Jerome Gambit: Be Prepared

If you are going to play bullet chess, you have to be prepared for just about anything. The story of the following game is that Black was not prepared - for the Jerome Gambit.

1 0 bullet, lichess.org, 2020

1. e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 h6 5.O-O Bc5 6.Bxf7+ 

The Semi-Italian Four Knights Jerome Gambit.

6...Kxf7 7.Nxe5+ Nxe5 8.d4 Bxd4 9.Qxd4 

9...Qe7 10.f4 c5 

Sometimes this pawn "kick" works, sometimes it doesn't. It is best to work it out beforehand, as there is not a lot of time to figure it out as the play develops in bullet.

11.Qxe5 Qxe5 12.fxe5 Black resigned

Black will be down a piece, with no compensation.

BSJG: The Win Is The Thing

angelcamina, playing online at lichess.org, likes to play the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) and other Jerome variants in bullet games with a time control of one minute, no increment. (Kind of like heavyweight boxers, wearing roller skates, on ice.) He beats his opponents when he has the advantage, and he beats them when they have the advantage. Both ways, quickly.

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.Qh5

I have already pointed out

White's strongest move here is 6.c3, but any Queen move has to be scary for Black, and takes up thinking time to figure out how to deal with it.

6...Qf6 

A little bit stronger was 6...Nf6, as in angelcamina - rabirabi, lichess.org, 2019 (1-0, 13) and angelcamina - shahramkhoshseffat, lichess.org, 2019 (1-0, 13).

7.Ng4

A small improvement over 7.Qe8+ in angelcamina -Skhokho1507, lichess.org, 2019 (1-0, 12). 

7...Nxc2+ 

This fork is always tempting when it appears in the BSJG, but it would have been wiser to settle things down with 7...Qg6 8.Qd5+ Ke7 9.Qxd4 Qxg4 10.O-O Kd8, with Black for choice. 

8.Kd1 Qg6 9.Qd5+ Ke7 10.Ne5 Qe6 

11.Qxe6+ 

The Queens probably have to be exchanged, but 11.Kxc2 Qxd5 12.exd5 was the way to do it, with a roughly balanced game. With the text, White sheds his advantage - which only means he has to work a little bit harder.

11...Kxe6 12.Kxc2 Kxe5 13.d3 d5 14.f4+ Kd4 

Inexplicably headed for trouble. angelcamina obliges. 

15.Re1 Be6 16.Be3 checkmate

Jerome Gambit: Careful What You Wish For

?!?

Now that you have what you want, do you really want what you have?

The above question appears twice in the first six moves of the following game. The game turns on the answer to each of the questions.

Wall, Bill - Guest1573554
PlayChess.com, 2020.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 

"The Italian Game", perhaps Black muses. "I wish I had a few more defenders to play against it."

4.Bxf7+

4...Kxf7 5.Nxe5+ Nxe5 

"Wow! An extra Knight and an extra Bishop!" celebrates Black.

"I would like to get a return on my investment," thinks White. "As in my earlier games."

6.Qh5+ Kf6 

"This will do," smiles White.

7.Qf5+ Ke7 8.Qxe5+ 

Black resigned here in Wall,B - Guest2892618, PlayChess.com, 2015.


8...Kf8 

Or 8...Kf7 as in Wall,B - Guest1468523, PlayChess.com, 2013 (1-0, 14). 

9.Qxc5+ d6 

Bill has also seen 9...Ne7, as in Wall,B - SMNN, FICS, 2013 (1-0, 27). 

White has regained his two sacrificed pieces, and remains two pawns up. There is still more work to do, but this is a decent start.

In the meantime, too, Black has to figure out what he is going to do.

10.Qb5 Nf6 

Or 10...c6 as in Wall,B - Guest733407, PlayChess.com 2014 (1-0, 21).

11.O-O 

White could have protected his e-pawn  - e.g. 11.d3 as in Wall,B - KSPF, FICS, 2011 (1-0, 23) - but he would happily respond to 11...Nxe4 now with 12.Re1.

11...h5

Black considers activating his Rook, to attack White's King. He is not finished fighting - but what to do?. Perhaps White's Queen is misplaced?

12.d3 Ng4 13.Nc3 c6 14.Qb3 Qe7 

Where to put the Queen? Can the Bishop move without giving up a pawn? Must the King Rook stay at home? Things to figure out.

15.f4 h4 16.h3 Nf6 17.f5 Black resigned

I think Black decided that his game was just too uncomfortable, and that there were better opportunites, elsewhere.

Jerome Gambit: Not So Drawish Line

The Four Knights Opening has a reputation for being somewhat drawish, so Black, in the following game, might have relaxed a bit when his offer of an Alekhine's Defense turned into a Four Knghts.

Of course, White's plans were anything but peaceful.

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

The Italian Four Knights Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.d4 Neg4 

The Knight escapes danger, while thinking of aggression.

Best was probably 7...Bd6, which, in the regular Jerome Gambit line (minus Nc3 and ...Nf6), would be an error. With enough time, all this can be worked out; but, in a one minute game, who has enough time? 

8.dxc5 c6 

This creates a bit of a hole at d6 in Black's position, which White will eventually exploit.

9.O-O Re8 10.Bg5 Ne5 

The Knight seems to have lost its sense of direction. It will eventually sacrifice itself for a couple of pawns, as a "scientific" response to the gambit, but things never work out quite right.
  
11.f4 Ng6 12.e5 Nxe5 13.fxe5 Rxe5 14.Bxf6 gxf6

Material is even, and the pawn at c5 looks about ready to fall, but the first player's lead in development is what really matters.

15.Qd3 Qg8 

Protecting the h-pawn, but there is not time for that. Best was 15...Qe7, although the game would quickly slide downhill, anyhow: 16.Qxh7+ Ke8 17.Qg8+ Qf8 18.Qg6+ Kd8 19.Ne4!? another classic case of retarded development, Black's d-pawn blocking his light-squared Bishop, which, in turn, blocks in his Rook.

16.Rae1

This is a solid move, and White trades off his opponent's defender. With more time to calculate, he would have found (but didn't need) 16.Rxf6+ Kxf6 17.Re1+ and he would quickly recover his sacrificed Rook.

16...Rxe1 17.Rxe1 b6 

Struggling to free the Queenside - too late.

18.Qd6 bxc5 19.Re7+ Kg6 20.Qg3+ Kh6 21.Qxg8 Bb7 22.Rxh7 checkmate

Jerome Gambit: Another Historical "Oversight"

My game against AndrewLLL in the third round of the "Italian Game Battlegrounds" tournament at Chess.com (see the previous post) has already progressed enough that I can now correct a historical "oversight": despite my commitment to share all of my Jerome Games, regardless of outcome, on this blog, I sort of "overlooked" the game perrypawnpusher - joseluislopez, blitz, FICS, 2012 (0-1, 55).

You might notice that I lost that game against joseluislopez, and that maybe I was too embarassed to share it. That is not quite right: I did post an endgame position from our game that featured a double blunder, before my eventual loss by checkmate.

Yet, fair is fair, so here is the game - with a couple of lessons to learn.

perrypawnpusher - joseluislopez
blitz, FICS, 2012

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

The Italian Four Knights Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.d4 Bd6 8.dxe5 Bxe5 

9.f4

Starting the advance of the "Jerome pawns".

9...Bxc3+ 10.bxc3 d6 

I willingly traded my Queenside pawn structure for some time - Black's Bishop moved 4 times before leaving the board, while my Knight moved once. This was probably a mistake. A master would find active play to compensate, but I am not a master. Well on into the endgame, you will still be able to see the effect of the different Queenside pawn structures.

11.O-O Bg4 12.Qd3 Re8 13.h3 Bh5 14.g4 Bg6 

So far, White is playing aggressively, in true blitz style. Black probably should have returned material with 14...Bxg4!? which would have led to some danger to White's King.

15.f5 Nxe4 

This is a mis-reading of the position, as it allows White to open the f-file. Instead, Komodo 10 suggests the bizarre 15...Bh5!?, and has Black holding on to a small advantage.

16.fxg6+ 

This move leads to White's advantage, but the alternative, 16.Qd5+, would have led to checkmate: 16...Kf8 17.fxg6+ Qf6 18.Rxf6+ Ke7 19.Rf7+ Kd8 20.Qxb7 Re7 21.Rxe7 Kxe7 22.Qxc7+ Ke8 23.gxh7 Nf6 24.h8/Q+ Ng8 25.Qxg8 checkmate..

16...Kxg6 17.Qf3 

Looking to put more pressure on the enemy King, but overlooking Black's response, which is an effective remedy. More accurate would have been 17.Qd5, when 17...Nf6 (the only move to prevent checkmate) 18.Qf5+ Kf7 19.g5 would have led to a clear advantage.

17...Qf6 

White's dynamic compensation for his structural defects has been wasted. Black now grinds his opponent down - and a significant part of his plan is to take advantage of White's isolated Queenside pawns.

18.Qxf6+ Nxf6 19.Bd2 Re4 20.Rab1 b6 21.Rb4 Rae8 22.Rxe4 Rxe4 23.Kg2 Re2+ 24.Rf2 Rxf2+ 25.Kxf2 Ne4+ 26.Ke3 Nxd2 27.Kxd2 Kg5 28.Ke3 h5 29.gxh5 Kxh5 30.Kf3 Kh4 31.Kg2 g5 32.c4 c6 33.c3 b5 34.cxb5 cxb5 35.Kh2 a5 36.Kg2 b4 37.cxb4 axb4 38.Kh2 d5 39.Kg2 d4 40.Kf3 Kxh3 41.Ke4 g4 42.Kxd4 g3 43.Kc4 g2 44.Kxb4 g1=Q 45.a4 Qb6+ 46.Ka3 Kg4 47.Ka2 Kf4 48.Ka3 Ke4 49.Ka2 

I do not remember why I was playing on, a Queen down; most likely, my opponent was short of time. Only a miracle would save me - and I was not ready, when it came.

49...Qb5?? 50.Ka3?? 

Capturing the Queen would have led to a draw, even a pawn up. Probably I was short of time, too.

50...Qa5 51.Kb3 Kd4 52.Ka3 Qc3+ 53.Ka2 Qb4 54.Ka1 Kc3 55.a5 Qb2 checkmate

(My personal notes to this game suggested that I avoid 9.f4, and try something like 9.Ne2 - which I did, against AndrewLLL. We shall see how that works out.)

Jerome Gambit: Ever Onward

The third round of Chess.com's "Italian game Battlegrounds" tournament has started, and I find myself in Group 2 - which consists of me and andrewLLL.

As always, I was fully prepared to place my chances for success in the hands of the Jerome Gambit, but a review of my opponent's recent games suggests that he much preferred 3...Nf6, the Two Knights Defense, to 3...Bc5, which would limit my Jerome options.

So, after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6, I crossed my fingers and played 4.Nc3, fully expecting 4...Nxe4, when I was resigned to returning to last year's site of grave strugggle with the Noa Gambit against RemoveKubab1 with 5.Bxf7+.

However, perhaps andrewLLL got a hint of the won game looming before him, and played, instead, 4...Bc5, allowing me to move the game into the Italian Four Knights Jerome Gambit with 5.Bxf7+.

The Database shows that I have played this line in 60 games, scoring 74%, but you never know when it comes to "refuted" openings, do you? 

Jerome Gambit: Deep Dive (Part 3)

[continued from the previous post]

ZahariSokolov - GizmoClass
FICS, 2019

If you are attacking, and you slip up, you might be down some material. If you are defending, and you slip up, you might be down your King. Keep this bit of wisdom in mind, as the game progresses.

19...Bh3 

Black senses he has time to strike back, not only defend. He misses a couple of points.

First, White still has the threat of 20.Bb4, skewering Black's Queen and winning the Knight on e7; that was why 19...a5, covering the b4 square, instead of the text, was essential.

Second, White's last move contains the threat Qxb5 checkmate, if Black should ever move his Queen away from protecting the pawn at b5 - making 20.Be3, pinning and winning the Queen, a grave danger. (If 20...d4, then 21.Bxd4.)

20.Re1 

Saving the Rook, but missing the winning move just mentioned.

The game now has the feel of time pressure about it. 

20...Bg2 

Continuing to overlook the main threat, as does his opponent. 

21.exd5 Bxf3+ 22.Kc1 Bxd5 23.c4 

Dizzying. White did not have 23.Be3 at his disposal, instead of the text, because of 23...Qxe3+ 24.Rxe3 Bxb3 25.Rxe7 Rae8 26.Rxe8 Rxe8 27.Ke2 Bf7, and Black would have a piece for a pawn.

23...a6 

Not appreciating the fact that White's last pawn move restored a major threat. Better was 23...Kb7, tip-toeing away from the Bishop pin, and, after 24.Re5 Rhd8, maintaining a roughly balanced game.

24.Be3

Yes.

24.Bxc4  25. Bxc5+ Kxc5 26. dxc4 b4 27. Qe3+ Black resigned

Quite a battle!
