Jerome Gambit: Weak Defense

The following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) blitz game was a quick lesson for Black: Take the time, even in blitz, to put together a defense that keeps you in the game.

LuisDiego2005 - riosjose26

3 0 blitz, lichess.org, 2020

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 

7.f4 Nf7 

Unusual, and not so good. There are 20 other games with this move in The Database. Over all, White scores 81%

 8.Qxc5 Qh4+ 

Loosening White's Kingside, but just because White's Queen can fly around doesn't mean that Black's Queen should fly around, too. 

9.g3 Qf6

Black avoids the tragedy of 9...Qe7 10.Qd5+ Black resigned Guest8407642325 - Guest7600400036, 10 0 blitz, Chess.com,2021 and, further, 11...Kf6 12.Qf5 checkmate Wall, Bill - Edaison, FICS, 2010.

10.f5+ 

But this is hardly a better outcome.

Jerome Gambit: Puzzle Pieces (Part 2)

 

As in yesterday's post, the following complex game (and its notes) assembles several different Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) topics covered recently on this blog.

Again I benefit from analysis by Yury V. Bukayev in his "Jerome Gambit: Article". 

Enjoy the excitment.

DutchLiLi - ahmad_2022

3 0 blitz, lichess.org, 2020

Again, this game comes as part of over 100 that Dan Middlemiss, a Jerome and Stafford Gambit afficonado, recently sent me. All of the games were played at lichess.org by DutchLiLi.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 

7.b4 

Similar to the games presented in the previous post, but without the White Queen's intervention at f5 followed by Black's King's shuffle to d6. Of course, there are possible transpositions.

8...Ng6 

I can understand the Knight wanting to watch the enemy Queen from up close, but 8...Nc6 was safer and stronger. 

There was also 8...Qf6 9.f5+?! (mouse slip?) Ke7 10.O-O g6 11.fxg6 Bc5+ 12.d4 Bxd4+ White resigned, DutchLiLi - NadyBeshara66, lichess.org, 2020.

9.f5+ Kf6 10.Bb2+ 

In a hurry to get the Bishop on the diagonal, but probably 10.fxg6 was stronger. Perhaps he anticipated Black's response?

10...Ne5 

Understandable under the time constraints of a 3 minute blitz game -  plus the position was quite complex, e.g. 10...Ke7 11.fxg6 Nf6 12.Bxf6+ gxf6 13.g7 Rg8 14.e5 Qe8 15.Qh4 Kd8 16.O-O Bc5+ 17.d4 Qxe5 18. dxc5 Rxg7 19. Rxf6 Qg5 20. Qxg5 Rxg5 and it is no wonder that Stockfish 13 sees White moving for a draw, 21.Nd2 Rxc5 22.Rf8+ Ke7 23.Raf1 Rxc2 24.R1f6 Rxd2 25.R8f7+ Kd8 26.Rf8+. 

11.Qh4+ g5 12.fxg6+ Kxg6 13.Qxd8 

White has a Queen and a pawn for two pieces. His biggest danger now is the clock.

13...Nf7 14.Qxc7 Nf6 15.Qg3+ Ng5 16.O-O 

Practical. He could win more material with 16.h4 h6 17.hxg5 but he doesn't need more material, he needs to win. 

16...Nfxe4 17.Qg4 d5 18.Qe2 Rg8 19.d3 Bc5+ 

Black's pieces are annoying. Maybe DutchLiLi might have been thinking here that grabbing the Knight a few moves ago might have been a good idea. He is helped by a tactic that Black probably thought would win the exchange, while it actually drops two pieces for a Rook.

20.Kh1 Nf2+ 21.Rxf2 Bxf2 22.Qxf2 Bf5 23.g4 Bxg4 24.Qf6+ Kh5 

25.h4 Nf3 26.Na3 Nxh4 27.Rg1 Bf3+ 28.Kh2 Rxg1 29.Kxg1 Rg8+

White's King has to be wondering, When will my material advantage matter? 

30.Kf2 Rg2+ 31.Ke3 Re2+ 32.Kd4 Bg2 33.Bc1 Nf3+ 34.Kc3 a6 35.Qh6+ Kg4 36.Qxh7 b5 37.Qg7+ Kh3 38.Qh6+ 

Finally White's King has found safety, and his Bishop is helping with the attack.

38...Kg3 39.Qg6+ Kf2 40.Kb4 Re1 41.Bf4 

Black's pieces are working hard to provide shelter, and White's best strategy might be to pick off the enemy pawns and advance one of his own. Of course, exchanging minor pieces would be of benefit for the attacker.

However, here Black lost on time.

Jerome Gambit: Puzzle Pieces (Part 1)

 

The following game (and its notes) puts together several different Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) topics covered recently on this blog.

DutchLiLi - gureye

3 0 blitz, lichess.org, 2021

Dan Middlemiss, a Jerome and Stafford Gambit afficonado, recently sent me a collection of over 100 Jerome Gambit games played at lichess.org by DutchLiLi.

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 

7.Qf5+ Kd6 8.b4 

This move had not received any analysis until Yury V. Bukayev considered it in "Jerome Gambit: Article". It is quite likely that a number of players were influenced by his work, as shown in the games below.

8...Ne7 

This is an interesting take on the "three-pieces-vs-the-Queen defense" that suffers from not having been worked out deep enough - not unusual for a 3-minute game.

At least three other moves deserve attention.

First there is 8...Bd4, apparently as yet unplayed, but rightly given attention by Bukayev, who points out that after 9.Nc3 (9.c3? Nd3+! 10.Kd1 Nxf2+ 11.Ke2 Nxh1 with the idea ...Ke7, Black wins, Bukayev;  or 9.Ba3 Bxa1 10.b5+ c5 Black wins, Bukayev) 9...Bxc3 10.dxc3 Qf6 Black wins.

Then there is 8...Bb6, which has been seen in several games -

The problem with the text in the game is that there are too many pieces hanging, while White's Queen is active and Black's King is in danger.

White is ahead three pawns, and Black has no compensation for the material. 

Jerome Gambit: It Is Best to Go All In

 

In the following Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game, Black enters into the complicated and dangerous attacking  "Nibs" variation, only to decide to then retreat his Queen for safety reasons.

The result is as might be expected.

 

SensGuy - vosloo_choppist

2 1 bullet, lichess.org, 2021

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+  

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 

7.Qf5+ Kd6 8.f4 Qh4+ 9.g3 Nf3+ 10.Kd1 

This is a complicated position - The Database has 33 games, with White scoring 59% - although the computer clearly prefers Black. Generally you don't get here on a whim.

However, Black now has second thoughts - about the way I feel when a roller coaster reaches the top of the first hill...

BSJG: Reaching Too Far

 

The following Blackburne Shilling Jerome Gambit is a good example of the defender over-reaching. 

First, rather than play a regular Italian Game, he tries the Blackburne Shilling Gambit.

Then, he underestimates the Jerome Gambit version of the BSG.

Finally, he makes a grab for a "free" Rook that turns out to be anything but free.

It cannot be much of a surprise that he lasts an unlucky 13 moves.

JefferyLu1 - Andymurray2811

3 0 blitz, lichess.org, 2021

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 

The Blackburne Shilling Gambit. White has a number of reasonable replies, including 4.Nxd4, 4.d3, 4.c3 and 4.0-0.

What Black is really hoping is that White will play 4.Nxe5, so he can respond with 4...Qg5 and complications. In a 3-minute game, that just might work.

4.Bxf7+ 

Applying the Jerome remedy, however: the Blackburne Shilling Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke8 6.Qh5+ g6 7.Nxg6 hxg6 8.Qxg6+ 

Declining the Rook - he could have tried entering the wild position after 8.Qxh8 Nxc2+ 9.Kc1 Nxa8 10.Qxg8 Qg5.

White must have something planned. Black should be wary.

8...Ke7 9.d3 Nxc2+ 

A free Rook!

Black is much more interested in being a Rook and two pieces up than in exploring the more reasonable 9...Ne6 10.Bg5+ Nxg5 11.Qxg5+ Nf6 12.e5 Kf7 13.exf6 d5  when White would wind up with 3 or 4 pawns for his sacrificed piece.

10.Kd1 Nxa1 

It is interesting that Stockfish 13, which has little appreciation for the Jerome Gambit, suggests that instead of the text, Black "allow" White to reach a draw by repetition, 10...Bh6 11.Kxc2 Qf8 12.Bxh6 Nxh6 13.Qg5+ Ke8 14.Qe5+ Kd8 15.Qg5+ etc.

I don't know that White would be interested in a draw. I have seen in many club games that the extra pawns are at least equal to the enemy's extra piece, despite what computers tend to say. 

11.Bg5+ Nf6 12.Qxf6+ Ke8 13.Qg6 checkmate

Pretty.

Jerome Gambit: Box Load of Fun

Dan Middlemiss sent me over 100 Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) games played on lichess.org by DutchLiLi, someone who really seems to enjoy the opening.

This has provided me an opportunity to see what lines DutchLiLi likes, and what success they have brought. The following game is a good illustration.

DutchLiLi - winielicaballero

3 0 blitz, lichess.org, 2020

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 

7.Qxc5 d6 8.Qb5 

This move - which poses the question, Can Black develop his light square Bishop at the cost of the b-pawn? - is a favorite of DutchLiLi's. He has scored 25 - 13 - 4 (64%) with it, which is pretty convincing.

8...Nf6 9.d3 Re8 10.Qb3+ Be6 11.Qxb7 Bd5 

Black has a sharp retort to the pawn capture, and has to have been a bit scary considering the time control - 3-minute blitz - but White keeps his compusure.

12.Qb4 Nxe4 

Nice.

13.O-O Rb8 14.Qa3 

White's Queen's excursion seems to have been a bit costly, but there are still too factors that are on the first player's side.

14...Nxf2 

Here is the first: the position remains complicated, something which favors the player more familiar and comfortable with the opening. 

Instead of the text, Stockfish 13 recommends the not-so-exciting repositioning of the Knight with 14...Ng5.

15.Nc3 

Strong enough to give White a slight advantage.

15...Qh4 

How can this not be a win for Black? At least that must have been what Black was thinking, even if the clock limited the depth of his analysis.

The computer's suggestion is interesting: 15...Bxg2!? 16.Kxg2 Re1!? (planning to draw after 17.Rxe1 Nh4+ 18.Kxf2 Qf5+) 17.Qa5 (hoping to get the Queen back into play, but Black brings about an even endgame ) Rxf1 18.Kxf1 Ng4 19.Qd5+ Kf8 20.Qf5+ Qf6 21.Qxf6+ Nxf6.  

16.Qxa7 

Brash, but he can get away with it.

16...Qg4 

Might as well. The mundane 16...Bb7 would allow 17.Qxf2+ clarifying things. But the text is a slip.

17.Nxd5 

And here White's second advantage played out: he won on time

Jerome Gambit: It Helps to Be Scary

When it comes to chess openings, it helps to be good.

When it comes to the Jerome Gambit and its relatives, if you can't be good, it helps to be scary.

Witness the following game.

Robepersky - JoeCee

3 5 blitz, FICS, 2021

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 

The Semi-Italian opening.

4.O-O Nf6 5.Bxf7+ 

One of the variations I call "impatient Jerome Gambits" because White cannot wait for ...Bc5 before sacrificing. The value of having that piece developed - say, after 5.Nc3 Bc5 - is that it often becomes a target for attack or capture.

5...Kxf7 6.Nxe5+ Nxe5 7.d4 

In this blitz game, Black has two extra pieces, while White has two extra pawns.

Way back in "But – Is this stuff playable?? (Part I)" I shared some of Grandmaster Nigel Davies' wisdom from his book Gambiteer I (2007)

Having examined literally thousands of club players’ games over the years, I have noticed several things:

1) The player with the more active pieces tends to win.
2) A pawn or even several pawns is rarely a decisive advantage.
3) Nobody knows much theory.
4) When  faced with aggressive play, the usual reaction is to cower.

7...Ng6 8.e5 Nh7 9.Qf3+ Kg8 10.Qd5 checkmate

We have seen different forms of this "Queen checkmates the cowering King" before.
