Jerome Gambit: Those Jerome Pawns, Again (Part 3)

 

[continued from the previous post]

20...a5 

My opponent gives up on his Knight too soon. He could take advantage of the placement of my Queen and play 20...h6, so as to meet 21.h3 with 21...hxg5. Whether White plays 22.Qxg5 or 22.Qg3 followed by 23.Qxg5 (Stockfish's post mortem choice, although I am not sure why) Black's Knight will escape.

21.h3 a4 22.hxg4 axb3 23.axb3 Qc5 


White has the advantage of the exchange and some pawns, but the tripled, isolated g-pawns do not look very impressive.

24.Qe3 Qc8 25.Qf4 

I was not sure of a plan, but if Black had tried 25...Qc5 here, I would not have repeated the position. Still, he should have offered.

25...Bxg4 

Now I had an idea to reposition my pieces.

26.Qf7+ Kh8 27.Rf4 Be6 28.Qh5 Bg8 

29.g6 

Played mostly out of frustration - and some hope for the f7 square.

29...h6 30.Rf7 

Afterward, Stockfish 13 preferred 30.e5

30...Bxf7 31.gxf7 Rf8 


Now the central pawns are a threat.

32.e5 Qe6 33.Rf1 Kh7 34.Qf5+ 


This does more than exchange Queens, removing the blockader of the pawn at e5. I could see my way to the end now.

34...Qxf5 35.Rxf5 g6 

35...Kg6 would receive the same response.

36.e6 gxf5 Black resigned


After 37.e7 a pawn will promote.

Those "Jerome pawns!"

An impressive game by ManWithABigPlan.

Jerome Gambit: Those Jerome Pawns, Again (Part 2)

 

[continued from the previous post]

It was time to complete my development, and then make a typical Jerome Gambit "error".


perrypawnpusher - ManWithABigPlan

2d/move, Chess.com, 2021

13.Rae1 Nxg5 14.fxg5 Ng4 


White's pawns have been disarranged by the exchange of pieces, but the result has given me more to work with. After the game Stockfish 13 rated Black almost 4 pawns better, but things were about to get very messy...

15.Nb5 Qb6 

After the game had concluded, the computer at Chess.com criticized this move as a "blunder" which I thought was quite harsh. It took a while to find out what the silicon friend was all worked up about - especially because the move leads to an even game. 

16.Nxd6 Be6 

An impresive idea, but probably there was something better.

The implied threat, 16...c4+, fizzles out after 17.Kh1, when Black's Rook remains in danger.

Moving the Rook with 16...Re7 allows White to equalize with 17.e5 Qxb2 18.h3 Nxe5 19.Qd5+ Be6 20.Qxe5 Qxe5 21.Rxe5 Rd8 22.Nxb7 Rd5 23.Re2 Rxb7 24.Rxe6. An even game is not bad - at this point in the game.

It is now possible to see that Black's best 15th move would have been 15...Be6, as then 16.Nxd6 could have been met by the dual purpose 16...Rf8, taking the Rook out of danger and contesting the f-file. White could exchange Rooks with 17.Rxf8+ Qxf8 and then grab a pawn with 18.Nxb7, but this would only lead to 18...Qb8 19.Nd6 Qxb2, when 20.h3 would not win a piece as the Knight's retreat 20...Ne5 would be to a protected square and White has no chance for Qd5+.

Of course, most of this insight came to me after the game was over.

17.Nxe8 Rxe8 


White has a Rook and 2 pawns for 2 pieces. However, his passed e-pawn does not seem to be going anywhere, his b-pawn and a-pawn are in danger, and his g-pawn's future is uncertain.

18.b3 c4+ 

My opponent had a plan.

19.Kh1 c3 


This was a fine idea, and under ordinary circumstances it might well have succeeded - because I completely overlooked the threat. I mean, can't White just grab the pawn? Certainly 20.Qxc3 Rc8 21.Qd2 is material for free, right? Especially because I have a habit of grabbing material, and then suffering for it...

20.Qf4

Luckily for me, it turns out that I was after material, but in a different way. (Saved by even greater greed!) This move cuts off Black's Knight's retreat, and makes it vulnerable to 21.h3.

The real problem with 20.Qxc3? was 20...Nf2+, winning back the exchange, because 21.Kg1?, instead of the capture, would have led to 21...Nh3+ 22.Kh1 Qg1+! 23.Rxg1 Nf2 smothered checkmate!

Jerome Gambit: Those Jerome Pawns, Again (Part 1)


My latest Jerome gambit game started out in a rather organized fashion. It was only when things got messy that I was able to wrestle a better position from the hands of a prepared and well-motivated opponent. 

The passive Rook sacrifice at the end of the game allowed the "Jerome pawns" to shine, again.


perrypawnpusher - ManWithABigPlan

2d/move, Chess.com, 2021

1.e4 e5 2.Nf3 Nf6 3.Nc3 Nc6 4.Bc4 Bc5 5.Bxf7+ 


The Italian Four Knights Jerome Gambit. 

The line always makes me feel uneasy, although I generally do pretty well - The Database has 65 games with White scoring 75% - this is not as good as my results with the main line Jerome Gambit - 81% - or the Semi-Italian Jerome Gambit - 88%.

5.Kxf7 6.Nxe5+ Nxe5 7.d4 Bxd4 8.Qxd4 d6 


Black has a piece for a pawn. He is well-placed to castle-by-hand.

White has the typical Jerome strategems: he can castle either Kingside or Queenside, he can play Bc1-g5 with pressure on f6, he can advance his pawn f2-f4.

The text move is probably the strongest response.

I have also seen

8...Qe7 in perrypawnpusher - HGBoone, 6 12 blitz, FICS, 2010 (1-0, 27), perrypawnpusher - BigKalamar, 2 12 blitz, FICS, 2011 (1-0, 49), and perrypawnpusher - OudeKwakkelaar, 2 10 blitz, FICS, 2014 (1-0, 16); and

8...Re8 in perrypawnpusher - hklett, 2 12 blitz, FICS, 2010 (0-1, 20), perrypawnpusher - KaZC, 2 12 blitz, FICS, 2010 (1/2 - 1/2, 61),  perrypawnpusher - Fazmeister, 2 12 blitz, FICS, 2011 (1-0, 36),  perrypawnpusher - JoseSoza, Italian Game Tournament, Chess.com, 2012 (0-1, 34), and perrypawnpusher - spince, 2 12 blitz, FICS, 2014 (0-1, 41), 

9.O-O 

After the game, Stockfish 13 showed a slight preference for 9.Bf4 and 9.Bg5. I never considered the first move - although I now see that the early Jerome Gambit enthusiast yorgos played it 10 times, scoring 50%, a dozen years ago. I have played the second move once, in perrypawnpusher - wuolong, Chess.com, 2013 (1-0, 16). 

9... Re8 10.Bg5 c5 

Striking out at the Queen like this always seems anti-positional to me, leaving a hole at d5, but it has been successful in a number of past games.

I have also faced

10...Kg8 transposing to perrypawnpusher - hklett, 2 12 blitz, FICS, 2010 (0-1, 20) above, and 

10...Be6, in  perrypawnpusher - andrewLLL, Italian Game Battlefield, Chess.com, 2020 (1-0, 39). 

11Qd2 Kg8 12.f4 Nf7 


Black removes his Knight from attack by the pawn, protects the d-pawn and attacks the Bishop at g5. It is hard to find another move that does that much work.

Now I was ready to complete my development, and was not afraid of a possible ...Nxg5, as that would open up the f-file for my Rook and place an annoying pawn at g5.

Jerome Blow & The Shortest Checkmates: New!



I recently received a series of emails from chessfriend Yury Bukayev. I have put them together for you. They reference the line of thought started in "The Database: The Long And The Short Of It (Part 1)". 

I'd like to tell you about the new record of the fastest checkmates, and the game was serious. Thus, my elderly father Vyacheslav Bukayev is inspired by my Jerome gambit traps in my series "JG: The New in Its Opening Theory, in Its Psychology", and he said that he also created his interesting idea, so he asked me for playing with him last weekend. I agreed. Our first game (Bukayev, Vyacheslav  -  Bukayev, Yury) became very "tragical". After 1.e4 e5 2.Bc4 Bc5 3.Bxf7+ Kxf7 he played 4.Ne2, I responded 4...Qh4. Then he tried to castle his King, but he dropped his King accidentally on the square f1. I hurried to say him: "Don't worry! You'll be able to correct it during our next game!" Then after this tragical move 5.Kf1 I finished the game by 5...Qxf2#, of course. I understood what was the beginning of his plan: after 4.Ne2 Qh4 5.0-0 (instead of 5.Ng3) he provoked me to capture the pawn e4. Probably, he was inspired here by the Part 6 and the Part 7 of my Jerome gambit series. In any case, the checkmate isn't his shame here, and he agreed that a possible publishing of this our game will be absolutely normal.

 

Here are my constructed games I made today to get a record for White. All of them are joke games with a mixture of the Vidmar Joke opening and the Jerome blow. 
1.e4 e5 2.Bc4 Ke7 3.Bxf7 Kf6. Here are several ways:
4.d4 Be7 (or 4...Qe7) 5.Qf3#
4.d3 Be7 (or 4...Qe7) 5.Qf3#
4.h4 Be7 (or 4...Qe7) 5.Qf3#
4.Qh5 Be7 (or 4...Qe7) 5.Qf5# 
4.Qg4 Be7 (or 4...Qe7) 5.Qf5# 

It is fun, it's a combination of two handicap opening methods. 


Sorry, I forgot 4.Nh3 Be7 (or 4...Qe7) 5.Qf3#. Moreover, we have not "a mixture" of the Vidmar Joke opening and the Jerome blow, but a pseudofight of them! It is not a combination of GM Hikaru Nakamura's two favourite handicap opening methods, but a pseudofight of them!
I played that short game with my father 11.07 (on Sunday), it was a classical game, not a rapid. 

I have written in my previous letters about my constructed "joke" games which are "fun"... But in fact, there are no "jokes", no "fun" here. Thus, it is normal that the worst Black's "defence" leads to the fastest White's win. I may say "joke", if someone transforms it into his practice of defending for his joke goal.

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...

4.Bxf7+ 


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 Gambit.

4.Bxf7+ 

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.
