Another Odd Thing

Sacrifice unsoundly, fall behind in development, send the Queen out to hunt pawns...

Doesn't sound like much of a recipe for victory, does it? Oddly, that kind of describes the way that I played the following game. Wins with White in the Jerome Gambit are often odd things.

perrypawnpusher - Solaar
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 d6 9.Qe3 Nf6


The Database has 82 games with this position. White scores 70%. This is my 29th time here, scoring 81%.

10.0-0 Qe7 11.Nc3

The alternative is 11.d3, although transpositions are likely. 

11...Be6

Looking for trouble.

Rybka 3 suggests 11...Kf7, while 11...Rf8 was seen in perrypawnpusher - MRBarupal, blitz, FICS, 2010 (0-1, 31); 11...Ne5 was seen in perrypawnpusher - mikelars, blitz, FICS, 2011 (1-0, 50); and 11...Kd7 was seen in perrypawnpusher - parlance, blitz, FICS, 2011 (1-0, 22).

12.f4 Kd7

Odd, perhaps planning to castle-by-hand on the Queenside; but returning the piece, intentionally or otherwise.

Better was 12...Bc4 as in QuadCoreBR - Alecs, FICS, 2008: 13.d3 Ba6 14.b4 b6 15.b5 Bb7 16.f5 Ne5 17.d4 Neg4 18.Qg3 h5 19.h3 Nh6 20.e5 Ne4 21.Nxe4 Bxe4 22.Bg5 Qd7 23.e6 Qxb5 24.Bxh6 gxh6 25.a4 Qe2 26.Rf2 Qc4 27.Qg7 Black resigned.

13.f5 Bxf5

Slightly better was 13...Bc4 14.d3 Ne5 15.dxc4 Nxc4 16.Qd4 Ne5, when Black would be down a pawn, but he would have pressure and play against the backward White pawn on e4.

14.Rxf5

Was Solaar expecting me to play 14.exf5? If so, after 14...Qxe3+ 15.dxe3 Ne5 14.e4 the game would have reached the position mentioned in the note to Black's 13th move, only with Queens off the board and it being Black's move. White would still have an edge.

14...Rae8 15.d3 Kc8


The difficulty for Black here is that even though he is better developed and White's center is under pressure, there is time for White's Queen to go pawn-hunting.

16.Qxa7 Rhf8 17.Bg5

Also possible was 17.Qa8+ Kd7 18.Qxb7 but I decided to save that for later,

17...Qe6 18.Bxf6 Rxf6 19.Rxf6 Qxf6 20.Rf1 Qe5


21.Qa8+

After the game Rybka 3 pointed out the more ferocious 21.Rf5 Qe6 22.Rb5 Kd7 23.Rxb7 Rc8 24.Nb5. I was content to be a few pawns up and head toward the endgame.

21...Kd7 22.Qxb7 Nf4 23.Qb5+ Qxb5 24.Nxb5 Rf8 25.Nc3 c6 26.g3 Ne6 27.Rxf8 Nxf8


28.Kf2 Ne6 29.Ke3 c5 30.Ne2 g5 31.c3 Kc6 32.d4 c4

A slip that ends the game quickly, rather than slowly.

33.d5+ Black resigned

A Tale of Threes

My first three Jerome Gambit games against MRBarupal, I lost.

My second three (counting the one below), I won.

This most recent game overlaps a couple of earlier games, making a third interesting "three". 

perrypawnpusher - MRBarupal
blitz, FICS, 2011

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


4...Kxf7 5.Nxe5+ Kf8

My first three games (0-3) against this opponent continued 5...Nxe5 6.Qh5+ Ng6. The next three (3-0) continued 5...Kf8.

There are plenty more Jerome Gambit refutations for us to explore.

6.Nxc6 dxc6 7.0-0 Nf6


8.d3 Bg4 9.Qe1 Qd7


Varying from 9...Qe8 which appeared in  perrypawnpusher - MRBarupal, blitz, FICS, 2011 (10. Be3 Bd6 11.f4 Nh5 12.e5 Be7 13.f5 Black resigned) and the following day in Knightpusher - MRBarupal, blitz, FICS, 2011 (10.Be3 Black resigned).

Fritz8 doesn't see much difference between 9...Qd7 and 9...Qe8, although it slightly prefers a third move, 9...Kf7.

10.Be3 Be7 11.f4 Re8


12.Nd2 h5

Developing his final piece, with aggressive intentions? Or preparing a pawn formation against an expected avalanche of "Jerome pawns"? 

13.Nf3

After the game Rybka 3 was critical of this move, preferring Nd2-c4-e5 as the proper way for the Knight to advance to the center. After the text, Black can simply exchange the piece off  which he promptly does.

13...Bxf3 14.Rxf3 g6


This is a complicated position. After the game Rybka 3 preferred sending the Knight to g4 to exchange off the Bishop at e3, keeping Black's edge.

15.f5

Playing to open lines against the enemy King, but this could turn risky, as White is behind in development. Rybka 3's suggestions show much more patience, with a focus on putting the Queen and Bishop on the a1-h8 diagonal before breaking through.

15...Rg8 16.e5 Ng4 17.fxg6+

Rybka 3 looked at the position of the two Black Rooks and suggested 17.f6 instead, with a complicated mess to follow: 17...Bd6 18.d4 Kf7 19.Bf4 g5 20.Bg3 h4 21.Qe4 Rh8 22.h3 hxg3 23.hxg4 Kf8 (Fritz 8 prefers 23...Bf8) 24.Re3 Rxe5 This is Rybka's idea 25.dxe5 Bc5 26.e6 Qh7 27.Kf1 Qxe4 28.Rxe4 Rh1+ 29.Ke2 Rxa1




analysis diagram









Black has a slight advantage.

17...Kg7


18.Bf4 Qe6 19.h3

Fortunately for me, my opponent now overlooks a Bishop check from c5, which would have strengthened his game. It was more prudent for me to play 19.c3 Ref8 20.d4 first, and after 20...Nh6 21.Qe2 Kxg6 the game would be about even, according to Rybka 3.

19...Nh6 20.Qe4 Nf5 21.Raf1


The game remains complex: is Black defending or attacking on the Kingside? Or both?

In the meantime, White has completed his development, but the pawn on g6 is lost, and his attack is going nowhere. After a few exchanged pieces, Black's edge will become clear.

21...h4

Putting a cramp in White's Kingside and makes an outpost for his Knight at g3, but Rybka 3 preferred 21...Nh4 22.Rg3 Ref8 23.d4 Nxg6 24.Qf3 h4 25.Rg4 Kh8 26.Qe2 Rf5 27.Qe4 Nxf4 28.Rfxf4 Rxf4 29.Rxf4 Rg7 when Black is clearly better.

Black's move opens up a tactical opportunity for White that hides behind the smokescreen of an apparent blunder.

22.Bd2 Ng3

Forking White's Rook and Queen. (He should have abandoned the Knight with 22...Kh8, but then White would have the better game.)

23.Rf7+ Kh8 24.Rh7 checkmate

Monday, March 28, 2011

Notice that my fingers never leave my hand...

I just finished playing a Jerome Gambit game where my opponent responded to my every move quickly and decisively. He was zooming down one of the refutation lines that had given me worries in the past, and he was just about at the point where he would make me disappear  when something unexpected happened.

perrypawnpusher - NN
blitz, FICS, 2011

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


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


7.Qf5+ Kd6 8.f4 Qh4+

Wow! I half-expected 8...Nf3+ as I saw in "Vortex". That's merely one of many ways to smash the Jerome.

The text move is something that I most recently wrestled with last year in "Nice Kitty..." – how close will my opponent come to playing out the full refutation in this line?

9.g3 Nf3+

Closer...

10.Kf1

I've also played 10.Kd1 and entered what I call "the buyer's regret variation".


10...Qh3+

My first thought was: Hey, I've never seen this move before...

Then, Black resigned and I suddenly realized why.

(He was such a good sport about the oversight, I saw no reason to use his handle, but opted for "NN".)

Accelerated Instant Victory


I am not particularly a fan of the Accelerated Semi-Italian Jerome Gambit, but for those who play it, the following game should be a reminder that a false move like 5...Ke8 for Black can lead to another kind of Instant Victory.


Ghandy - Kwanza
blitz, FICS, 2011

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.Bxf7+


White does not wait for a Black Bishop to appear at c5, he sacrifices anyhow. Although the opening does not appear to have a name, it looks like an Accelerated Semi-Italian Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke8


Perhaps thinking, on reflex, that the King will be safer here. However, we will now see an ending similar to that presented in "Instant Victory" and "Instant Victory Redux".

6.Qh5+ Ke7

Black can throw in 6...g6 as in GFcrafty - Suigeneris, blitz, FICS, 2001, but after 7.Qxg6+ the result will be the same.

7.Qf7+

Also successful was 7.Ng6+ Kd6 8.Qd5 checkmate as in Dasistes - GeorgeVonGeorge, blitz, FICS, 2008.

However, 7.0-0 was not successful, as in EvashUcrushU - mrcain, FICS, 2009, which continued 7...Nxe5 (7...Qe8 was a bit better) 8.Qh4+ (White should have taken the draw by repetition with 8.Qxe5+ Kf7 8.Qd5+ etc.) g5 9.Qg3 d6 White resigned.

7...Kd6 8.Nc4+

Not quite as accurate was 8.Qd5+ but it was sufficient for the full point after 8...Ke7 9.Ng6+ Ke8 10.Nxh8 Nce7 (falling on his sword) 11.Qf7 checkmate in Esistes - SURPRISE, blitz, FICS, 2010.

8...Kc5 9.Qd5+ Kb4 10.c3+ Ka4 11.b3 checkmate


Today's game is the same as GFcrafty - tomamelheim, blitz, FICS, 2001

Casually

The Italian Four Knights Game is a pretty tame beast, and when White livens it up (actually, "deadens" it up might be more accurate in terms of his chances) with a couple of piece sacrifices, it can be hard for Black to develop a sense of urgency or to even take things other than casually.

perrypawnpusher - Aerandir
blitz, FICS, 2011

1.e4 e5 2.Nf3 Nf6 3.Nc3 Nc6 4.Bc4 Bc5



The Italian Four Knights Game.

5.Bxf7+

The Italian Four Knights Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.d4 Bb4


An interesting defense that seems, on the surface, to have a number of things going for it, although it reduces Black's game from "won" to "equal". The line was well-explored in "Coffee Break".

8.dxe5 Bxc3+ 9.bxc3 Nxe4

All according to short-sighted plan: bust up White's pawns and then gobble one. Black would keep the game even with 9...Re8 10.exf6 Rxe4+ 11.Be3 Qxf6.

10.Qd5+ Ke8 11.Qxe4 Qe7 12.0-0 d6



Black is not distressed: White's extra pawn is doubled, and there are enough open lines to trade off the heavy pieces and slide into the infamous Bishops-of-opposite-colors endgame where a draw can be found.

13.Bf4 dxe5 14.Rfe1 Bd7



This move, however, is a bit too casual.

15.Qxb7 Black resigned.

It's not just the b-pawn, or the e-pawn and c-pawn that will follow it in capture: Black's King will be too exposed after 15...Kf7 16.Rxe5 Qf6 17.Qxc7 for the second player to hope any more for a draw.

Cat-and-Mouse


Bill Wall plays a cat-and-mouse game with his opponent's King as it tries to escape to its hole in the wall er, castle-by-hand.


Wall - Hamilton
Chess.com, 2011

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5


The Italian Four Knights Game.

5.Bxf7+

The Italian Four Knights Jerome Gambit.

5...Kxf7 6.Qe2

An interesting idea. The Database has over 30 games by "hinders" at FICS with this move, winning over 50% of the time, in the years 2000-2002. 

6...Rf8

The theme of the game: Black would like to move his King to safer quarters. White does not allow this.

7.Qc4+ Ke8

Black's King is spooked. Otherwise he would have played the thematic 7...d5. After 8.Qxc5 Nxe4 9.Nxe4 dxe4 10.Nxe5+ Nxe5 11.Qxe5 Kg8 a lot of attacking pieces have been exchanged, and Black's pawn at e4 is remarkably resilient. White would be up a pawn, but it will be a while before it means anything – and there is always the notorious Bishops-of-opposite-colors endgame for Black to aim for.

8.Qxc5 d6 9.Qe3 Be6


White has an extra pawn and a safer King.

10.d3 Kf7 11.Ng5+

Meow!

11...Ke7 12.Bd2 Qd7 13.0-0 h6 14.Nxe6 Qxe6


It's the same story: development is even (maybe better for Black, if you count his King as developed), while White has an extra pawn. Open lines will show which monarch is safer.

15.f4 Ng4

Irresistible as ever.

16.Qg3 h5 17.h3 Nf6


Now Wall wraps things up.

18.fxe5 dxe5 19.Nd5+ Nxd5 20.exd5 Qxd5 21.Qxg7+ Kd6 22.Rxf8 Black resigned

Rope-A-Dope


The following game has a sense of strangeness about it.

It was as if my opponent were adopting a rope-a-dope strategy against me. It worked, up until the point when it didn't...



 
perrypawnpusher  - rsiemon
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 d6 9.Qe3 N8e7


10.f4

This is about as strong as 10.0-0 (which will come next move) or 10.d4 (which never quite arrives).

10...Bd7

To fight against White's e-pawn. Better, although looking anti-positional, was 10...c5.

11.0-0

The next time I play this line, I will opt for more center action with 11.f5 Ne5 12.d4 N5c6 13.Nc3 Kf7 and then 14.0-0 with a roughly even game.

11...Bc6 12.f5 Nf8



Come and get me!

My next move tries to do just that, but there is not a whole lot for White in either (slightly better) alternative: 13.Nc3 Nd7 14.d4 Nf6 15.e5 dxe5 16.dxe5 Nfd5 or 13.d4 Nd7 14.c4 Nf6 15.e5 dxe5 16.dxe5 Ng4

13.f6 gxf6 14.Rxf6 Ng8


Come and get me!

15.Rf1 Qe7 16.d3 Rd8

After the game Rybka 3 suggested 16...Qg7 17.Bd2 Nd7 18.Nc3 Ne7 19.Rf2 Rg8 20.Qe2 b5 21.Raf1 Ne5 as about even.

17.Qg3

Again, Rybka 3's post-mortem suggestion was 17.Nc3 Qg7 18.d4 Nf6 19.Qg5 Qxg5 20.Bxg5 Nxe4 21.Rae1 d5 22.Bf6 Rg8 23.Nxe4 dxe4 24.c4 Kd7 25.Bxd8 Kxd8 26.d5 Be8 27.Rxe4 when White has a Rook and two pawns to Black's two pieces.

17...Rd7

Time to castle-by-hand on the Queenside... Funny! 

18.Nc3 Qg7 19.Qh3 Kd8 20.Be3 Kc8


By this time in the "Rumble in the Jungle", George Foreman had largely worn himself out against Muhammad Ali and his rope-a-dope tactics.

21.Rf2 Kb8 22.Raf1 Rd8


Black finally drops his guard.

23.Rf7

Here, Black forfeited on time. After the necessary 23...Qg6 he would lose a Knight to 24.Rxf8.
