Reliable

It had been months since I had played the Jerome Gambit at blitz speed, and I worried that I might have forgotten too much. The following game, however, shows that the opening was as reliable as ever for me.

perrypawnpusher - grosshirn
2 19 blitz, FICS, 2016

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.f4 Ng6

Somewhat inexact. See the note (below) to White's 11th move.

9.Qd5+ Ke7 10. Qxc5+ d6 

Better than 10...Ke8 as seen in perrypawnpusher - parlance, blitz, FICS, 2011 (0-1, 22). 

11.Qe3

After 11 moves we have reached a position in which White has an extra move (f2-f4) in comparison to the line 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Ke7 8.Qxc5+ d6 9.Qe3. So, if Black wants to give up his King's Bishop and post his Knight at g6, 6...Ng6 might have been a better choice.

Interestingly, Stockfish 7 recommends the alternate retreat 11.Qc3 (no example in The Database), suggesting that Black meet that with 11...Kf8 (11...Nxf4?12.Qxg7+ Ke8 13.O-O Qf6 14.Qxf6 Ne2+ 15.Kf2 Nxf6 16.Kxe2 Nxe4 with advantage to White) 12.O-O Nf6 13.f5 Ne5 14.d4 Nc6 15.e5 dxe5 16.dxe5 Qd4+ 17.Qxd4 Nxd4 18.Na3 Ne8) with an equal game.

11...Nf6

The text is about equal to 11...Kf8 (perrypawnpusher - Valseg, blitz, FICS, 2011 [1-0, 39]), better than 11...Bd7 (perrypawnpusher - GabrielChime, blitz, FICS, 2009 [1-0, 29]), and much better than 11...Be6 (perrypawnpusher - MrNatewood, blitz, FICS, 2010 [1-0, 12]).

12.O-O

Or 12.d4 as in perrypawnpusher - thinan, blitz, FICS, 2010 (1-0, 31).

12...Rf8

This seems reasonable at first glance, as Black is considering castling-by-hand. However, 12...Re8 was probably better, as in perrypawnpusher - spydersweb, blitz, FICS, 2012 (1-0, 24) and perrypawnpusher - tjaksi, blitz, FICS, 2014 (1-0, 18). 

13.f5 Ne5 14.d4 Nc4 15.Qd3 Nb6 16.Bg5 h6 17.Bh4 Nbd7

Black has covered up with his pieces, and still has his piece-for-two-pawns material advantage, but White's "Jerome pawns" and freer development give him the advantage.

18.Nc3 c6 19.Rae1 Qb6 20.Kh1 Ke8

Breaking the pin on his Knight, but White is ready to crash through, anyhow. 

21.e5 dxe5 22.dxe5 Ng8 23.f6

Even better, according to Stockfish 7 after the game, was 23.Ne4 Ne7 24.Qd6 Rf7 25.e6 with a forced checkmate.

23...gxf6 24.exf6+ Kd8 Black resigned

Checkmate will be coming soon after 25.f7+.

What Hole?

Ah! Another unsound attack with the Jerome Gambit by Yours Truly! At first glance, it looks powerful - but, there is a hole in it. (Or maybe more than one...) Lucky for me, my opponent missed his escape, and perished in rolling thunder.

perrypawnpusher - kenkenaitya
blitz, FICS, 2014

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

The Jerome Gambit.

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6

I like facing this defense, as it allows White to get rid of the annoying Black dark-squared Bishop and to get his "Jerome pawns" rolling.

7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6

10.0-0 Rf8 11.f4

Or 11.f3 as in mrjoker - PhlebasP, ICC, 2009 (1-0,35).

11...Kf7

Alternatives:

11...Qe7 was seen in perrypawnpusher - parlance, blitz, FICS, 2011 (1-0, 20),  perrypawnpusher - obturator, blitz, FICS, 2012 (1-0, 31) and perrypawnpusher - fogab, blitz, FICS, 2014 (1-0, 27);

11...Ng4 was seen in perrypawnpusher - lorecai, blitz, FICS, 2010 (1-0, 47), perrypawnpusher - jgknight, blitz, FICS, 2010 (1/2-1/2, 58) and perrypawnpusher - dkahnd, blitz, FICS, 2011 (24); and

11...Rf7 was seen in mrjoker - Mandragora, ICC, 2008 (1-0, 49) and perrypawnpusher - dkahnd, blitz, FICS, 2010 (1-0, 30).

12.f5 Ne5 13.d4 Neg4 14.Qd3 Kg8 

Black has castled-by-hand, but White already has a small edge.

15.h3 Nh6 16.Bxh6 gxh6 17.Nc3 a6 18.Qe3 Kg7

Rybka 3 gives a very complicated defense starting with 18...Ne8, and including ...Qe7 and ...Qf6 to exchange (or drive) off White's Queen.

19.Qg3+

Here, and for the next few moves, Rybka 3 prefers e4-e5. Then, when I finally play the move, it prefers something different. The reason? See the note to Black's 23nd move.

19...Kf7 20.Qh4 Rg8 21.Qxh6 Rg7

22.e5?

First White should play 22.Rae1.

22...dxe5 23.dxe5 Ng8

Instead, 23...Qd4+ 24.Rf2 Qxe5 gives Black the edge. White must always be wary of the Black Queen check and capture, if he plays the e4-e5 break.

24.e6+ Kf8 25.Qf4 b5

Here Rybka 3 suggests that Black try his luck in a Rooks and pawns endgame (where he is still worse): 25...Nf6 26.Rad1 Qe7 27.Nd5 Qc5+ 28.Ne3 Qe7 29.Ng4 Nxg4 30.hxg4 Bxe6 31.fxe6+ Kg8 32.Qc4 Rg6 33.Rfe1 b5 34.Rd7 bxc4 35.Rxe7 Rg7 36.Rd7 c3 37.bxc3 Re8 38.Rxg7+ Kxg7 39.e7 Kf6.

Now White finishes off the game in sparkling style.

26.Rad1 Qe8 27.f6 Rg6 28.f7 Qe7 29.fxg8Q+ Kxg8 30.Qf7+ Qxf7 31.exf7+ Kf8 32.Rd8+ Ke7 33.f8Q+ Ke6 
Black resigned as I played 34.Re1

Why I Still Play the Jerome Gambit

Let's face it. When it comes to chess playing "strength", I compare to other club players the way the Jerome Gambit compares to other chess openings. 

Still, the "worst chess opening in the world" continues to provide me with interesting positions and creative opportunities (even if I often miss them) - and, by studying my games, I hope to learn more and more about what I should already know...

perrypawnpusher - fogab
blitz, FICS, 2014

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6 

The Database says that I have reached this position 47 times, scoring 80%.

10.0-0 Rf8 11.f4 Qe7 12.Nc3 b6 

Black seems to be multi-tasking here. He prepares to castle-by-hand, puts his Queen on the useful e7 square, and looks to fianchetto his Bishop.

I might as well add two more ideas: harassing White's Queen with 12...Ng4 as in perrypawnpusher - obturator, blitz, FICS, 2012 (1-0, 31); and protecting the d5 square with 12...c6 as in perrypawnpusher - parlance, blitz, FICS, 2011 (1-0, 20). 

13.f5 Ne5 14.d4 Nc4 15.Qf4

This is not an improvement on the straight forward 15.Qd3 which would give White an advantage.

Interestingly enough, the one other game in The Database with this position after 14 moves now saw 15.Qg5 which ended well for White in 32 moves in holofernes - kdosch, FICS, 2001.

15...Nh5

A mistake which should allow White to correct his Queen placement - and more. This is what I meant in my introductory remarks: when I falter, sometimes the Jerome Gambit (admittedly, with the help of my opponent) gives me a hand.

By the way, one way for Black to take advantage of White's uncertainty about Queen placement was to continue to put pressure on the center with 15...c5, although after the tactical tap dance 16.b3 cxd4 17.Nb5 a6 18.Nxd4 Ne5 not a lot has been decided; Black's King is still in the center, and White can try 19.Ba3!?.

16.Qg4 

Why is it that Bill Wall can run his Queen all over the board, and it always looks like he is doing the right thing, while my monarch always seems to look like she's scattered and losing her marbles...?

Instead of the text, 16.Qf3 was correct, with the direct threat to Black's Knight on h5 and the upcoming exposed threat to his Rook on a8, after e4-e5. 

Black can then defend with  16...Qf7 17.e5 Rb8, but White's annoying "Jerome pawn" will advance with 18.e6, creating an interesting tactical situation. If then 18...Bxe6,White can simply capture the Bishop, but he can also try 19.Bg5!? taking advantage of Black's weakness along the e-file, and White's available Rook at a1. This is shown most clearly in the line 19...Bxf5 20.Rae1+ Kd7 21.Re7+ Qxe7 22.Bxe7 Nd2 23.Qxh5 Nxf1 24.Bxf8 Rxf8.

Instead, Black can try to further distract things (after 19.Bg5!?) with 19...Nd2 but the same themes come into effect, to a smaller degree, after 20.Qc6+ Qd7 21.Qxd7+ Bxd7 22.Rfe1+ Kf7 23.Re7+ Kg8 24.Rxd7 Nc4 25.g4 Nf6 26.Rxc7 Rbc8 27.Rxc8 Rxc8 28.Bxf6 gxf6 29.Nd5.

I admit that I looked at these lines with Houdini after the game, but how hard would it have been for a regular, ordinary club chess player to come up with most of this?

At this point I imagine that the ghost of Alonzo Wheeler Jerome was tapping his foot in disappointment. 

16...Nf6 17.Qh4 

Nope. The Queen needed to go to e2, and from there support e4-e5 with a slight edge. 

Now Black can even the game out with the deflating 17...Nxe4 18.Qxe4 Qxe4 19.Nxe4 Bxf5. White would not be losing, but he would not be winning, either.

17...Bb7 18.b3 Na5 19.Bg5 h6 20.Bxf6 Qxf6 21.Qh5+ Rf7 22.e5 dxe5 23.dxe5 Qg5 

24.Qxg5 hxg5 25.Rae1 

Despite White's menacing "Jerome pawns" and Black's broken Kingside structure, the second player has the advantage. His plan to improve his worst-placed piece, however, is not best.

25...Nc6 26.e6 Rf6 27.Nd5 Black resigned

A puzzling outcome, all around. Quite possibly my opponent was simply tired of the game, and surrendering the exchange was the last straw.

Yet, after 27...Rd8 28.Nxf6+ gxf6 Black's Knight and Bishop look  a lot more frisky than White's Rook and two pawns. I would have swapped Rooks with 29.Rd1 Rxd1 30.Rxd1, but then, as long as Black keeps White's Rook off of d7, what is there to worry about?

Chances

What "chances" White has in the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) come from a myriad of sources, not the least of which is opponent loss of focus or intensity. Too many games have ended up "1-0" because the defender did not see the necessity of putting all of his skill to use against a foolish, refuted opening.

perrypawnpusher  - spydersweb
blitz, FICS, 2012

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.f4 Ng6 

Since one of the time-proven strategies to defuse the Jerome Gambit has been returning a piece, this defense can not technically be considered "bad". 

Yet, after 11 moves (see diagram below) the players reach a position in which White has an extra move (f2-f4) in comparison to the line 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Ke7 8.Qxc5+ d6 9.Qe3. So, if Black wants to give up his King's Bishop and post his Knight at g6, the alternative might be a better choice.

9.Qd5+ Ke7 10.Qxc5+ d6 

10...Ke8 is an alternative, as in perrypawnpusher - parlance, blitz, FICS, 2011 (0-1, 22). 

11.Qe3 

Notable is 11.Qf2 Nf6 12.d3 Rf8 13.0-0 Kf7 14.Nc3 Kg8 15.f5 Ne5 16.Bg5 Nf7 17.Bh4 c6 18.Ne2 Ne5 19.h3 Bd7 20.g4 h6 21.Nf4 a6 22.Rae1 Qe7 23.d4 Nf7 24.Ng6 Qd8 25.Nxf8 Qxf8 26.Bxf6 gxf6 27.h4 Kg7 28.Kh2 Qe7 29.Qf4 Re8 30.Rg1 Kh7 31.c3 Rg8 32.Re3 Rg7 33.Reg3 Bc8 34.g5 fxg5 35.hxg5 Nxg5 36.f6 Qf7 37.Qh4 Qxf6 38.Qh5 Qf4 39.e5 dxe5 40.dxe5 Qxe5 41.Kh1 Be6 42.Qd1 Bd5+ 43.Kh2 Nf3+ 44.Kh3 Nxg1+ 45.Rxg1 Qe3+ 46.Kh2 Qf2+ 47.Kh3 Rxg1 White reigned, guest725 - guest114, Internet Chess Club, 2002.

11...Nf6

Alternatives:
11...Kf8, perrypawnpusher - Valseg, blitz, FICS, 2011 (1-0, 39); 
11...Be6 12.f5 Black resigned, perrypawnpusher - MrNatewood, blitz, FICS, 2010; 
11...Bd7 perrypawnpusher - GabrielChime, blitz, FICS,2009 (1-0, 29).

12.0-0

It is probably better to tuck away the King first than create a broad center with 12.d4, as in perrypawnpusher - thinan, blitz, FICS, 2010 (1-0, 31).

Also seen was 12.Nc3 as in mrjoker - PhlebasP, Internet Chess Club, 2008 (0-1, 34).

12...Re8 13.f5 Ne5 14.d4 Neg4 

It's always fun to harass the Queen, but 14...Nc6 was the right idea, as White then does not get much with 15.e5 Kf8 16.e6. Instead, I had planned on 15.Qd3 Kf8 16.Bg5. 

15.Qd3 Kf8 16.Bg5

A bit better might have been the thematic 16.h3 Nh6 17.Bxh6 gxh6 18.Nd2

16...h6 17.Bxf6 

This capture is not actually necessary as 17.Bh4 g5 18.fxg6 leads to an advantage for White. Best for Black after 17.Bh4 would be 17...h5, giving Black's advanced Knight a retreat square. Still, the second player's Kingside looks weakened, and White would probably not be worse.

17...Qxf6 

The Queen is poorly placed only because the Knight is poorly placed. Better was 17...Nxf6 18.Nc3 with an edge to Black. 

18.h3 Ne5

Played perhaps a bit too automatically. Play looks relatively equal after 18...d5 19.hxg4 Rxe4 20.c3 Rxg4 21.Nd2 c6 22.Rae1 Bd7. 

19.dxe5 Qxe5 20.Nc3 

How many times has White's advantage in the Jerome come down to better development, while Black's Queen Bishop sits at home, cutting off his Queen's Bishop?

20...c6 21.Rad1 d5 

A miscalculation. 

22.exd5 c5 

Better, but not saving, was 22...Qe3+ 23.Qxe3 Rxe3 24.dxc6 bxc6. 

23.f6 g5 24.Qg6 Black resigned

Almost

Sometimes the person playing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) gets just enough assistance from the defender that the opening can almost look like it really does lead to a powerful attack...

perrypawnpusher - obturator
blitz, FICS, 2012

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6

7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6

10.0-0 Rf8 11.f4

Equally strong was 11.d4, as in fehim - cybernoid, FICS, 2006: 11...Be6 12.e5 dxe5 13.dxe5 Ne7 14.exf6 Rxf6 15.b3 Nd5 16.Qe4 Qd6 17.Bb2 Rh6 18.g3 Kd7 19.Rd1 Re8 20.c4 Bg4 21.Qxg4+ Black resigned.

Instead, 11.f3 was the introduction to an ultimate "Jerome pawn" game, mrjoker - PhlebasP, ICC, 2009 (1-0, 35).

11...Qe7

I have also faced 11...Rf7 in perrypawnpusher - dkahnd, blitz, FICS, 2010 (1-0, 30) as has Louis Marin, in mrjoker - Mandragora, ICC, 2008 (1-0, 49);

as well as 11...Ng4 in perrypawnpusher - dkahnd, blitz, FICS, 2011 (1-0, 24), perrypawnpusher - lorecai, blitz, FICS, 2010 (1-0, 47), and perrypawnpusher - jgknight, blitz, FICS, 2010 (½-½, 58).

12.Nc3

Also possible was 12.f5 Ne5 13.Nc3 b6 14.d4 Nc4 15.Qg5 Nxe4 16.Nxe4 Qxe4 17.Qxg7 Bxf5 18.Bh6 Rf7 19.Qg5 Kd7 20.Rae1 Qxd4+ 21.Kh1 Nd2 22.Rxf5 Rxf5 23.Qxf5+ Kc6 24.Bxd2 Qxd2 25.Rf1 Re8 26.Qf3+ Kc5 27.Qa3+ Kc6 28.Qa4+ b5 29.Qa6+ Kd7 30.Qxb5+ c6 31.Rf7+ Re7 32.Qb7+ Kd8 Black resigned, holofernes - kdosch, FICS, 2001.

12...Ng4

Also seen is 12...c6 as in perrypawnpusher - parlance, blitz, FICS, 2011 (1-0, 20), although 12...Kf7 with plans to continuing castling-by-hand may be best.

13.Qg3 Bd7 14.f5 N6e5 15.d4 d5

Black returns a piece and undermines White's pawn at f5, but this might be less painfully accomplished (at least the first step) by 15...Nf6 16.dxe5 dxe5.

Now White's game takes a step forward.

16.Nxd5 Qd6 17.dxe5 Nxe5 18.Bf4 Qc5+ 19.Kh1 Nf7 20.Nxc7+ Ke7


21.Nxa8

I was pleased to be the exchange and a few pawns ahead, but 21.Qh4+, continuing the attack on the King, was stronger.

21...Rxa8 22.Bg5+

This was a nervous, short-of-time move. Better was the straight-forward 22.Qxg7.

22...Ke8 23.c3 Bc6 24.Rae1 h6 25.Be3 Qc4 26.Qxg7 Bxe4 27.Qg8+ Kd7 28.Qxa8

I had my clock back under control, and needed only avoid a serious blunder to bring home the point.

28...Qc6 29.Rd1+ Kc7 30.Bf4+ Kb6 31.Qg8 Black resigned

It all adds up

I have mentioned elsewhere GM Bronstein's lighthearted comment that in chess, three small errors tend to add up to one big error. In the following game, Black suffers a loss more because he loses his way against the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxv7+) than because of any great blunder.

7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6

10.0-0 Qe7 11.Nc3 Be6

Black has any number of alternatives, including 11...b6 as in perrypawnpusher - Navarrra, blitz, FICS, 2011, (1-0, 24); 11...Rf8 as in mrjoker - rex3, Internet Chess Club 2009 (1-0, 50),  perrypawnpusher - MRBarupal, blitz, FICS, 2010 (0-1, 31), perrypawnpusher - parlance, blitz, FICS, 2011 (1-0, 20) and perrypawnpusher - chingching, blitz, FICS, 2011 (½-½, 36); 11...Ne5 as in perrypawnpusher - mikelars, blitz, FICS, 2011 (1-0,50); and 11...Kd7 as in perrypawnpusher - parlance, blitz, FICS, 2011 (1-0, 22).

The text encourages White to play f2-f4-f5.

12.f4 Bd7

Losing a tempo.

The alternative, 12...Bc4, was seen in QuadCoreBR - Alecs, blitz, FICS, 2008 (1-0, 27) and perrypawnpusher - ZhekaR, blitz, FICS, 2011 (0-1, 36).

Too risky is 12...Kd7 as in perrypawnpusher - Solaar, blitz, FICS, 2011 (1-0, 33).

13.f5 Ne5 14.d4 Nc4 15.Qd3 Nb6

The "Jerome pawns" are rolling and White has the advantage.

16.Bg5 h6 17.Bh4 Qf7

Moving out of the pin on the Knight, but it is interesting to see what Houdini recommended after the game: 17...Rd8 18.e5 dxe5 19.dxe5 Bc6 20.exf6 gxf6 21.Qg3 Kd7 22.Rae1 Qc5+ 23.Qf2 Qxf2+ 24.Rxf2 Rde8 25.Rfe2 Rhf8 26.Rd1+ Kc8 27.Rxe8+ Rxe8 28.Bxf6 Nc4 29.Nd5 Bxd5 30.Rxd5 Ne3 31.Re5 Rxe5 32.Bxe5 Nxf5.

analysis diagram








White's attack has been neutralized, but his extra pawn and Bishop vs Knight should win in the end.

18.e5 dxe5 19.dxe5

19...Nfd5

This raises the level of danger, but Houdini's suggestion 19...Qc4 20.Qxc4 Nxc4 21.exf6 will lead to a two-pawn advantage for White, any way.

The tactics all go White's way now.
