Jerome Gambit: Risk Upon risk

If it is risky to play the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), it is even more so to play it at the time control of one minute, no increment. And, to do so - blindfold?

If risky, also exciting, as the latest game from private eye Cliff Hardy shows us. He even shares one of his "secret weapons" in bullet play. Enjoy! [I have added diagrams, but the commentary is by Cliff. - Rick]

Hi Rick!

OK, I'm sorry to inflict this on you again but I like to try playing the Jerome Gambit under different conditions and against different opponents and have included a blindfold bullet Jerome Gambit game I played. Naturally, my opponent would not have played the game blindfolded (well, actually, I guess you never know, but there aren't many of us who are crazy enough to do it, so I rather doubt it ðŸ˜‰). 

Cliff Hardy - NN
1 0 bullet, Lichess, 2020

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



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 



7.Qd5+ Kf8 8.Qxc5+ d6 9.Qe3 Qf6 




10.0-0 N8e7?! =+

Stockfish gives best as 10...Nf4! 11.d3 g5, grabbing space, with a clear advantage for Black, but I admit that it doesn't seem quite so clear an advantage to me.

11.Nc3?! -++

And better here would have been 11.d3!, to stop the ...Nf4! move from being playable again.

11...c6? +=

11...Nf4!

12.d4 Kf7 13.f4 Rf8 14.f5 Nh4?! +-


14...Kg8! += would have left the knight on g6 immune from capture, due to mate on f1.

15.Qd3 

I missed that I could have trapped the knight here with 15.g3?, though Stockfish says that after that, Black could then have given back the piece advantageously with 15...Nhxf5! 16.exf5 Nxf5, upon which he then would have had a slight edge.

15...Kg8 16.g3? -+

Surprisingly a mistake, for reasons along the line of those given on the previous move. Better would have been to have grabbed space with 16.g4! +-.

16...Nhxf5! 17.exf5 Nxf5? =


17...Bxf5! -++ would have been a more forcing and better way to capture here, as it would have attacked the queen and forced White to have wasted a tempo to save it.

18.Ne4 Qg6?! =

18...Qxd4+! 19.Qxd4 Nxd4 20.Rxf8+ Kxf8 21.Nxd6 Nxc2 -++ was a bit too hard to see under the conditions of a bullet game.

19.Be3 d5 20.Nf2? 

20.Ng5 =+ would have been less defensive.

20...h5?! =+

20...Nxe3 21.Qxe3 Qxc2 -++ would have won a pawn.

21.Rae1 h4 22.Bf4 hxg3 23.Bxg3 



23...Nxg3?? 24.hxg3??

Oops? OK, taking the free queen with 24.Qxg6 would have been rather better. Hopefully if I'd been playing sighted I might have seen that! But hey, at least missing it made it more of an even game! ðŸ˜‰

24...Qxd3? = 

24...Bf5! 25.Qc3 Bxc2 -++ would have won another pawn.

25. cxd3?! =+ 

25.Nxd3 = would have kept a better pawn structure.


25...Bh3?? ++- 

Another oops!

26.Nxh3 Rxf1+ 27.Rxf1 Rf8 28.Rf2 Rxf2 29.Kxf2 Kf7 



30.Ke2 g6 31.Kd2 Kf6 32.Kc1 

I admit that my blindfold bullet games often deteriorate into this sort of thing. I'd forgotten where the pieces were and was just shuffling my king back and forth, aiming for the win on time! Sorry, but that's the advantage of having no shame!

32...Kf5 33.Kd1 Kg4 34.Kd2?? Kxh3 -++


Black's position was now totally winning as his g-pawn was unstoppable, though he now had less than 0.1 of a second left on his clock.

35.Ke1 Kxg3 36.Kd2 Kg2 37.Ke2 and White won on time, still with a good 22.1 seconds left on the clock ðŸ˜‰.


Bye,

Sarrat Attack: No Way A World Champion...

In my never-ending search to uncover not only Jerome Gambit and Jerome-ish games, but also possible precursors that might have inspired Alonzo Wheeler Jerome to create his gambit, I have run across a number of interesting, if old, openings. 

For example, in "No Way A GM Plays the Jerome Gambit! (Part 1, Part 2 and Part 3)" I looked at a couple modern examples of the Sarratt Attack (1.e4 e5 2.Nf3 Nc6 3.d4 exd4 4.Bc4 Bc5 5.Ng5 Nh6 6.Nxf7 Nxf7 7.Bxf7+ Kxf7 8.Qh5+): Grischuk, A. - Karjakin, Sergey, St. Louis Blitz, St. Louis, 2018 (1/2-1/2 69) and Grischuk, A. - Dominguez Perez, L., St. Louis Blitz, St. Louis, 2018 (1-0, 43).


This was all very interesting, as I had noted in my post "The Sarratt Attack"
Of the Sarrat / Vitzthum Attack (see the recent "Another Distant Relative" as well as "A Bridge To... Somewhere" and "Abridged"), The City of London Chess Magazine wrote in 1875
This attack, invented by Count Vitzthum, was very much practised about twenty years ago. [Here, Readers may recall Meek - Morphy, Mobile, Alabama, 1855Meek - Morphy, New Orleans, 1855; and Kennicott - Morphy, New York, 1857 as examples; although Lowenthal, in Morphy's Games (1860), had already opined "This {5.Ng5}is far from an effective mode of proceeding with the attack, and is decidedly inferior to castling" and "This mode of proceeding with the attack is comparatively obsolete, as with the correct play the defense is perfectly satisfactory." ] It is now abandoned in contests of strong players, as the analysis proved that Black can maintain his Pawn with a good position.
Recently, however, I ran across the following game:

Carlsen, Magnus - Vidit, Santosh Gujrathi
Tata Steel Rapid and Blitz, 2019

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.d4 exd4 5.Ng5
  drawn




GM Vidit was rated 2722, but, when a World Champion offers you a draw...

A GM Faces the BSJG: Not Quite (Part 4)

[continued from previous post]

Regarding the early Blackburne Shilling Jerome Gambit game that we have been looking at ("A GM Faces the BSJG: Not Quite, Parts 1, 2 and 3"), Nater, Carl - Rogers, Ian, Begonia op 09th, Ballarat, 1975 (0-1, 46 ), I was able to contact GM Rogers, who, in turn, was able to contact Mr. Nater.

Not surprisingly, GM Rogers said that he was shocked to see his 1.e4 e5 2.Nf3, Nc6 3.Bc4 Nd4 met by 4.Bxf7+!?. At first, he expected simply be able to refute the move, as he not had it played against him previously - and actually had not even seen it mentioned before. He settled himself down and outplayed his opponent, for the full point.

"I gave up 3...Nd4 soon after that game for multiple reasons, not least that it was a bad move!" was GM Rogers' assessment.

Mr. Nater, rather than claiming to be one of the world's foremost experts on playing the Blackburne Shilling Jerome Gambit over-the-board, modestly reported that "my openings at my prime [around ’75 probably] may have dived as deep as 4/5 moves before descending into chaos ... nowadays worse still." Not surprisingly, he did not have access to game score sheets from 45 years ago, so he could not say if he had repeated (or was repeating) his moment of chess opening inspiration.

"But there doesn't seem to be too much wrong with 4.Bxf7, more wrong with 3...Nd4" was his assessment.

My thanks to GM Rogers and Mr. Nater, for their comments - and for producing a very interesting game!

A GM Faces the BSJG: Not Quite (Part 3)

[continued from previous post]

We continue to examine how a future GM handles the Blackburne Shilling Jerome Gambit.

Nater, Carl - Rogers, Ian
Begonia op 09th, Ballarat, 1975



Black has two pieces for a Rook and three pawns.

9.Na3 d5 10.c3 Qe7 11.O-O 

Bringing the King to safety, although 11.d3 was a bit better.

11...Ne2+ 12.Kh1 Nh5 

White's Queen is stalemated. Nater launches a rescue mission.

13.d4 Be6 14.exd5 

Instead, Komodo 10 prefers some tactics: 14.Re1 Nxc1 15.exd5 Nf4 16.Raxc1 Qg5 17.Rxe6+ Nxe6 18.Re1 Qxd5, siding with White's three pawns versus Black's extra piece.

14...Bxd5 15.Qe5 Qxe5 16.dxe5 Bxa3 17.bxa3 Kf7 



18.Be3 Rh8 19.Rfe1 Bc4 20.Rab1 b6 21.Rb4 Bd3


22.c4 c5 23.Rb2 Nhf4 24.Bxf4 

This helps Black untangle his jumbled up pieces. The computer recommends, instead, 24.Rd2 Rd8, when it is tempting to suggest wholesale exchanges: 25.Rxd3 Rxd3 26.g3 Nd4 27.Bxf4 Rxa3 28.Be3 Rxa2 29.Bxd4 cxd4 30.Rd1 Rxf2 31.Rxd4 Rc2 32.Rd7+ Ke6 33.Rxa7 Rxc4 34.Rg7 and the game should be drawn.

24...Nxf4 25.g3 Ne6 26.Rc1 

He might have done better to protect his passed pawn with 26.f4. The game is beginning to slip away.

26...Nd4 27.Rc3 Be4+ 28.Kg1 Nf3+ 29.Rxf3+ 



A decision that will be understandable to many Jerome Gambit players: White goes with the extra pawns against the extra piece.

In club play, the pawns probably have a practical advantage; but a strong player can use the extra piece to show that he has many targets to attack, that the game is his

29...Bxf3 30.Rb3 Be2 31.Rc3 Rd8 



The pieces start to dominate, for example, 32.f4 Rd4 and one pawn will quickly fall.

32.e6+

A trick that Rogers does not fall for: 32...Kxe6 33.Re3+, winning the Bishop.

 32...Ke7 33.Rc2 Bf3 

All of a sudden, threatening checkmate.

34.Rc1 Rd1+ 35.Rxd1 Bxd1 



Again, at first glance, I (a middling club player) would be inclined to take White, here - but Komodo 10 tells the real story, rating Black as more than a Rook ahead.

Rogers' hungry Bishop now cleans up the hapless pawns.

36.f4 Be2 37.Kf2 Bxc4 38.Ke3 Bxe6 39.Kf3 b5 40.g4 c4 41.f5 gxf5 42.gxf5 Bxf5 43.Ke3 Bb1 44.Kd4 Bxa2 45.Kc3 a5 46.a4 b4+ White resigned

Hats off to Carl Nater, for his early play of the Blackburne Shilling Jerome Gambit. I hope to hear from him about the game, and his use of 4.Bxf7+.

Hats off, too, to Ian Rogers, future Grandmaster, for the chess lesson: he was surprised in his own trappy opening, but settled himself down and steadily outplayed his opponent.

A GM Faces the BSJG: Not Quite (Part 2)

[continued from previous post]

In the previous post, I mused
Last year, on this blog, I had a lot of fun looking at the idea of a Grandmaster playing or facing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), online or over-the-board... "A GM Faces the Jerome Gambit (Part 1 and Part 2) and "Jerome Gambit: More GMs? (Part 1 and Part 2)"... 
The other day I started wondering: Did any GMs play or face the Blackburne Shilling Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+)? That search would be a different kind of task, as the game would have to feature either a rare example of a GM playing the BSG, or, even less likely, a GM playing the BSJG. But my curiosity was piqued... 
A search of The Database did not turn up any games with a player (of either color) rated 2500...

So, I next turned to my ChessBase "Big Database" (almost 6,5000,000 games), and did a search for the starting position of the Blackburne Shilling Gambit, below.

I was shocked to find 12 games where at least one of the players was rated 2500!

Closer examination, however, showed that all of the examples came from the Bird Variation of Ruy Lopez: 1.e4 e5 2.Nf3 Nc6 3.Bb5 Nd4 4.Bc4.

Still searching, however, I checked the online ChessBase Live Database, looking for 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+ games, and I came upon one with Ian Rogers playing Black.

Ian Rogers! I knew that name: Australian GM! Amazing!

Well, not quite. The game was played in 1975, a few months before Rogers turned 15, five years before he became an International Master, and ten years before he became a Grandmaster.

Let's look at the game, anyhow, as it is quite educational. 

Nater, Carl - Rogers, Ian
Begonia op 09th, Ballarat, 1975

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 

Rogers, the teenager, is feeling frisky. I don't know much about his opponent, Carl Nater (age 35 at the time of the game), but a check on the FIDE website indicates that he had a rating of 1378, so, perhaps Black wished for a quick, trappy win.

Carl Nater, 80, at the 2018 Begonia tournament. He later played at the Victorian Country Championships in 2019. Recent word from GM Rogers is that Nater is still playing chess.

4.Bxf7+ 

This is the earliest game that I have with the Blackburne Shilling Jerome Gambit, predating - by 20 years - Melao Jr, H. - Danilo, Centro Cultural, 1996: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+ Kxf7 5.Nxe5+ Ke6 6.c3 Kxe5 7.cxd4+ Kxe4 8.Qh5 Kxd4 9.d3 Bb4+ 10.Nc3 Bxc3+ 11.bxc3+ Kxc3 12.Qc5+ Kxd3 13.Qd5+ Kc3 14.Bd2+ Kb2 15.Qb3+ Kxa1 16.O-O#

4...Kxf7 5.Nxe5+ Ke8

The Database has 2,585 games with position, with White scoring 58%.

6.Qh5+ g6

If 6...Ke7, White would have a checkmate in 5, starting with 7.Qf7+.

7.Nxg6 hxg6 8.Qxh8 Nf6 



Nater opted to capture the Rook, instead of the g-pawn (with check), relying on the gain of material. 

Rogers skipped the wild 8...Nxc2+ 9.Kd1 Nxa1 10.Qxg8 Qg5 which might have given him an edge, opting, instead, for reasonable development.

Komodo 10 now sees the position as about even, with Black's piece balancing out White's 3 extra pawns. Black has a lead in development, but his King will be unable to castle.

A GM Faces the BSJG: Not Quite (Part 1)


Last year, on this blog, I had a lot of fun looking at the idea of a Grandmaster playing or facing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), online or over-the-board. You might enjoy bouncing back to "A GM Faces the Jerome Gambit (Part 1 and Part 2) and "Jerome Gambit: More GMs? (Part 1 and Part 2)".

In summary, checking The Database, I found some online games with a GM-level player (2500 or above, according to the site's rating scales), but they featured either computers, human players with a lower FIDE rating, or human players whose FIDE rating I could not confirm.

I was left with 2 online games that matched my criteria: ChessCoachUA - PArnaudov, 3 0 blitz, lichess.org2017 (1-0, 39) and Cliff Hardy - Yasser Quesada Perez, lichess, 1 0, 2019 (0-1, 54).

The other day I started wondering: Did any GMs play or face the Blackburne Shilling Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+)? That search would be a different kind of task, as the game would have to feature either a rare example of a GM playing the BSG, or, even less likely, a GM playing the BSJG. But my curiosity was piqued...

A search of The Database did not turn up any games with a player (of either color) rated 2500. In fact, there was only one game with a player rated above 2300 - but it was an interesting enough game. White is rated 2386 on the site. 

ivan767 - SanChess2005
7 2 blitz, lichess.org, 2016

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 


The Blackburne Shilling Gambit.

4.Bxf7+ 

The Blackburne Shilling Jerome Gambit.

4...Ke7 

The surprises continue: Black plays the BSG, White "Jerome-izes" it, Black declines the gambit. (SanChess2005 has played this move at least once before, in a frantic 0 minutes, 1 second increment bullet game - see "Faster Than A Speeding Neuron".)

The Database has 755 games with 4...Ke7, with White scoring 70%.

For some thoughts on the BSJG declined, see "Idées Fixes et Manqués".

5.Bc4

White is happy with the pawn he has won, and with the fact that Black will not be able to castle; so he withdraws his Bishop.

5...Ke8

Black unblocks the d8-h4 diagonal, putting the main tactical theme of the Blackburne Shilling Gambit back into play. I have called this a kind of "Jedi mind trick".

6.Nxe5

White relaxes too soon. He could have remained safely a piece up by playing 6.Nxd4 Qh4 (if 6...exd4, 7.Qh5+) 7.Nf3 Qxe4+ 8.Be2

6...Qg5 

Compare this position with one in the main line of the BSG:





analysis diagram






7.O-O Qxe5 8.c3 

8...Nb5

Retreating the Knight to c6 would maintain Black's piece-for-two-pawns material advantage, although White would be somewhat better after 9.d4, because of his better pawn center and Black's less safe King.

9.d4 Qe7 10.Bxb5 c6 11.Bc4 b5 12.Bb3 Nf6 13.e5 Nd5 14.Nd2 Qg5 

White is better, but he has some work to do.

15.Ne4 Qg6 16.Re1 Bb7 17.Nd6+ Bxd6 18.exd6+ Kd8 19.Bxd5 cxd5 20.Bf4 Rf8 21.Be5 Qf5



22.a4

White wants to open a line for his Rook, and he is not afraid to offer his f2 pawn.

23...Qxf2+ 23.Kh1 Qxb2 24.Rb1 Qxc3 



All of this moving of the Queen is risky - in fact, White now has a checkmate in 11 moves, although it is hard to find in this complicated position, especially in blitz.

25.Rxb5 

Even stronger was 25.Bxg7, because Black's Rook cannot move.

25...Ba6 26.Rc5 

This saves his Rook but lets much of the energy escape from the position. White should go after the enemy Queen, but by playing 26.Rf1 Re8 27.Rf3, not the text. Once the Black Queen is moved away from covering the e1 square, White's Queen can go there - and then on to h5, with checkmate threats.

26...Qd3 27.Qxd3 Bxd3 28.Bxg7 Rf7 



White is a pawn up.

29.Bh6 Bc4 

Instead, after 29...Rf1+ 30.Rxf1 Bxf1 White will have to work for the point. 

30.Bg5+ Black resigned



It is checkmate in 3 more moves.
