Out of sight, out of mind

When I was putting together yesterday's Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) post – a long game with analysis and diagrams can take a couple of hours – I noticed that I had referenced a game that was in my database, but had not yet shown up on this blog. Playing through the game, I could understand the oversight: it's another bad game.

I suppose that I can take some comfort in the fact that I scored 2.5 point in those 3 bad games – that almost makes up for the poor play.

blitz 10 0, FICS, 2009
1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 The Semi-Italian opening.


4.0-0 Bc5 5.Bxf7+ 5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ Ng6
Some of my games have goen otherwise: 7...Ke6 8.Qf5+ Kd6 9.d4 Bxd4 ( 9...Qf6 10.dxe5+ Qxe5 11.Rd1+ ( 11.Bf4 Qxf4 12.Qxf4+ Kc6 13.e5 d5 14.b4 Nf6 15.bxc5 Ne4 16.Qf7 Nxc5 17.Qxg7 Be6; 11.Bf4 Black resigned, perrypawnpusher - joejox, FICS 2009) 11...Bd4 12.Qf8+ Ke6 13.Qe8+ Kf6 14.Qf8+ Ke6 15.Qe8+ Kf6 drawn, perrypawnpusher - Joyus, FICS, 2007) 10.Rd1 c5 11.c3 Ne7 12.Qh5 Kc7 13.cxd4 cxd4 14.Qxe5+ d6 15.Qxd4 Nc6 16.Qxg7+ Bd7 17.Bf4 Rg8 18.Qxh6 Qe7 19.Bxd6+ Qxd6 20.Qxd6+ Black resigned, perrypawnpusher - Lakritzl, FICS 2009;

And 7...Kf6 8.Qf5+ Ke7 9.Qxe5+ Kf7 10.Qd5+ Kf6 11.e5+ Kg6 12.Qxc5 d6 13.exd6 Qxd6 14.Qxd6+ cxd6 15.Nc3 Bf5 16.d3 Rc8 17.Be3 a6 18.Bd4 Nf6 19.Rae1 Rhe8 20.f3 Kh7 21.Bxf6 gxf6 22.Rxe8 Rxe8 23.Kf2 Kg6 24.Re1 Rc8 25.Re7 Rb8 26.Ne4 Bxe4 27.fxe4 b5 28.Rd7 Rb6 29.c3 b4 30.c4 b3 31.a3 f5 Black resigned, perrypawnpusher - bergeruw, FICS 2007

8.Qd5+

As I've said (see "Ugly"), I continue to play this nudge; few others do. For example: 8.Qxc5 d6 9.Qc4+ Be6 10.Qe2 Nf6 11.f4 Re8 12.f5 Bxf5 13.Rxf5 d5 14.e5 Qd7 15.Qh5 c6 16.Nc3 Qc7 17.d4 c5 18.Nxd5 Qd8 19.exf6 gxf6 20.Rxf6+ Qxf6 21.Nxf6 Black resigned, abhailey - cumelen, net-chess, 2008

8...Kf6

Or 8...Kf8 9.Qxc5+ d6 10.Qe3 N8e7 11.d4 Kg8 12.Nc3 Kh7 13.f4 Rf8 14.f5 Nh8 15.g4 Kg8 16.g5 hxg5 17.Qxg5 Nf7 18.Qg3 Nc6 19.f6 g5 20.Bxg5 Nxg5 21.Qxg5+ Kf7 22.Qg7+ Ke6 23.d5+ Ke5 24.Qg3+ Kd4 25.Qd3+ Ke5 26.Qg3+ Kd4 27.Qd3+ Ke5 28.Qg3+ Kd4 29.Qd3+ Ke5 30.Qg3+ Kd4 31.Qd3+ Ke5 32.Qg3+ Kd4 drawn, perrypawnpusher - pascalwilliams, blitz, FICS, 2007;

Or 8...Ke8 9.Qxc5 Qe7 10.Qe3 Nf6 11.Nc3 c6 12.f4 b6 13.f5 Ne5 14.d4 Ba6 15.dxe5 Qxe5 16.Re1 Kf7 17.Qf3 Rhe8 18.Bf4 Qc5+ 19.Be3 Qb5 20.Bd4 Qxb2 21.e5 Nd5 22.e6+ Kg8 23.Qg4 Nxc3 24.Qxg7 checkmate, perrypawnpusher - Cibola, blitz, FICS, 2009

9.Qf5+ Ke7 10.Qxc5+ Ke8 11.f4 d6 12.Qe3

Too much of a reflex action. One subtle difference between the regular Jerome Gambit and the Jerome Gambit coming out of the Semi-Italian opening is that here I had the option of 12.Qh5, pinning and eventually winning the Knight on g6.

That's worth remembering for next time.

12...Qf6 13.f5 Ne5 14.d4 Nc4

Now, where should the Queen go?

15.Qg3

What made sense was 15.Qd3, not this move which drops a pawn.

15...Qxd4+ 16.Kh1 Kd7 17.Nc3 b6

As long as Black is behind in development, White has hope.

18.Bf4 Ba6


This move is consistent, but turns out not to be good. I wish I had realized how not-good it was.

19.Rad1 Qc5


Sometimes there are things going on in a game that neither player recognizes. I was totally unaware that the Black Queen had to go to f6 to stay out of trouble.

20.Qxg7+ Ne7 21.e5

This seemed consistent and good to me, but Rybka later saw it as a blunder, preferring 21.b4 Rag8 22.Qxg8 Nxg8 23.bxc5 bxc5.

21...Rag8 22.e6+ Kc6


On the other hand, Rybka didn't like this move one bit, either, preferring 22...Kd8.

Offsetting blunders, and White is now better.

23.Qxe7 Re8 24Qd7+Kb7 24.b3

Ah, the irony: Rybka shows how "simple" the position actually was – 25.Rd5 Qc6 26.b4 Na3 ( 26...Qxd7 27.exd7 Rd8 28.b5) 27.b5 Nxb5 28.Nxb5 Qxd7 29.exd7 Re7 30.f6 Rxd7 31.Bxh6 Rf7 32.Bg7... I think I'll leave the computer out of the discussion for a while.

25...Nd2 26.Bxd2 Bxf1 27.Rxf1 Qd4

28.f6 Rhf8

In the face of the advancing pawns, Black's play is deteriorating.

29.Nb5 Qxd2 30.Qxc7+ Ka6 31.Qxa7+ Kxb5 32.Qd7+


Overlooking the mate (that I paid two good pieces for!) with 32.Qa4+ Kc5 33.Qc4.

Well, I'm down a Rook now, but those advanced pawns have to count for something.

32...Ka6 33.e7 Qe2 34.Rg1

34...Rxf6 35.Qxe8 Rf1

Threatening mate-in-2, but it is Black's last hurrah...

36.Qa8+ Kb5 37.e8Q+ Qxe8 38.Qxe8+ Kb4 39.Rxf1 Black resigned

Diagnosis: Misplaced Knight


It has been said that if one piece sits poorly in a chess game, the entire position becomes poor for that player.

I think that remark usually refers to games played above the level of those involving the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), but it does appear true that in the following game, my opponent's Queen Knight (and to some extent, his King Knight) caused him a lot of difficulty.

Of course, I was cooperative: as Genrikh Chepukaitis said “You need not play well - just help your opponent to play badly”

perrypawnpusher - Kotimatka
blitz 6 5, FICS, 2009

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6


The Semi-Italian.

4.0-0 Bc5 5.Bxf7+ Transposing to a Jerome Gambit, of course. I think the extra 0-0 helps White more than the extra ...h6 helps Black.

5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ Ng6
8.Qd5+

I continue to prefer Alonzo Wheeler Jerome's "nudge" here, instead of the direct capture of the Bishop.

An alternative, from the current Chessworld Jerome Gambit Thematic Tournament, is 8.Qxc5 d6 9.Qc4+ Be6 10.Qe2 Nf4 TN 11.Qf3 g5 12.d3 Nf6 13.Bxf4 Bg4 14.Qe3 gxf4 15.Qxf4 Qd7 16.Nc3 c6 17.f3 Be6 18.Qe3 Rag8 19.Rf2 Rg6 20.f4 Ng4 21.Qf3 Ke8 22.f5 Rf6 23.fxe6 Qxe6 24.Qh3 Rxf2 25.Qh5+ Kd7 26.h3 Rxg2+ 27.Kxg2 Ne3+ 28.Kf2 Nxc2 29.Rc1 Rf8+ 30.Ke2 Nd4+ 31.Kd1 Rf1+ 32.Kd2 Nf3+ 33.Kc2 Rxc1+ 34.Kxc1 Ng5 35.h4 Qh3 36.Qxh6 Qf1+ 37.Kc2 Qf2+ 38.Kb3 Qb6+ 39.Kc2 Qf2+ 40.Kb3 Qb6+ 41.Kc2 Qf2+ 42.Kb3 Draw, Black Puma - TWODOGS, JGTourney4, ChessWorld, 2009

8...Ke8 9.Qxc5 d6
Earlier this year I faced 9...Qe7 10.Qe3 Nf6 11.Nc3 c6 12.f4 b6 13.f5 Ne5 14.d4 Ba6 15.dxe5 Qxe5 16.Re1 Kf7 17.Qf3 Rhe8 18.Bf4 Qc5+ 19.Be3 Qb5 20.Bd4 Qxb2 21.e5 Nd5 22.e6+ Kg8 23.Qg4 Nxc3 24.Qxg7 checkmate, perrypawnpusher - Cibola, FICS, 2009

10.Qe3 Ne5

I am sometimes surprised that my opponents think so little of the Jerome Gambit that they act as if anything can be played against it. White is close to having an equal game after this move.

11.d4 Ng4 12.Qg3 N8f6

This unnecessarily complicates things.

13.Nc3
The position is trickier than I thought when I was playing. For example, after 13.f3, Black's Knights prance around: 13...Nh5 14.Qe1 Ngf6 15.g4 Nxg4 16.fxg4 Bxg4 17.Nc3 Kd7 and the game is about even.

13...Be6

Fritz8 prefers 13...Nh5 14.Qd3 Ngf6 15.f4, giving White a small advantage.

14.h3 Bc4

Black needed to complicate things with something like 14...Nh5, for example 15.Qf3 (eye on the Knights!) Rf8 16.Qe2 (the same) Ngf6 17.e5 Kf7 (castling-by-hand!) 18.exf6 Nxf6 19.Re1 Qd7 20.Ne4 Kg8 and White is a pawn up, but things are still challenging: if 21.Nxd6 then 21...Bxh3.

15.Re1 Qd7 16.hxg4
Gathering in the wayward Knight.

16...Nxg4 17.f3 Nf6 18.e5 Nh5

19.exd6+

A bit better was 19.Qh4 Qf7 20.exd6+ Kf8 21.Re7 Qg6 22.d5, snaring the Black Bishop; but the text is sufficient.

19...Kf7 20.Qh2 g6 21.Re7+ Black resigned

Get back on the horse...

If you fall off of a horse, you're supposed to get right back on it, or you'll be too scared to ride again... After my last loss via blunder (see "My Turn Again") I knew I had to saddle up the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) or one of its relatives, and take off at a gallop.

The following game, a Semi-Italian Jerome Gambit, followed a line of play that I was familiar with, but didn't really know, bringing to mind David Freeman's comment that "The more you know, the more you realise how much you don’t know — the less you know, the more you think you know."

8.Qf5+

Rybka 3.0 suggests as better the Queen maneuver 8.Qh3+ Ke7 9.Qc3 d6 10.d4 and after 10...Bxd4 11.Qxd4 Nf6 White does better than in the game, although Black still has the advantage.

I didn't know that.

8...Kd6 9.d4



An alternative: 9.Rd1 Ne7 10.Qh5 g6 11.Qh3 Bd4 12.Qa3+ Bc5 13.b4 Bd4 14.c3 Bxf2+ 15.Kxf2 Rf8+ 16.Ke3 White resigned, prettyhip1 - cubs0_0, GameKnot, 2007.

9...Bxd4

A tougher defensive idea is 9...Qf6 10.dxe5+ Qxe5 11.Rd1+ ( 11.Bf4 Black resigned, perrypawnpusher - joejox, blitz, FICS, 2009) 11...Bd4 12.Qf8+ Ke6 13.Qe8+ Kf6 14.Qf8+ Ke6 15.Qe8+ Kf6 1/2-1/2 perrypawnpusher - Joyus, blitz, FICS, 2007.

10.Rd1 c5

Black does better with 10...Qf6 11.Rxd4+ Ke7; but, make no mistake, even with the text he has the advantage.

11.c3 Ne7 12.Qh5

Or 12.Qh3 Qb6 13.cxd4 cxd4 14.Qa3+ Ke6 15.f4 N5c6 16.f5+ Kf7 17.Nd2 Re8 18.Nc4 Qc7 19.Nd6+ Kf8 20.Nxe8 Kxe8 21.Qf3 Ne5 22.Qg3 Kf8 23.Bf4 d6 24.Rac1 Qa5 25.f6 N7g6 26.Bxe5 Qxe5 27.Qxg6 Be6 28.Qxg7+ Ke8 29.Qe7 checkmate, joev6225 - liverpool, GameKnot, 2006.


Now Black can continue his defense with 12...Qe8, but decides to give back one piece, and instead gives back two.

13.cxd4 cxd4 14.Qxe5+ d6 


White is now better, and Black's game goes to pieces.

Take the advantage and run...


Sometimes the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) leads to messy positions. In those situations, it's better to have more material and more time; but it's equally important to have an idea what to do and what not to do.
perrypawnpusher - LethHansen
blitz game 3 12 FICS, 2009

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6
The Semi-Italian game.

4.0-0 Bc5 5.Bxf7+ 5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ Kf8 New to me. I have seen 4 other moves: 7...Kf6 (
Bergeruw), 7...Ng6 (pascalwilliams, cibola), 7...Ke6 (Joyus, joejox), and 7...g6 (Islanderchess, wadada).


8.Qxe5 Bd6

A new kind of counter attack. I like it.

9.Qd4 Qh4 10.g3

A nervous move, since the thematic 10.f4 was ok, i.e. 10...Bxf4 11.g3.

10...Qh5 11.Qe3 c6
Black has the advantage of a piece for two pawns. He needs to develop quickly and safeguard his pawn. If White is to have a chance, he needs to develope even quicker.
12.d4 b6 13.e5 Bc7 14.f4

This pawn play is all very Jerome-ish, but Rybka 3, after the game, suggested instead 14.b3 followed by 15.Ba3 with more attention to the Black King.

14...Ne7 15.Nc3 b5

Probably 15...d5 was better, although that would give White an advanced, protected passed pawn.

16.Ne4 Bb7 17.Nc5 Bc8 18.f5 d6 19.Ne6+ Kg8


Black has a defense, but it begins with 19...Bxe6. This oversight swings the game towards White.

20.Nxc7 Nxf5 21.Qf4 Rb8 22.exd6 Bd7


23.Bd2 Rf8 24.Rae1 Kh7



The clocks are ticking. LethHansen is untangling. I'm hoping not to blunder.

25.Qe5 Qh3 26.Bf4 Black lost on time.

Ooooops...

It can be a lot of fun showing off my Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) games – even the losses – or, as in the case below, my Jerome-ized games, but it's a little embarassing to find in the middle of a "good" win a really bad move...


perrypawnpusher - Cibola
blitz FICS, 2009

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6

The Semi-Italian Game, not necessarily safer than 3...Bc5.

4.0-0 Bc5 5.Bxf7+ 5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ Ng6

8.Qd5+ Ke8

Or 8... Kf8 as in perrypawnpusher - pascalwilliams, blitz 3 0, FICS, 2007 (1/2-1/2, 32) and abhailey - cumelin, net-chess.com, 2008 (1-0, 21).

9.Qxc5 Qe7 10.Qe3 Nf6 11.Nc3 c6 12.f4 b6


Up to here we have a pretty normal Jerome Gambit-style scenario: White hopes he can use his two extra pawns to create mischief before Black can get his extra piece to settle things.

13.f5

Fritz 8's suggestion is interesting, suggesting play across the whole board, and a balanced game after: 13.Qg3 Nf8 14.e5 Nh5 15.Qf3 g6 16.d4 Ba6 17.Rd1 Ng7 18.Ne4 Kd8 19.d5 Kc8 20.a4

13...Ne5 14.d4 Ba6


If you can counter a tactical threat with a stronger one of your own, that is a good thing: so Black threatens my Rook while I "merely" threaten his Knight – well, not exactly, but that was what my opponent was thinking. Instead, the Knight should retreat to f7.

15.dxe5 Qxe5



If 15...Bxf1 then 16.exf6 Qxf6 17.Kxf1. Now I have my piece back, and am up a pawn.

16.Re1 Kf7 17.Qf3 Rhe8 18.Bf4 Qc5+ 19.Be3 Qb5


Clearly a case, Jerome Gambit Gemeinde member Pete Banks ("blackburne") would say, of serious shock and awe.

20.Bd4

Clearly a case of "short attention span chess". When I looked closer at the board after my move (most experts recommend looking at the board before you move) I was appalled at my oversight. Oooops...

20...Qxb2



Well, I suppose it would be too much to expect him to let me have a second chance to capture his Queen... I do have a lot of pawns and pieces pointed at his King, however.

21.e5 Nd5

This falls in with White's plans. Better was 21...Qb4, attacking the Bishop on d4. White's attack can then proceed, but slower: 22.Rad1 Kg8 23.Qg3 Nd5 24.Ne4 Qf8 25.Nd6 followed in a few moves with the pawn break f5-f6.

22.e6+



22...Kg8 23.Qg4 Nxc3

Ending the game, but 23...Re7 24.Nxd5 lead to only misery as well after 24...Qxd4+ 25.Qxd4
cxd5 26.Qxd5 Bb7 (what else??) 27.Qd6
