Trick or Treat / Sing Along

From Jerome Gambit Gemeinde Member Bill Wall:

Rick,


After reading your doom and gloom article, I wanted to play the same variation, but got a different one with 6...Bxd4 instead of 6...Bb4. But instead of doom and gloom, it was Trick or Treat as I tricked my opponent with some exchanges, including the Queens, and was treated with a win in 21 moves.

Wall,B - Bersekergang
blitz 10 0, FICS, 2011


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


4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4


7.Qxd4 Qf6

As old as the unfinished correspondence game, Alonzo Jerome - D.P. Norton, 1876.

8.Qc5 Qd6

For some very odd reason, this game reminds me of the Blue Man Group music video, featuring Dave Matthews; I imagine the song referred to was titled "d6".

9.Qxd6 cxd6


10.0-0 Nf6 11.Nc3 a6 12.Rd1 Ke7 13.b3 b5 14.Ba3 Nf7 15.e5 Ne8


16.exd6+ Nexd6 17.Ne4 Bb7 18.Nxd6 Nxd6 19.Rxd6 Kd8 20.Rad1

20...Bc6

A slip, no doubt leaving Bersekergang feeling, well, blue.

21.Rxc6 Black resigned

Over

I noticed in preparing yesterday's game (see "Done in by Greed") that I had overlooked the following one. Here it is, without too much over-compensation in terms of notes and references...

perrypawnpusher - Navarrra
blitz, FICS, 2011

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


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6


7.Qf5+ Ke7

Probably a shocked response, as it returns two pieces.

8.Qxe5+ Kf7


Both possible King moves are equal, but the text gives Black an opportunity to go wrong if he is careless, as opposed to playing 8...Kf8 directly.

9.Qd5+

There is, of course, nothing wrong with the direct 9.Qxc5.

9... Kg6

Here is some of that aforementioned carelessness, though. The King wanders away from home and into danger.

Instead, perrypawnpusher - Leontes, FICS, 2009 continued 10... Qe7 11. Qxe7+, when Black resigned, acknowledging the uphill fight in a Queenless middlegame, 2 pawns down.

10.Qf5+ Kh6 11.d4+ g5


12.Qxc5 d6 13.Qc3 Qe7 14.Qe3 Bf5

An oversight that does not help.

15. exf5 Qxe3+ 16. Bxe3 Nf6


With Queens off of the board, it appears that Black's King is out of danger but at a cost.

17.h4 Kg7 18.hxg5 Nd5 19.Nc3 Nxc3 20.bxc3 Rae8

Those nasty "Jerome pawns" – all 8 of them.

21.Kd2 b5  22. f6+ Kf7 23.Rh6 a6 24.Rah1 c6 25.Rxh7+ Rxh7 26.Rxh7+ Ke6


Black resigned, in light of 27.f7 Rc7 28.Rg7 Rf8 29.g6 d5 Rg8

Done in by Greed

The following game was a tense, balanced affair, travelling through known territory for a dozen moves and on into a balanced middle game. When I went pawn-grabbing with my Queen, however, my opponent struck back hard, eventually checkmating me.

Lesson?

perrypawnpusher - ZhekaR
blitz, FICS, 2011

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


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


7.Qd5+ Ke8 8.Qxc5 Nf6

The Database shows that mrjoker has a win, a loss, and a draw against 8...Qe7.

9.Nc3

Or 9.d3, which can traspose to the game.

9...Qe7 10.Qe3 d6


11.0-0 Be6

Black has many alternatives, including: 11...b6 as in perrypawnpusher - Navarrra, blitz, FICS, 2011 (1-0, 24) [Hmmm, I don't think that I have posted this game yet - RK]; 11...Rf8 as in mrjoker - rex3, CC, 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).

12.f4 Bc4

Earlier this year I faced 12...Kd7 in perrypawnpusher - Solaar, blitz, FICS, 2011 (1-0, 33).

13.d3 Ba6


14.Bd2 b6 15.Rae1 Kd7 16.Qh3+ Kd8 17.Nd5

Planning to use the opened e-file for my Rook, but 17.e5 was probably a better idea.

17...Nxd5 18.exd5 Qd7 19.Qg3 Qf5




The game is about even, as White has two pawns, better development, and a safer King as compensation for his sacrificed piece.

20.c4 Re8 21.Rxe8+ Kxe8 22.Re1+ Kd7 23.Qe3 Rf8 24.g3 c5 25.dxc6+

After the game Rybka 3 suggested instead 25.b4 cxb4 26.Bxb4.

25...Kxc6 26.Bc3 Rf7 27.Qe8+ Qd7 28.Qe4+ Kc7 29.Qa8




A fool's errand. That pawn on a7 will turn out to be very, very expensive.

29...Bb7

This is good enough for advantage, but 29...Nxf4 was already crushing (i.e. 30.gxf4 Qg4+, etc.).

30.Qxa7

The only chance to keep on playing lay with 30.Qe8.

30...Qc6

Again, good; but, again 30...Nxf4 was much stronger.

31.Re4 Re7 32.Bd4 Rxe4 33.dxe4 Ne7 34.b4 Nc8 35.Qa3 Qxe4 36.Qb2 Qe1 checkmated




Wow. Nice work by ZhekaR to punish my pawn-grabbing!

Gloom and Doom

Although I have occasionally been accused of having the demeanor of Mr. Rogers on muscle relaxants, I do have times when I am serious, or even downright gloomy take the "Update: 8...Qf6" post, for example.

Here is another cautionary tale.

Teterow - geneve
lightning, FICS, 2011

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


4...Kxf7 5.Nxe5+ Nxe5 6.d4

This move, rather than 6.Qh5+, was originally Alonzo Wheeler Jerome's preference.

6...Bb4+


This is an odd move, but it reflects an inconvenient fact, that Black has many ways of dealing with the Jerome Gambit, including choosing which piece(s) he wants to return – and in what way.

The move deserves a look, if only because it has been played by dismissive humans ("sure, why not?") and calculating computers.

7.c3 Qh4


How's that for a kick in the head? Just when you were saying to yourself, "Well, at least he didn't play 6...Qh4!?"

By the way, as long as I am mentioning 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf6+ Kxf7 5.Nxe5+ Nxe5 6.d4 Qh4, it is necessary to correct and update some of what I wrote in "A Pie-in-the-Face Variation" about a year and a half ago.

Today The Database contains 167 games with the 6.d4 Qh4 line. That's 26 games less than I thought that I had in November 2009, but perhaps that is a result of subsequently cleaning up my databases.

Also, 50 of the current games – about 30% of the 6.d4 Qh4 line – are now human-vs-human encounters, as opposed to only 8 (4%) in the original post. White's scoring has dropped from 50% to 29% amongst humans, which is in the right direction, but it is the ridiculously high 74% for all of the games in The Database. (Again, that is the impact of computer-vs-computer games largely selected by the source for White wins.)

8.cxb4

The dynamics of the current position are very similar to that of the position without 6...Bb4+ 7.c3. What that means is that White's best move here after 7...Qh4 has to be 8.0-0. Rybka 3, given 5 minutes per move in "blunder check" mode, further suggested 8...Nc6 9.cxb4 Qxe4 10.b5 Nce7 11.Re1 Qf5 12.Re3 Qxb5 13.Nc3 Qb6 14.Qh5+ Qg6 15.Qc5 b6 16.Qxc7 Qc6 17.Qe5 d6 18.Qg5 h6 when Black has an edge (about 3/4 of a pawn).





analysis diagram







I am not convinced that this is the best path for Black to take, however.

If I were playing the defense, after 6...Bb4+ 7.c3 Qh4 8.0-0. I would prefer the as-yet-unplayed 8...Ng4, answering 9.h3 with 9...Be7. Perhaps Rybka downgrades this line a bit because White can exchange Queens with 10.Qxg4.

Anyhow, the text move is very dangerous and Black takes charge.

8...Qxe4+ 9.Qe2

A bit better is 9.Kf1, covering the g2 pawn, but after 9...Qd3+ 10.Qe2 Qxe2+ 11.Kxe2 Nc6 Black is clearly better in an uncomplicated game. As it it, the game transposes into this line.

9...Qxe2+ 10.Kxe2 Nc6


11.Rd1 Nxb4 12.Na3 Nf6 13.Re1 Re8+ 14.Kf1 Rxe1+ 15.Kxe1 d5


16.Be3 Bf5 17.Nb5 c6 18.Nc3

A final slip. 

18...Nc2+ 19.Ke2 Nxa1 Black resigned


Looks like there is more work to be done on the 6...Bb4+ variation. With wins in The Database by Jerome Gambit Gemeinde members Darrenshome, HauntedKnight, jfhumphrey, stretto, Teterow, yorgos and, of course, Bill Wall – there is plenty of hope.

Upon Reflection




Every once-in-a-while I get the sense that I am learning from my mistakes and using in later games what I learned from earlier games. Upon reflection, this gives me a small sense of accomplishment.

perrypawnpusher - smarlny
blitz, FICS, 2011

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


4...Kxf7 5.Nxe5+ Kf8

Black is content with the material advantage that he has, and backs his King away from danger. Let White do what he will!

I am always tempted now to play 6.Qh5, the Banks Variation (after Jerome Gambit Gemeinde member Pete Banks) but I am still uncertain how to best meet 6...Qe7.

6.Nxc6 dxc6 7.0-0 Ne7



The alternative, 7...Nf6, is as old as Jerome,A - Brownson,O, Iowa, 1875 (½-½, 29).

7...Bd6 was seen in perrypawnpusher - Lark, blitz, FICS, 2009 (1-0, 18) and 7...Be6 in perrypawnpusher - CorH, blitz, FICS, 2009 (0-1, 74).

8.d3

After the game Rybka 3 pointed out that here White can already "punish" his opponent for his inaccurate 7th move by playing for a draw with 8.Qf3+ Kg8 9.Qb3+ Kf8 10.Qf3+ Kg8 11.Qb3+, etc.

As if.

8...Ng6 9.Be3 Bd6



Not wanting to open the f-file for White's Rook with 9...Bxe3, Black positions the Bishop on the attacking diagonal b8-h7.

The piece continues to shuffle from square to square, however, and I wonder if, upon reflection, my opponent would have preferred to simply have exchanged it.

10.f4 Qh4 11.Nd2 Kf7

To castle-by-hand, but, somehow, this never happens.

12.Nf3 Qe7 13.e5 Bc5 14.d4 Bb6



15.Qd3

Preparing f4-f5, but the move was playable immediately, thanks to a tactical trick that would not have been too hard to find, if I had looked for it: 15.f5 Bxf5 16.Ng5+ followed by 17.Rxf5.

15...h6

Obviously my opponent saw the Knight check from g5. This gives the "Jerome pawns" time to rumble, however.

16.f5 Nf8

This game was beginning to feel like my game against irak: comparing White's Rooks (linked) and Black's Rooks (on their home squares, two pieces between them), there has to be an attack coming.

17.f6 gxf6 18.exf6 Qe6



Taking the pawn on f6 would have been deadly, but the danger remains.

19.Rae1 Qd5 20.Ne5+ Ke8 21.c4 Qa5



White now has a number of ways to win. The flashiest would be to sacrifice two pieces with 22.f7+ Kd8 23.Bg5+ hxg5 24.Nxc6+ bxc6 25.Qe3 and mate is inescapable.

I found something simpler.

22.Bd2 Qxa2 23.Ng6+

I thought that the loss of a Rook would prompt my opponent to resign, so I looked no further, missing all of the fun that could happen after 23.f7+.

23...Kd8 24.Nxh8 Qxb2 25.Nf7+ Black resigned

The Chess Improver

I know that I have mentioned GM Nigel Davies website "The Chess Improver" at least in passing on this blog, but I wanted to specifically encourage Readers to stop by and enjoy the varied and always informative content that he has assembled. Recently video clips from the BBC program The Master Game have been posted: interesting, top-level chess with comments by the players themselves. Great stuff!

I have also enjoyed Davies' books, and this link will take you to a number of reviews.

(One last thing: "The Chess Improver" contains a link to this blog; but, of course...)

Sunday Book Review: Why You Lose at Chess, 2nd Ed.


Why You Lose at Chess 2nd Ed
Tim Harding
Dover (2001)
softcover, 130 pages
figurine algebraic notation




I suppose that you can sense a pattern in the chess books that I have mentioned lately, the last two being Surprise in Chess and Danger in Chess: How to Avoid Making Blunders.

There are a number of links to be made between these books, Why You Lose at Chess,(*) and the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) and I suppose I should get around to reviewing the titularly more inclusive Why We Lose at Chess (emphasis mine) by Colin Crouch and the more distanced Catalog of Chess Mistakes by Andy Soltis  but the real hook for me (besides the fact that I have loved every book by Dr. Harding that I have ever read) with Why You Lose at Chess (emphasis mine), which left me laughing out loud, was Harding's main theme of the book
Before you can play well, you must stop playing badly.
Ain't it the truth??

The table of Contents promisess a killer's row of self-induced pain

Why You Lose Material
Why You Lose In The Opening
Why You Lose In The Endgame
Why You Lose In The Middle Game
Why You Lose In Good Positions
Why You Lose In Difficult Positions
Why You Lose On Time
Why You Lose At Correspondence Chess
Why You Lose To Computers

Each chapter not only has examples of chess players behaving badly, and coming to no good ends, but also contains explanations by the author about what is going on, what should be going on, and how things could be corrected.

Of special interest is the chapter "My Most Instructive Loss" where IM Harding, IM Cenek Kottnaur, IM George Botterill and IM Bob Wade all share their insights.

I found his "Acknowledgements & Bibliography" chapter interesting as well, where Harding recommends Gerald Abrahams' The Chess Mind, Kotov's Play Like A Grandmaster and Think Like A Grandmaster and Krogius' Psychology in Chess. (I touched on all of these a while back in "My Chess Psychology Book Shelf".)

Harding maintains an optimistic, at times humorous, but always encouraging outlook

Three results are possible in a game of chess – win, loss and draw. This book is intended to cut down drastically on your rate of losses, by recognising the danger signals in time, and by analysing what went wrong in the games you do lose.
To let a potential win slip into a draw is a disappointment but, for most players, it cannot compare with the blow to one's confidence that comes from losing in a serious game. The occasional loss to an acknowledged superior is no bad thing, as an insurance against overconfidence and for the lesson in technique it may give you. However, most of your losses are probably of a more painful variety.
Most of the games you play are likely to be against opponents of approximately your own standard; yo win some and you lose some, yet you always feel that you could do better. By a little extra study beforehand, and more effort while at the board, you could turn that 50 per cent success rate into 80 or 90 per cent and so raise yourself into a new class of competition...
I've read the book through once and am working on it again. After all, an 80 or 90 per cent success rate in the Jerome Gambit would be awesome!
