Tied Up, or How Much Is A Queen Worth?

There's nothing like receiving the gift of your opponent's Queen in the first twelve moves of a game, especially when you are in a critical line of one of the Jerome Gambit's (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) refutations.

Why, it only took me 32 more moves to end the game!

Huh?

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

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


This is one of the classical refutations of the Jerome Gambit.

Modern players unfamiliar with the Jerome may prefer 6...Ng6, 6...Kf8 or 6...g6 because this line feels more dangerous, but the King is actually safe in the middle of the board – and Black has two extra pieces, as well.

My first conclusion about my opponent, who was playing without much hesitation: he either doesn't like to return material, or he knows what he is doing.

7.Qf5+ Kd6 8.f4 Qh4+


Ah, yes, the "Nibs" defense – or counter-attack, if you will. It's beginning to look like my opponent elyza has stopped by this blog a time or two.

9.g3 Nf3+

Wow! Seriously cutting-edge play. For some background, check out "Repairing a Variation (Part 1), (Part 2), (Part 3) and (Part 4)".

10.Kd1
If you are going to battle the Queen-sac line, I think 10.Kd1 is the right move. If you are looking toward the endgame, 10.Kf1 is to be preferred – "Repairing a Variation (Part 4)"
The alternative: 10.Kf1 Qh6 (10...Qf6 11.Qd5+ Ke7 12.Qxc5+ Kd8 13.Kg2 d6 14.Qd5 Ne7 15.Qd3 Nd4 16.e5 dxe5 17.c3 Bf5 18.fxe5 Qc6+ White resigned, perrypawnpusher - james042665, Chess.com, 2008) 11.Qd5+ Ke7 12.Qxc5+ Qd6 13.Qxd6+ cxd6 14.c3 g5 15.Kf2 g4 16.h3 d5 17.hxg4 dxe4 18.d3 d5 19.g5 h6 20.dxe4 dxe4 21.Nd2 Nxd2 22.Bxd2 Bg4 23.Be3 Ke6 24.Rh4 Kf5 25.Bd4 Rh7 26.Rah1 h5 27.Ke3 Ne7 28.R4h2 Nd5+ 29.Kd2 b6 30.Re1 Re8 31.Be3 Rd8 32.Kc2 Rc7 33.a3 Rcd7 34.Bd4 b5 35.Be5 Rc8 36.Kb1 a5 37.g6 b4 38.axb4 axb4 39.g7 b3 40.Bd4 Kg6 41.Kc1 Kf5 42.Rhh1 Nb4 43.Kd2 Rxd4+ White resigned, perrypawnpusher - Temmo, JG3 thematic, Chessworld, 2008.

10...Qf6

Or 10...Qh6 11.Qd5+ Ke7 12.Qxc5+ Qd6 13.Qxd6+ cxd6 14.c3 Nf6 15.d3 b6 16.Ke2 d5 17.Kxf3 dxe4+ 18.dxe4 Bb7 19.Re1 Kf7 20.Nd2 Rhe8 21.g4 d5 22.e5 d4+ 23.Kg3 dxc3 24.bxc3 Nd5 25.Bb2 Rad8 26.Ne4 Nf6 27.Nd6+ Kf8 28.Nxb7 Rd7 29.Ba3+ Kf7 30.Nd6+ Rxd6 31.exd6 Ne4+ 32.Rxe4 Rxe4 33.Kf3 Rc4 34.d7 Rxc3+ 35.Ke4 Black resigned, perrypawnpusher - electrahan, blitz FICS, 2009

11.e5+

Fail.

This looked like a great move at the time, but the right path had already been laid out for me by Louis Morin ("mrjoker"), that of simply collecting the dark-squared Black Bishop: 11.Qd5+ Ke7 12.Qxc5+ d6 13.Qxc7+ Bd7 14.Nc3 Rc8 15.Nd5+ Ke6 16.Qxb7 Qd4 17.f5+ Ke5 18.Qxd7 Nf6 19.Qe6 checkmate, guest2365 - guest2535, Internet Chess Club, 2004

11...Ke7

Wow.

Black was taken in by the move, too. Had he played, instead, 11...Nxe5 12.fxe5+ Qxe5 he would have shown that my pawn advance was a blunder.

12.exf6+ Nxf6


Game over? Hardly. My opponent probably wants me to show him that I have more than just a good sense of humor in the opening. Or maybe he is aware that sometimes I get... tired.

13.Qxc5+ d6 14.Qe3+ Kf7


15.h3

Naturally not 15.Qxf3 Bg4 winning the Queen.

15...Nxd2 16.Bxd2 Re8


17.Qf2 Kg8 18.Re1 Bxh3


I don't mind giving up the pawn. I'm trying to untangle my pieces on the Queenside.

19.Nc3 Bg4+ 20.Kc1 c5 21.b3 b5 22.Kb2 b4 23.Ne2 Ne4


This is getting annoying.

24.Qe3 a5 25.Qd3 a4 26.Ng1 a3+ 27.Kc1


27...Rad8

I was getting frustrated. Being this tied up was ridiculous!

28.c4

This is not a BLUNDER, but it is clearly an INACCURACY – see "Italian Game Anti-Fried Liver Defense (Part 2)" – since 28.Rxe4 was the best move. (Would it have ended the game? Probably not.)

Here is my new annotation for "I should have had some coffee":


28...Nf2 29.Rxe8+ Rxe8 30.Qxd6 Ne4


31.Qd5+ Be6

A slip. It helped.

I knew that I was going to have to go all the way to checkmate with my opponent, though, and time was running low.

32.Qxe4 Bf7 33.Qg2 Bh5 34.Kc2 Bg6+


35.Kd1 Be4 36.Qf2 Bf5 37.Nf3 Bg4


38.Be3 Rd8+ 39.Ke1 Rd3 40.Rd1


At last!

40...Rc3 41.Rd8+ Kf7 42.Ne5+ Ke7 43.Qd2 Bf5 44.Qd6 checkmate

"How to Win Without Thinking"


It's time to point out to all readers that the latest BCM has an article written by Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) Gemeinde member Pete Banks ("blackburne"), titled "How to Win Without Thinking."

Check it out!

British Chess Magazine : November 2009
Cover photo: Magnus Carlsen wins in Nanjing

Nanjing - it was Magnus Carlsen all the way at the ‘Pearl Spring’ tournament – which could prove to be one of the most significant turning points in the past decade. Ian Rogers was present to witness Carlsen’s star turn and annotate all his key games.

Short-Efimenko - Nigel Short faced a tough assignment in Ukraine, playing one of that country’s best young grandmasters. He lost the first game – could he recover? Read on...

Paignton - this well-loved congress is almost as traditional as Devon cream – Keith Arkell writes about one of his favourite events and annotates some games.

Italian Game Anti-Fried Liver Defense (Part 2)


Do you like kibitzers?

Neither do I.

They always know the moves you should have played, the moves your opponent could have played, and they're never shy about sharing all of that.

There is a world of difference between kibitzing and annotating, despite their allegedly similar goals.

I mention all this because after Welton Vaz ("Gandybh" at Chess.com) completed his Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) treatment of the Semi-Italian Opening (1.e4 e5 2.Nf3 Nc6 3.Bc4 h6) (see "Italian Game Anti-Fried Liver Defense Part 1"), he submitted it for analysis to the computer at Chess.com.

The result was surely educational, but it was also relentless. I chuckled my way through the game – it was a fun, exciting, typical Semi-Italian Jerome Gambit – because of the computer's notes. A computerized kibitzer – what will they think of next?

Italian Game Anti-Fried Liver Defense (Part 1)


Jerome Gambit Gemeinde member Welton Vaz sends us a Chess.com link to an enjoyable discussion on the play of 1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 – known on this site as the "Semi-Italian Opening" (after Euwe) – as a way of avoiding the Fried Liver Attack 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5 Nxd5 6.Nxf7

Although one of the Chess.com posters complained about 3...h6 "I hate when players play this as it is an insult to the Italian" there was no suggestion on the website, either in the discussion or the related 21 games given, that White could return the "insult" of 3...h6 by transposing to the Jerome Gambit with, say, 4.0-0 Bc5 5.Bxf7+.

Of course Welton sent one of his games where he provided that "insult" – which we will see in "Italian Game Anti-Fried Liver Defense (Part 2)".

By the way, Grandmaster Boris Alterman has a 6-part series on the Fried Liver Attack on his website, along with instruction on a whole list of gambits, including the Danish, Evans, Max Lange and Morra.

I note that Alterman has two books forthcoming, one on gambits with White and one on gambits with Black. Of the first, he writes
The Alterman Gambit Guide: White Gambits is both an opening book and an instructive manual. Sharpen your tactics and learn to play dynamic attacking chess while studying the most entertaining gambits. Lines covered include:Evans Gambit, Panov Attack, Morra Gambit, Philidor, Danish Gambit, Urusov Gambit, Morphy Attack, Cochrane Gambit, Max Lange Attack, Fried Liver Attack and Milner-Barry Gambit
For those who like their liver fried, there is also a book by NM Dan Heisman on The Computer Analyzes the Fried Liver / Lolli.

Half-way There



I seem to be playing against the Blackburne Shilling Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4) a lot, lately. I'm not sure why – probably just coincidence. I'm still giving it the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) treatment, though.

perrypawnpusher - mbranimir
blitz 12 0, FICS, 2009

1. e4 e5 2. Nf3 Nc6 3. Bc4 Nd4


4. Bxf7+ Kxf7 5. Nxe5+ Ke8



6.Qh5+ g6 7. Nxg6



Black usually plays 7...hxg6 here, although I've also faced 7...Nf6. My opponent now plays an interesting and logical move, first seen in perrypawnpusher - Iourotors, blitz FICS, 2009 (0-1, 37).

7...Nxc2+


This takes the Black Knight out of range of the White Queen. If, instead, 7...hxg6 then 8.Qxg6+ Ke7 9.Qg5+ Ke8 10.Qe5+ Qe7 11.Qxd4 Bg7 when White has 4 pawns for his sacrificed piece, in an unclear position.

8. Kd1 Nxa1


Sometimes half of a good plan turns out to be a bad plan after all. The proper move instead of the text was 8... hxg6, when everything is pretty unclear. Of course, White would always have 9.Qxg6+ Ke7 10. Qg5+ Ke8 11. Qg6+ etc, forcing the draw; or he could try 10.Kxc2 or 10.d3.

Certainly this line bears further investigation – but not today.

9. Nxh8+ Ke7 10. Qe5 checkmate

Tired


Lately my chess play has been sub-par, especially when playing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) and related openings. I'm thinking not so much of my game against CorH, which was a decent affair, but of another loss that I'm still coming to terms with – and of the following game. Perhaps I've just been a bit tired lately.

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


4...Kxf7 5. Nxe5+ Nxe5 6. Qh5+ g6



As Blackburne played almost 125 years ago.

7. Qxe5 Nf6



Okay, not exactly like Blackburne. Blackburne played 7...d6 and got a complicated game and a crushing victory. Whistler played 7...Qe7 and got the same.

I've been here before, and quite possibly my opponent has not.

8. Qxc5 d6 9. Qd4


An experiment I probably won't repeat.

9...c5 10.Qd3 Re8


Black has been avoiding grabbing a pawn  ...Nf6xe4 (to be answered by 0-0) perhaps because he didn't see it. 

11.f3 d5 12.Nc3 dxe4 13.Qxd8 exf3+



This is a tactical oversight that should lose a Rook to the simple 14.Qxe8+. My response was a blunder – so much so that my opponent spent some time trying to figure it out, as he had seen his own error, as often sadly happens, right after playing it.

14.Kf2 Rxd8 15.gxf3



Sadly, my advantage is now just one paltry pawn, which could now be minimized further by the accurate 15...c4.

There was nothing left to do but try to make something of the pawn.

15...Bf5 16.d3 Re8 17.Bg5 a6 18.Ne4 Bxe4 19.fxe4 c4


20.Rhf1 Kg7 21.Bxf6+ Kxf6 22.Kg3+

Probably 22.Ke3+ was a bit better.

25.Rf7+ Kh8 26.R1f3 h5 27.Ra7 Ra8 28.Rxa8 Rxa8 29.d4



The win is pretty straight-forward now.

29...Kg7 30.e5 Rf8 31.Rxf8 Kxf8 32.Kf4 Kf7 33.Kg5 a5 34.d5

Jerome Gambit: Probably Had Nothing To Do With It


Unlike yesterday's game (see "Inspired by the Jerome Gambit: A True Story"), today's game likely had nothing to do with the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+). I present it because it's a fun, quick game – and it has that "evil" move 4.Bxf7+.


Pazderic, Nickola - Hosford, Michael
Washington Invitational, 2009
notes by Pazderic, from the June 2009 issue of Northwest Chess
I arrived at my table awake just enough to notice that Michael seemed a bit edgy,perhaps because he woke up to two losses and last place after two rounds. I thought I would try to unbalance the game immediately to cross him up. How does one do this? Well, I suppose most chess players who followed Fischer would agree:
1.e4!
Michael didn't think too long and replied:
1...Nc6!?

I was a bit relieved; for I was bleary eyed and, thus, not so sure I could handle one of the trickier black defenses any better than my opponent. (Is not, as Lasker said, "the threat stronger than the execution"?—of course, one must still be able to execute...)
I thought for a couple of seconds and rejected 2. d4, knowing Black would be very happy to advance d5 or e5 and either develop his king bishop early or maneuver his knight (after 3. d5) to g6 via e7—when he could test my center with f6 and c5. I also considered 2. Nc3, when White invites Black into a classical set up. In any case,
the Nimzowitsch defense is a little passive and, thus, a little dubious. To provoke the opponent into advancing too far too fast is one goal of this defense. I thought I might catch Black off guard if I reversed the strategy by playing:
2.Bb5

With this move, White invites Black to advance his pawns against the bishop but without any claim to the center, as in the Ruy Lopez. I also thought that should Black venture 2....d5, I could always chop the knight and play my queen to the weakened white squares via e2 for a slight edge. 2...e5 leads to the Ruy Lopez, and I doubted that any Nimzowitsch player would want that. 2...Nf6 is given by my chess engine as the main line; I'm sure I would have attempted 3. Nc3 in reply.
2...Nd4
Bam! The question is put to the bishop immediately. But also instantly I began to scheme of ways to push his knight back into weird positions with a timely c3. The first choice was the natural 3.Ba4, and after 3....b5, I thought White could try at once 4.c3! Then I had a brain wave, reasoning "If I play Bc4 and Black plays the audacious 3...b5, I can probably sac the bishop on f7." That seemed even more off kilter than the solid 3. Ba4, 4. c3 plan. So,
3.Bc4 b5   
Michael played this quickly and, as I thought, audaciously. I didn't really calculate much at this point. I simply saw that black must capture, expose his king to check via h5, and either put his king on f6 or open up his white squares (and the juicy targets on a8 and d4) with a dreary g6. So, merrily I played
4.Bxf7+
At this point Michael said something, which I do not recall, and tipped over his king. In disbelief, I quickly wrote 1-0 on my score sheet, turned and handed it to Fred Kleist, the Tournament Director, and left the commotion.three times; each time White won in 40-55 moves, as I recall. But in practical play, this is no guarantee.



Michael should not have resigned, as he told me the next day. The best plan is to play 5...g6 and to force White to take on d4 or a8 after 6. Qd5+. White has material, but Black can generate some counterplay against the queen. I had my engine play the position
I'm not really proud of this game. But I did use a little counter-psychology, as expressible within the 64 squares, to take advantage of a perceived temporary weakness in my opponent's psychologicalarmor. I am not sure that this is a good way to play generally, but it worked in this case.
