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.

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.

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



34...b4 35.b3 c3 36.h4 Kg7 37.e6 Kf8 38.Kxg6 Ke7 39.Kxh5 Kd6 40.Kg6 Kxd5 41.e7 Black resigned

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.

Inspired by the Jerome Gambit: A True Story


I found the following game on the ChessKnot.com website, annotated by the winner. I've added a few notes, but mostly I'll let the game and the player of the White pieces speak for themselves.

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6
I saved this game because it was an experimental game that worked, 5.b4 was the first time I ever implemented a successful gambit on the spur of the moment and linked it together to win this blitz game in under 60 seconds.


This move seemed a bit peculiar to me as it was preempting my dark-squared bishop from sitting at g5 w/o even knowing if I had planned to fianchetto it to b2. Plus it neglected development of the pieces.
4.Nc3 Nge7


Poor move, IMO, as it blocks in the bishop & queen, prolonging development & castling.
5.b4
Noticing a familiar setup and lack of developed pieces, I offer the pawn to draw the knight away from protecting e5, with a certain surprise awaiting.
5....Nxb4
He takes!
6.Bxf7+


Combined with a sacrifice I learned from the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+), except now there's no pesky knight covering the e5 pawn!
6...Kxf7 7.Nxe5+ Ke8


7...Kg8 would have held out longer 
[After 7...Kg8 Black has the usual beginning Jerome Gambit advantage, whereas after the text, he is busted. - Rick]

8.Qh5+

[I hate to interrupt the Jerome Gambit flow here, but the quickest kill was 8.Qf3 first then: 8...Nf5 9.Qh5+ Ke7 10.Nd5+ Kd6 and Black loses his Queen to 11.Nf7+ - Rick]


8...g6 9.Nxg6 Nxc2+




[Tempting, but Black should instead reinforce g6 with 9...Rg8 so that after 10.Nh4+ he can block with 10...Ng6, for example: 11.Nxg6 Qg5 12.Qxg5 hxg5 - Rick]


10.Kf1
I moved away from the knight in hopes of sacrificing the inactive rook for another critical tempo.
10...Nxg6
mate in 2...
11.Qxg6+ Ke7
stalemated king
12.Nd5
