Strike when the time is right!

In an unbalanced and tactical game – such as in a Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) – opportunites for attack arrive and depart, often move-by-move. I want to share a snapshot of the following game from the almost-concluded Chessworld Jerome Gambit Thematic Tournament, where stampyshortlegs, battling for top honors, made a sacrifice in an attack on the enemy King; but in not following it up, he saw the game swing back violently against him, whereupon Haroldlee123 presented stampyshortlegs with one of his few losses.

JGTourney4 ChessWorld, 2009

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.0-0 Nf6 6.Nc3 Rf8 7.d3 Kg8 8.a3 d6 9.Bg5 Bg4 10.Nd5 Qd7 11.Bxf6 gxf6

Here we have a typical "modern" Jerome Gambit: White has a pawn for his sacrificed piece, but he has been careful to create no further weaknesses. Black has castled-by-hand, only to have the pawns in front of him be disrupted by White.

Fritz8 considers Black to be winning, of course – because of the material superiority – but suggests another "safe" move for White, here, 12.h3, kicking the enemy Bishop back to e6.

12.h3 Bxh3

Instead of retreating, however, stampyshorlegs has a different idea in mind: he will return his extra piece to bust open White's King's position. He expects that his investment of his extra piece will pay off nicely. (For a similar idea, see "Like a bull in a china shop...")

13.Nh4

An unusual defense, but White was not interested in opening things up: after 13.gxh3 Qxh3 14.Nh2 f5 Black has the initiative, the attack – and an extra pawn






analysis diagram






13...Bg4 14.Qd2 Qg7

Black plans to use the g-file for attack.

15.g3

Understandable, but this will cause more problems.

15...Bh3 16.Rfe1 Qxg3+

Ask not for whom the bell tolls, it tolls for thee.

17.Kh1


17...Bxf2

The question here is: was it reasonable to expect Black to see that the alternative, 17...Qxh4, led to mate? Look at the variations open to White: they all lose material and then allow mate.

After the text move, White has a tricky counter to try to turn the game around.

18.Rg1 Qxg1+ 19.Rxg1+ Bxg1 20.Kxg1

With two Rooks and two pawns for his Queen, Black is still winning, but he has to be bothered by the disappearance of his attack on the King. After a few less-than-best moves, he has a lost game to contend with.

20...Kf7

Making way for the Rook, but it was better to have the piece cross in front of him with 20...Rf7.

21.Qf2

Instead, 21.Qh6 and Black's King is in more danger than White's.

21...Rg8+

According to plan. Fritz8 suggests, instead: 21...Rad8 22.Qxf6+ Kg8 23.Qh6 Rd7 24.Nf6+ Rxf6 25.Qxf6 Rf7 which looks terribly unclear, but probably White has a small advantage.

22.Kh2


And White went on to win.

Photo Finish?

It's beginning to look like the 15-player, double-round robin Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) Thematic Tournament at ChessWorld will go down to the wire before a winner is determined.

Currently, stampyshortlegs holds the lead, with 20.5 points out of 26 games completed. He has leap-frogged over Piratepaul, who has 20 points out of 25 games completed.

Sir Osis of the Liver (19 points out of 28 games completed), is secure in third place.

Fourth place is occupied by DREWBEAR 63 (17 points out of 28 games); although he could be joined there by GladtoMateYou (16 points out of 27 games) or Haroldlee123 (14 points out of 25 games) – but not both, as they are playing a game against each other.

Luke Warm is sitting still with 15 points out of 28 games, as is Eddie43 with 14.5 points out of 28 games.

The Jerome Gambit has kept its score of 39%. stampyshortlegs has gained 9.5 points with the gambit, while PiratePaul and Sir Osis of the Liver have gained 9 points.

The D-word

Members of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) Gemeinde do not play their opening "with a draw in hand," but to win madly, or expire trying. Still, there can come a time when the wisest course just might be to split the point, and leave conquest for the next encounter... The following game is a lot of fun to play over, from start to finish (use the chess publisher application at the end of this post, if you wish), but I want to focus on some positions in the middle game, where choosing "the better part of valor" might have a good choice for White. 
 
TWODOGS - Haroldlee123 JGTourney4 ChessWorld, 2009

Here we have a "typical" Jerome Gambit middlegame: a real mess. Black-to-move has a choice of two captures, one which will leave him a piece ahead and one which (apparently) will leave him a Rook ahead. A simple choice? Nothing is simple in the Jerome Gambit! 16...Bxe1 The wrong choice.

White's opening 4.Bxf7+ and Black's superfluous ...h6 and later exchange of his light-squared Bishop left some clear light-squared weaknesses around his King.

White now has 17.Qf5+ and after 17...Kg8 18.Qe6+ he can produce a draw by repetition. If Black should try 17...Ke8 instead, then 18.Qg6+ either again leads to a draw by repetition – or a calamity for Black.

This can be seen after 17.Qf5+ Ke7, when 18.Rxe1 leads either to checkmate or a pile of material after 18...Ne5 19.Nc5 Kd6 20.Nxb7+, etc. Any member of the Gemeinde would be proud of such a "swindle." Of course, after the correct 16...dxd4 17.Rxe4 White will have to keep up the pressure and look elsewhere for his salvation. 17.Rxe1 Nb4

A perplexing move, not only allowing 18.Qf5+ drawing as above, but also allowing the flashy 18.Bd6+ which also draws. White's response in the game, however, allows the routine capture of his Knight, and the magic is again gone. 18.Qg6 dxe4 The light-square weaknesses are still around the Black King, but White no longer has his Knight to keep check-blockers off of f6.
19.Rxe4 Nxc2 Well, yes, this was Black's idea, although there was certainly nothing wrong with 19...Nc6. However, now White has 20.Be5 when 20...Qe7 21.Rf4 Kg8 22.Bxg7 Qxg7 again allows White to repeat positions with 23.Qe6+ Kh7 24.Qe5+ for the draw. Black can try the alternative, 20...Qg5 but after 21.Qe6 White has the better game. 20.Qf5+ Right idea, wrong time. 20...Kg8 Instead of interposing the Queen with 20...Qf6, allowing 21.Qc5+ and 22.Qxc2, reducing his advantage, Black again allows the light-square repetitions and the draw: 21.Qe6+ Kh7 22.Qf5+ Kg8 23.Qe6+ etc. White, in turn, chooses to fight on – from a worse position. 21.Be5 d3 Black's advancing pawn will soon star in a whole collection of dramas itself, but for now the second player needed to first defend with 21...Qf8. 22.Bxg7 White is beginning to grasp the situation. The text move, indeed, allows a draw after 22...Qg5 23.Qe6+ Kxg7 24.h4 Qc1+ 25.Kh2 Rhg8 26.Rg4+ etc. However, White had more in the position: 22.Qe6+ Kh7 23.Rg4 Qf8 24.Qg6+ Kg8 25.Bxg7 Qf7 26.Qxd3. Black is temporarily a Rook up, but he will shortly need to surrender his Queen. 22...d2 This move should seriously scare White into going for a draw. For a moment, it looks like it does.

23.Qe6+

Okay: Now, after 23...Kxg7 24.Rg4+ Qg5 25.Qd7+ Kf6 26.Rxg5+ hxg5 27.Qxd2 White will have a Queen and a pawn to balance out Black's two Rooks. A complicated, but roughly even, game.

Instead, Black distrusts the passive Bishop sacrifice, and immediately falls into a doomed situation.

23...Kh7 24.Qxh6+ Kg8 25.Qxh8+ There is no need for 25.Qe6+ now. 25...Kf7 26.Rf4+ 26...Ke6 27.Qh6+ Kd7 Now 28.Qh5, guarding against the passed pawn Queening (if 28...Kc8, 29.Rf8) and preparing to finish up the King, looks like the proper reward for White's fighting spirit. Unfortunately, he has a worried eye on Black's passer, and decides that "more checks to the King" is the answer. It is not – but the excitement is hardly over.

28.Rf7+ Kc8 Black can afford to allow his Queen to be pinned to his King: he plans on getting another one. 29.Qe6+ Kb8 30.Kh2 d1Q Black has travelled far from his "doomed situation" mentioned in the note to White's 23rd move. He figures from here on out, it's just a matter of technique.

It is – but it has to be proper technique.

31.Rf8 a6 What was called for was something that ends the clutter, something like 31...Qxf8 32.Bxf8 Qd8. Black's move, however, lets loose the chaos again. White now has the remarkable 32.Qe7, after which, despite being a Queen down, he can enforce the draw, obtain a better position, or checkmate Black: 32...Ka7 ( 32...Qc8 33.Rxc8+ Kxc8 34.Qf8+ Qd8 35.Qf5+ Qd7 ( 35...Kb8 36.Qxc2 +-) 36.Qf8+ Qd8 37.Qf5+ draw) 33.Qc5+ b6 34.Rxd8 Rxd8 35.Qxc7+ Ka8 36.Qc6+ Ka7 37.Qc7+ draw Amazing! 32.Rxd8+ Aquiescing to the loss. Well, not exactly: White still has a handful of "Jerome pawns" and decides to put them to use. Still, thirty moves later White resigned.

Is there any wonder why the Jerome Gambit still fascinates me??

Like a bull in a china shop...



When you know the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) as well as Pete Banks ("blackburne"), you can be dangerous with either the White or the Black pieces. Until they invent Gray pieces (and maybe not even then) no game that includes him is going to be safe.

Haroldlee123 - blackburne
JGTourney4 Chessworld, 2009

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

4...Kxf7 5.0-0

One of the Modern Jerome Gambit variations, in which White limits his sacrifices.

5...d6 6.h3 Nf6 7.d3 Rf8 8.Bd2 Kg8

Black has taken advantage of the "quietness" of the position to castle-by-hand, and even leads in development.

9.Nc3 Nd4 10.Nxd4 Bxd4 11.Rb1 Be6 12.Nb5 Bb6 13.b3 Qd7 14.Nc3 Rf7 15.Qf3 Raf8

Black even plans to make use of the f-file, which White opened for him.

16.Qe2 Bxh3
17.Qf3

Taking the Bishop leads quickly to mate. Now Black wraps the game up with play against the f-pawn.

17...Bg4 18.Qg3 Nh5 19.Qh4 Rxf2 20.Rxf2 Bxf2+ 21.Qxf2 Rxf2 22.Kxf2

22...Qf7+ 23.Kg1 Ng3 White resigned

Against the Semi-Italian

I've been having second thoughts about the accuracy of my strategy against the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) cousin: Jerome-ized play against the Semi-Italian Opening, 1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.0-0 (my choice) Bc5 5.Bxf7+.

Recently, I've collected 138 games which suggest the brute-force method of "no waiting": 4.Bxf7+, anyhow. At first glance, however, that seems a bit blunt to me, even if it's perfectly playable in lightning chess.

So I was happy to receive the following game, from Welton Vaz, (see "Xadrez, Ficção Cientifíca e Paz").

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6


4.c3 Bc5 5.Bxf7+ Kxf7 6.Nxe5+

Just like with the Jerome Gambit proper, there has developed a "modern" treatment of the Jerome-ized Semi-Italian opening, one which does not include 6.Nxe5+. Several games in the current Jerome Gambit Thematic Tournament at Chessworld have developed that theme:

8.Qf5+ Kd6 9.d4 Ne7 Black is surprised, and makes a poor response.

10.dxc5+


This move leads to a winning advantage for White, but next time I am sure that Ghandy will take the simpler 10.Qxe5+ Kc6 11.Qxc5#.

10...Kxc5 11.Qxe5+ Kc6
White is up a pawn, but, more importantly, Black's King is not safe.

12.Be3 d6 13.Qd4 Bg4 14.Qa4+ b5 15.Qa6+ Kd7 16.Qxb5+ c6 17.Qd3

Black has some open lines (that he has purchased with his pawns) which he can place his Rooks on, but they are not adequate compensation.

17...d5 18.f3 Bh5 19.Na3 Kc7 20.Qa6 dxe4 21.Rd1 Qb8 22.Nc4


White's position is so overwhelming, he even had Bf4 on this move or the next. Instead, he captures more of Black's army, and that works just fine.
22...exf3 23.Qa5+ Kc8 24.Nd6+ Kd7 25.Nf7+ Ke8 26.Nxh8 fxg2 27.Qxh5+


Now Black has some hope of hanging on a bit longer with 27...g6, but decides instead to end it all quickly.

Race to the Finish


With 80% (169 out of 210) of the games in the 15-player, double-round robin Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) Thematic Tournament at ChessWorld completed, the Jerome Gambit has scored 37%.

Piratepaul (19 points out of 23 games completed) maintains his lead. DREWBEAR 63 (17 points out of 28 games), who had been first throughout most of the play, was the first to complete his games; and shares second place with Sir Osis of the Liver (17 points out of 26 games completed).

Sitting behind them are GladtoMateYou (14 points out of 24 games), then blackburne and eddie43 (13.5 points out of 26 games), and stampyshortlegs (13 points out of 17 games).

Only one player, because of the number of games he has yet to complete, has a statistical chance of topping Piratepaul's (current) 19 points: stampyshortlegs (maximum score possible - 24).

From a practical point of view, it looks like it will be a race between Piratepaul (maximum score possible - 24) and stampyshortlegs for top honors.

More Tactics

For those who believe that chess is "99% tactics", and this is especially true for those who play the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), very often one lives by the tactic, and dies by the tactic...

Here are three more examples (a bit more challenging) from the current Chessworld Jerome Gambit Thematic tournament.

DREWBEAR 63 - GladtoMateYou
JGTourney4 ChessWorld, 2009


Despite being the extra piece up that the Jerome Gambit defender often receives, Black finds that his King has wandered into a mating net. If he keeps his wits about him, though, he can still split the point.

Black had to try 30...Nxc4 31.Kxc4 Bd5+ 32.Rxd5 cxd5+ 33.Kxd5 Rxg7 when White, down the exchange, does best to force a draw by repetition: 34.Ra3+ Kxb5 35.Nd4+ Kb4 36.Nc2+ Kb5 37.Nd4+ draw

Instead, Black walked right "into it"

30...Ka4 31.Ra3 checkmate



Black Puma - Haroldlee123
JGTourney4 ChessWorld, 2009



In this complicated position, Black holds the Jerome advantage of a piece for two pawns, but his development is a bit haphazard, and he needs to be careful. Troubling tactics lie right beneath the surface, and he should play 35...Nxg5 with a chance to settle things down a bit. Instead, he plays a very reasonable move, and receives a shock.

35...Rh8 36.g6 Kxg6 37.Nh4+ Kf6 38.Nf5 Qf7 39.Rh6+ Qg6 40.Rxg6+ Kf7 41.Rg7+ Black resigned



DREWBEAR 63 - TWODOGS
JGTourney4 ChessWorld, 2009

In this position, seeing that he was losing his Queen for a Rook, White resigned.

Instead, he could have tried 33.Nb5 Qxb2+ 34.Rxb2 Rxb7 35.Kxc4 a6 36.a4 axb5+ 37.axb5 with at least equal chances.
