Pathbreaking

Exploring an opening variation has its excitements and its drawbacks. Often it is best, once the end of the trail is reached, to reflect on the path travelled in case you go that way again.


AMITAF - aditikalpesh
blitz, FICS, 2011

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


The Blackburne Shilling Gambit.

4.Bxf7+

The Blackburne Shilling Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke6 6.f4


Common, but perhaps not best. This move allows Black chances that he does not take advantage of in this game.

6...Bd6

An odd sideline that puts Black at great risk. He needed to play 6...Qh4+ 7.g3 Qh3 with possibilities of infiltrating on the Kingside.

7.c3

Solid.

Next time White can come armed with 7.Qg4+ Kf6 (or 7...Ke7, jamci - tpg, FICS, 2009 [1-0, 26]; Handlangari - PlatinumKnight, FICS, 2007 [1-0, 9] and bushytail - PlatinumKnight, FICS, 2009 [1-0, 9]; or 7...Nf5 8.Qxf5+ Cyberkid - PlatinumKnight, FICS, 2009 [1-0, 8]) 8.Qg5+ wayaut - tomcatx, FICS, 2010 [1-0, 8] and Pandolfl - screaminghead, FICS, 2005 [1-0, 15]

7...Nc6

Lost.

Better: 7...Bxe5 while he has the chance. (Hint: White's best response would be 8.0-0, and he would be worse.)

8.d4


Again, the short cut next time would be 8.Qb3+ Ke7 9.Qf7 checkmate 

8...Nb8

Danger.

Again, 8...Bxe5 was the choice, with White only slightly better.

9.f5+

This leads to White's advantage. 

So, too, would 9.Qb3+ Kf6 10.Qf7 checkmate. 

9...Ke7 10.Bg5+ Nf6


The brutal pin on the Black Knight at f6 and the possibility of forking the Knight and Bishop with a pawn (once White's Knight is out of the way after 11.Ng4) give White a clear advantage.

11.Nd2 h6

Certainly Black should have tried to remedy the ills mentioned above with 11...Kf8 12.Nd3 Be7 13.e5 h6 14.Bh4 Nd5 15.Bxe7+ Qxe7 16.Qf3 Qf7 17.0-0 Nc6 18.Rae1 Kg8, although White would still be for choice.

Now the wilderness swallows him up.

12.Ng6+ Kf7 13.Qb3+


13...Ke8 14.Nxh8 hxg5 15.Qf7 checkmate

A Dubious Move

Recently I found the April/May 1983 issue of CHESS 'n stuff which contains the very first chess story that I had ever had published. It was fun to read through it again, although it made me groan as much as when I wrote it.
A Dubious Move

The Grandmaster had played the move. The Master, as his second, had recommended it. The Patzer, in a blaze of glory, had invented it.

It had cost them the World Championship.

Each now faced a very certain future in a country that tolerated no failure: the firing squad.

The Grandmaster eyed his executioners with ill-concealed contempt. As they raised their rifles, his eyes flew to the snow-covered mountains, and he bellowed "Avalanche!"

The troops scattered in disarray. When some thought to look back, they saw nothing save a set of new foot prints disappearing into the deep woods. The GM was gone.

The Master, in turn, took his place. No sooner had the recovered men shouldered their weapons than they heard the ringing, fear-laden phrase, "Earthquake!"

The ranks did not hold. As they returned in their embarassment, the soldiers noted a new set of treacks, and one less pawnpusher.

It was the Patzer's turn, but he was prepared. At the appointed time he confidently gaped at the forest, gesticulated wildly in its direction, and conjured up his own natural disaster.

"Fire!"

That was the first thing that anyone got right all day.

Dizziness Due to Success

Alexander Kotov, in his classic Think Like A Grandmaster, wrote about players who were

over-confident, complacent in their recognition of the fact that they had a marked advantage, and so their vigilance was blunted.
We call this widespread complacency when the win is near 'Dizziness due to success' .
perrypawnpusher - bnxr
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 10.O-O Kf7


Black returns the tempo that I spent on "the nudge" (see "Nudge 2.0")

11.f4 Re8 12.f5 Rxe4

While analyzing my game against stcamillis (see "Stand up! Fight back!") where I had played 12.d3, I had realized that 12.f5 was playable – in fact, it had been played as early as Vazquez - Carrington, Mexico, 2nd match, 1876, because the immediate threat against the pawn at e4 was an illusion.

That my opponent grabbed the pawn (his plan from move 10) is one more example of the negative "halo effect" that surrounds the Jerome Gambit: If White blunders so badly in the opening, he is going to blunder throughout the game. So any move that appears bad [like 12.f5], must be bad.

13.fxg6+ hxg6

An unfortunate reflex action. Black needed to play 13...Kg8, when 14.gxh7+ Kh8 15.Qd3 would have left White with a pawn advantage.

14.Qxe4

14...Bf5 15.Rxf5

The position looked messy after 15.Qxb7 Bxc2, so I decided to return a bit of my extra material (Rook for Knight + pawn) to reach a quieter position.


15...gxf5 16.Qxf5 Qe7 17.Qf1


This borders on anxiety, however. Simply 17.Nc3 was fine.

17...Rh8 18.d3 Qe5 19.Nc3

Up  a piece, a little bit of development – what could go wrong?

19...Qxh2+

Well, that's annoying.

The game would have been much simpler after the alert 19.h3. Now my opponent had chances to make my life uncomfortable, and I was fortunate that he did not torture me as much as he could have.

20.Kf2 Qh4+

After the game Rybka preferred 20... Re8, and showed that White would be fine after 21.Ne2 Nd5 22.Ke1+ Kg8 23.Bd2 b5 24.Rc1 c5 25.Kd1 Rf8 26.Qg1 Qe5 27.Rb1 Re8 28.Qf1 c4 29.dxc4 bxc4 30.Ng1.




analysis diagram








Uh, right...


21.Ke2 Kg8

I was very happy to see Black block his Rook from the e-file.

22.Bd2 Qg4+ 23. Qf3 Qe6+ 24.Kf2 Ng4+


Enter: the Knight.

25.Kg3 Nh2

I would not be surprised to learn that my opponent was feeling a bit dizzy, himself. This move allowed me to exchange Queens – and win the Knight.

26.Qd5 Qxd5 27.Nxd5 c6


This move is a slight distraction from the fact that Black's Knight has no safe retreat.

28.Nc3 Kf7 29.Rh1 Black resigned

(Horse)fly in the Ointment

The Blackburne Defense to the Jerome Gambit, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 d6, is probably the best known of the Jerome Gambit refutations, considered to be either winning for Black, better for White, or leading to a drawn game, depending upon your resource.

It was showcased in the most widely-known Jerome Gambit game, Amateur - Blackburne, London, 1885 (see "Nobody expects the Jerome Gambit!", "Mars Attacks!" and "One More Time"), which featured a scintillating attack by Black(burne), topped off by a Queen sacrifice and a jaunty checkmate.

The opportunity to pull off The Black Death's coup de grâce is an irresistible attraction...

KONB - elmflare
standard game, FICS, 2011

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


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 d6



Here we go! Black offers to return material. White can take the Rook if he knows how to defend and counter-attack. Sometimes he does, and sometimes he doesn't...

8.Qxh8 Qh4 9.0-0 Nf6


[Sound of a door slamming shut on the White Queen...]

10.Nc3

Amateur - Blackburne, London 1885 continued with the similarly ineffective 10.c3 Ng4 11.h3 Bxf2+ 12.Kh1 Bf5 13.Qxa8 Qxh3+ 14.gxh3 Bxe4 mate.




analysis diagram








The escape hatch for White is 10.Qd8.

Now Black pours it on. 

10...Ng4 11.h3 Bxf2+ 12.Kh1 Bf5 13.Qxa8


Here, take the other Rook, too!

13...Qxh3+

And now... Wait, wait a minute  there's a fly in the ointment here...

14.gxh3 Bxe4+ 15.Nxe4


Oh, yeah, that's right, White played 10.Nc3, not 10.c3. It makes a difference.

Black resigned.

I'm sure he immediately saw that 13...Qg3 would have forced checkmate.

Nudge 2.0

The other day Bill Wall told me that there were 5 Jerome Gambit games (out of over 4.8 million) in the new Big Database 2011 from ChessBase. It turns out that 2 of them were unknown to me. Here's one.

Kitzler,G - Schloeffel,C
Karl Mala Memorial FICS, 2009

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


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


7.Qxc5

Instead of this direct capture, I prefer the "nudge" 7.Qd5+ which usually pushes Black's King to the back rank, where it can interfere with the development of his King Rook. It costs me an extra tempo, but Black returns it with a later ...Kf7 or ...Ke7.

7...d6 8.Qd5+

I suppose that this move could be a "nudge 2.0" as it either moves Black's King, or the Queen's check is blocked by Black's light-squared Bishop, which in turn makes the b7 pawn available for capture.

How good is the move? Well, there are 127 games with it in The Database, and White scores only 37%. On the other hand, the move has been played by Jerome Gambit stalwarts blackburne, AAlekhine and Bill Wall, and was chosen by computers Crafty 19.19 and Yace Paderborn in their games against RevvedUp.

8...Be6 9.Qxb7

Black willingly gives up the pawn and White happily takes it. At least one of them apparently remembers what happens to one who takes the Queen's Knight pawn...

As in many Jerome Gambit positions, Black is "objectively" better, but if White can consolidate his position (he is behind in development and his King is not safe) then in casual or club games White's extra 3 pawns may be able to balance out Black's extra piece.

9...Nf4

Two other possibilities:

9...Nf6 10.d4 Re8 11.Nc3 Qc8 12.Qb5 Bd7 13.Qd3 Nxe4 14.0-0 Kg8 15.Bg5 Nxg5 16.Rae1 c6 17.Qc4+ d5 18.Qd3 Rxe1 19.Rxe1 Bf5 20.Qd2 Ne4 21.Nxe4 Bxe4 22.f3 Bf5 23.g4 Bxg4 24.fxg4 Qxg4+ 25.Kh1 Nh4 26.Qe2 Qxe2 27.Rxe2 Rf8 28.h3 Kf7 29.Re3 Re8 30.Rxe8 Kxe8 31.c3 Ke7 32.Kg1 Ke6 33.Kf2 Kf5 34.Kg3 g5 35.a4 h5 36.b3 Ke4 37.Kf2 Kd3 White resigned, blackburne - meliam, ChessWorld, 2004; and


9...Nh4 10.0-0 Qg5 11.Qxc7+ Ne7 12.g3 Nf3+ 13.Kh1 Qh6 14.h4 Bh3 15.Rd1 Qe6 16.Qa5 Bf1 17.Qh5+ Ng6 18.Qxf3+ Kg8 19.Rxf1 Qh3+ 20.Kg1 Ne5 21.Qb3+ d5 22.Qxd5+ Nf7 23.Qxa8+ Black resigned, Wall - CheckMe, Chess.com, 2010.


Players who return to this line also need be aware of the unplayed 9...Qg5!? Trust me, the Black Rook on a8 is poisoned. White has to try 10.g3

10.0-0

This move seems prudent, but it actually opens up Pandora's box. White had to find 10.Rg1 and hold on, as Black has both quiet and wacky responses (try 10...Bd5!?) to try to increase his advantage.

10...Bh3

Okay, take a deep breath.

Black, as is the case in many Jerome Gambit games, has missed the killing stroke 10...Qg5, as 11.g3 causes horrible weaknesses on the white squares around White's King, i.e. 11...Ne2+ and 12...Qh5.

Instead, Black has gone in for flash (taking the Bishop now leads to a quick mate), and that means White has an extra chance. He should try 11.Qb3+, hoping for something like 11...d5 12.d4 Qg5 13.Qg3 Ne2+ 14.Kh1 Nxg3+ 15.fxg3+ Qf6 16.Rxf6+ Nxf6 17.gxh3 Nxe4 when White has two pawns for the exchange and Black will have to work for a win.

After 11.Qb3+ Ke8 12.Qb5+ White should probably exchange Queens if he has the opportunity and otherwise work on his development, again hoping that his 3 extra pawns will come to his rescue.

11.e5

Opening the route to g2 for his Queen, but now his game completely collapses. It is probably time to draw the curtain on this tragedy.

11...Bxg2 12.Qb3+ Bd5 13.e6+ Kf8 14.Re1 Bxb3 15.e7+ Nxe7 16.axb3 Nf5 17.Kh1 Nh3 18.d3 Qh4 19.Rf1 Nxf2+ 20.Kg2 Re8 21.Rxf2 Qg4+ 22.Kf1 Qh3+ 23.Rg2 Qf3+ White resigned


White's undeveloped Queenside tells the tale.

Sometimes you win, anyhow

Sometimes I look over a game that I have played and the strange thing seems to have little substance, being mostly bluster and a frantic waving of arms on my part.

On those sobering occasions, I console myself with having won the game, anyhow.


perrypawnpusher - apinheiro
blitz, FICS, 2011

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+


Despite second thoughts (see "Walking Through A Junkyard") I keep playing this line  successfully (see "Cure for Time Trouble (Part 1)").

7...Ng6

My opponent has also played 7...g6 against me in perrypawnpusher - apinheiro, blitz, FICS, 2010 (1-0, 35)

8.Qd5+ Ke8 9.Qxc5 d6 10.Qe3 N8e7


11.f4 Rf8 12.f5 Ne5 13.d4 Nc4

Varying from an earlier game between us that had continued with 13...Ng4, perrypawnpusher - apinheiro, blitz, FICS, 2010 (1-0, 59).

14.Qg3

As always: where to put the Queen?

After the game I was testing a new engine, Houdini, and it recommended 14.Qe2, instead, leading to a highly tactical line, 14...d5 15.Nc3 Nd6 16.Bxh6 gxh6 17.f6, where best play by Black can keep White's advantage to a minimum, but poor play will be punished quickly.

14...Rg8 15.Nc3 Kf8

Walking into the line of fire.

16.b3

Houdini preferred 16.Qh4 with play on the light or dark squares, depending on how Black chose to defend.

16...Nb6 17.f6

This advance is premature. I needed more developed pieces to support an attack. 

17...Ke8

It is true that after the correct 17...gxf6 White can continue 18.Bxh6+ and if 18...Kf7 thre is the exciting 19.Rxf6+!? with a continuing attack; but if Black's King retreats, instead, with 18...Ke8 White has no better than an even game.

Black's move in the game is an unfortunate oversight, and his game proceeds to unravel.

18.f7+ Kf8 19.fxg8Q+

Even stronger was 19.Bxh6.

19...Kxg8 20.Bxh6 g6 21.Rf8+ Qxf8 22.Bxf8 Kxf8


Black has only two pieces in return for his Queen, and White has open lines to continue his assault.

23.Qf4+ Kg7 24.Rf1 Be6

Losing a piece, but "best" according to Houdini was 24...Bf5, which still drops the Bishop.

25.Qf6+ Black resigned

Like a Needle in a Haystack (Part 3)

The March 1874 issue of the Dubuque Chess Journal contains a game between "Mr. S" (William A. Shinkman?) and Alonzo Wheeler Jerome – a King's Gambit won by Jerome. This was followed by further contributions by Jerome, in April and July of the same year; and in January, March, June, October and November of the following year.

Consistent with yesterday's post (see "Like a Needle in a Haystack Part 2"), after information from Jerome appeared in the March 1876 issue of the Dubuque Chess Journalnew items began to appear in Hallock's American Chess Journal, in June, September, October, November and December of 1876. Alonzo Wheeler Jerome had begun corresponding with the "new" chess journal.

Jerome contributed to the February, March and April 1877 issues of the American Chess Journal, and then seems to have lost contact or interest. Hallock's ACJ ended publication December 1877.

Brownson's Chess Journal had one Jerome item that year, in March of 1877

For the Jerome Opening play a few games by correspondence with A. W. Jerome (the inventor), P.O. address, Paxton, Ford Co., Illinois, and try it over the board when the opportunity offers. It is brilliant.
(Ten years later, the May 1887 issue of Brownson's Chess Journal published an unusual Giuoco Piano with Jerome playing Black.)

What publication did A.W. Jerome correspond with after the American Chess Journal ? The trail grows cold...

Until Jerome appears, mostly in support of S.A. Charles, in the Cincinnati Commercial Gazette and Pittsburgh Telegraph of the early 1880s (a tale for another time); and then over 20 years later, in the pages of the 1900 Literary Digest, offering to play his Gambit against readers in consultation.

Yet, just the other day I was wandering through the Chess Archaeology site (http://www.chessarch.com/) and encountered the "Jack O'Keefe Project Index" which has viewable chess columns from 33 older periodicals. By chance I happened upon some "cuttings" there from "Mackenzie's Chess Chronicle" published in Turf, Field and Farm. The August 30, 1878 column has the following
We are indebted to Mr. A. W. Jerome for some correspondence games illustrative of the new Jerome Gambit, which shall receive early attention.
Aha! The game is afoot!

Sadly, the Chess Archaeology site's collection of "Mackenzie's Chess Chronicle" runs only to December 27, of 1878, and there is no further mention of the Jerome Gambit in that span... Although that last held issue provides some foreshadowing, announcing as it does

We welcome with pleasure a new chess column in the Cincinnati Commercial. It made its first appearance in the issue of Dec. 14, and is to appear every Saturday in the daily; the column is conducted by Mr. J. W. Miller, and, judging from the two specimens we have seen, it promises to be a valuable addition to the chess periodicals.
