Blackburne Shilling Jerome Gambit Report Card (Part 7)

 


The Blackburne Shilling Jerome Gambit, like other Jerome Gambit variants, can lead to complex play. The following game is the last in the series, looking to see whether this blog presented useful information for playing the line, or if the first player had to go off adventuring on his own.

In this case, the help available was not enough to overcome, among other things, a rating difference of some 250 points.

Upon reflection, I need to do more investigation into the BSJG, and post more on this blog.

4...Kxf7 5.Nxe5+ Ke7


An interesting choice.

6.c3 Ne6 7.Nf3 

I was surprised to see that, according to The Database, this move is a novelty.

More frequently seen is 7.d4, a move that was covered a few months ago along with the game perrypawnpusher - HanPeng, 10 0 blitz, FICS, 2021 (1-0, 36) in the blot post "BSJG Dumpster Fire".

7... d6 8.d4 Nf6 

The game has transposing into position which appears 22 times in The Database. Black has a piece for two pawns, and an oddly placed King. Stockfish 13 rates the second player a bit more than a pawn and a half ahead, as compared to after 7.d3, when it gives Black less than a 1/3 of a pawn advantage. (Ergo, the blog had useful information.)

From here on out, Black outplays his opponent, until the game ends at move 33.

Blackburne Shilling Jerome Gambit Report Card (Part 6)

 

This post is the next-to-last in a series of posts developed after I stopped by the lichess.com website and examined a number of Blackburne Shilling Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+) games, only to see that White had scored 1 - 7 in those matches.

How much help would those players have found for their BSJG play, had they visited this blog beforehand? I wondered...

The Blackburne Shilling Jerome Gambit.

4...Kxf7 5.O-O 

If you read yesterday's post, you will not be surprised by what I have to say now.

Although there are only 10 other examples of this move in The Database, if you were to search the 3,365 previous blog posts here, you would have found absolutely nothing on this line.

True, the move is contrary to the whole idea of the BSJG, and almost every single game that I have posted (hint, hint) has continued 5.Nxe5+, but when it comes to helping the opening explorer - this blog wasn't. (The lack of specific knowledge was not the decisive factor deciding the game, but things might have taken a different turn.)

The game continued in interesting fashion.

5...Nxf3+ 6.Qxf3+ Qf6 7.Qb3+ Ke8 8.d3 Bc5 9.Be3 Bb6 10.Bxb6 axb6 


Black has the advantage of a piece for a pawn. The game lacks the usual attack on Black's King, so White develops carefully and waits for his chance.

11.Nd2 Ne7 12.c3 d6 13.f3 Be6 

14.Rf2 

A blitz oversight.

14...Bxb3 15.axb3 White resigned


Sigh.

Blackburne Shilling Jerome Gambit Report Card (Part 5)





Once more: this post is another in a series developed after I stopped by the lichess.com website and examined a number of Blackburne Shilling Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+) games, only to see that White had scored 1 - 7 in those matches.

I wanted to find out how many of those games were because of information that was missing or overlooked at this site. This can be particularly crucial in blitz game, where a player can get into trouble quickly.

The Blackburne Shilling Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke8 6.O-O 


Okay. Wow. We can stop right here. I was surpsed to find 129 games with this position in The Database; there are almost 3,365 posts on this blog; and not one discusses 6.0-0. Really.

Sure 6.c3 is suggested a number of times, but there is nothing like "stay away from 6.0-0" or "6.0-0 is not as effective as" or even "brave players might investigate 6.0-0".

Definitely a fail.

Also, if you play over the game, there is a bit of information that I probably only delivered in mirror image fashion: White's material compensation for his sacrificed piece (s) comes in the form of pawns from Black's Kingside.

6...Nf6 7.d3 Bc5 8.c3 Ne6 9.Bg5 Be7 10.Nd2 d6 11.Bxf6 Bxf6 12.Qh5+ g6 13.Nxg6 hxg6 14.Qxg6+ Ke7 


Against expectations, White will find that it is his King who is in danger. He has opened up lines against his own monarch and when Black grasps the intitative, there will be a killing attack.

15.f4 Rg8 16.Qf5 Nd4 17. Qa5 Nc2 18.Rac1 Ne3 19.Rf2 Bh4 20.g3 Bxg3 21.hxg3 Rxg3+ 22.Kh2 Qg8 23.Qxc7+ Ke8 Black won on time


So: Defnitely have to put 6.0-0 on the "to do" list.

Blackburne Shilling Jerome Gambit Report Card (Part 4)

 


Here we go again. This post is another in a series developed after I stopped by the lichess.com website and examined a number of Blackburne Shilling Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+) games, only to see that White had scored 1 - 7 in those matches.

I wanted to find out how many of those games were because of information that was missing or overlooked at this site.

I have pointed out that Black can often "solve" the various Jerome lines if he has enough time - but often he does not.

The games are usually complicated, which means that White has to be careful of his time, as well.

That is his problem in this game. White does well and plays hard - he just runs out of time, first. This is not really the fault of the information present on this blog.

Blackburne Shilling Jerome Gambit Report Card (Part 3)

 



It is tempting to explain the loss in the following game simply to the fact that when you flip a coin, sometimes it comes down "heads", sometimes it comes down "tails".

One-minute bullet games can sometimes feel that way.

Paviles (2317) - efaresco (2346)
1 0 bullet, lichess.org, 2020

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+ 


4...Kxf7 5.Nxe5+ Ke6 6.c3 Nc6
 


Well, this looks like a blog fail. After a number of suggestions over the years that "6.c3 is best", there are a couple of unannotated games - TrippL - boggus, FICS, 2008 (0-1, 34) and pigsfeet - steveod, FICS, 2012 (1-0, 27) - and a few short bits of analysis in "Those who cannot remember the past..." and "Clearly Unclear" with not a lot of guidance. 

7.Nc4 

If you looked hard into past blog posts, you could find a few bits of relative comment 
White can withdraw his Knight, 7.Nf3, with an even game; but the recommended move is 7.d4 with a poisoned pawn in the follow-up: 7...Nxe5 8.dxe5 Kxe5? 9.Qd5+ Kf6 10.Bg5+ Black resigned APe-Sali, blitz, FICS, 2009
And also
A calmer follow-up (although the game had its explosive moments) is 7.d4, which SotoG had played a year earlier: 7...Nxe5 8.dxe5 d5 9.Qg4+ Kf7 10.Qh5+ g6 11.Qf3+ Kg7 12.exd5 Bc5 13.Bf4 Ne7 14.c4 Rf8 15.Qg3 Nf5 16.Qd3 Qh4 17.g3 Bxf2+ 18.Kxf2 Nxg3 19.hxg3 Qxh1 20.e6 b6 21.Qf3 Kg8 22.Qxh1 Black resigned, SotoG - Ludek, blitz FICS, 2000...

And 

Rybka (blunder check, 5 minutes per move) suggests: 7.d4 Nxe5 8.dxe5 as well, continuing 8...Kf7 9.e6+ Ke8 10.Qh5+ g6 11.exd7+ Qxd7 12.Qe5+ Kf7 13.Qxh8 Nf6 14.Nd2 Bg7 15.Nf3 Bxh8 16.Ne5+ Ke6 17.Nxd7 Nxd7 18.Be3 b6 19.0-0-0 – absolutely out-of-this-world play for both Black and White... 

There was nothing to find on the text move, despite the fact that there are 8 previous games with it. 

7...Nf6 8.O-O Kf7 9.d4 d6 10.Qe2 Be7 11.Bg5 Re8
 

White has done well, on his own. He has the usual 2-pawns-for-a-piece material balance, slightly favoring Black.

The game continued, and Black's advantage grew, slipped away, and grew again - until he won on time in 30 moves.

Perhaps White would have done better if there had been more information to rely on.

Blackburne Shilling Jerome Gambit Report Card (Part 2)

 

Like I mentioned in the previous blog post, recently, I stopped by the lichess.com website to pick up a few Blackburne Shilling Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+) games. I grabbed the four listed in "Top games" and the four in "Recent games".

I was disappointed to see that White had scored 1 - 7 in those matches.

The first thought I had was: has this blog failed those players?

I had to know.


Mohsen3858 (2219)-  MasterAliFekri (2629)

10 0 blitz, lichess.org, 2021


1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Ke8 6.Qh5+ 

Recommended as a bit stronger is 6.c3, which can lead to a balanced game.

6...g6 7.Nxg6 hxg6 

As I noted in earlier this year in "BSJG Dumpster Fire"

Stockfish 13 prefers 7...hxg6 8.Qxh8 Nxc2+ 9.Kd1 Nxa1 10.Qxg8 Qg5 and gives Black the advantage in a messy position.

This was more of a continued discussion (of 8.Qxh8 vs 8.Qxg6+) after "A Discussion Continued" that occured 6 years ago

A number of years ago I got away with the weaker 8.Qxh8?! after 8...Nh6 when 8...Nxc2+, instead, would have led to an edge (Houdini) or an advantage (Stockfish 6) for Black after 9.Kd1 Nxa1 10.Qxg8 in perrypawnpusher - tampajake, blitz, FICS 2009 (1-0, 12).

 8.Qxh8 Nxc2+ 9.Kd1 Nxa1 10.Qxg8 Qg5 


I was surprised to see that there are 57 games in The Database with this position. Ominously, White scores 37%.

11.d3 

White wants to get his Bishop to h6, but the ugly 11.Rg1 was better.

11...Qg4+ 

Black is clearly better. It is true that he subsequently slipped a few times, giving White chances to draw, before eventually winning by checkmate in 21 moves.

The second player's win, however, was in large part due to his 400+ point rating advantage, and the attacker's choce of less-than-best lines of play.

Blackburne Shilling Jerome Gambit Report Card (Part 1)



Recently, I stopped by the lichess.com website to pick up a few Blackburne Shilling Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+) games. I grabbed the four listed in "Top games" and the four in "Recent games".

I was disappointed to see that White had scored 1 - 7 in those matches.

The first thought I had was: has this blog failed those players?

I had to know.

Here's the first game I looked at.

ElSrEdwardHyde (2563) - Zloy_Grisha2006goda (2436)

3 0 blitz, lichess.org, 2021

Yes, that's right, white is rated 2500+ - and he is playing the Blackburne Shilling Jerome Gambit!

1.e4 e5 2.Nf3 Nc6 3.Bc4Nd4 4.Bxf7+

It is not surprising that the computer at lichess.com (Stockfish, I think) labelled this move a "Mistake". The recommended moves to counter the BSG include 4.Nxd4, 4.c3, 4.0-0, 4.d3, 4.Nc3 - just not 4.Nxe5, which goes along with Black's plan to play 4...Qg5

Some players like to Jerome an opening....

4... Kxf7 5.Nxe5+ Ke7 6.c3 d6 7.cxd4 dxe5 8.dxe5 Qd3 9.Qe2 Qxe2+ 10.Kxe2


I took a look at this interesting - and largely even - position 8 years ago, in "Long Lines: Seeing Unclearly" and "Pwned!".

The game continued largely until what appears to be a time-induced error.

 43.Rg7 Bxg7 White resigned


So: 4.Bxf7+ led to an even game. It took almost 40 moves after that to turn the game into "0-1"
