Jerome Gambit: Shortening the Pain

Of course, given a selection of Jerome Gambit games, it is always fun to find a short win for White. Often the game is a good lesson in "crime and punishment".

 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


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


8.O-O Ne7 9.f4 N7c6 

You attack my Knight, I will attack your Queen.

Sometimes this strategy works, but here things are about to become difficult for Black.

10.fxe5+ Ke7 

As will quickly become clear, 10...Ke8 was necessary.

11.exd6+ Ke6 

Finding the short way to the end of the game. There was only suffering after 11...Qxd6, e.g. 12.Qxg7+ Ke8 13.Qxh8+ Kd7 14.Be3 b6 15.Nc3 Nd4 16.Bxd4 h6 17.Rf7+ Kc6 18.Rf6 Qxf6 19.Qxf6+ etc.

12.Qd5+ Kd7 13.Qf5+ Kxd6 14.Qd5+ Ke7 15.Bg5+ Ke8 16.Qf7 checkmate

Jerome Gambit: Next Comes Home Brew

Working through the latest selection of Bill Wall's Jerome Gambits, I think the next criterion I use for chosing games is when Black invents his own defensive ideas to counter White's attack. I could have chosen "short games" as a criterion, although in the case of the following game, both would apply.

Wall, Bill - Guest2613563
PlayChess.com, 2017

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.d4
Bb6 



7.dxe5 Bxf2+ 

As covered in the previous post, 7...Qh4 was the sharpest response.

Instead, Black decides that if White's sacrifice of his Bishop was strong, then maybe Black should do the same thing.

8.Kxf2 Qh4+ 9.g3 Qxe4 



Previously seen was 9...Qe7 10.Rf1 Qxe5 11.Kg1+ Nf6 12.Nc3 d6 13.Nd5 c6 14.Nxf6 gxf6 15.Bf4 Qc5+ 16.Kg2 Be6 17.Qxd6 Qxd6 18.Bxd6 Rad8 19.e5 Bd5+ 20.Kg1 Ke6 21.Rxf6+ Black resigned, HauntedKnight - Wxbas, FICS, 2014

10.Re1 

Instead, 10.Qh5+ g6 11.Qf3+ Qxf3+ 12.Kxf3 was okay, although White was eventually out-played:  12...Ne7 13.Rf1 Kg7 14.Bg5 Nf5 15.Bf6+ Kg8 16.Bxh8 Kxh8 17.Nc3 Nd4+ 18.Kg2 Nxc2 19.Rf8+ Kg7 20.Rc1 Ne3+ 21.Kf3 Kxf8 22.Kxe3 d6 23.exd6 cxd6 24.Nd5 Be6 25.Nf6 Kg7 26.Ne4 Bxa2 27.Nxd6 b6 28.Rc7+ Kh6 29.h4 Rd8 30.Nf7+ Bxf7 31.Rxf7 a5 32.Rb7 Rd6 33.g4 g5 34.h5 Re6+ 35.Kf3 Rf6+ 36.Kg3 Rd6 37.Ra7 Rd3+ 38.Kf2 Rd2+ 39.Ke3 Rxb2 40.Ra6 Kg7 41.Ra7+ Kg8 42.h6 Rc2 43.Rg7+ Kh8 44.Rxg5 a4 45.Rf5 Kg8 46.Rb5 Rc6 47.g5 Kf7 48.Rf5+ Kg6 49.Kf4 Rc4+ 50.Ke5 Rc5+ White resigned, HauntedKnight - ravenga, FICS, 2014.

10...Qf5+ 

This move looks like it accomplishes two things at once, removing Her Majesty from the attack by the Rook, and attacking the endmy King. Still, the open f-file is full of danger, and putting both the Queen and King on it is asking for trouble. Safer was 10...Qc6.

11.Kg2 

Or 11.Kg1 Ne7 12.Rf1 Qxf1+ 13.Qxf1+ Ke8 14.Bg5 Rf8 15.Qc4 c6 16.Bxe7 Kxe7 17.Nc3 b5 18.Qc5+ Ke8 19.e6 dxe6 20.Qxc6+ Black resigned, bemillsy - Dubnobase, FICS, 2012.

11...b6

Planning to put the Bishop on the long diagonal and harass the enemy King. Black is caught up in his counter-attack. A little disrespect is involved, as well. 

12.Rf1 Bb7+ 13.Kg1 Black resigned



So far, in this and the previous post, we have yet to consider a tense, theoretical battle over the Jerome Gambit - but that is an important point. Black is often so underwhelmed by his opponent's opening that he fails to bring his A Game, or his B Game, or sometimes even his C Game... And White must and can take advantage of that.

Jerome Gambit: First Comes Disrespect

I just received 10 new Jerome Gambit games from Bill Wall, certainly one of the strongest players to routinely use the Jerome.

Which games to share? Which one to share first?

Those are funny questions.

I often start with a game that shows a defender who does not give the Jerome Gambit the "proper" amount of respect. Sometimes that shows up in overly casual play - because, as we all know, the Jerome is a refuted opening and therefore is hardly worth any attention at all...

In the following game the defender starts out with gusto, but loses focus before a dozen moves are played. That's okay, right? I mean, a garbage opening can be defeated with half your brain tied behind your back, right?

Wall, Bill - Guest2293428
PlayChess.com, 2017

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bb6 


A reasonable line. This is a good start.

7.dxe5 Qh4 

This is properly aggressive, even if Bill has seen it before.

8.Qf3+ Ke7 9.O-O Nh6 


Development, that's the key.

10.Nc3 Rf8 11.Nd5+ Kd8 


Uh, what was the question...? 

12.Qxf8 checkmate

If you play the Jerome Gambit, you have to grab these opportunities when they occur - and they will occur surprisingly often.

Just Look Ahead and Move!

Years ago, after playing over a number of Akiba Rubinstein's (1880 – 1961) games, I was inclined to think that he had reduced chess to a few easy steps: play 1.d4, win a pawn, exchange all the pieces, win the endgame. (Actually, it was a lot more complicated than that.)

With a chuckle, I was reminded of Rubinstein when playing over the following online blitz game by shugart. He offers a piece, Jerome Gambit style, but his opponent declines it. Like water rolling down hill, the game then progresses. It doesn't seem that there is a lot of need for tactical calculation - just look ahead and move!

Actually, it is a lot more complicated than that, as the notes show... A very eduational endgame! 

shugart - snob
3 0 blitz, FICS, 2017

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4



The Blackburne Shilling Gambit. 

4.Bxf7+ 

The Blackburne Shilling Jerome Gambit.

4...Ke7 

Black declines the gift of a piece. If you want me to take the Bishop, then I won't take the Bishop.

5.Bxg8 Rxg8 6.Nxd4 exd4 



Comfortable with an extra pawn - plus a safer King and a better pawn structure - White is comfortable letting the game unfold.

7.d3 h6 8.Qh5 d6 9.O-O Be6 10.f4 Bf7 



Black has the two Bishops. He is not in a hurry, either.

11.Qh4+ Kd7 12.Qh3+ Be6 13.f5 Bf7 14.Bf4 Kc8 15.Nd2 b6 16.Nb3 c5 

Black has secured his advanced d-pawn.

17.Qg3 Kc7 18.e5 Bxb3 19.exd6+ Bxd6 20.Bxd6+ Qxd6 21.Qxd6+ Kxd6 22.axb3 



In a 3 0 game, such exchanges happen quickly and help with the clock.

Will White's kingside pawn majority be enough?

22...Rgf8 23.g4 a5 24.Rae1 Rae8 25.Rxe8 Rxe8 26.Kf2 Rf8



It was time, instead, for Black's Rook to invade via 26...Re3, with his King to advance behind it, keeping the game balanced. White now shows how it's done.

 27.Re1 Rf7 28.Re6+ Kc7 29.Kf3 b5 30.Ra6 Re7 



The issue here is not Black's a-pawn. It is the fact that when Rooks come off the board White will have a straight-forward win.

31.Ra7+ Kd6 32.Rxe7 Kxe7 



Okay, how fast can you move your pieces? The game is barely half over.

33.h4 Kd6 34.Ke4 b4 

Now the inhuman Stockfish 8 declares a checkmate in 26, but the ticking clock will inject a few inaccuracies before White grasps the full point.

 35.g5 h5 36.Kf3 Ke5 37.f6 gxf6 38.gxf6 

The more accurate 38.g6!? was the way to win, with many hassles: 38...Ke6 39.Kf4 Ke7 40.Kf5 c4 41.bxc4 a4 42.c5 a3 43.bxa3 bxa3 44.g7 Kf7 45.c6 Kxf7 46.c7 a2 47.c8/Q a1/Q 48.Qd7+

38...Kxf6 

39.Kf4 Ke6 40.Kg5 

White should admit that he has only a draw, and mark the enemy King with 40.Ke4, keeping it out of mischief. He also should keep his King closer to home, as Black can now cause pawn mischief similar to the note above: 40...c4 41.bxc4 a4 42.c5 a3 43.c6 Ke6 and it is Black who will have a checkmate in 26!

40...Ke5 41.Kxh5 Kf4 



Black's King advances aggressively, but it needed, instead, to mark White's King with 41...Kf5 and let his pawns do the work, e.g. 42...c4.

The advantage agains shifts to White.

42.Kg6 Ke3 43.h5 Kd2 44.h6 Kxc2 45.h7 Kxb3 46.h8=Q Kxb2 



This is a pretty crazy position, but quite won for White - with enough time to think. Amazingly, there is.

47.Qe5 Kc3 48.Qxc5+ Kxd3 49.Qxa5 Kc3 50.Kf5 d3 51.Ke4 d2 52.Qc5+ Kb3 53.Qd4 Ka3 54.Qxd2 b3 



If only the pawn were on the a-file or the c-file, Black might have drawing chances.

55.Qc3 Ka2 56.Qc4 Ka3 57.Qc5+ Ka2 58.Qa5+ Kb1 59.Kd3 b2 60.Kc3 Kc1 61.Qg5+ Kb1 62.Qb5 Kc1 63.Qf1 checkmate



An amazing game for 3 0!

Jerome Gambit: Punishment Like A Lightning Bolt

The following game is another lightning affair from shugart at FICS. Both sides play relatively calmly - after White starts with the Jerome Gambit, of course - and then at one point Black slips. Punishment strikes light a lightning bolt.

shugart - kisa
1 2 lightning, FICS, 2017

 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+

18...Nh5 19.Qg4 Qh4 20.Qf3 

Continuing with the theme of trapped knights that we have seen in recent posts (see "Jerome Gambit: Quirky" and "Jerome Gambit: Beware the Calm After the Storm"), White had 20.Qxh4 Nxh4 21.f5 d5 22.g3 Nf6 23.gxh4 dxe4 24.dxe4 Nxe4 with an equal game.

Jerome Gambit: An Unusual Mate




I recently received a couple of games from chessfriend shugart, who plays at the online site FICS. The time control for each game is 1 minute, with a 2 second increment per move.

That kind of speed melts my brain, so the whole field of lightning - or bullet - chess always amazes me. Especially when it involves the Jerome Gambit.

Years ago I reviewed Bullet Chess One Minute to Mate by Hikaru Nakamura and Bruce Harper. A quote from that book is worth sharing

It is important to realize that bullet chess is not really about "truth," to the extent that some chess players use the term to refer to the objectively best moves, but rather whatever works. Bullet chess won't often help you in your search for "chess truth," although it will certainly help you learn how to play chess more quickly! But bullet chess will teach you a lot about chess psychology, as there is always a reason  that any particular move is played it may not be a good reason, and it may not have much to do with the actual position, but there is always a reason. In this book, we explore the reasons why players do what they do when they are short of time, especially when it comes to making mistakes.

Clearly, the largely unknown and often unappreciated Jerome Gambit is going to cause the defender many "huh?" moments - deadly, in and of itself, when time is of the essence.

The final position brings a smile to the face.

shugart - kisa
1 2 lightning, FICS, 2017

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4 Qf6 



Okay, commenting on moves in this game would be something like watching someone juggling chainsaws, and saying "That one over there doesn't look so sharp". But, I do have to point out that White's Queen is unprotected and at risk of being lost after ...Nf3+.

8.O-O Ne7 9.f4 N5c6 10.Qc4+ Qe6 11.Qe2 Rf8 12.Nc3 Kg8



Black has castled-by-hand. White has to give him something to worry about.

13.Be3 a6

A good sign. I remember that whenever my Chess Challenger 7 computer felt its position was fine, or it could not come up with a move that improved its position, it would begin to move its Rook pawns. That often allowed me to slowly improve my own position without disruption.

14.Rae1 d6 15.f5 Qe5 16.Bf4 Qc5+ 17.Be3 Qe5 



Will there be a draw?

18.Kh1 

White does not repeat the position. We can guess who is ahead on time.

18...Bd7 19.Bf4 Qa5 20.Bg5 Nd4



21.Qc4+ 

Tactics prevail.

21...Kh8 22.Qxd4 Nc6 23.Qc4 Rae8 24.f6 g6 25.f7 Re5 26.Bf6 checkmate
Very nice!

Jerome Gambit: Beware the Calm After the Storm

The following game starts out with the wild Jerome Gambit, which is met by one of the wildest defenses available.

White does not deliver checkmate.

Black does not deliver checkmate.

The game becomes balanced and calm.

Then White checkmates.

Wall, Bill - Guest699499

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

This is Black's sharpest response to 6.d4. I have often called it a "pie-in-the-face variation".

7.O-O Ng4 8.h3 Bb6

Probably Black's best move. Bill has faced

9.hxg4 Nf6 

Black is not too upset at having lost his Knight, as he plans to move the other one into the attack.

Two other ideas:

10.g5 Ng4 11.Qf3+ Ke8 12.Qh3 Qxh3 



Leading to a situation similar to what we recently saw in Wall, Bill - Guest709079, PlayChess.com, 2017 (1-0, 30) - Queens are exchanged, and Black's Knight is trapped. Quirky.

13.gxh3 Nxf2 14.Kxf2 Bxd4+ 15.Kg2 d6 



The game has reached a balance. Should either player be pleased with this? Black started out after a few moves with a "won" position, so he may not be happy. White threw a whole lot into a wild attack, so he may wish for more than a split point.

16.c3 Be5 17.Nd2 Bd7 18.Nf3 Bc6 19.Bd2 Bxe4 20.Rae1 Bc6 21.Bf4 Rf8 22.Bxe5 dxe5 23.Rxe5+ Kf7 



24.Kg3 Kg8 25.c4

Stockfish 8 slightly prefers 25.Rf2, keeping the game level. The Rook eventually gets there.

25...Rad8 26.Re3 Rf5 27.h4 Rdf8 28.Rf2 Rf4 29.b3 Bd7 



30.Rfe2 Rg4+ 31.Kh2 Bc6 32.Ne5 



Looking to squeeze something more out of the position.

32...Rxh4+ 33.Kg3 Rff4 34.Rd2 Re4 



Looking to swap Rooks, and enjoy a guaranteed draw, while hoping to make something out of his extra Kingside pawn?

Black has overlooked something.
