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.


perrypawnpusher - episodeninetynine
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

Semi-Good

I can understand the excitement of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) and occasionally that can get a player ahead of himself or herself. The Jerome motif can be fun against the Semi-Italian Opening (1.e4 e5 2.Nf3 Nc6 3.Bc4 h6) but, as the following game shows, it is best to wait for Black to play ...Bc5 first.


Fuller - Vallance-Gallant
Women's Open Championship of Canada
ICCF, 2008



1.e4 e5 2.Nf3 Nc6 3.Bc4 h6
4.Bxf7+ Kxf7 5.0-0

There's no use trying 5.Nxe5 Nxe5 6.Qh5+, as after 6...Ng6 there is no Bishop to capture on c5. I've gotten away with this oversight against marapr and my buddy abhailey has done the same against cumelen, but it's not the right way to play the Jerome Semi-Italian.

White's situation is similar to that in playing the "modern" Jerome Gambit: it's hard to work up play without her opponent's help.

5...d6 6.Nc3 Nf6 7.Nd5
7...Be7 8.c3 Re8 9.d4 Bg4

White keeps offering material, and Black keeps declining – and developing.

10.h3 Bxf3 11.Qxf3 exd4 12.c4 Kg8


Black has castled-by-hand, and White's game continues to go from bad to worse.

13.b4 Nxd5 14.cxd5 Nxb4 15.Qg3 Bg5

16.a3 Bxc1 17.axb4 Bb2 18.Rab1 Bc3 19.b5 Rxe4 20.Qf3 Qe7 21.b6 axb6 22.Ra1 Bxa1 23.g3 Re1 24.Qd3 Qe2 25.Qxe2 Rxe2 26.Rxa1 Rxa1+ 27.Kg2 d3 28.Kf3 Raa2 29.h4 Rxf2+ 30.Ke4 d2 31.Ke3 d1Q 32.Ke4 Qa4+ 33.Kd3 Rf3 checkmate

To paraphrase Albert Einstein, one should play the Jerome Gambit as soon as possible, but not sooner.

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

24.Qxg7 checkmate

Semi-Italian Jerome Gambit

I have a habit of giving the "Jerome Gambit treatment" to related openings, if I think I can get away with it (see "Blackburne Shilling Jerome Gambit" and "Blackburne Shilling Jerome Gambit 2").


Take the "semi-Italian" opening, as referred to by Euwe, 1.e4 e5 2.Nf3 Nc6 3.Bc4 h6, and played at times by GM Pavel Blatny (and many nervous club players who fear Nf3-g5).

perrypawnpusher - bergeruw
blitz game FICS, 2007

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


4.0-0

One early morning on FICS I was in such a hurry to Jerome-ize this opening that I fired off 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Ke7 8.Qxe5+ Kf7 only to realize (of course) that there was no enemy Bishop on c5 to pick up! So I had to weasel my way out: 9.Qd5+ Ke8 10.0-0 c6 11.Qd4 c5 12.Qc3 d6 13.f4 Be7 14.d4 b5 15.dxc5 dxc5 16.Qxg7 Bf6 17.Qg6+ Ke7 18.Nc3 Bb7 19.e5 Qd4+ 20.Kh1 Bh4 21.Qg7+ Ke8 22.Qxh8 Kf7 23.Qh7+ Kf8 24.Qf5+ Bf6 25.exf6 Nxf6 26.Nxb5 Be4 27.Nxd4 Black resigns, perrypawnpusher - marapr, FICS, 2007


4...Bc5 5.Bxf7+

I think that adding 0-0 to the regular Jerome Gambit line is more helpful to White than adding ...h6 is to Black. In any case, the game is no longer the quiet affair hoped for by the second player.

5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ Kf6

Black moved his King, instead, to e6 in a humorous gamelet of mine, where both sides were plagued by nerves from the onset, and I foolishly forced a draw in a won position: 7...Ke6 8.Qf5+ Kd6 9.d4 Qf6 10.dxe5+ Qxe5 11.Rd1+ Bd4 12.Qf8+ Ke6 13.Qe8+ Kf6 14.Qf8+ Ke6 15.Qe8+ Kf6 Game drawn by mutual agreement.. perrypawnpusher - Joyus, blitz game, FICS, 2007

Black can, as an alternative, block the check: 7...Ng6 8.Qd5+ ( 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 lost on time in a busted position, abhailey - cumelen, net-chess.com 2008) 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 in time trouble, with a winning position, I forced the draw, perrypawnpusher - pascalwilliams, blitz game, FICS 2007

8.Qf5+ Ke7 9.Qxe5+ Kf7 10.Qd5+ Kf6



11.e5+ Kg6 12.Qxc5 d6 13.exd6 Qxd6 14.Qxd6+ cxd6



Black is simply two pawns down, and his King's increased activity is not sufficient compensation.
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

A further ten moves has not improved Black's lot.

25.Re7 Rb8 26.Ne4 Bxe4 27.fxe4 b5 28.Rd7 Rb6 29.c3 b4 30.c4 b3 31.a3 f5 Black resigns
