line (leaving out the superfluous Queen check).

As often happens, the white "Jerome pawns" held a starring, if comic, role in the game, supporting me while mistreating the Black King horribly.

perrypawnpusher - djdave28
Chess.com Italian game tournament, 2014

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.f4 Qf6 9.fxe5+ Qxe5 

10.Qxe5+

This was my idea, to "surrender" to Black's plan. Exchanging Queens isn't much worse than leaving them on. I found only 30 examples of this line in The Database, including a few played by "Blackburne", Louis Morin and UNPREDICTABLE.

If we go back to the perrypawnpusher - Buddy_Thompson, Chess.com, 2014 game, however, with 8...Qh4+ 9.g3 Qf6 thrown into the move order, there are two relevant precendents: NN - Kapil Gain, Internet, 2004 (1-0, 56) and perrypawnpusher - Kevin the Fruitbat, Jerome Gambit Thematic, ChessWorld.net, 2008.(1-0, 38). Both are discussed at "Jerome Gambit Tournament: Chapter XIII".

Likewise, if we use the opening approach 7.f4 (instead of 7.Qf5+) Qf6 8.Qxe5+ Qxe5 9.fxe5 Kxe5 we reach the same position as in the game, only a move earlier. There are 13 examples of this in The Database, but only one follows our main line (see below).

10...Kxe5 11.b4

This is the reason I went into the line - it looks hokey, and the next few moves by White don't suggest that I know what I am doing, either. (It's only showed up twice - three times if we count transpositions - before in The Database.)


I was pretty sure that I had discussed the line in an email with Stefan Bücker, editor of Kaissiber, years ago; but I have not been able to find our correspondence on the topic.


11...Bb6


The alternative, 11...Bd4, was seen in two games:


Spike1.2 - Fritz 6.0, USA 200612.c3 Bb6 13.d4+ Kxe4 14.Nd2+ Kf5 15.0-0+ Ke6 16.a4 a5 17.b5 Nf6 18.Ba3 Re8 19.Rae1+ Kf7 20.Rxe8 Kxe8 21.Re1+ Kf7 22.Nc4 Nd5 23.Rf1+ Ke6 24.Re1+ Kf6 25.Rf1+ Kg5 26.Bc1+ Kh4 27.Rf5 Nxc3 28.Be3 Bxd4 29.Bxd4 Ne2+ 30.Kf2 Nxd4 31.Rf4+ Kg5 32.Rxd4 b6 33.Ne3 Ra7 34.Rc4 Kf6 35.Nd5+ Ke5 36.Nxb6 cxb6 37.Rxc8 d5 38.Rh8 h6 39.Rb8 Rf7+ 40.Ke3 Rf6 41.h3 h5 42.Rh8 Rh6 43.Re8+ Re6 44.Rc8 Kd6+ 45.Kd3 h4 46.Rc2 Re4 47.Rc6+ Ke5 48.Rxb6 Rxa4 49.Ra6 Ra2 50.b6 Rxg2 51.Rxa5 Rb2 52.Ra6 g5 53.Kc3 Rb5 54.Kc2 g4 55.hxg4 Kf4 56.Ra4+ Kg5 57.Rd4 h3 58.Rd2 Rxb6 59.Rxd5+ Kh4 60.Rd2 Rf6 61.g5 Kxg5 62.Rd5+ Kg4 63.Rd1 h2 64.Kb3 Rf4 65.Ka2 Rf3 66.Rc1 Kh3 67.Rc8 Kg2 68.Rg8+ Rg3 69.Rh8 h1Q 70.Rxh1 Kxh1 71.Kb2 Kg2 72.Kc2 Kf1 73.Kd2 Rh3 74.Kc1 Ke2 75.Kc2 Rd3 White resigned;

12.Bb2+ Bd4


The "idea" behind the line appeared in axykk - bromby, FICS, 201112...Kxe4 13.Bxg7 Black resigned.


13.c3 Bb6 14.d4+ 


14...Kxe4


I wouldn't be surprised to find that taking the pawn isn't the strongest move (see Spike1.2 - Fritz 6.0, USA, 2006, above). It reminds me of the Blackburne Shilling Jerome Gambit line, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+ Kxf7 5.Nxe5+ Ke6 6.c3 Kxe5 7.cxd4+ where Black has to think "homeward bound" for his King, or risk dangerous play. More prudent in our game seems 14...Ke6.


I suspect that my opponent saw the position as an endgame, in which case his King should be safe; while I saw it as a Queenless middlegame, where I still had tactical intentions. 

15.0-0 Nf6 16.Nd2+ Kd3 17.Nf3 d6 18.Rad1+ Kc4 19.Nd2+ 




I was hoping for 19...Kd3, when I was going to plan 20.Nf3+ and offer a draw. I know that's a bold thing to do, down a piece, but I thought Black's King might be feeling homesick.


19...Kb5


Again, a surprise. I thought that after 19...Kd5 I could play 20.c4+ and 21.c5 and win the piece back - hoping that my lead in development would compensate for my lack of pawns.


20.a4+


Played automatically, remembering a comment that Bill Wall once made to me, that certain moves just have to be played, not even thought over. Here, it either works, or White is doomed, anyway - I'm a piece down, and if Black's King escapes, I got nothin'... 


To my chagrin, when this game was over and I shared it will Bill, he suggested 20.c4+ instead.


20...Kxa4 21.c4 


The "Jerome pawns" do special duty, hemming in the King.


21...Kxb4 


This move, however, leads to a pie in the face. After the game, both Bill and Houdini suggested 21...d5.


22.Rf3 Black resigned


The King cannot escape checkmate.

Update: 8...Qf6




Repeating the "comments" that follow a recent blog post (see "Slaughter"):




Guido De Bouver said...
     8...Qf6 seems like a killer black reply in the position you described ? [after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.f4]
     What has been tried here ?

Rick Kennedy said...
Guido,
     You are right, 8...Qf6 is strong for Black. It is at least as old as A.W. Jerome - W. Shinkman, USA, 1874 (0-1, 21).
     The Database is somewhat misleading in this regard, as it has 50 games with 8...Qf6, with White scoring 58%.
     After 9.fxe5+ Qxe5 The Database has 53 games (it picked up two games with 8...Qe7 and one with 8...Qe8) with White scoring 59%.
     White has tried 10.Qxe5+, 10.Qf8+, 10.Qg4, 10.Nc3, 10.c3 and 10.Qf3 with different degrees of success.
     10.Qf8+ scores worst (0%, 3 games) and 10.Qg4 scores best (100%, 1 game); with 10.Qf3 being the currently recommended move (71%, 27 games)
     This topic certainly deserves a post or two -- and soon! I will get to work on it.
     Thanks.

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


7.Qf5+ Kd6 8.f4 Qf6


9.fxe5+


The most recent coverage of the 8...Qf6 line in this blog was in the game axykk - bromby, blitz, FICS, 2011: 9.fxe5+ Qxe5 10.Qxe5+ Kxe5 11.b4 Bb6 12.Bb2+ Kxe4 13.Bxg7 Black resigned

9...Qxe5 10.Qf3

After 10.Qf3, Black has to avoid falling into the "Disdainful Defender Defense", for example, 10...Nf6 11.d3 Rf8 12.Bf4 and the Black Queen is lost. This is one of those apparent "optical illusions" that appear from time-to-time in the Jerome Gambit, and in this case it has accounted for 9 wins for White.

Instead, 10.Qf3 Nf6 22.d3, and as Jerome wrote of his last move in the April 1874 issue of the Dubuque Chess Journal, "Compelling either K or Q to move as White threatens Bf4; or Black can play ...g5" [translated to algebraic notation].

10...Nf6 11.d3 Kc6 12.c3


White has only one pawn for his sacrificed piece, and he is currently behind in developement. He works with what he has available, however: the central "Jerome pawns" and Black's misplaced King. Something will come up (see "Like the Big Boys").

Wait a minute... White resigned?

Yes, good Readers, it is true. Losses by Bill Wall in The Database are rarer than hens' teeth, but they occasionally happen. (Cherish this one; you will probably not see another.)

Every once in a while I have to point out that the Jerome Gambit is, "officially", a refuted opening no matter how many times we win with it!

Say, what...?


While playing against an opponent who has a sense of what is going on in the Jerome Gambit is one thing (see, for example, "La la la la la..."), playing against an opponent who seems to be bamboozled can be quite another, as axykk demonstrates...


axykk - bromby
blitz, FICS, 2011

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


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


When Black makes this move it usually means that either he is new to the Jerome Gambit, and wants to hang on to the second piece, or that he has studied the Jerome Gambit and this is the defensive system that he is most comfortable with.

The Database indicates that bromby faced and defeated a "modern" Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.d3) in 2006; and drew and won against Petasluk in 2009 in a couple of 5.Nxe5+ Nxe5 6.Qh5+ Ng6 games. So: not necessarily "new" to the Jerome Gambit, but is he prepared ?

7.Qf5+ Kd6 8.f4 Qf6


A solid defense, as we know from analysis dating back to Alonzo Wheeler Jerome and the April 1874 issue of the Dubuque Chess Journal. Over the years, Shinkman, Jaeger, Colburn and Charles beat the opening's "inventor" with it.

9.fxe5+ Qxe5 10.Qxe5+

This is a relatively new idea, as opposed to retreating the Queen to f3. The Database has games with this move by Louis Morin in each of 2001, 2002, and 2003, all wins.

I don't think that bromby was quite prepared for it.

10...Kxe5 11.b4

" 'Freedom' 's just another word for 'nothing left to lose' " as the song goes. Axykk can play freely with the White pieces, as he's already had a "lost" game since move 4. What is the worst thing that can happen now?

11...Bb6

Suspicious of White's motives, Black retreats.

It seems silly to point out that 11...Bd4 12.c3 Bb6 13.d4+ Kxe4 was better – not everyone wants to know what happens after 14.Nd2+ Kf5 15.0-0+, especially against a higher-rated player at blitz speed.

12.Bb2+ Kxe4

Befuddled. At a distance we can recommend the same notion as above, with 12...Bd4 13.c3 Bb6 14.d4+ and even after 14...Kxe4 Black will be better.

13.Bxg7

Black resigned

It might have been worth hanging around to try (wait for it...) 13...Bd4, as White would have to find 14.Nc3+ to keep his edge, i.e. 14...Bxc3 (nothing else comes close to working) 15.dxc3 Ne7 16.Bxh8 when White would be a solid exchange ahead, and his Kingside pawn majority would spell future trouble for Black.
