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: 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.)

Be Careful What You Read


It was pleasant to have my opponent choose the defense that he did, as it leaves White with a pawn plus advantage, even if attacking prospects have diminished. (Alas, because I believed that previous statement, I eventually got careless in my "zombie walk" and drew the game, as you will see.)




perrypawnpusher - HelloGoodby
blitz, FICS, 2012


1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


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




This defense does not have a name, but it might as well be called "the thinking player's defense," as it usually is composed by Black on the fly, to force the exchange of Queens and stifle White's attack. It is all very logical, although Black does exchange a won position for one that has him a pawn down...


8.Kxf2 Qf6+ 9.Qxf6+ Nxf6 10.Nc3 


Or 10.d3 as in perrypawnpusher - ScudRocket, blitz, FICS, 2009 (1-0, 24) 


10...d6 


I have also played 10...Re8 as in perrypawnpusher - BEEB, blitz, FICS, 2011 (½-½, 63) and perrypawnpusher - Conspicuous, blitz, FICS, 2011 (1-0, 22); and 10...Rf8 as in perrypawnpusher - Edvardinho, blitz, FICS, 2010 (1-0, 42). 


11.Rf1 


Alternatives include 11.d4 from perrypawnpusher - Mences, blitz, FICS, 2011 (1-0, 48) and 11.d3 from AlonzoJerome - adroit, ICC, 2011 (1-0, 25). 


11...Kg7 12.Kg1 Re8 


With aggressive intentions, but I have to think that the more modest 12...Rf8 would have been better. 


13.d3 a6 14.Bg5 Rf8 15.Bxf6+ Rxf6 16.Rxf6 Kxf6 17.Nd5+ 


Leading to the gain of a secone pawn. Black's better King position and Bishop do not compensate.


17...Ke5 18.Nxc7 Rb8 19.Rf1 Bg4 20.Nd5 


After the game Rybka preferred more aggressive play: 20.Rf7 d5 (20...Bd1 21.Kf2 Bxc2 22.Ke3) 21.Nxd5 Be6 22.Rxh7 Bxd5 23.exd5 Kxd5. 


20...Rc8 21.Rc1 


Making routine, not-thought-out moves, instead of 21.c3 Be2 (21...Bd7 22.d4+ Kxe4 23.Nf6+; or 21...Be6 22.d4+ Kxe4 23.Ne7 Re8 24.Re1+) 22.Rf7 Bxd3 23.Re7


To checkmate a King, you first have to realize that it might be possible, and then look for the right lines.


21...Be6 22.Ne3 


Thoughtless. Why not 22.Nc3


22...Bxa2 


Losing this pawn is not the end of the world for White, but it almost looks like the beginning of the end, and White's thinking has collapsed.


23.b3 Bxb3 24.Rb1 Bxc2 


Too greedy. Rybka suggested: 24...Kd4 25.Rxb3 Kxe3 26.Rxb7 Rxc2 27.h4 Kxd3 28.Rxh7 Kxe4.


25.Nxc2 


Overlooking the opportunity of 25.Rc1.


25...Rxc2 26.Rxb7 h6 


I have managed to squander my two pawn advantage, and Black might well be better here. Time to use the active Rook to get the draw.


27.Ra7 Ra2 28.Rh7 h5 29.Rg7 Kf6 30.Rd7 Ke6 31.Rg7 Kf6 32.Rd7 Ke6 33.Rg7 Kf6 34.Rd7 Ke6 Game drawn by repetition 

I suppose that both of us felt lucky with the outcome.

Trying My Hand at ICC (Part 3)


My last game at ICC ended, not with a bang, but with a whimper... by my opponent. We played a line where "Nothing Happened", which shows up in The Database 60 times, and in which Black scores 31% .

AlonzoJerome - adroit
blitz 5 5, ICC, 2011

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


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


6...g6 7.Qxe5 Bxf2+

Giving back the piece to break the attack, but going into a pawn-down Queenless middle game.

8.Kxf2 Qf6+ 9.Qxf6+ Nxf6 10.Nc3 d6


Black's best "chance" now is that I'll let him escape into a drawn Bishops-of-opposite-colors endgame, like I allowed BEEB.

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 Ng6


Nothing "exciting" has happened since the last diagram: I have grabbed some space in the center and my opponent has advanced on the Kingside. I can afford to play "deliberately" as long as I don't overlook the details. A pawn is a pawn, after all.

20.Bd2 g4 21.hxg4 Bxg4+ 22.Kd3 Rhf8 23.Nd5

More exact was 23.Nb5, with the same threat to the pawn at c7, but prohibiting ...c7-c6.

23...c6 24.Ne3

A little more could have been squeezed out of the position with 24.Nf4.

24...Bd7

Time was getting short for my opponent, but I am sure that neither of us saw the line recommended by Rybka 3, which keeps a tiny edge for White: 24...Nf4+ 25.Kc3 Ne2+ 26.Kb4 a5+ 27.Kb3 Bd7 28.Rxf8 Rxf8 29.Bxa5 Re8 30.Re1 Nxd4+ 31.Kc4 c5 32.Bc3 Kg6 33.Bxd4 Rxe4 34.c3 cxd4 35.cxd4 Bc6 36.b3 b5+.

25.Nf5+

More "business as usual," attacking the pawn at e6 and "suggesting" that Black exchange his Bishop for my Knight. Any kind of a win would be a long way off, as it would be after the stronger 25.Bb4.

Black resigned.

Perhaps he believed that I could continue to grind him down.
