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.

"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.)

[To be continued]

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.

Tap-Dancing on Ice

My latest Jerome Gambit was a slippery affair, a lot like tap-dancing on ice, for both me and my opponent. We each had our share of falls on the way to an interesting endgame. Finally, we reached the following position.



perrypawnpusher -BEEB
blitz, FICS, 2011

Despite White's outside, connected passed pawns, the best he can hope for is a complicated Queen-plus-pawns-versus-Queen-plus-pawns-ending which is most likely a draw at blitz speed, because soon (after ...Qxa2) Black will have his own connected passed pawns to run down the board. There will be too many chances to check the opposing King almost endlessly. The ticking clock will dictate safety.

35. Qf5+

This move does no harm, but as long as Black's King retreats to b6 it doesn't do much good, either.

Here is how the game could have continued, instead: 35.h4 Qxa2 36.Kh2 a5 (the race is on!) 37.h5 Qb2 38.Qg5+ (necessary to allow the White Queen to catch up with the h-pawn, otherwise, if 38.h6 then Black can rein in the runner: 38...Qe5+ 39.Qg3 Qh5+ 40.Qh3 Qe5+ 41.g3 a4 42.h7 Qh8 43.e5 a3 44.Qd7+ Kb6 45.exd6 a2 46.Qxc7+ Ka6 47.Qc4+ Kb6 48.Qxa2 Qxh7+ 49.Kg2 Qxd3 and a win, if there is one, is still a long way off) 38...Kc6 39.Qxa5 b5 40.d4 Kb7 (40...Qxd4 41.Qa6+ Kd7 42.Qxb5+ Ke7 43.Qg5+ and the White Queen is back on escort duty, although it is still complex) 41.h6 Qe2 42.Qc3 Qh5+ 43.Qh3 Qxh3+ 44.gxh3 b4 45.e5 (45.h7 b3 46.h8=Q b2 47.Qh7 b1=Q starting over again) 45...b3 46.e6 b2 47.e7 b1=Q 48.e8=Q and maybe there is a win, maybe there isn't...

35...Qe5

Oh, no.

A time-slip.

In the transition from middle game to endgame I had been checking Black's King, and perhaps my opponent figured that I would continue to do so, harmlessly, e.g. 36.Qd7+ Kb6.

But there is something better, and it can be seen, it doesn't have to be calculated.

36.Qxe5+ dxe5 37.h4 Kc6

Unfortunately, the King cannot enter the "square of the pawn". (Draw a diagonal from the pawn to the 8th rank. Black, to move, must be able to get inside that square in order to catch the pawn. He is one tempo short.)

38.h5 Kd6 39.h6 Ke7 40.h7

Black resigned

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+.

analysis diagram







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.

It's just really that important

In a recent book review at Chessville that I wrote about GM Nigel Davies' 10 Great Ways to Get Better at Chess (Everyman Chess, 2010), I mentioned

For an alternate “great way” – or as an addition – Chapter Two suggests Study the Endgame. Again, Davies gives game examples from his students, but this should not be necessary to persuade readers of the truth of his suggestion: most club players unconsciously imitate the play of early chess-playing computers, memorizing opening moves, concentrating on tactics at the expense of long-term planning, and playing the endings like duffers…

Davies would have been justified in giving a Chapter Three (“Study the Endgame Some More”) and a Chapter Four (“Keep Studying the Endgame”) just to reinforce the topic. It’s just really that important.

I wish I had taken more of my own advice before playing the following game.

perrypawnpusher - BEEB
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+

A "calming variation", but still a side line to watch.

8.Kxf2 Qf6+

8...Qh4+ was played unsuccessfully in annicks - Ribosome, Dos Hermanas Internet, 2002, (1-0, 23).

9.Qxf6+ Nxf6

By returning the sacrificed piece, Black has moved play into a Queenless middlegame or early endgame where he is simply down a pawn.

He no longer faces the Bashi-Bazouk attack of the Jerome Gambit. However, he also no longer has an objectively won game.

Sometimes, chess is a strange game.

10.Nc3

I have also tried 10.d3, as in perrypawnpusher - ScudRocket, blitz, FICS, 2009 (1-0, 24)

10...Re8

Black could play 10...Rf8 as in blackburne03 - bobby-pisher, Internet Chess Club, 2003, (1-0, 23) or perrypawnpusher - Edvardinho, blitz, FICS, 2010 (1-0,42); or in a delayed manner such as 10...b6 11.d3 d6 12.Rf1 Rf8 in blackburne - Bullit52, ChessWorld thematic tournament, 2007 (1-0, 32),


He also could start with 10...d6 and after 11.d4 c6 12.h3 play 12...Re8 as in brianwall - maten8, Internet Chess Club, 2004 (1-0, 21).

11.d3 d6 12.Rf1 Ng4+ 13.Kg1+ Kg7

Tactics can hide even in "boring" positions. For example, now 14.Nd5

14.h3

Laziness on my part. "The game will play itself."

The possible Knight fork at c7 remains "on" for a number of moves, despite my overlooking it.

14...Ne5 15.Be3 Be6 16.b3 c5 17.a4 a6 18.Rf2 Rf8 19.Raf1 Rxf2 20.Rxf2 Rb8 21.d4 Nd7 22.dxc5 dxc5 23.Nd5 b5

Like two zombies dancing a waltz, my opponent and I push the pieces around the board and pretend that we are playing chess...

24.axb5

If someone had whispered "Pssst. This is a middlegame" I might have looked for and found the tactical 24.Bf4 Rb7 25.Nc7 Bf7 26.Rd2 Nf6 27.Nxa6 bxa4 28.Nxc5 Rb5 29.Nxa4 Nxe4 30.Re2

analysis diagram







24...axb5 25.Nf4 Bg8 26.Nd3 c4 27.bxc4 bxc4 28.Bd4+ Kh6 29.Ne5 Rb1+ 30.Rf1 Rxf1+ 31.Kxf1 Nf6

For all of my shuffling, the e-pawn will now be lost.

32.Be3+ Kh5

My opponent has grown complacent, too, or he would have played the wiser 32...Kg7

33.c3

Readers who enjoy tactical endgames surely saw the better 33.g4+  which merely threatens checkmate after 33...Kh4 34.Kg2, costing Black his Knight.

Playing on "auto-pilot" was hurting both of us.

33...Nxe4 34.Bd4

The checkmate was still on, in a slightly longer version, with 34.g4+.

34...Ng3+ 35.Kf2 Nf5

This slip costs a piece.

36.g4+ Kh4 37.gxf5 gxf5 38.Kg2

With a piece for a pawn, White is now winning – but how exactly does he win?

If he can get his King to d4 and then attack the Black pawn at c4 a second time (with the Knight) he can win it. For that to happen, it might be best to trade White's weak h-pawn for Black's f-pawn. Then, with the help of the extra piece, White's c-pawn can be "faster" than Black's h-pawn.

38...Bd5+ 39.Kh2

Protecting the pawn for now. After the game Rybka suggested 39.Nf3+, since 39...Kh5 40.Kg3 Be4 41.h4 Bd5 42.Kf4 Be6 43.Bf2 Kg6 44.Ne5+ Kh5 45.Nc6 Bd7 46.Ne7 would allow White to win the f-pawn. If Black exchanges off the Knight instead with 39...Bxf3+ 40.Kxf3 then after 40...Kxh3 41.Kf4 White's King will wander over and win the Black c-pawn and Queen his own; the Black h-pawn will not be an issue.

39...Be6 40.Nf3+ Kh5 41.Kg3 f4+

A mistaken offer to exchange pawns that I should have accepted.

42.Kh2 Kg6 43.Kg2 Kf5 44.Ne5 Bd5+ 45.Nf3 Bg8

Black is content to sit and wait.

It is not clear to me that there is a win any more for White, as Black's advanced King and h-pawn make it dangerous for White's King to leave that area to help win the c-pawn.

My "winning try" falls to the inevitability of the Bishops-of-opposite-colors endgame.

46.Kf2 Ke4 47.Nd2+ Kd3 48.Nxc4 Kxc4 49.Kf3 Be6 50.h4 Kd5 51.Kxf4

The position is drawn now, and a dozen moves later, too.

51...Bf7 52.Kg5 Bg6 53.h5 Bd3 54.Kf6 Ke4 55.Kg7 Kf4 56.h6 Kg5 57.Bf6+ Kh5 58.Bd4 Kg5 59.Be3+ Kh5 60.c4 Bxc4 61.Kxh7 Bd3+ 62.Kg7 Kg4 63.h7 Bxh7 drawn

This game contained plenty of wasted opportunities.
