Nothing Happened

In my second post-break game, pretty much nothing happened. My opponent decided to take the game into a pawn-down Queenless middle game where, presumably, he thought he would be okay. I decided to take the game into a pawn-up endgame, where I thought I would be okay...

perrypawnpusher - Edvardinho
blitz, FICS, 2010

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


Standard Jerome Gambit.

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5


Now 7...d6 would be Blackburne's Defense, and 7...Qe2 would be Whistler's Defense.

7...Bxf2+

There are 55 examples of this "calming variation" in the New Year's Database, with White scoring 71%. See "Jerome Gambit Strikes in Denmark!"

8.Kxf2 Qf6+ 9.Qxf6+ Nxf6


10.Nc3 Rf8 11.Rf1 Kg7 12.Kg1 d6 13.d3


13...Bg4 14.Bg5 Nd7 15.Rxf8 Rxf8 16.Rf1 Rxf1+ 17.Kxf1


17...Ne5 18.Kf2 Be6 19.h3 h6 20.Be3 c5 21.b3 a6 22.a4 g5


The pawn formations suggest that this will not be a prosaic Bishops-of-opposite-colors endgame.

23.Nd5 Bxd5 24.exd5 Kf6 25.d4 Nd7 26.dxc5 Nxc5 27.Bxc5 dxc5 28.c4 Ke5


It's only one extra pawn, but it will be enough.

29.Ke3 b5 30.axb5 axb5 31.g3 bxc4 32.bxc4 h5 33.g4 h4


34.Kd3 Kd6 35.Ke4 Kc7 36.Kf5 Kd6 37.Kxg5 Ke5 38.Kxh4 Kd4


39.d6 Kxc4 40.d7 Kc3 41.d8Q c4 42.Qd1 Black resigned


It is hard to tell from this game if I have made any progress. The danger is that in such situations I tend to allow the game to "play itself" and that leads to overlooking important tactics for both players.

Starting Over

This is my first post-break game (see "Busted!"), and except for a missed shot on move 16, it looks like the rest has helped my game. Time will tell.

 
perrypawnpusher  - ozypawnstar
blitz, FICS, 2010

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


The Blackburne Shilling Gambit.

4.Bxf7+

The Blackburne Shilling Jerome Gambit.

4...Kxf7 5.Nxe5+

Oddly, the online FICS games database has yeabro- ozypawnstar, FICS, 2010, which continued 5.Ng5+ Qxg5 listed as a win for White...

5...Ke6

Taking up the challenge.

Previously ozypawnstar played 5...Ke8: 6.Qh5+ g6 7.Qg4 Nf6 8.Qf4 Nxc2+ 9.Ke2 Nxa1 10.Nc3 Bd6 11.Nd5 Bxe5 12.Qxe5+ Kf7 13.Nxf6 Qxf6 14.Qxc7 Re8 15.d3 Kg8 16.Qc4+ Kg7 17.Be3 d6 18.d4 Rxe4 19.Rxa1 Be6 20.Qc7+ Kh8 21.Qxb7 Rf8 22.Qxe4 Bc4+ 23.Ke1 d5 24.Qc2 a6 25.b3 Bb5 26.a4 Bd7 27.b4 Qh4 28.h3 Re8 29.b5 Qxd4 30.Rd1 Qb4+ 31.Kf1 axb5 32.Rxd5 Rc8 33.Bd4+ Kg8 34.Qd2 Qc4+ 35.Kg1 Qxd5 36.axb5 Bxb5 37.Qh6 Qxd4 38.g3 Bc6 White resiged, GuyEtienne - ozypawnstar, FICS, 2008.

6.c3

Best.

My opponent has also faced: 6.Qh5 Nf6 7.Nf7 Qe7 8.Qh3+ Kxf7 9.0-0 Nxc2 10.Qb3+ Qe6 11.Qxc2 Qxe4 12.Qxc7 Qc6 13.Qf4 Bd6 14.Qd4 b6 15.Nc3 Bb7 16.f3 Rhe8 17.d3 Be5 18.Qh4 Kg8 19.Bg5 a6 20.Rac1 Bd4+ 21.Kh1 h6 22.Ne2 Qd6 23.Bf4 Qe6 24.Nxd4 Qxa2 25.Nf5 Qxb2 26.Nd6 Re2 27.Nxb7 Rxg2 28.Be5 Qxe5 29.Kxg2 Re8 30.Rce1 Qb2+ 31.Kg1 Rf8 32.Qc4+ Kh8 33.Nd6 b5 34.Nf7+ Kh7 35.Ng5+ hxg5 36.Qc5 Rg8 37.Qxg5 Rf8 38.Kh1 Qd4 39.Rg1 Rf7 40.Rg3 Qxd3 41.Rh3+ Kg8 42.Qh4 Qf5 43.Qh8 checkmate, fmarius - ozypawnstar, FICS, 2010.

6...d6

Varying from the main line, which features a King's walk and which did not serve him well in the past: 6...Kxe5 7.cxd4+ Kxe4 8.0-0 Kxd4 9.d3 d5 10.Qh5 Nf6 11.Be3+ Kxd3 12.Rd1+ Kc2 13.Na3+ Bxa3 14.Rac1+ Kxb2 15.Qe5+ Kxa2 16.Rd2+ Kb3 17.Qc3+ Ka4 18.Rd4+ Kb5 19.Rb1+ Bb4 20.Rdxb4+ Ka5 21.Qa3 checkmate, icefive - ozypawnstar, FICS, 2009.

7.cxd4 dxe5 8.d5+

I used up a third of my thinking time on this move, only to learn after the game that Rybka preferred 8.dxe5, which I had rejected because of the cramping response 8...Qd3.

My goal in this (and later) games was to use more time on early critical positions than I usually allowed myself, with the hope that finding the right move or plan would shorten the game (with a win) and the time wouldn't be needed later. So even though I didn't find the "best" move, what I understood about the position was helpful and worth the time.

8...Kd6

The King was safer on f7.

9.d4

Open the center, develop pieces.

9...Qf6

Black reverses moves. He should have played 9...exd4 10.Qxd4 Qf6, although White would still be better.

10.dxe5+

Missing the great move 10.f4 (I had a similar plan in mind), which  floods the center with "Jerome pawns." Then 10...Ke7 11.dxe5 looks very uncomfortable for Black.

10...Qxe5 11.Nc3 Nf6 12.f4 Qe8


13.e5+ Kd7 14.0-0 Ng8



15.Be3

I was very happy with this patient move. It was not time to fling pawns further forward.

15...Bb4

This should cost a piece.

16.Qd4

Leading to an advantage, but 16.Qa4+ probably would have lead to my opponent's resignation. (Note to self: once you find a good move, sit on your hands...etc.)

16...Bxc3 17.bxc3 Ne7


18.e6+ Kd8 19.f5 Qb5 20.c4 Qb4 21.f6


This works, but 21.Qxg7 was better, as after 21...Rg8 22.Qf7 the White f-pawn advances with greater impact.

21...Nxd5

An oversight. I think my opponent saw that the c-pawn was pinned, but a pawn capture wasn't my only possible response.

22.Qxd5+ Qd6 23.fxg7 Rg8 24.Qxd6+


I saw a win and went for it, missing the quicker 24.Rf8+ Ke7 25.Bg5 checkmate. 

24...cxd6 25.Rf8+ Ke7 26.Rxg8 Kxe6 27.Rf8 b6 28.g8Q+ Ke7 29.Qf7 checkmate

Et Tu, GriffySr?

I've reported elsewhere on the phenomenal success that GriffyJr and GriffySr at FICS have had with and against the Jerome family of openings – and as clones of the chess-playing computer program Crafty, that is not a surprise.

Still, it is a bit unsettling to see one of them recently manhandle a Jerome Gambiteer in a critical theoretical line.

NIZAM - GriffySr
standard, FICS, 2010

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


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

Computers are far less afraid of this line than humans.

7.f4 d6

The frustrating line that computers love. There's no use playing the Jerome Gambit against a computer unless (among other things) you have a plan on how to attack this.

8.Qf5+

NIZAM launches his Queen against the defense. "Book" is 8.fxe5.

8...Ke7 9.Qg5+ Ke8 10.Qxg7


A human blitz player, seeing two pieces attacked and the enemy Queen so close to his King, might quail; but not a feeling-less computer. 

10...Qh4+ 11.g3

There was no joy in the "better" 11.Qg3 Qxg3+ 12.hxg3.

11...Nf3+ 12.Ke2 Nd4+ 13.Kd1



Allowing the finish.

13...Bg4+ 14.Ke1 Nxc2+ 15.Kf1 Qh3 checkmate


"I come to bury Caesar, not to praise him..."

Challenges




Although we in the Jerome Gambit Gemeinde are always improving our openings, there are those who defend who are doing the same. That can lead to some uncomfortable challenges.


aymmd - MOMLASAM
standard, FICS, 2010

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.0-0 Nf6 5.Bxf7+


Not quite the Italian Four Knights Jerome Gambit.

I have three recent games by aymmd in the updated New Year's Database. It' looks like he's just taken up the opening. As he's rated well above me, and is playing the Jerome at a standard time control, not blitz, his games should be interesting.

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



7...Bxd4 8.Qxd4 d6 9.Nc3 Re8


10.Bg5 h6

Not a surprise: besides exchanging pieces, White can keep the tension with 11.Bh4 or try the interesting 11.f4.

11.Bxf6 Qxf6 12.f4


Aggressive (the White Rook on the same file as Black's Queen and King) but overlooking the same kind of tactic that I did in my game with Jantra. (Therefore 12.Rad1 was to be considered.)

12...Nf3+ 13.Rxf3 Qxd4+ 14.Kh1 Kg8 15.f5 Bd7 16.Rd1 Qe5 17.Rd5 Qf6 18.Rd1 Bc6 19.Rf4 g5 White resigned

Jerome Gambit, Over-the-Board

Pete Banks ("blackburne") is known to readers of this blog. His Jerome Gambit games have appeared in Gary Lane's ChessCafe column and in the IM's The Greatest Ever Chess Tricks and Traps. Here is his latest over-the-board excursion.

Banks,P - Dunne,D
Worcestershire v Derbyshire, U-140, 2010[Notes by Pete Banks]

My opponent didn't turn up. Because his name was on the match sheet, and I made my move, I thought that I just had to wait for his flag to fall. Unfortunately the Midland Counties have a rule that allows substitutions.

1.e4 e5 2.Nf3 Nc6 3.Bc4

I might as well see if I can play it.

3...Bc5

Here we go!

4.Bxf7+

One piece sacced.

4...Kxf7 5.Nxe5+ Nxe5

Two pieces sacced after 5 moves! Now I've got a won game. (In my dreams)

6.Qh5+ Kf8 7.Qxe5

One piece back!

7...d6 8.Qg3 Qe7 9.Nc3 Nf6 10.d3 h6


I've used 4 minutes and he's used 35 (including the time waiting for his teammate).

11.Be3 Bb6 12.0-0-0

Starting to pile up my army against his exposed King.

12...c6 13.f4

I believe my friend Rick calls these (e4 and f4) the 'Jerome pawns'.

13...Bxe3+ 14.Qxe3 b5 15.h3

I've been worried about N or B g4 for some time. I'm still two pawns for a piece, but the pawns could be strong.

15...b4

I'm going to more or less ignore his attack, because I think mine is better.

16.Ne2

In an ideal world, this will go to f4 and g6 giving a family fork.

16...c5

Still no real threat that I can see.

17.f5

Whereas this stops g5, cuts off his white-squared bishop, and supports the N going to g6.

17...Bb7 18.Nf4 Qf7


That stops my multiple fork, but I still win the exchange. He hasn't got time for Qxa2 if he wants to win the N.

19.Ng6+ Kg8 20.Nxh8 Kxh8 21.b3


I've now got R + 2P versus B+N. Advantage me I think.

21...a5 22.g4 a4

I still don't think there's anything to fear if I'm careful.

23.Qg3

This hits d6, but is really so I can move h4 without allowing Nxg4.

23...axb3 24.axb3


If his Q could get across to the a-file quickly, there might be cause for concern.

24...Qd7 25.h4 d5 26.e5


I thought about taking the d-pawn, but the passed pawn seemed better.

26...Nh7 27.Qf4

This is so I can play g5 without the Q taking my f-pawn. In this game my Q spends most of its time supporting pawns.

27...c4 28.dxc4 Ra1+


I have to be a bit careful now.

29.Kb2

If 29.Kd2, dxc4+ would be dangerous.

29...Rxd1 30.Rxd1 Bc6 31.cxd5

If he takes, the B is pinned, and he will lose it.

31...Nf8


I'm not sure what that was for, but I supppose there's not much choice.

32.Qxb4 Qd8

Nice combination to finish it.

33.dxc6 Qxd1 34.Qxf8+ Kh7


The only thing to worry about now is a perpetual check. The next move stops that.

35.Qd6 Qxg4

At this stage, Black's clock fell, but my next move would be Qg6 check which definitely finishes it. 



Modern over-the-board (as opposed to via the Internet) Jerome Gambit games are hard to come by. Does anyone else play the Jerome Gambit "in real life"? - Rick

Theoretical



The Jerome Gambit and its relations are fun "just do it!" openings, but over time they have developed their own "book" and sometimes a line, as the one discussed below, can become "theoretical".

MCMLXXXIII - TheProducer
blitz, FICS, 2010

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


The Blackburne Shilling Gambit.

4.Bxf7+

The Blackburne Shilling Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke8 6.Qh5+ g6


This position was reached in the game discussed yesterday (see "Really? Really.") and in 824 other games in the New Year's Database. White scored 60%.

7.Nxg6 Nf6

Not Black's best response (he should take the Knight), but it is enough to complicate the game.

8.Qe5+ Be7


Again, not the best, but, again, plenty messy. Black should try 8...Ne6 9.Nxh8 Bg7 as in perrypawnpusher - xenoglot, blitz, FICS, 2010 (1-0, 37).

White now has several options, only one of which leads to advantage. A little familiarity with the first moves of this opening can save a lot of calculation time and headaches later.

9.Nxh8

Tempting. However, the best chances came with 9.Nxe7, e.g. 9...Nxc2+ 10.Kd1 Ne3+ (or 10...Qxe7 11.Qxe7+ Kxe7 12.Kxc2) 11.dxe3 Qxe7 12.Qxe7+ Kxe7 13.f3 when White is up 2 pawns. 




analysis diagram








9...Nxc2+ 10.Kd1


10...Nxa1

This may be easy to work out with a longer time to think about it, but in blitz it is not as simple. See perrypawnpusher - lourotors, blitz, FICS, 2009 (0-1,37).

Kicking the White Queen with 10...d6 before capturing the Rook was a bit stronger, but in either case Black is better.

11.Nc3

Ignoring the Black Knight in the corner and working on development.

11...Ng4


Half of the moves in this game have been made by the Knights. Look at them!

Sadly, this move ends the game for Black. (Kicking the enemy Queen was a job for the d-pawn.)

12.Qh5+ Kf8 13.Qf7 checkmate
