The Long and Winding Road

The following game takes its time getting where it's going. In fact, it probably could have taken even longer, if my opponent had not forseen the future and decided to stop travelling.

perrypawnpusher - VGxdys
blitz, FICS, 2011

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6


The Semi-Italian Opening.

4.O-O Bc5 5.Bxf7+


The Semi-Italian Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ Ng6 8.Qd5+

Interestingly, Rybka 3 (at a depth of 20 ply) sees this "nudge" as 1/2 pawn better than the immediate capture, 8.Qxc5.

8...Ke8 9.Qxc5 d6 10.Qe3 Nf6



A standard Semi-Italian Jerome Gambit position, although Black has also played 10...Qf6 in perrypawnpusher - saltos, blitz FICS 2009 (1-0, 28); 10...Ne5 in perrypawnpusher - Kotimatka, blitz FICS, 2009 (1-0, 21) and perrypawnpusher - Eferio, blitz, FICS, 2011 (1-0, 24); 10...Qe7 in perrypawnpusher - Macgregr, blitz, FICS, 2010 (1-0, 23); and 10...N8e7 in perrypawnpusher - apinheiro, blitz, FICS, 2010 (1-0, 59), perrypawnpusher - VGxdys, blitz, FICS, 2011 (1-0, 32) and perrypawnpusher - apinheiro, blitz, FICS, 2011 (1-0, 25).

11.f4

Or 11.d4 and then 12.f4 as in perrypawnpusher - KenWhitaker, blitz, FICS, 2010 (1-0, 27).

11...Kf8

Taking the King off of the dangerous e-file, if temporarily putting him on the dangerous f-file. Black's plan is to castle-by-hand, with the King ending up on h7. Instead a center strike with 11...Qe7 12.d3 d5 occurred in perrypawnpusher - LeifPetersen, blitz, FICS, 2010 (1-0, 30).

12.f5 Ne5 13.d4 Nc4



It was probably safer to play 13...Nf7, but who can resist harassing the Queen?

14.Qd3 b5

Oddly similar to our earlier game, referred to above.

15.b3 Nb6 16.Nc3 Kg8 17.Qxb5 a6 18.Qe2 Kh7


White has grabbed a Queenside pawn while Black has castled-by-hand on the Kingside. The game is about even.

19.e5 dxe5 20.dxe5 Nfd5 21.Bb2

Good enough, although with White's forces focusing on the f6 square, 21.Ne4 would have been even better.

21...Re8 22.Rad1 Qg5



This was Black's idea, attacking White's King.

25.Rd2 a5 26.Qf2 Ba6 27.Rfd1 Rad8 28.Rxd8 Rxd8 29.Rxd8 Qxd8


30.Qd4 Qg5 31.e6 Bb7 32.Qf2 Be4 33.f6 gxf6 34.Bxf6 Qc1+


The game has taken on some of the annoying aspects of the typical Jerome Gambit Bishops-of-opposite-colors endgame. Still, I was willing to exchange Queens and try my luck. Too, exchanging Queens was Black's best chance.

35.Qf1 Qe3+ 36.Kh1 Bxc2 37.e7 Bd3

A slip, which should have been punished by 38.e8/Q, winning the Bishop.

38.Qg1 Qe6 39.Bh4 Qf7



40.Qe1 Bb5 41.Qe4+ Kg7

Another slip: White can now check the King and win the Bishop.

My opponent seems to have been a bit too comfortable with his assessment of the endgame as drawish. That made two of us.

42.Qg4+ Kh7 43.Qe4+ Kg8 44.h3


A small idea, but a useful one. With the back-rank checkmate prevented, my Queen can wander more successfully, not just limiting herself to offeres to exchange or checks on the enemy King.

44...Bd7 45.Kh2 Qe8

White's e-pawn is effectively blockaded, his Queenside pawns will not produce a passer on their own, and creating one on the Kingside will expose the White King to plenty of attacks. A win for for me, if it is there, is a long way down the road.

46.Qc4+ Kh7 47.Qxc7 Black resigned


With my King safe, however, my pawns do not have to do it on their own. The Queen will soon pick off Black's a-pawn, and then White's Queenside pawns will begin to advance and assert themselves.

My opponent decided that there was no need to let things go that far.

23.Nxd5 Nxd5 24.Rxd5 Bb7

The Killing Blow (Part 2)

Yesterday (see "The Killing Blow (Part 1)") we saw how well-timed carelessness can turn a simple walk in the Semi-Italian Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.0-0 Bc5 5.Bxf7+) park into a nightmare.

Picking up the action in perrypawnpusher - KenWhitaker, blitz 6 12, FICS, 2010:


17...b6

KenWhitaker had a wild idea that he wanted to add to my misery.

18.Bxh6


This is the move that I had been dreaming up. It doesn't save White, but it complicates things enough to allow for an escape.

18...Ba6


Winning the exchange.

Still, Black should have stayed with the program: 18...gxh6 19.Qg3+ Ng4 20.hxg4 Bb7 21.Qd3 Qg5 22.g3 Ng6 when White's two extra pawns do not balance out Black's extra piece. 





analysis diagram






19.Qg3


There is no time to save the Rook on f1 – and no need.

19...Nh5


Black's other defensive try was 19...Qe7. White can scramble to keep things busy: 20.Rf2 Nh7 21.Nd5 Qd7 22.Qxh4 gxh6 23.Rf6 and White is holding his own in the mess.





analysis diagram






20.Qg4 Bxf1 21.Rxf1


I imagine about now my opponent was thinking, even as his clock ticked on: What does a defender have to do to win this game?? White is down a Rook! What are my Knights doing over there? Can't I get rid of that annoying Bishop?

21...Re6


Oh, no!!

A Rook move was the right idea, but not that one. 

After 21...Rf8 22.Rxf8+ Qxf8 23.Qxh4 Qf6 24.Qxf6 Nxf6 25.Bg5 White's Knight and two pawns would be a match for Black's Rook.





analysis diagram







22.Qxe6+


22...Kh7 23.Be3 Nf6 24.Bg5 Ng6 25.Bxf6 gxf6


White's advantage is much greater than a few pawns.

26.Rxf6 Nf8

The final let down.

27.Qf7+ Black resigned


Who was it that said "Good luck is better than a license to steal"?

The Killing Blow (Part I)

It is annoying to play a familiar opening line – only to slip and end up in grave danger. There is little margin for error in any variation of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+).

While I awaited the killing blow, I consoled myself with something IM Gary Lane wrote in one of his "Opening Lanes" columns at ChessCafe:
It is always fun to find an opening which can cause confusion with something unusual. The psychological impact can be huge and the hapless opponent is obliged to consume large amounts of time coping with the new situation.
ICCF Senior IM Tim Harding was equally philosophical in one of his "The Kibitzer" columns, also at ChessCafe
One of Black's (psychological) problems is that... looks so obviously unsound that it is hard to decide which "refutation" to adopt. Psychologically, opponents often don't play in a stable and rational way when they believe their game is won from a very early stage and they tend to underestimate their opponents
Lane and Harding were not writing specifically about the Jerome Gambit, but they could have been.

perrypawnpusher  - KenWhitaker
blitz 6 12, FICS, 2010


1.e4 e5 2.Nf3 Nc6 3.Bc4 h6


The Semi-Italian Opening.

4.0-0 Bc5 5.Bxf7+


The Semi-Italian Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.Qh5+ Ng6


Counting this game, I have had this position 10 times, and scored 9 1/2 points. I was feeling comfortable, while my opponent was already eating into his time.

8.Qd5+

It is, of course, possible to capture the Bishop directly with 8.Qxc5, (see RomanDurdis - ifufocop, FICS, 2005, abhailey - cumelen,mm Open Fast #1, net-chess.com, 2008 and Black Puma - TWODOGS, JGTourney4, ChessWorld, 2009) but I prefer the "nudge" to give my opponents more to think about.

11...Kf7 12.f4 Re8 13.Nc3 Kg8


Here we have a familiar type of position: Black has castled-by-hand and brought his Rook to the e-file; while White has his "Jerome pawns" ready to advance.

I've taken about a minute of thinking time; my opponent, a good bit more.

It should be like taking a stroll in my own back yard...

14.f5 Ne7

15.h3

Preparing for g2-g4, but without much thought. Later, Rybka pointed out the right way to accomplish this: 15.Qg3 Kh7 16.Qh4 Rf8 17.Bg5 Qd7 18.Rad1 Qc6 19.Bxf6 Rxf6 20.g4




analysis diagram







Black would still have an edge, but White would have his thematic pawn play.

15...Nxf5


Ouch! The e-pawn is pinned... Even worse would have been: 15...d5, when White would have to give up the exchange, either by 16.e5 Nxf5 17.Rxf5 Bxf5 or (according to Rybka) 16.Qg3 dxe4 17.Bxh6 Qxd4+ 18.Kh1 Nh5 19.Qg5 Nxf5 20.Rxf5 Bxf5 21.Qxh5 Rf8 22.Bf4.

16.Qd3 Nh4


At this point I started using up thinking time. I found a way to complicate things, and made my move. 

17.Bf4


Oh, no! Where did that come from?? That wasn't what I was thinking about at all...
