We must know what we're doing...


Did you look over the games from Thursday's post?

Did you actually play the moves from Bill Wall's games out in your head or on a board?

Did you wind up asking yourself: What was Black thinking??

White plays 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 and before he can even think of sacrificing his Bishop with 4.Bxf7+ he sacrifices his Knight instead with 4.Nxe5.

Does Black say "Yippee! Gimme! Gimme!ThankYouVeryMuch!" and take the piece? No, he does not. He looks the gift horse in the mouth and plays 4...Nh6

Really.

Next time around, the Bill's new opponent does take the Knight, but only after he sacrifices a piece of his own with 4...Bxf2+ 5.Kxf2 Nxe5.

What?

If these were over-the-board games, we might be accusing Bill of witchcraft  or would that be warlockcraft ?

Every time I tell Bill that it's risky to play such a refuted opening as the Jerome Gambit, he reminds me that it is only risky if the opponent knows the refutation.

Sometimes, instead, the opponent figures that the Jerome Gambiteer must know what he's doing – why else would someone sacrifice a piece, except if it were strong ? –  and so bails out of the refutation, just in case.

With almost 1600 posts, this blog is many things, but most peculiarly an ongoing study of what must be considered errors in problem-solving.

Never Say "Never"



After introducing the mangled-Jerome-Gambit line 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Nxe5 from a game by MrJoker in "Why So Serious?", with a caution not to try out White's move (premature in the Jerome), I almost immediately had to post Bill Wall's interest in investigating where angels fear to tread, so to speak (see "Relatively Speaking").

Who could be surprised by the following email I just received?

(I love working on this blog!)

Rick,
 
After Joker recommended not to play 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Nxe5, I decided 
to take the challenge and play it. I am glad to see that there are 130 games of this variation 
in the ChessBase Big Database 2012. Here are two more to add to the collection.
 
Wall - Guest2075193, www.playchess.com, Nov 10, 2012
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Nxe5 (instead of Jerome's move with 4.Bxf7!?) 4...Nh6 
(most common and better is 5.Nxe5) 5.Qh5 (may be a new move. Previously played has 
been 5.Ng4) 5...O-O? (doesn't look good. Best seems 5...Qf6, threatening 6...Qxf2+) 
6.Nxc6 Bxf2+ (6...bxc6 7.Qxc5) 7.Kxf2 dxc6 (now Black threatens 8...Qd4+ and 9...Qxc4)8.d3 Bg4 
(perhaps 8...Ng4+) 9.Qc5 Qh4+ 10.Kf1 (or 10.g3) 10...Kh8? 11.Bg5 Qh5 
12.Be7 Rfe8 13.Qxh5 Bxh5 14.Bg5 Ng8 15.Nd2 b5 16.Bb3 h6 17.Bf4 Re7 18.h3 g5 
19.Be3 a5 20.g4 Bg6 21.a4 Kh7 22.h4 and Black resigned 1-0

8.d4 N5g6 9.Nc3 c6? (9...O-O) 10.e5 Qh4?? (White now traps the queen. Perhaps 
10...Nxe5 11.dxe5 Qxe5. Not 10...Qf5? 11.Bg4. 10...Qe6 11.Ne4 looks good for White)

Relatively Speaking


No sooner had I posted a game by MrJoker (a player with years of experience with the Jerome Gambit) giving a warning not to follow up 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 with 4.Nxe5, than I received an email from Bill Wall (another very successful Jerome Gambiteer), wondering if the move should be avoided, after all...

It took me a while to understand his point, at which time I cracked up laughing.


There are 33 possible moves that White can play in this Italian Game position. On a blog that has examined and championed the arguably 28th worst* of those choices, I had been skeptical about someone talking a look at the 27th worst move!

A lot of 4th moves for White are "playable" in this position if they are compared against Alonzo Wheeler Jerome's favorite, rather than against the "best" move.

Readers might want to uncover the 5 moves "objectively" worse than 4.Bxf7+.

Act Hastily, Repent at Leisure




perrypawnpusher - joseluizlopez, blitz, FICS, 2012


In a recent Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) I was generally out-played by my opponent, and, for some reason, decided that I should take refuge in a pawn-down endgame – which you can see, from the above position from the game, turned out to be not a very successful strategy.

I played on because my opponent was short of time, and I foolishly hoped that his flag would fall before my King did.

To speed things up, I had been using the "pre-move" function at FICS, where you can chose your next move while your opponent is thinking, and the computer will immediately execute it as soon as it is your turn. Save seconds, put on the pressure...

In certain circumstances, that can be an effective tactic, but look what happened in this game: 

49...Qb5??

This has to be a mouse slip for 49...Qb4

Black throws his Queen away and – lucky for him – his King's good position allows him to sheepishly draw.

But, I looked on in horror, as I had never imagined that my opponent would have come up with this blunder, and I had already pre-moved something different...

50.Ka3????

And I was checkmated a few moves later.

Why so serious?




I recently received an email and game from Louis Morin, aka MrJoker. Playing through the game, I got very nervous after White's 4th move, but as I played on I imagined that I could hear Heath Ledger's voice as the Joker "Why so serious?"

Indeed, despite the difficulties, MrJoker wrapped up the game like it was an amusing anecdote.

Hi Rick

Perhaps my most recent game on ICC could be of interest for your blog.


MrJoker - HarryP
Internet Chess Club, 2012

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Nxe5?? 


Okay I am joker but not usually that much... 

4...Nxe5 

Only now did I realize that I forgot to play Bxf7+ before Nxe5+.
I am getting old I guess… 

5.Qh5 Qf6 6.0-0 g6 7.Bxf7+?? 


Never too late? 

7...Kxf7 

I must admit that I completely overlooked this. I thought Black had to take with the Queen or Knight. Now I have a typical Jerome gambit position… except for the fact that I am 2 full pieces down instead of “only” one. Anyway, White’s advantage is still decisive, it will only take a bit longer than usual to realize it.

8.Qe2 d6 9.Kh1 Ne7 10.c3 N5c6 11.d4 Bb6 12.Bh6 Qh4 13.Qe3 Ne5 14.Bg5 

14...Qxh2+ 15.Kxh2 Ng4+ 16.Kg3 Nxe3 17.fxe3+ Ke6 18.Rf6+ Kd7 19.Rf7 Re8 20.Nd2 c6 21.Raf1 Bd8 


22.Rxh7 Kc7 23.Rff7 Kb6 24.Bxe7 Be6 25.Bxd8+ Raxd8 26.Rxb7+ Ka6 27.Rxa7+ Kb6 28.Rhb7 checkmate


I hope you enjoyed this. But if you publish this game, tell your readers I advise them NOT to try 4.Nxe5.

Proto-Jerome Gambits? (Part 5)


As a last look at the possible influences on Alonzo Wheeler Jerome, in his creation of 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+, we take a look at the line 1.e4 e5 2.d4 exd4 3.Bc4 Nf6 (instead of 3...Bc5) which transposes, after 4.Nf3, to the Urusov Gambit, which is deeply covered at Michael Goeller's wonderful site.

While the 1857 analysis of the gambit by Prince Sergei Urusov may not have been available to AWJ, games like Kolisch - Paulsen, London, 1861, might have been.

It is hard to get very Jerome-ish here, after 4...Bc5, but Goeller does mention the modern game Hopf - Schintgen, Bratislava 1993, which continued 5.e5 Ng4 6.Bxf7+ (1-0, 34).

(Of course, if, instead, Black plays 4...Nc6, then after 5.0-0 Bc5 6.e5 Ng4 ["playable but rarely seen" according to coverage at Chessville.com] then 7.Bxf7+ would come in a Max Lange Variation of the Two Knights Defense, which is a whole 'nother thing...)

Proto-Jerome Gambits? (Part 4)


Of course, as Alonzo Wheeler Jerome was putting together his ideas on the Jerome Gambit, he might well have been influenced by the games of Joseph Henry Blackburne, whose aggression often showed up in sharp attacks like the one after 1.e4 e5 2.d4 exd4 3.Bc4 Bc5 4.Bxf7+ as we have seen before; or, a move later, here.

(A correspondence game played after Jerome passed on is still worth passing along again.)

Coming out of the move order that we have been looking at, 1.e4 e5 2.Bc4 Bc5 3.d4 exd4 the Lewis Gambit, reaches the same position after 4.Bxf7+, and, as the earliest example was Staunton - Cochrane, match, 1841, the line was likely available to Jerome as well. 

It is also available to Readers who would like to check out Secrets of Opening Surprises, Volume 10, edited by Jeroen Bosch, where the Lewis Gambit is examined.

Proto-Jerome Gambits? (Part 3)


Of course, as Alonzo Wheeler Jerome was developing his Jerome Gambit (1.e4 e4 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) there is always the possibility that he was influenced by the games of the Italian chessplayer Gioachino Greco (c. 1600 – c. 1634), who started off his own gambit with 1.e4 e5 2.Bc4 Bc5 3.Qe2, with the possibility of 3...Nf6 4.Bxf7+ followed by 5.Qc4+ picking up the Bishop on c5. 

Actually his idea was to follow up with 4.f4.

The idea of Qe2 for White in the Jerome Gambit has shown up in a number of games, however. See: "Home Cooking" for one set of examples, and "Adolf Albin Plays the Jerome Gambit (Part 1)" and "(Part 2)" for another interesting game. Of course, there are any number of games by Bill Wall, including this one.

Proto-Jerome Gambits? (Part 2)


Although there is no record, it is quite likely that Alonzo Wheeler Jerome played chess during his time as a soldier during the American Civil War, and he may even have developed his gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) then.

It is also quite possible that Jerome encountered (or played) what is now known as the "Scholar's Mate", 1.e4 e5 2.Bc4 Bc5 3.Qh5, with a look toward 4.Qxf7#; although he may have known it at the time as the Kentucky Opening (see "Kentucky Opening" Part 1, Part 2, Part 3 and Part 4 as well as "The Kentucky / Danvers Opening").

Following the Kentucky, if Black defended with 3...Qe7, White would still have the gambit 4.Bxf7+ Qxf7 5.Qxe5+, winning two pawns for the piece, as in the Jerome. The difficulty with this line, however, is that Black can answer with 5...Qe7, and after the exchange of Queens Black's King can still castle to safety. 

In casual  or club play, someone more skilled with pawns than his opponent was skilled with piece play might still be able to hold on with White; but one can already see, as AWJ may well have, that the Jerome Gambit would, at least in one way, be an "improved Kentucky Opening".

Proto-Jerome Gambits? (Part 1)


Alonzo Wheeler Jerome, as far as I have been able to determine, did not leave an indication as to what openings inspired him to develop 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+.

Certainly one of the first possible lines that could have caught his eye was in the old Bishop's Opening symmetrical variation: 1.e4 e5 2.Bc4 Bc5 3.Bxf7+.

Some sources refer to this line, too, as the Jerome Gambit, although they must be relying on the Bxf7+ trope, as there is no indication (yet turned up) that AWJ played the Bishop's Opening version of his "Double Gambit". I have elsewhere referred to it as the "Abrahams Jerome Gambit".

Not that the line doesn't have some bite...

Coffeehouse Chess Videos


David Kane (Kuasm) has started a series of "Coffeehouse Chess" videos at YouTube, focusing upon openings that are dodgy and dubious, showing refutations and then basic ideas, for those who want to play the lines for fun or in casual chess.

So far he has covered the Englund Gambit (1.d4 e5) and the Blackburne Shilling Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc3 Nd4). They are certainly worth viewing.

He has said that he will look at the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+). I am especially looking forward to this one.

I am thrilled!



Yuri Bukayev has a very funny sense of humor. He recently sent me this email:

I found super news for you! Thus, I found on WGM Olympic Champion 2012 N. Pogonina's site (section "Press", publication "Natalia Pogonina Interviewed by Chess Rex", 30.07.2012) the following piece:

Chess Rex: If in chess… all pawns became bishops… then what would be the problem in playing the game? Or who will get the advantage…White or Black? If you are playing such game as white, then what would be your first move and why?

Natalia: This “game” is a mate in 4: 1.Bxf7+ Kxf7 2.Bc4+ (or 2.Bh5+) Ke8 3.Qh5+ Bg6 4.Qxg6# There are a few sub-variations (exercise: find them), but it’s still a mate in 4.

Thus, dear Rick, the Jerome Attack is theoretically the strongest opening, a winning opening, if... 

Are you glad?

Rocket Surgery 2.0



The last time that I played MrMef (see "Rocket Surgery") we developed a game that was truly a mess... This time I seriously wanted to get it right.

perrypawnpusher - MrMef
blitz, FICS, 2012

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 h6 5.0-0 Bc5 6.Bxf7+ 




The Semi-Italian Four Knights Jerome Gambit.

6...Kxf7 7.Nxe5+ Nxe5 8.d4 Bxd4 9.Qxd4 Nc6



Attack the Queen is Black's notion. My response was based on the naive notion (although it has proven successful in past games) that Black might want to continue to harass Her Majesty with the erronious 10...Nb4.

10.Qd3 

Probably better was 10.Qc4+

10...Ne5

Chasing the Queen to a better spot.

11.Qg3 d6 12.f4 Nc6 13.Bd2 Qe8 



Black is taking steps against the threatened e4-e5 by White, but I think that his Rook needed to be doing this. That would also be preparation for castling-by-hand.

14.Rae1 Bg4 

 Black has made a series of small mistakes, and before this puzzling move the cost has been, at most, allowing White to claim (because of his development) a nearly equal game. Now the first player gets his attack on.

15.e5 dxe5 16.fxe5 Nxe5 



I am not sure if this is an oversight or a miscalculation. Did my opponent not see that my Queen strikes at e5, or was he, perhaps, expecting to see 17.Qxe5 Qxe5 18.Rxe5 Rhe8 with an even game?

17.Rxe5

Of course.

17...Qd8 18.Rd5 

I avoided the better 18.Qxg4 because of 18...Qxd2, but after the game Houdini pointed out that 19.Qe6+ Kg6 20.Rd5 would trap the Black Queen, i.e. 20...Rad8 (20...Qxc2 21.Rxf6+ gxf6 22.Qg4+ Kf7 23.Rd7+ Kf8 24.Qg7+ Ke8 25.Qf7#) 21.Rxd2 Rxd2. 

18...Qe7 19.Re5 

19...Qd6

It may look at first that Black would have done better by withdrawing his Bishop to shield the Queen, but after the game Houdini found that that led to a mate in 25: 19...Be6 20.Nd5 Qc5+ 21.Be3 Qd6 22.Nxf6 gxf6 23.Bc5 Qd7 24.Qf3 f5 25.Rd1 Qc8 26.Rde1 h5 27.c4 Rh6 28.Rxe6 Qxe6 29.Rxe6 Rxe6 30.Qxh5+ Kg7 31.Qg5+ Kf7 32.Qxf5+ Rf6 33.Qh7+ Ke6 34.Qe7+ Kf5 35.g4+ Kg6 36.Bd4 Raf8 37.h4 a6 38.h5+ Kg5 39.Bxf6+ Rxf6 40.h6 Kf4 41.Qxf6+ Ke3 42.h7 Kd2 43.Qf5 Kd1 44.h8Q c5 45.Qf1+ Kd2 46.Qc3#

Totally ridiculous, but it does show that White's attack is powerful. 

20.Ne4 Qd4+ 21.Be3 

21...Qxb2 

Instead, 21...Qd7 would have provided a modicum of defense, although White's attack would cost Black significant material.

22.Nxf6 gxf6 23.Qf4

I was pretty sure that the Rook sac at f6 worked, but I couldn't figure it all out in my head until after the game: 23.Rxf6+ Kxf6 24.Qf4+ Kg6 25.Qxg4+ Kf6 26.Qf5+ Kg7 27.Re7+ Kg8 28.Qf7# 

Pity. Bill Wall would not have missed that.

23...f5 

24.Rxf5+ Bxf5 25.Qxf5+ Ke8 26.Qe6+ Kd8 27.Rd1+ Black resigned

Comeuppance


I have faced a number of defenders who fought back against the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 4.Bc4 Bc5 4.Bxf7+) by putting their light-squared Bishop on b7 and putting one or two Rooks on the g-file. My success made me lazy in the following game, and the result was not hard to predict.

perrypawnpusher - xxfred
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 Neg4 



The nice thing about being two pieces ahead is that you have many choices on how to give one back.

8.dxc5 d6 

Black has played a number of alternatives, the first shown here being a bit too exotic:

8...Nxf2 9.Kxf2 Rf8 10.Rf1 Kg8 11.Kg1 d6 12.Bg5 dxc5 13.e5 h6 14.Qxd8 Rxd8 15.exf6 hxg5 16.fxg7 Kxg7 17.Ne4 Bf5 18.Nxc5 Bxc2 19.Ne6+ Kg6 20.Nxd8 Rxd8 21.Rac1 Rd2 22.Rf2 Rxf2 23.Kxf2 Be4 24.Rxc7 a5 25.Rc4 Bd5 26.Ra4 b6 27.b4 axb4 28.Rxb4 Bxa2 29.Rxb6+ Kh5 30.h3 Bd5 31.Rb5 Bc4 32.Rc5 Be6 33.Re5 Bc4 34.Re4 Bd5 35.Rd4 Bc6 36.g3 Be8 37.h4 gxh4 38.Rxh4+ Kg5 39.Kf3 Bc6+ 40.Kf2 Bd5 41.Rd4 Bc6 42.Rc4 Bd7 43.Kf3 Bc6+ 44.Ke3 Bb5 45.Rf4 Bc6 46.Kd4 Bg2 47.Kc5 Ba8 48.Kd6 Bb7 49.Ke5 Bc6 50.Rb4 Bf3 51.Rf4 Bd1 52.Rf5+ Kg4 53.Rf1 Bf3 54.Rg1 Bd1 55.Kd4 Bf3 56.Ke3 Bc6 57.Kf2 Bd5 58.Rd1 Bc6 59.Rd4+ Kg5 60.Ke3 Bb7 61.Rb4 Bc6 62.Rb6 Bd7 63.Rd6 Bb5 64.Rd5+ Kg4 65.Rxb5 Kxg3 66.Rb4 Kg2 67.Kd2 Kf3 68.Ke1 Ke3 69.Rb5 Kd4 70.Rb4+ Black forfeited on time, yorgos - mikheilmikeladze, FICS, 2009;

8...Qe8 9.Bf4 Nxe4 10.Qd5+ Kf8 11.Qxe4 Qxe4+ 12.Nxe4 d5 13.cxd6 cxd6 14.Nxd6 Be6 15.f3 Nf6 16.0-0-0 Ke7 17.Nxb7 Bxa2 18.Rhe1+ Kf7 19.b3 Rac8 20.Nd6+ Black resigned, Wall,B - Kaiser, Chess.com, 2010; and

8...Qe7 9.0-0 Qe5 10.b4 Qxh2 checkmate, stretto - HunterCuinn, FICS, 2008

9.cxd6 cxd6 10.0-0 Re8 11.Bg5 Kg8 12.h3 Ne5 13.Qd4 Rf8 



Missing a chance for the tactical pawn grab: 13...Bxh3 (if 14.gxh3 Nf3+).

14.Rad1 Nf7 15.Bxf6 Qxf6 16.Qxf6 gxf6 17.Nb5 Rb8 18.Nxd6 Nxd6 19.Rxd6 Kh8 

White has three pawns for his sacrificed piece, and the game looks about even.

20.Rfd1 Rg8 21.Kh2 f5 22.e5 b6 23.Rf6 Rb7 24.f4 



A complete misunderstanding of the needs of the position. White's g-pawn is going to take a lot of heat. Black, too, can attack in the Jerome Gambit!

24...Rbg7 25.Rd2

Better 25.Rg1

25...Bb7 26.Rxf5


Suicide.


26...Rxg2+ 27.Rxg2 Rxg2+ 28.Kh1 Rg5+ White resigned

In my post "On the Other Hand..." the other day, I mentioned Abby Marshall's "The Openings Explained" column at ChessCafe, where she recently took on "The Two Knights Defense, Center Fork Trick" (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Nxe4 5.Nxe4 d5)

I also alluded to Yury V. Bukayev's analysis as well, which I sent to Abby.

Ms. Marshall had selected and added my email to the bottom of her column as "pertinent response."

Rick Kennedy from the USA – Abby, I never miss your column at ChessCafe, and love the hard work you put into each one. Here's an interesting Fork Trick resource. Please keep up the great work.

Not Worth One's Full Attention



Most players, if they are aware of the Jerome Gambit at all, remember something about J.H. Blackburne destroying it in a wonderful miniature ending with a Queen sac and mate.

We've discussed the topic before: what if you only remember parts of Blackburne's counter-attack?

After all, the Jerome isn't really worth the defender's full attention, especially in a blitz game, is it?

perrypawnpusher -NN
blitz, FICS, 2012

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 Bd6 



Okay, okay, Blackburne actually played 7...d6 here, but perhaps my opponent was thinking of an "improved Blackburne Defense"? 

(Actually, in The Database Black scored 9% in 32 games, so it's not really much of an improvement.)

8.Qxh8 Nf6 

I'm pretty sure that Blackburne trapped White's Queen with this move...

9.Qxd8 Black resigned



Sure, an example of taking advantage of my opponent's distractedness. Still, this is the fifth example of such a Queen "sacrifice" in The Database, so I have to encourage readers: the next time your opponent looks at your opening disdainfully and says "I have half a mind to..." – say Thank you!

On the Other Hand...


When I wander over to the ChessCafe website, I like to read the monthly column by Abby Marshall (USCF Candidate Master, currently rated 2192) "The Openings Explained". She's a hard worker, she's not afraid of playing gambits (the King's Gambit is her specialty) – and she used to be from my home town.

This week's topic is "The Two Knights Defense, Center Fork Trick" [1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Nxe4 5.Nxe4 d5], something that has been discussed on this blog a number of times before (like when you play 1.e4 e5 2.Nf3 Nc6 3.Bc4 looking for a Jerome, and your opponent plays 3...Nf6; can your 4.Nc3 get him to cough up 4...Bc5, so you can play 5.Bxf7+ ?). For just a sample of posts, try "Jerome Gambit vs Two Knights Defense (Part 3)" and "Further Explorations (Part 1 and Part 2)"

Don't forget to review Yury V. Bukayev's analysis as well, which I will be sending to Abby.

Pawn Stars



Just saw a reference to the television show "Pawn Stars".

I checked it out right away!

Man, was I disappointed...

It's not AT ALL about chess.

Anomaly


Intrigued by yesterday's Jerome Gambit Declined (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kf8/Ke7) game (see "Tumbling Dice"), I thought I'd take a look at the line in The Database and see what up-to-date data I could drum up.

I was surprised to see that White, ahead a pawn and having prevented Black from castling, only scores 58% in 238 games. Admittedly, that's better for White than the straight Jerome Gambit line  44% in 8,737 games  but it still seems light.

(Perhaps one must take into account the level of play, and Geoff Chandler's "blunder table".)

Breaking it down was not much help.

In 205 games, when Black declined the Bishop sacrifice with 5...Kf8, White scored 57%. Immediately removing the White Bishop from danger or exchanging it off  what would appear to be the simplest and best plan for the first player  did not matter a whole lot. In 51 games White played 6.Bxg8, scoring 63%. This was better than the 25 games in which White played 6.Bb3, scoring 56%; and the 18 games where White played 6.Bc4, scoring 53%. However, only one of those percentages is an improvement on the core 57%.

(We seem to have hit another one of those Jerome Gambit anomalies: by playing a "worse" line, White, apparently, scores "better" – or at least not any worse.

In the 33 games where Black played 5...Ke7, however, White scored 71%. That should be an indication for Black – although accepting the Bishop with 4...Kxf7 remains the best idea.

Tumbling Dice



I was looking for a recent example of the Jerome Gambit Declined, a rather rare beast, when I ran across a game by an upstanding member of the Jerome Gambit Gemeinde, HauntedKnight. 

The following game, however, takes on the look of some tumbling dice, as the fortunes of both players change widely. However, as we have seen recently ("Wonderland"), White's "secret weapon" (i.e. it can take time for Black to figure what is going on in the Jerome, and how to play against it) finally snatches victory from the jaws of defeat. Bwa-ha-ha-ha-ha!


Congrats, HK, a win is a win.

Reflectogen

Readers know that I have encouraged those interested in new cutting-edge chess opening theory, and chess improvement in general, to visit Bruno's Chess Problem of the Day (see "Bruno's Chess Opening Articles" on my list of links). 

For some educational examples, see: "A New Link", "Improve Your Chess", "Something New in Something Old", "Even in the Most Respectable of Settings" and "Update".

The latest entry concerns 1.e4 e5 2.d3 Bc5 3.Nc3 Nf6 4.Nf3! known as the Nf3-Bukayev gambit-reflectogen.

Wonderland


Sometimes a defender, having wandered into the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), feels out of place, as things are not quite what was expected, as if it's a trip to Wonderland...

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Ke7 



The earliest example I have of this move (which might as well be called the "buyer's regret" variation) in The Database (with the addition of my game, White has scored 89% in 23 games) is SirOops - mentalGIANT, standard, FICS, 2001 (1-0, 25); although it certainly must have been played over-the-board earlier.

8.Qxe5+ Kf7 9.Qxc5

Surprisingly, I missed playing my usual "nudge" 9.Qd5+, driving the King to the back line to interfere with the Rook. 

9...Nf6 10.Nc3 d6 

White is up two pawns, and it is hard to see Black's compensation.

11.Qe3 

Probably not best, given that it leaves White's Queen and King on the same file that Black's Rook can quickly go to. Nothing bad happens, as a result, but this reinforces the point that White should have "nudged" when he had the chance.

11...Rf8

Black prudently castles-by-hand. After the game Rybka suggested the wild 11...d5 12.Qf4 g5!? 13.Qg3 (13.Qxg5 Rg8 14.Qf4 Rg4 15.Qe5 dxe4 16.0-0) 13...dxe4  to reduce White's advantage.


12.0-0 Kg8 13.d4 b6 14.f4 Bb7 15.e5 Re8 




16.Qd3 Ng4 17.Qg3 

Or 17.h3 as Rybka later suggested.

17...Bc8 18.f5 dxe5 19.Qxg4 exd4 



20.Bh6 

Missing the better 20.Ne4

20...Qf6 21.Bg5 Qc6 22.Nd1 Black forfeited on time
