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

Poor, Poor Computer

If I told you that an online player recently challenged a computer (rated about 350 points higher than himself) to a game of chess, choosing to play an often-refuted opening and facing its best-known defense (highlighted in a brutal miniature by a master known as "the Black Death") – well, you might be inclined to say "Poor, poor human."

Oh, but you noticed: this post is titled "Poor, Poor Computer" (my emphasis).

Welcome to the weird and wonderful world of the Jerome Gambit! 

radicalmove - LuigiBot
rated standard game, FICS, 2012

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 d6 

Blackburne's Defense, made famous by the game Amateur - Blackburne, London, 1885. See "Flaws (Part I) and Flaws (Part II)".

8.Qxh8 Qh4 9.0-0 Nf6 10.Qd8 

White's 10th move was suggested shortly after the Blackburne game was played, but it did not become widely known. Most players understand the end of Black's counter-attack to be a combination of "Nobody Expects the Jerome Gambit!" and "Mars Attacks!"

10...Qxe4

This is a move that computers are fond of. See "Ionman vs the Bots" for some examples. 

11.Qxc7+ 

Instead, 11.Nc3 was seen in the game RevvedUp - Shredder 8, blitz 2 12, 2006 (0-1, 25) from the incredible match, RevvedUp vs Hiarcs 8, Shredder 8, Yace Paderborn, Crafty 19.19 and Fritz 8. See "Jerome Gambit: Drilling Down (1)" for starters.

11...Bd7 12.d3 Qd5 13.Nc3 Qc6 14.Qxc6 Bxc6 

LuigiBot has traded off its harassed Queen, but the situation looks kind of grim in any event. White is ahead the exchange and a couple of pawns; about a piece worth of material. Quite a change from less than a dozen moves ago!

15.Be3 Re8 16.Rae1 Re6 17.Bxc5 dxc5 18.Rxe6 Kxe6 

Radicalmove is content to continue to reduce the play to a basic endgame. 

19.a3 Kf5 20.h3 h6 21.b4 cxb4 22.axb4 Kf4 23.b5 

As if the current game were not bad enough, the two combatants played another game the same day (I do not know which was played first, but it might be the longer one) with the same result: 23.Re1 Bd7 24.h4 Bc6 25.g3+ Kf5 26.d4 Ne4 27.Nxe4 Bxe4 28.c4 b6 29.c5 h5 30.cxb6 axb6 31.Ra1 Bd5 32.Ra6 b5 33.Ra5 Ke4 34.Rxb5 Kxd4 35.Rb8 Kd3 36.b5 Kd4 37.b6 Kc5 38.b7 Kd4 39.Rd8 Ke4 40.b8Q Kd4 41.Qb7 Ke5 42.Qxd5+ Kf6 43.Rd7 Black resigned, radicalmove - LuigiBot, rated standard game, FICS, 2012.

23...Bd7 24.Re1 Bf5 25.h4 Bg4 26.g3+ Kf5 27.d4 Nd7 28.Na4 Bf3 29.Nc5 Nxc5 30.dxc5 Be4 

31.c4 Ke5 32.c6 a5 33.cxb7 Kd4 34.b8Q Bf5 35.Qb6+ Kxc4 36.Qxa5 Bd3 37.Qa4+ Black resigned

A Return to Pre-School

I think if the bodacious Blackmar Diemer Gambit (1.d4 d5 2.e4 dxd4 3.Nc3 Nf6 4.f3) can be referred to as a "high school for tactics" then the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) can at least be dubbed a "pre-school for tactics".

Every once-in-a-while I wonder if playing the Jerome is helping or hurting my chess play. Then I play a game like the following, and I stop worrying (for a while, anyhow).

I had the White pieces in a Four Knights game played online at FICS. If my opponent and I were stronger players, and if we were not playing blitz, it might be possible to talk of White having the slightest advantage due to his Bishop versus Black's Knight, or White's control of the e-file. As it was, we were both just trying to figure out what to do next.

22.Qe7 Rc8

It looks like Black wants to relieve his Queen from the task of guarding the pawn at c7. I found a way to keep him busy.

23.h4 Nf7 24.Re6 Nd6 

25.Bxf6

I could hear Bill Wall's voice in my head saying "Don't calculate, just play the sac!" It is clear that White can get three pawns for the piece, and, at worst, probably a draw by repetition. Of course, there could be even more. No reason to waste time deliberating.

25...gxf6

Already the critical error.

After the game Houdini suggested 25...Nf5!?, which led to 26.Rxc6 Nxe7 27.Re6 Ng6 28.Bc3 Nxh4 when White can tighten the pressure with 29.Re7, but his advantage would be better piece placement, not greater material. (This is how the "big boys" play.) White would have increased his edge, but there would be plenty of game left.

26.Qxf6 Rf8 

The game is already a mess, but this move, attacking White's Queen, is also a bit of a self-block, although the better 26...Re8 is not a whole lot better.

I had seen this far when playing 22.Qe7, a remarkable feat in and of itself for me. When I arrived at this position, I had enough time left that I could then see my way to a win – not the best or the fastest, but a win.  

27.Qg6+ Kh8 28.Qxh6+ Kg8 29.Rg6+ 

Sharper readers will see 29.Qg5+ Kh8 (29...Kf7 30.Qg6#) 30.Rh6 checkmate.

29...Kf7 30.Qg7+ Ke8 31.Re6+ Kd8 32.Qxf8+ Ne8 33.Rxc6 Black resigned

I was actually a bit relieved to see, after the game, that Houdini could find a "hole" in my plan – I wasn't quite ready to consider myself a "tactical maniac" yet, even if I do play the Jerome Gambit!

An Adventure

Researching and playing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) is a lot of fun, but I get the most enjoyment out of hearing from others who have discovered Alonzo Wheeler Jerome's impertinent opening, had had their own adventures.

Here's a recent email that I received; you will see what I mean.

Dear Rick,

I played your beloved Jerome Gambit in a real OTB tournament game (8 man 3 round Swiss G/30) at my local chess club last night.

First, a little background.  I played OTB rated chess at a chess club in the mid 1980’s as a young fanatic just out of school.  Then I got married and raised a family.  Chess was a rare occasional pleasure with friends or family.  I became known as sort of the Shane of my chess playing friends, trying to let the past remain in the past but getting called in from time to time to shoot down someone else’s evil black hatted nemesis.  But of course you know there is a world of difference between rated players and casual players.  So there is little real pleasure in beating Uncle Willie’s plumber.  Not even if it includes  a Fischer-esque ego crushing.

So after a 25 year absence I’ve started playing OTB USCF rated chess again.

I discovered your blog while googling “Bent Larsen quotes” and hit on this:

http://jeromegambit.blogspot.com/2011/08/powerful-like-storm.html

LOL.  Not the one I was searching for but fortuitously found out “why chess was invented”.  Truly a gift of the gods to a languishing chess world.  An adrenaline junkie’s wet dream.

In my sixth rated game since my return to chess, and the third game of last evening, I was playing white.  My opponent was rated in the mid-1300’s and my rating is probably comparable at this time.  We reached a Guioco Piano position after three moves.  My planned repertoire was to play the Evan’s Gambit vs GP and Max Lange Attack vs Two Knights Defense.   On a whim, I decided to play 4.Bxf7 and have some fun.

“This is totally unsound and should never be tried!” – GM Raymond Keene

With such an endorsement, who can resist?  Here’s the game.

White: Me

Black:  Mr. SF

G/30

1.e4            e5

2.Nf3          Nc6

3.Bc4          Bc5

4.Bxf7+      Kxf7

5.Nxe5+     Kf8

Unexpected.  Ke7 is the Paulsen variation.  I hadn’t seen this move on your blog….yet, but I’ve only read a few months worth of posts.  So from here, I’m on my own.  “Intelligence guided by experience.”  (OK Mr. Mystery writer - 10 extra credit points if you can identify that quote without google J)

6.Qh5         Nxe5

7.Qxe5       d6

8.Qh5         Qf6

9.d4            Bxd4

10.Be3       Bxe3

11.fxe3

I didn’t want to trade dark squared bishops, and I didn’t want to double the Jerome pawns, but I really, really wanted to open up the f-file for Rf1 pinning and winning the queen.  This is taking on the flavor of a Muzio King’s Gambit.

11. …           Qxb2

How to squirm out of this one?

12.O-O +   

The title of this should probably be “Thank You Mr. Polgar”.  I’ve been going through Chess: 5334 Problems, Combinations and Games lately and two themes popped up in my game.

Thank you Mr. Polgar.  The only “mate in one” that I had trouble with in your book was a mate that was delivered by white castling.  So it was fresh in my mind.  This doesn’t deliver mate obviously but it makes my game come alive and saves my rooks.

12. ….          Nf6

13.Nd2        Qc3

14.e5           Qxe3+

15.Kh1        Qxe5

Well done by black.  At this point I’m thinking my game is going nowhere.  I’m down material, my attack is fading, and I don’t have the Jerome big pawn center to shove down black’s throat.  But this is no ordinary game.  This is the Jerome Gambit!  All you have to do is jump on its back and hang on for the ride!  Right?  Right???

16.Qf3          d5

17.Rae1       Qg5

What to do… what to do…. Ah ha!  Let’s sneak in the back door and stir up the hen house.

18.Qa3+      Kf7

19.Qe7+      Kg6

20.Re3

With the intention of Rg3 pinning and winning the queen.  I have to be careful about the back rank mate threats.  I almost played Rf3??

20. …           Re8

21.Rxf6+     Qxf6

22.Qxe8+    Kh6

23.h3

Removing the back rank mate threat and setting up my next two moves.

 

23. …               Qf4

24.g4                b6

He missed the point of g4 entirely.
 

Thank you Mr. Polgar for including a lot of examples in your book of utilizing pawns to help deliver checkmate.  This was the second game of the evening that my pawn pushes put my opponent’s king in peril.

25.Qh5 #

Obviously not a high quality game.  I’m sure we both missed many opportunities.  Just two class C players doing their best.

Thanks for the blog.  Do I have the USCF apply my gained rating points to you?

Sincerely,

Mr. J.E.

Danville, IL

A fine adventure, eh, Readers? Many thanks for sharing, Joe.

(From Danville, IL, huh? That reminds me of Danville, Kentucky, which reminds me of the Danvers Opening and the Kentucky Opening, which the Jerome Gambit reminded J.H. Blackburne of... But I digress. - Rick)
