Jerome Gambit: Lost Games (Part 2)

Image result for free clip art discovery

As I discovered recently, a few of my older games that have escaped scrutiny on this blog, so I am sharing them.

The following game is as quiet as expected after Black's 7th and 8th moves.

AlonzoJerome - adroit
5 5 blitz, ICC, 2011

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 Bxf2+ 



The line we have been examining
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").

8.Kxf2 Qf6+ 9.Qxf6+ Nxf6 10.Nc3 d6 



11.d3 Bd7 12.Bg5 Ng4+ 13.Ke2 h6 14.Rhf1+ Kg7 15.Bf4 g5 16.Bg3 h5 17.h3 h4 18.Be1 Ne5 



19.d4 

Tempting. Perhaps 19.Nd5 c6 20.Ne3 Rhf8 21.Bc3 was better. 

19...Ng6 20.Bd2 g4 21.hxg4 Bxg4+ 22.Kd3 Rhf8


23.Nd5 

After the game Stockfish 8 recommended 23.Nb5, to be met by 23...Bd7 24.c4 (Not 24.Nxc7 Rxf1 25.Rxf1 Rc8 and the Knight can't withdraw because of  26...Bb5+) 24...Bxb5 25.cxb5 with an advantage to White. 

23...c6 24.Ne3 Bd7 25.Nf5+ Black resigned



The pawn at d6 will fall, and being down two is enough for my opponent.

Jerome Gambit: Lost Games (Part 1)


Recently, I discovered a few of my older games that have escaped being posted on this blog, so I am sharing them - it just seems fair to those who also risk the Jerome.

The following game has some of my typical tactical oversights (perhaps this is why the game got "lost"), ending when my opponent decided the future was not very bright for him. 

perrypawnpusher - Conspicuous
blitz, FICS, 2011

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 Bxf2+ 



This is the line we have been looking at. There is a bit of psychology in the counter-sacrifice.

8.Kxf2 Qf6+ 9.Qxf6+ Nxf6 10.Nc3 Re8 



As noted before, better is 10...d5 11.exd5 Rd8

11.d3 c6 12.Rf1 Kg7 13.Kg1 Rf8 14.Bg5 Nh5


Kicking the Bishop with 14...h6 was better. 

15.Rxf8 

I decided on the exchange-Rooks-and-then-check-with-a-Rook tactic, when I should have seen 15.Bh6+! Kxh6 16. Rxf8 winning the exchange.

15...Kxf8 16.Rf1+ Kg7 17.g4 h6 



18.Bh4 

Planning on exchanging pieces and breaking up the pawns on Black's Kingside. Instead, 18.Be3! would simply win the Knight, e.g. 18...Nf6 19.Bd4 etc.

18...g5 19.gxh5 gxh4 20.Rf4 h3 



Black would have done better to ignore the pawn and focus on development, 20...d6 21.Rxh4 Be6.

21.Rg4+ Kf6 22.Rg6+ Black resigned



The pawn on h6 is a goner, and the one on h3 may soon follow. My opponent apprently had better things to do with his time than to wait for the inevitible advance of my h pawns.

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.


perrypawnpusher - zmarian
"Italian Battleground" tournament, Chess.com, 2018



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.


perrypawnpusher - zmarian
"Italian Battleground" tournament, Chess.com, 2018

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.)

Jerome Gambit: Dangerously Messy

When facing a surprise or unusual attack - such as the Jerome Gambit - one defensive strategy is to turn the game into a "mess", and hope for the best. In the following game, Black tries this, and things become so mixed up that he has greater chances than if he had stayed along "peaceful" lines - but, eventually the game becomes less "dangerously messy" and White triumphs.

Wall, Bill -Guest3440
chesstempo.com, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bb4+ 


A clever alternative to 6...Bxd4.

7.c3 Bxc3+

Black also had the bold alternative 7...Qh4!?

8.Nxc3 Nc4 

Black probably wanted to avoid the kick-the-Knight variation 8...Nc6 9.d5 Ne5 10.f4 Ng6 but should have opted for 8...Ng6 directly.

9.Qh5+ Kf8 

Or 9...g6 10.Qd5+ Kf8 11.Qxc4 Ne7 12.Bh6+ Ke8 13.Nb5 c6 14.Nd6 checkmate, Wall,B - Minaevm, lichess.org, 2017

10.Qc5+ Nd6 11.e5 b6 12.Qa3 Qe8 


Black struggles with his pinned Knight. He probably should have surrendered it with 12...c5 13.exd6 Qe8+ 14.Ne2 Bb7 15.dxc5 Nf6 16.Be3 Bxg2 17.Rg1 Be4 18.O-O-O bxc5 and a very messy position. 

13.Nb5 Qg6

This does not work.

14.Qf3+ Nf5 15.Qxa8 Nge7 16.Nxa7 Kf7 17.Qf3 Kg8 


The position is a mess, but one that favors White, who is an exchange and a couple of pawns ahead.

18.Nxc8 Nxc8 19.Qd5+ Qe6 20.Qxe6+ dxe6 21.Be3 Black resigned

Things have settled down, which means Black's chances have been reduced.

Jerome Gambit: White's Game Is In Its Last Throes (Again)

Image result for free clip art dying

According to the hypermodern player Gyula Breyer, after 1.e4 White's game is in its last throes.

Subsequently, many played 1.e4, and lost.

Of course, many played 1.e4, and won.

Chess is complicated like that. Even after you play the right, best move - you have to play another one, and another one, and then another one...

In the following Jerome Gambit game, Black plays a very promising 6th move, but his opponent does not oblige him by resigning. Instead, the game goes on, and before 20 more moves are played, it is Black who has to turn over his King. 

Wall, Bill - Mecnieri
PlayChess.com, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



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



The Database has 250 of Bill's games with this position. (White scored 91%.)

6...Qh4

Possibly Black's strongest reply - but only played against Bill 30 times. (White scored 85%.)

7.O-O Ng4 8.h3 Bd6 

The position looks scary for White.

9.e5 Nxe5 

"Scientifically" returning one of the sacrificed pieces for a couple of pawns. Bill pointed out the alternative 9...Be7 10.hxg4 d6 and Black is still better.

10.dxe5 Bxe5 11.Qd5+ 



11...Kf8 

Black returns the second sacrificed piece, but could well have played 11...Kf6 12.Re1 Bd4

12.Qxe5 d6 13.Qa5 Qe7



Material equality has been reestablished. White's King is safer, however. It is also good to remember the curious Jerome Gambit bromide: when White has equalized, he has the advantage. 


14.Nc3 Nf6 15.Nb5 c6 16.Nd4 h6 



Black moves to keep White's Bishop off of g5, but he doesn't have time for this.

17.Re1 b6 18.Qc3 Nd5 


A tactical slip. He would have done better with 18...Qd7

Now White puts on the pressure and wraps up the game.

19.Nxc6 Nxc3 20.Nxe7 Bb7 21.Ng6+ Kg8 22.Nxh8 Kxh8 23.bxc3 Black resigned


Everything looks pretty well balanced - until you notice that White is up a Rook.
