Jerome Gambit: Reassessing a Variation (Part 2)




[continued]

As noted in the previous post, I just completed my 3rd Jerome Gambit game in the first round of the "Italian Battleground" tournament at Chess.com.

The challenge after a dozen moves in this game was to transition from a wild attack to a more measured, patient approach, and then match wits with an opponent who had reset the battlefield as an endgame.

12.Bg5 h6 13.Bxf6 Kxf6 14.Ke3 c6 



15.Rhf1+ Ke7 16.Rf2 Raf8 17.Raf1 Rxf2 18.Rxf2 Be6 



I had expected 18...Rf8 19.Rxf8 Kxf8 exchanging off the Rooks. Gaining control of the f-file isn't immediately helpful, but its value will grow.

19.Ne2 Bf7 20.b3 Re8 

Black wanted to be ready for when I played e4-e5. On the other hand, I was trying not to play the move too early. 

21.c4 g5 22.Nc3 Bg6 

23.d5 c5 

A committal move. I had planned to meet 23...cxd5 with 24.Nxd5+, infiltrating on the f-file. After the game, Stockfish 8 suggested the slow 23...a5 24.Kd4 h5 25.c5 dxc5+ 26.Kxc5 Kd7 27.Kd4 cxd5 28.exd5 Re1, and Black would continue to resist, although White would be better.

24.e5 

24...dxe5

Black preferred not to face 24...Kd7 25.e6+ Ke7, but that might have been better.

25.Ne4 

I was pleased with the clearance sacrifice, but, in all fairness, there were not a lot of ideas in the position, so I was bound to trip over it eventually.

25...b6 26.Rf6 

26...Bxe4 

Possibly hoping for 27.Kxe4? Kxf6, winning.

27.Re6+ Kf7 28.Rxe8 Kxe8 29.Kxe4 Black resigned



The pawn on e5 will fall, and then the ones on the Kingside.

Jerome Gambit: Reassessing a Variation (Part 1)


I just completed my 3rd Jerome Gambit game in the first round of the "Italian Battleground" tournament at Chess.com. The win, making me 2 - 0 - 1 with my favorite opening, so far, should be enough to earn me first place in my group, and allow me to eventually move on to the second round.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ 

Despite Alonzo Wheeler Jerome's early preference, and that of Bill Wall and others, I have only played 6.d4 once, and that game took a bit of a swindle for me to get a draw. To each one's own.

6...g6 

This move was not a surprise. The best known Jerome Gambit game, Amateur - Blackburne, London, 1884 (see "Nobody expects the Jerome Gambit!" and "Jerome Gambit: Dr. Harding Checks In") features this move, and if my opponent was likely to know anything about the opening, this would be it.

7.Qxe5 Bxf2+ 

A bit of a surprise - but not really.

Instead of offering a Rook with the Blackburne Defense, 7...d6!?, or preparing a wicked counterattack with Whistler's Defense, 7...Qe7!?, my opponent plays what I have elsewhere referred to as an "inoffensive defense" (see "An Inoffensive Defense") and a "calming defense" (see "Nothing Happened").

The Database has a surprising 1,375 games with this position, with White scoring 53%, which compares favorably with ther 46% produced by 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+. (Nine games are mine, with White scoring 89%).

In our first game in this tournament, we quickly moved to an endgame where I was a pawn up - but it took some fancy calculating to win the game. My opponent currently has fashioned a very interesting blockading position in one of his other games (he is a pawn down) and should soon split the point. So, to see our game move quickly to a Queenless middlegame, with the promise of an endgame, was understandable - zmarian likes endgames.

8.Kxf2

ZahariSokolov of FICS has played 8.Ke2?!, but I can't recommend the move: 8...d6? 9.Qxh8? Qf6? 10.Qxh7+Kf8 11.h3 b6 12.Rf1 Ba6+ 13.d3 Re8 14.Rxf2 Rxe4+ 15.Be3 Qxf2+ 16.Kxf2 Black resigned, ZahariSokolov - Posapiano, standard, FICS, 2015

8...Qf6+ 

Black did not improve things by playing 8...Qh4+ 9.g3 Qf6+ 10.Qxf6+ Nxf6 11.Nc3 Re8 12.d3 c6 13.Kg2 Kg7 14.Bg5 Ng4 15.h3 Nh6 16.Rhf1 d6 17.Rf2 Be6 18.Raf1 Rf8 19.Bxh6+ Black resigned, perrypawnpusher - Hensel, blitz, FICS, 2014.

9.Qxf6+ Nxf6 

The curious game perrypawnpusher - ronn, blitz, FICS, 2009, continued 9...Kxf6 Black resigned.

10.Nc3

I have played 10.d3 a couple of times, in perrypawnpusher - Edvardinho, blitz, FICS, 2010 (1-0, 42) and perrypawnpusher - Dubnobase, blitz, FICS, 2013 (1-0, 49).

10...d6 


Black has a number of replies. I have faced 10...Re8 a couple of times: perrypawnpusher - Conspicuous, blitz, FICS, 2011 (1-0, 22) and perrypawnpusher - BEEB, blitz, FICS, 2011 (1/2-1/2, 63).

(Oddly enough, I don't seem to have posted either of these games on this blog. I will have to remedy that.)

11.d4 

Playable is 11.d3, which I have tried a couple of times: AlonzoJerome - adroit, blitz, ICC, 2011 (1-0, 25) and perrypawnpusher - HelloGoodbye, blitz, FICS, 2012 (1/2-1/2, 34).

(You wouldn't have known it by this blog, though: two more games to find and post. What was going on in 2011 and 2012, I wonder.)

11...Bd7 

Interesting. Understandable was 11...Rf8, which I have also faced in perrypawnpusher - Mences, blitz, FICS, 2011 (1-0, 48).

(Also not posted here. Very odd. My "to do list" is growing.)
