Dealing with Harassment

I have read that Grandmasters can look at a complicated position and almost immediately, without apparent analysis or evaluation, decide that a certain piece "must" go to a particular square. How different that is from my own experience...

perrypawnpusher - louarn
blitz, FICS, 2010

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5

Earlier this year we had played a couple of Semi-Italian Four Knights Jerome Gambit games that I had won in 21 and 49 moves.

4.Bxf7+


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


7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 N8e7


Planning for play on the f-file, especially targeting the square f5, which seems to be a magnet for "Jerome pawns".

10.0-0 Rf8

An interesting alternative is 10...d5, seen in perrypawnpusher - OverwiseMan, blitz, FICS, 2010 (1-0, 27).

11.f4

Or 11.d4, as Louis Morin (mrjoker) has played successfully in a couple of games, guest6567 - guest4702, ICC, 2004 (1-0, 26) and mrjoker - tomnoah, ICC, 2008.


11...Bd7


With an eye toward putting the Bishop on the a8-h1 diagonal. Both 11...Nc6, as in perrypawnpusher - taman, blitz, FICS, 2010 (1-0, 35), and 11...c6 as in perrypawnpusher - Kovrad, blitz, FICS, 2010 (1-0, 16) were also playable. 

 12.f5 Ne5 13.d4 Ng4


As always, retreating to c6 was better, but harassing the Queen is irresistible. A quick peek at the New Year's Database shows that I have over 45 games with a Queen at e3 being attacked by a Knight at g4!

You would think that by now I would have come up with the proper response for White.

14.Qg5

An interesting idea, but I had forgotten that I had tried something similar in one of my games against MRBarupal and my pawn at e4 (as well as the square itself) proved weak. It should not be surprising, therefore, that Rybka prefers 14.Qe2 (although it sees the game as even after my move).

14...Nf6 15.e5

Rushing forward into trouble. First: 15.Nc3

15...dxe5 16.dxe5 Ne4


There's that weak e4 square again.

17.Qxg7

The position may look dangerous for Black at first glance, but White has two pieces attacking five pieces (six, if you count the enemy King) and the pair of advanced "Jerome pawns" doesn't make up the difference.

 17...Nxf5 18.Qxh7 Qe7


Exchanging Queens takes the heat off of Black's King and preserves his advantage, although 18...Be6 was even stronger.

19.Qxe7+ Kxe7 20.Nc3 Nxc3 21.bxc3 Nh4


Hoping to exchange another piece, bringing the game closer to a won endgame, as White's pawns will be no match for Black's extra piece.

However, this was just the kind of slip that I was hoping for as it allows me to reverse my fortunes.

22.Ba3+ Ke6 23.Rxf8 Rxf8 24.Bxf8 Kxe5


Up the exchange and two pawns, White now has the winning chances.

25.Bg7+ Kd5 26.Rd1+ Kc6 27.Kf2 Nf5 28.Bd4 b5

I think this must have been a mouse-slip.

29.Bxa7 Kb7

Allowing the exchange of Bishops only hastens the end.

30.Bd4

See above. 

30...Ka6 31.Be5 Be6 32.Bxc7 Bxa2 33.Ra1 Kb7 34.Rxa2 Kxc7


35.g4 Nd6 36.Kf3 Nc4 37.g5 Ne5+ 38.Kf4 Ng6+ 39.Kf5 Ne7+ 40.Kf6 Nd5+ 41.Kf7 Nxc3 42.g6 Ne4 43.g7 Nd6+ 44.Kg6 Black resigned

The Eeeeeeeeeeeeeee File Again

Again disaster arrives down the e-file. Even if you are playing against a refuted opening like the Jerome Gambit, it is not a good idea to keep your King and Queen too long on an open file.

perrypawnpusher - OverwiseMan
blitz, FICS, 2010

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


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


An earlier game with my opponent continued: 6...Ke6 7.Qf5+ Kd6 8.f4 Qe8 9.fxe5+ Kc6 10.c3 Ne7 11.Qg5 g6 12.d4 h6 13.Qg3 Bb6 14.d5+ Kb5 15.Na3+ Ka6 16.Qd3+ Ka5 17.Qb5 checkmate, perrypawnpusher - OverwiseMan, blitz, FICS, 2010.

7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 N8e7


More often seen is 9...Nf6. The text move can be a prelude to play along the f-file.

10.0-0

Or 10.f4 Rf8 11.0-0 Nc6 12.f5 Nge5 13.d4 Ng4 14.Qg3 h5 15.Be3 Nxe3 16.Qxe3 Qf6 17.c3 g6 18.Nd2 g5 19.e5 dxe5 20.dxe5 Qxe5 21.Qxe5+ Nxe5 22.Rae1 Kf7 23.Rxe5 Kf6 24.Re2 Bd7 25.Ne4+ Kg7 26.f6+ Kg6 27.Rfe1 h4 28.c4 g4 29.Rf2 Rae8 30.Rfe2 Bc6 31.Nd2 Rd8 32.Ne4 h3 33.gxh3 gxh3 34.Kf2 Rde8 35.Kg3 Black resigned, perrypawnpusher - taman, blitz, FICS, 2010.

10...d5

A good idea.

Earlier I saw 10...Be6 11.f4 d5 12.f5 d4 13.Qg3 Bc4 14.d3 Bxd3 15.cxd3 Nf8 16.Qxg7 Rg8 17.Qe5 c5 18.f6 Nfg6 19.f7+ Kf8 20.Bh6+ Rg7 21.Qxg7 checkmate, perrypawnpusher - perama, blitz, FICS; and 

10...Rf8 11.f4 c6 12.f5 Ne5 13.d4 Ng4 14.Qg3 Nf6 15.Qxg7 Rg8 16.Qxf6 Black resigned, perrypawnpusher - Kovrad, blitz, FICS, 2010.

11.exd5

After the game Rybka preferred 11.d3 followed by f2-f4.

11...Qxd5 12.Nc3 Qe5


The first confrontation on the e-file. I wasn't happy with the idea of exchanging Queens, but I couldn't think of anything better.

13.d4 Qe6

Puzzling: I thought he would have been happy with 13...Qxe3. Maybe he was thinking, If White wants to exchange Queens, then I don't want to.

14.Qg3 c6


15.Bg5 Nf5 16.Qd3 h6

Mistakenly assuming that White will move his Bishop. But, instead, there is the eeeeeeee-file!

17.Rae1 Ne5

Bad things are happening on the e-file, and this doesn't help. "Best" was 17...Kf7. 

18.Rxe5 hxg5 19.Rxe6+

Sufficient, but 19.Qxf5 was stronger.

19...Bxe6 20.Re1 Rd8

And White finishes up.

21.Rxe6+ Kf7 22.Qxf5+ Kg8 23.Qxg5 Rxd4 24.Re8+ Kf7 25.Rxh8 Ke6 26.Re8+ Kd6 27.Qe7 checkmate

Why must he lose to this idiot?

Not every chess player wakes up and says to himself (or herself) "I think I'll destroy a Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) today!" In fact, not many chess players even know what the Jerome Gambit is – so, it can be a puzzlement to not only be playing against it, but to find yourself losing against it...

perrypawnpusher  - Kovrad
blitz, FICS, 2010

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


In our first attempt at a game, my opponent disconnected here, and FICS aborted the game. This was probably all beyond Kovrad's control, as he has this explanatory message posted at FICS "Please note that at times I can have a very bad internet connection. Therefore don't be surprised when I 'disconnect'. I will always try to come back and finish the game (though sometimes it's impossible). If my position is lost I will resign. Sorry for inconvenience."

Fair enough.

So I signed on again and challenged Kovrad again.

4...Kxf7 5.Nxe5+ Nxe5

I found a couple of other games with my opponent defending against the Jerome Gambit:

5.d4 Bxd4 6.Ng5+ Ke8 7.c3 h6 8.Qh5+ g6 9.Qxg6+ Black resigned, DragonTail - Kovrad, FICS, 2009; and 
5.0–0 d6 6.c3 Ke8 7.d4 exd4 8.cxd4 Bb6 9.Ng5 Bxd4 10.Qh5+ g6 11.Qf3 Bf6 12.h4 Ne5 13.Qb3 Qe7 14.Nc3 c6 15.Bf4 h6 16.Bxe5 hxg5 17.Bxf6 Qxf6 18.hxg5 Qxg5 19.e5 Qh4 20.exd6 Qh1 checkmate, sebya - Kovrad, FICS, 2008.

6.Qh5+ Ng6


7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 N8e7


Not as popular as 9...Nf6, but very clear: Black wants play on the f-file.

10.0-0 Rf8

Provocative was 10...Be6, as in 11.f4 d5 12.f5 d4 13.Qg3 Bc4 14.d3 Bxd3 15.cxd3 Nf8 16.Qxg7 Rg8 17.Qe5 c5 18.f6 Nfg6 19.f7+ Kf8 20.Bh6+ Rg7 21.Qxg7 checkmate, perrypawnpusher - perama, blitz, FICS, 2010.

11.f4 c6


Or 11...Nc6 as in perrypawnpusher - taman, blitz, FICS, 2010 (1–0, 35).

12.f5 Ne5 13.d4 Ng4 14.Qg3


 14...Nf6 15.Qxg7


Despite appearances, everything is under control for Black. He can play the prepared 15...d5, and after 16.exd5 Qxd5 he is prepared for 17.Bg5 which he can meet with 17...Nxf5 18.Rxf5 Bxf5 19.Bxf6 Qf7 20.Qxf7+ Kxf7 21.Be5 Bxc2 when Black has an edge.

Instead, he played a reflexive move – and then resigned in apparent disappointment.

15...Rg8 16.Qxf6 Black resigned


Black is down three pawns, and the open lined to his King and the white "Jerome pawns" will cause more grief.

I am sure Kovrad was much too much a gentleman to exclaim, as Nimzowitsch once did, "Why must I lose to this idiot??"
