More to the Point...


[continuing the imaginary discussion of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) started yesterday with "It's hard to explain..."]

Explanations for any success of the Jerome Gambit (and there are players like Bill Wall who score 95%+ with it) must be found in the  blitz and casual practice of club chess players, not the international tournaments of masters or grandmasters.

That now seems obvious. "The masters, they are different", right?

More important is the way in which club players are different. A good example is Geoff Chandler's fanciful "Blunder Table" which, when the laughter is done, contains a lot of chess truth. Chandler suggests that in a game between players rated over 2000, the loss of a pawn should be enough to decide the outcome. For players rated around 1800, a couple of pawns would be the winning advantage. For a game between two 1500 players, however, an extra Bishop or Knight would be necessary to "guarantee" one side a win.

[Blush] [Silence] [Drumming of fingers]

In many Jerome Gambit games, White has given up a piece for two pawns – the equivalent of spending about a pawn to get to the kind of positions that he is comfortable with, and his opponent, far more likely than not, is not. That amounts to "suicide" among masters, but "unclear" among many club players.

True, but can't Black take the time to settle himself down and work out a defense?

Of course, and the stronger the defender, the more likely that is to happen. In blitz games, however, that will cost time. And in casual games, it will require attention.


Delaying, but not eliminating the "blunder bomb"?

Exactly. Also, some "advantages" are easier for club players to take advantage of, while some are more challenging. For example, which would you rather have, an extra piece, or an extra two or three pawns?

Well, it depends, doesn't it?

It almost always "depends", yes, but, remember, it is the Jerome Gambiteer choosing when such a thing happens. I have seen hundreds of games where White advances his two "Jerome pawns" against Black's position, and the "logical" outcome – instead of allowing his position to become fatally cramped or dangerously opened up via pawn exchanges – should be that the defender "simply" returning the extra piece for the foot soldiers, with at least an even game. But it rarely happens.

Sometimes returning the extra piece is anything but simple.

Ah, so I see that you have tumbled to the Jerome Gambit as well, eh?

Perhaps we can continue this discussion another time...

It's hard to explain...


Often I find myself explaining the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) to people in conversations that go something like this...

So, this Jerome Gambit thing, it must be some kind of great opening that wins all the time?

Well, actually, it's known as the "worst chess opening ever".

Oh... It must make you feel sad, losing all the time with it.

In truth, I win more than 3/4 the time. Maybe, 80 - 85%.

Aha! Beating up on all those weakies, I imagine!

Sometimes I give "Jerome Gambit odds" to players weaker than me, to even things up. Sometimes I play above my head, too. Looking at the strength of my opponents, I should score maybe 60%.

But you score 80% or more? What's THAT all about?

Members of the Jerome Gambit Gemeinde become experienced in the field of "the psychology of error".


Please explain.

The simplest idea is "the ticking time bomb". Willy Hendriks explains something like it in his Move First, Think Later: Sense and Nonsense in Improving Your Chess, only, of course much better than I do. Basically, stronger players err less often than weaker players.

Duh.

Think of each player having a ticking time bomb that goes off whenever he or she makes an error. Grandmaster "booms" are relatively infrequent. Beginning player "booms" are much more frequent, like a series on a snare drum.

Or ticks of a clock?

In some cases, yes. Anyhow, even after the Jerome Gambiteer has presented an opponent with the gift of a "won" position, if White can use an understanding of the tactics and strategy of the opening to delay further "booms" on that side of the board, the opponent will have a chance to chime in.

"Boom" and the game is even?

Yes, and sometimes "boom" again, and White has the advantage. Or, sometimes it's simply "boom" and White wins.

That doesn't seem like "real" chess.

Well, Grandmasters would never play the Jerome Gambit, right, but there is much truth in Andy Soltis's book Catalog of Chess Mistakes when he points out the large number of games (especially at the club level) that are "lost" rather than "won".

Ouch. What else is involved in "the psychology of error"?

There is a whole lot more. For example...

Not This Time

rego - zille, blitz, FICS, 2012
How often have we seen White, in the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), escape into the safety of a Bishops-of-opposite-colors endgame, even down material?

Or see White use his endgame experience in those bits of murkiness to out-play his opponent in an "objectively" equal game?

Alas, this time White found no slight-of-hand available, and agreed to split the point. Pity. Perhaps the clock was ticking down, after all...

Upon Closer Examination

ethanaaron - KlassAct, standard, FICS, 2012

In the above diagram, from a recent Jerome Gambit game, we can see that Black's pieces are active and that he is a piece ahead. 

Upon closer examination, however, it appears that White can simply advance his Queen, and then take back the piece on the following move.

The game continued:

31.Qe7

Threatening the Bishop.

"No problem," thinks Black. "There is a defense to that nasty Queen!"

31...R2-c7

However, after

32.Rd8+ Rxd8 Black resigned


It is suddenly clear that White will collect three pieces (33.Qxd8+ Kf7 34.Qxc7+ and 35.Qxb7) and be a Rook ahead.

Black should have tried something like 31...Qc5 or 31...h6, after which White would have snapped off the Bishop with 32.Qxb7 with a roughly equal game.

Just throw anything at them...



The nice thing about defending against the Jerome Gambit and its relatives is that you can defeat them by just throwing anything at them. I mean, just throw something, right? Anything?? Right???

geojim - sickduck
blitz, FICS, 2012

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.0-0 Na5 


Here we have geojim, rated about 350 points below his opponent, looking for a really quiet Giuoco Piano, when his opponent decides to mix things up in a blitz game.

Sure, White can now play 5.Nxe5 with advantage, but what if he wanted to be just as snarky as his opponent?

5.Bxf7+ 

Ah, yes, the "Jerome treatment."

5...Kxf7 6.Nxe5+ Ke8 7.d4 Bd6 


8.Qh5+ Kf8 9.Qf7 checkmate


It's a sad, sad day when you have to take a foolish opening seriously.

Stormy


Here is the latest Jerome Gambit from Bill Wall. (Notes by Bill, unless otherwise indicated.) It features a Kingside pawn storm that proves to be Black's undoing.

Wall,B - Guest154187 
Playchess.com, 2012

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 



7.Qd5+ Kf8 8.Qxc5+ d6 9.Qe3 Nf6 




10.0-0 Kg8 

[This move seems to be a "TN", somewhere between the 10...h6 of Wall - LC, Chess.com, 2012 (1-0, 20) and the 10...Kf7 of Wall - Vijay, Chess.com, 2010 (1-0, 22) - Rick]

11.Qb3+ Kf8 12.d3 Ne5 13.f4 Neg4?! 



Better seems 13...Nc6

14.h3 Nh6 15.f5 Qe7 16.g4 Nf7 17.Nc3 c6 18.g5 Nh5 19.g6 Ne5


19...Nd8 looks stronger. White cannot penetrate yet.

20.d4 Qh4?

Black tries for counterplay, but he should defend with 20...hxg6 21.dxe5 dxe5 22.fxg6+ Nf6.

21.Ne2

To stop the 21...Qg3+ threat.  

If 21.dxe5?? then 21...Qg3+ 22.Kh1 Qxh3+ 23.Kg1 Qg3+ 24.Kh1 hxg6 threatening 25...Nf4 mate

21...Ng3? 

Not 21...Nd7?? 22.Qf7#

Best is 21...Nc4 22.Qxc4 hxg6 23.fxg6+ Ke8 24.Qf7+ Kd8 25.Bf4 and White should be slightly better. 

22.Nxg3  and Black runs out of good moves and resigns. 


He could play 22...Nc4, but now White plays 23.Rf3 and wins and not 23.Qxc4?? Qxg3+ 24.Kh1 Qxh3+ 25.Qg3+ 26.Kh1 hxg6+ and Black mates.

Play 'em Like You Got 'em


I have been playing through a number of recent miniatures played by majorminor at FICS (he has over 100 games in The  Database, going back to 2005).

Sometimes he outplays his (often higher-rated) opponent, sometimes he seemingly scares him to death.

Two examples:

majorminor - srff 
rated standard game, FICS, 2012
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.d4 exd4 6.0-0 Nf6 7.Ng5+ Kg8 8.c3 d6 9.Qb3+ Kf8 10.Qf7 checkmate




majorminor - FatTiger
rated standard game, FICS, 2012
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.d4 exd4 6.Ng5+ Ke8 7.0-0 Nf6 8.e5 Nxe5 9.Re1 Black resigned
