Jerome Gambit Ending: It's Drawn, Unless It Isn't (Part 1)

                                                                     

I won my last Jerome Gambit in the current Chess.com Giuoco Piano Thematic Tournament, so it is time, again, for me to sit and wait and see who catches or bypasses me.

In the meantime, it is fun to share the game, as it required some strategic re-thinking on my part, as well as a pleasant return to some endgame understanding that I acquired about 35 years ago, from a match game I played against my boss.

perrypawnpusher - keshavdmutkule
Giuoco Piano Thematic Tournament,  Chess.com, 2016

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



The Giuoco Piano Thematic Tournament is a 10-player, double round robin, which means that I had 9 chances to play the Jerome Gambit - and, as it turned out, I played 8 at the same time to start the tournament! (I had Black against keshavdmutkule first.) I finished with 4 wins, 3 wins on time, and 2 losses.

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8



Ah, yes, the Jerome Defense to the Jerome Gambit - both care of Alonzo Wheeler Jerome. The defense was played successfully in two correspondence games against Daniel Jaeger in 1880.

To date my record against it is 23-6-3, which is a score of 81%, which is pretty decent.

7.Qxe5 Qe7 

Solid. Black's Queen sometimes goes to f6 in different variations, but here it finds itself a different home. I have scored 6-2-2  (70%) against this.

7...d6 was seen in perrypawnpusher - ulisimbolon, Giuoco Piano Thematic Tournament, Chess.com, 2016, (0-1, 22). (keshavdmutkule would have had to look up that game on the Chess.com website, as it wasn't posted on this blog until recently.) 

8.Qf4+ Ke8

I faced 8...Nf6 in the earlier perrypawnpusher - ERICOLSON, FICS, 2007 (1-0, 33); perrypawnpusher - frencheng, 10 5 blitz, FICS, 2010 (1/2-1/2, 31); and perrypawnpusher - jonathankochems, FICS, 2010 (1-0, 39).

The text move strikes me as a bit unusual, and it highlights one of Black's challenges in the Jerome - even if he is still better - and that is: where does his King go?

Of equal interest to me was if my opponent had found this blog, and, more specifically, my notes to my game with auswebby.   

9.O-O

I am not sure if the text is an improvement over 9.Nc3, seen in perrypawnpusher - Chesssafety, Chess.com, 2012 (1-0, 25) and perrypawnpusher - auswebby, Giuoco Piano Thematic, Chess.com, 2015 (0-1, 37), but the games could have transposed, anyway.

9...d6

More sedate and more solid than 9...Bd6 as seen in perrypawnpusher - dzetto00, Giuoco Piano Thematic, Chess.com, 2016(1/2-1/2, 25). (Too bad. I was willing to face that line again.)

10.c3 Nf6 11.d4 Bb6 12.Re1 Kf7



Black plans to castle-by-hand on the Kingside.

13.Nd2

I am used to attacking the Black King along the e-file or f-file, or advancing the "Jerome pawns" to cause chaos in the enemy's ranks.

In this game, however, I realized that there was not likely to be any kind of bashi-bazouk attack; instead, I was going to have to adopt the patient style that I have seen in some of Bill Wall's games, where he establishes a solid pawn center and waits for his opponent to bash himself against it. After all, Black has the advantage, so, by rights, he should be the one attacking, right?

13...Re8 14.Nc4 Kg8 15.Nxb6 axb6 16.f3

Toward Disaster



As I have mentioned in an earlier post, I have joined a Chess.com 12-player "Giuoco Piano" tournament (3 groups of 4 players each).
I immediately got to start a couple of Jerome Gambits, so we'll see how they turn out.The first game is racing along the lines of a refutation that has many blog posts here, all saying that White is lost, White is lost...
Well, sad to say, White did lose - but part of the reason was my refusal to play a thematic "Jerome pawn" advance which would have helped keep the play dynamic. The second big mistake was to not be as familiar with Jerome Gambit history as I should be. Ouch.

perrypawnpusher - auswebby

Giuoco Piano Tournament, Chess.com, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 7.Qxe5 Qe7 8.Qf4+ Ke8



Instead, 8...Nf6 was seen in a couple of correspondence games between Daniel Jaeger (White) and Alonzo Wheeler Jerome  in 1880.


More reently, Bill Wall faced 8...Qf6 in a handful of games: Wall,B - GoldCoinCollector, Chess.com, 2010 (1-0, 17);  Wall,B - GuestZCLK, FICS, 2011 (1-0, 15); Wall,B - Guest340293, PlayChess.com 2012 (1-0, 41); Wall,B - Josti, PlayChess.com, 2013 (1-0, 26); and Wall,B - Guest4644930, PlayChess.com, 2014, (1-0, 26).


9.Nc3 Nf6 10.0-0 d6 


Or 10...Bd6 as in perrypawnpusher - Chesssafety, Chess.com 2012, (1-0, 25).


11.d3


White got away with the Knight jump 11.Nd5 in xcvbnm -SAHFAN, FICS, 2013 (1-0, 28), but I should have been more familiar with the game (in The Database) as Black was better most of the game; and White's win came only when his opponent blundered into a mate-in-2.


11...Be6 12.Be3 Bxe3 13.Qxe3 Kd7 14.f4 Rhf8 15.f5 Bg8 16.d4 Rae8 17.Rae1 Kc8 18.Qg3 




Instead, it was time for 18.e5. The text allows Black to take a step toward preventing that move, and my response (see the note to White's 11th move) sealed my doom.


18...Nd7 19.Nd5 Bxd5 20.exd5 Qf6 




I thought I had a few tricks against Black's King on the back rank, but, really, there was nothing.


21.Rxe8+ Rxe8 22.c3 Nb6 23.Re1 Qf7 24.f6 Rxe1+ 25.Qxe1 Qxf6 26.Qe8+ Qd8 27.Qf7 Qh8 28.b3 Nd7 29.c4 Kd8 30.Kf2 Qf8 31.Qxf8+ Nxf8 32.Kf3 Ke7 33.Ke4 Kf6 34.c5 Ng6 35.g3 b6 36.b4 Ne7 37.a3 b5 White resigned.
