Good Luck



From the Good-Luck-Is-Better-Than-A-License-To-Steal Department comes the following end position from a Blackmar Shilling Jerome Gambit game


heckifiknow - pianazo, blitz, FICS, 2011
With White to move, it is stalemante.

Don't go away -- It gets better



After an opening oversight shared with my opponent (I wondered why there were no other examples of his 6th move in The Database) the game goes on to some interesting attacking ideas. So, don't get upset and go away; the game gets better.


 
perrypawnpusher - acwizard
blitz, FICS, 2011

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


The Semi-Italian Opening.

4.0-0 Bc5 5.Bxf7+

The Semi-Italian Jerome Gambit

5...Kxf7 6.Nxe5+ Kf8


In the Sorensen Variation (see "Battle Again") of the Jerome Gambit, this King move is playable, even laudible. However, in the Semi-Italian Jerome Gambit... 

7.Nxc6

Of course 7.Ng6+ would win at least the exchange, depending on if the Knight can extract itself.

I think I was patting the dog and telling her I was busy when I made this move... (That's my story and I'm sticking to it.)

7...dxc6 8.d3 Ne7

By transposition 8...Nf6 led to perrypawnpusher - vladchess, blitz, FICS, 2011 (½-½, 46) with the relevant continuation 9.Be3 Qe7 10.d4 Bb6 11.f3 Kg8 12.Nc3 Kh7 13.Qd3 g6

9.Be3

Rybka 3 prefers to preserve the Bishop with 9.c3 Bb6 10.d4 and a roughly equal game.

9...Bb6

Black does not want to open the f-file with 9...Bxe3 10.fxe3+  but his King could have safely gone to g8 (and even on to h7) maintaining an edge.

10.Nc3

Instead, 10.d4 kept White's dark-squared Bishop and kept the game balanced. Exchanging the Bishop with 10.Bxb6 cxb6 was seen in stretto - TommyN, FICS, 2008.

10...Kg8 11.Bxb6

Impatience. Again, the way to keep things level was with 11.d4, but the choice of one strategy over another is always easier to see after the game is over.

11...cxb6 12.f4 Kh7 13.d4 Bd7


Here we have a confrontation between the "Jerome pawns" and Black's extra piece. The game is about equal.

14.f5 Rf8

Black has neatly castled-by-hand.

15.Qd3 Rf6 16.g4 g5

This pawn move upsets the balance of the game. It would have been more prudent to simply return the Rook with 16...Rf8.

17.e5 Rf7

This move creates unnecessary grief. Again, after the Rook retired with 17...Rf8, White can try 18.Rae1 Be8 19.Ne4 Kh8 but he still has to be careful with his pawns, lest Black liquidate them by returning his piece. 

18.e6 Black resigned

Not only does White's e-pawn fork a couple of pieces, his f-pawn threatens to advance with a discovered check.

Asterisk

In the notes to "Still Worth Knowing" I mentioned that The Database had 10 games with the line 1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.0-0 Na5. Since one was played recently, I thought I'd present the contests.


ghostshadowrook - VeniceOdyssey
FICS, 2011

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



The Semi-Italian Opening

4.0-0 Na5

If anything, even less of a good idea than 3...Na5.

5.Bxf7+ Kxf7 6.Nxe5+


6...Ke8

Or 6...Ke6 7.d4 c5 8.Qg4+ Ke7 9.Bg5+ hxg5 10.Qxg5+ Ke8 11.Qxd8+ Kxd8 12.Nf7+ Ke8 13.Nxh8 cxd4 14.Nd2 b6 15.c3 dxc3 16.bxc3 Rb8 17.Rfe1 Kd8 18.e5 Nh6 19.Ng6 Bc5 20.Ne4 Bb7 21.Nxc5 bxc5 22.Rad1 Nf5 23.e6 Bc6 24.e7+ Nxe7 25.Nxe7 Rb7 26.Nxc6+ Nxc6 27.Rd5 c4 28.a4 Rb3 29.Rg5 Rxc3 30.Rxg7 Ra3 31.Rd1 Nb8 32.Rg8+ Kc7 33.a5 Rxa5 34.Rc1 d5 35.Rg7+ Kc6 36.Rg6+ Kc5 37.h4 d4 38.Rg5+ Kb4 39.Rxa5 Kxa5 40.Rxc4 Kb5 41.Rxd4 Nc6 42.Rd5+ Kb6 43.h5 a6 44.h6 Ne7 45.Rd6+ Ka5 46.Rxa6+ Kxa6 47.h7 Kb6 48.h8Q Ng6 49.Qf6+ Kb5 50.Qxg6 Kc5 51.f3 Kd5 52.Kf2 Ke5 53.Qe4+ Kf6 54.Ke3 Kf7 55.Kf4 Kf6 56.Qc6+ Ke7 57.Ke5 Kf7 58.Kf5 Ke7 59.Ke5 Kf7 60.g4 Ke7 61.Kf5 Kf7 62.Qc7+ Kf8 63.Kf6 Kg8 64.Qg7 checkmate,  ctstraightedge - oirimil, FICS 2010;


Or 6...Ke7 [here Black resigned in yenalexxx - skimtnbikekayak, blitz, FICS, 2010] 7.Qh5 Kd6 8.Nf7+ Ke7 9.Nxd8 Kxd8 10.Qxa5 b6 11.Qc3 Nf6 12.d3 d6 13.f4 Ng4 14.e5 dxe5 15.fxe5 Bc5+ 16.d4 Be7 17.Qc6 Rb8 18.Qg6 Rg8 19.Nc3 Ba6 20.Rf7 c5 21.Qxg4 cxd4 22.Qxd4+ Ke8 23.Rxe7+ Kxe7 24.Qd6+ Ke8 25.Qxb8+ Kf7 26.Qxa7+ Kg6 27.Qxa6 Kh7 28.Qd3+ Kh8 29.Qh3 Re8 30.Bxh6 gxh6 31.Qxh6+ Kg8 32.Qg6+ Kf8 33.e6 Ke7 34.Qf7+ Kd8 35.Qd7 checkmate, perrypawnpusher - Butin, blitz, FICS, 2009.

7.Qh5+ g6

With Black's pawn on h6, this does not close out any danger.

Instead, 7...Ke7 8.Ng6+ (8.Qf7+ Kd6 9.Qd5+ Ke7 10.Ng6+ [10.Qf7+ Kd6 11.Qd5+ Ke7 12.Ng6+ White won by ajudication, JoeDemir - dogbrother, FICS 2010] 10...Ke8 11.Nxh8 Nc6 12.Qf7 checkmate, rosti - carifano, FICS, 2010) 8...Ke6 (8...Kd6 9.Qe5+ Kc6 10.Qd5+ Kb6 11.d3 Nf6 12.Be3+ c5 13.Qf5 d6 14.d4 Bxf5 15.dxc5+ dxc5 16.exf5 Rg8 17.b4 Nc6 18.Nd2 Ka6 19.bxc5 Bxc5 20.Bxc5 Qxd2 21.Rab1 b6 22.Be3 Qxc2 23.Rfc1 Qe4 24.Rxc6 Qxc6 25.Ne7 Qc2 26.Rc1 Qxa2 27.Nxg8 Nxg8 28.g4 Nf6 29.h3 Kb7 30.g5 hxg5 31.Bxg5 Ne4 32.Be3 Rc8 33.Rxc8 Kxc8 34.Kg2 Qd5 35.f3 Qa2+ 36.Kf1 Ng3+ 37.Ke1 Qe7 checkmate, valiantknight - Monkee, FICS, 2000) 9.Qf5+ Kd6 10.Qd5 checkmate perrypawnpusher - TheTrueDamaBlanca, blitz, FICS, 2009).

8.Qxg6+ Ke7

And here Black resigned.

Instead, Divtwo - HotCaldron, FICS, 2010, continued to the same end: 9.Qf7+ Kd6 10.Qd5+ Ke7 11.Qxa5 d6 12.Ng6+ Ke8 13.Nxh8 Qf6 14.Qh5+ Ke7 15.Ng6+ Kd7 16.Nxf8+ Qxf8 17.Qf5+ Kd8 18.Qxf8+ Kd7 19.Qxg8 Kc6 20.Qc4+ Black resigned,

Odd Twin


The following game was played at FICS the day after my game against MRBarupal (see"Battle Again"). This time Black faces no mere pawn-pusher, but an actual, stronger, knight-pusher...


Knightpusher - MRBarupal
blitz, FICS, 2011

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


4...Kxf7 5.Nxe5+ Kf8

The Sorensen Variation.

6.Nxc6 dxc6 7.0-0 Nf6 8.d3 Bg4 9.Qe1 Qe8 10.Be3


The moves of this game are exactly the same as those in perrypawnpusher - MRBarupal, blitz, FICS, 2011. Perhaps for that reason, or perhaps for another, here Black resigned.

"Objectively," the game is still a bit better for the second player.

Barely Legal


Denied the chance for a Jerome Gambit, and facing a foe with a strategy that had been successful against me in past games, I found a way to update an old chess strategem of my own.

perrypawnpusher - koek
blitz, FICS, 2011


1.e4 e5 2.Nf3 Nc6 3.Bc4 d6




Sigh. No Jerome Gambit today: a Philidor Defense by transposition, or maybe a Hungarian Defense.

4.0-0 Bg4

Planning to gang up on my pinned Knight at f3 and cause a breakup of the pawn wall in front of my King.

5.Nc3

Going along with Black's plan.

Last year Koek and I played one game that continued 5.d4 White resigned; and another that continued 5.h3 Bh5 6.d3 Nd4 White resigned.

5...Nd4



I've been having a hard time finding games that follow this move order, but I did discover Hansen, S. - Briz, P., Denmark, 1974, that now continued 6.d3 Nxf3+ 7.gxf3 Bh3, showing the Kingside damage that I was trying to avert.

Now for something completely different.

6.Nxe5

Ah, yes, the idea from Legal de Kermeur - St. Brie, Paris 1750: 1.e4 e5 2.Nf3 d6 3.Bc4 Bg4 4.Nc3 g6 5.Nxe5 Bxd1 6.Bxf7+ Ke7 7.Nd5#

6...Bxd1

Black needed to play 6...dxe5, but who could resist a "free" Queen?

7.Bxf7+ Ke7 8.Nd5 checkmate

Blackmar Diemer Gambit


I received a very pleasant email from Guido de Bouver of Grimbergen, Belgium, the other day,


Hello Richard,
I have been following your posts on your blog regularly.
I am not an 1.e4 player but enjoy the attacking positions in the gambit.
I have created a new blog http://blackmardiemergambit.blogspot.com/ on the Blackmar Diemer Gambit.
Please have a look - you might want to add some words on your blog and add a link, so I get some additional publicity!
Thanks for your help and keep up the good work !
Guido
Readers will see that I have added a link to Guido's web page.

After all, not everybody plays the Jerome Gambit all the time, but they still like to attack. (And if you open with 1.e4, looking for the Jerome Gambit, and your opponent plays 1...d5, you can counter his Center Counter with 2.d4 and go for the BDG!)

You should also know that Guido has written a very exciting book on the Blackmar Diemer Gambit (I have a copy, and when Chessville.com comes back online you will be able to see my review): Attack with the Blackmar Diemer, A Computer Analysis of the Teichmann, Gunderam, O'Kelly lines in the Blackmar Diemer Gambit.

International Master Gary Lane, in his "Opening Lanes" column at ChessCafe.com has written about the book "My advice if you have a love of the opening is to seek it out and buy it at the first opportunity."

According to Tom Purser, at Tom's BDG Pages, Guido is working on a second BDG volume, including the Euwe and Bogoljubow Defenses.

Chess Life

Readers who have access to the March 2011 issue of Chess Life are urged to turn to page 44 and take a look at Grandmaster Lev Alburt's "Back to Basics" column, titled this time around "How to Trick the Trickster". It features my Blackburne Shilling Jerome Gambit game against PunisherABD.
