A Nigerian Abrahams Jerome Gambit


The other day I came across a chess thread on a Nigerian website, 
Nairaland.com, with a post by InesQor, who wrote 
I just finished a chess game on this new site I found (lichess) and the game was really odd to me.
I won, but I'm wondering if the Jerome gambit my opponent played could ever have been played better than it was. Or else, if it is so terrible an opening?! Better players in the house, what do you think?...
Caveat: I haven't played chess in a while so I'm not in the best of form: playing fast (thus, there are some blunders.)
I am not sure that I am a better player than you are, but I am glad to be of some assistance, InesQor!

1.e4 e5 2.Bc4 Bc5 3.Bxf7+ Kxf7




The site lichess identifies this as "Bishop's Opening, Jerome Gambit". My preference is to refer to it as the "Abrahams Jerome Gambit" as opposed to the Jerome Gambit proper (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+).


The point is largely moot here, as with White's and Black's next moves, the game transposes to the "regular" Jerome Gambit.


4.Nf3


White would have better chances of an attack after 4.Qh5+, although Black still would be better.


The fact is that the Jerome Gambit is pretty much a terrible opening, although in a 3-minute blitz game between club players, it has some practical value.


4...Nc6 5.d3 


This move marks the game as a "modern" Jerome Gambit variation, as opposed to the "classical" lines which feature 5.Nxe5+ - a move that was almost always played back in the time of Alonzo Wheeler Jerome. However, modern players are not always willing to sacrifice a second piece.

5...Nf6 6.Bg5 Rf8 7.c3 Kg8 




Black has played very well, developing his pieces and castling-by-hand. It is up to White to show that he has any kind of compensation for his sacrificed piece.


8.Qb3+ Kh8 9.h4 Qe8 10.h5 Qe6 




Black offers to exchange Queens, snuffing out White's attacking chances. He could have gone further with the counter-attack 10...Ng4!?, sowing confusion in his opponent's ranks.


11.c4 Nxh5


A very sharp idea, if followed up correctly.


12.Rxh5 Bxf2+


Black misses 12...Qg4! with a chance to recover his sacrificed material (with interest), moving toward a strong attack on White's King. If he does not take advantage of his Queen's opportunities, White will recover - and the first player still has an extra piece.


13.Kxf2 Nd4 14.Qd1 d5




Things are looking complicated - and in a 3-minute game!


White has a chance to work on a counter-counter-attack, with 15.Be3, e.g. 15...dxe4 16.dxe4 Qg4 17.Qh1.


The game now bounces back and forth - time must have been running short for both players.


15.cxd5 Qb6 


A scary move - a strong tool in blitz - but the Queen would be better placed on g6. White's response is all bluff, however.


16.Rxh7+ Kxh7 17.Qh1+ Kg8 18.Kg3 Ne2+ 19.Kh4




Allowing checkmate, but White was worse in any event.


19...Qf2+ 20. Kh5 Ng3+ 21. Kg6 Nxh1 22. Nxe5 Rf6+ 23. Bxf6 Qxf6+ 24.Kh5 Qh6 checkmate



Very nice!

Doing the Enemy's Work


I like the Jerome Gambit in all its variations, and I love to show a snappy Jerome Gambit win; but sometimes it is necessary to balance the scale, and give Black a hand, too...

acuriel - DOCTOERDETROIT 
blitz, FICS, 2009

1.e4 e5 2.Bc4 Bc5 3.Bxf7+ Kxf7 4.Qh5+ Kf8 5.Qf5+ Nf6 6.Qxe5


Here is a position in the Abrahams Jerome Gambit that has been reached in 72 games in The Database. What is Black's best move now?

6...Bxf2+ 

Of course.

However, the move was played in only 7 of the aforementioned games, less than 10% of the time! Defenders, step up your game!

7.Kxf2 

Unwittingly going along with Black's plan.

7...Ng4+ 

Forking King and Queen.



White resigned

Borrowed As Good As Own


If you stay up-to-date with ideas in the Jerome Gambit (by reading this blog, for starters) there will always be some new ideas to pick up and use in your game.

Wall,B - Guest539122
PlayChess.com, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 


4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bd6 


Sharing HauntedKnight - galpone, blitz, FICS, 2014 (1-0, 18) in "Familiar Territory" earlier this year I wrote
When I was playing over this game, I saw Black's move and chuckled. HauntedKnight practially owns this line.
That doesn't mean, of course, that Bill Wall can't "borrow" it.

7.dxe5 Bxe5 8.Qd5+ 

In "Shortcut" I expressed a preference for this move over the also-strong 8,Qh5+.

8...Kf8 9.Qxe5 Qe7 


Black's Queen comes to the rescue, but White has already recovered his sacrificed piece and is a pawn up, with a safer King.

10.Qf4+ Nf6 11.Nc3 d6 12.0-0 Qe5 13.Qxe5 dxe5


Exchanging Queens often means the end of danger to the King - but not today.

14.f4 exf4 15.Bxf4 Ne8 16.Bd6+ Kg8 17.Rf8 checkmate



Please note the White Bishop at d6!

Reddit


While wandering the internet the other day, I ran into some interesting comments on the Busch-Gass Gambit ( See "Worth A Second Look" Part 1Part 2, and Part 3; as well as "Busch-Gass Gambit") at Reddit: 
www.reddit.com/r/chess/comments/2gcbgj/buschgass_gambit/


(Unrelated, but also interesting, was "Delightful Duel 'Banter Blitz' with Miss Tactics (IM Sopiko Guramishvili) and Miss Strategy (IM Anna Rudolf)".

Toward Disaster



As I have mentioned in an earlier post, I have joined a Chess.com 12-player "Giuoco Piano" tournament (3 groups of 4 players each).
I immediately got to start a couple of Jerome Gambits, so we'll see how they turn out.The first game is racing along the lines of a refutation that has many blog posts here, all saying that White is lost, White is lost...
Well, sad to say, White did lose - but part of the reason was my refusal to play a thematic "Jerome pawn" advance which would have helped keep the play dynamic. The second big mistake was to not be as familiar with Jerome Gambit history as I should be. Ouch.

perrypawnpusher - auswebby

Giuoco Piano Tournament, Chess.com, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 7.Qxe5 Qe7 8.Qf4+ Ke8



Instead, 8...Nf6 was seen in a couple of correspondence games between Daniel Jaeger (White) and Alonzo Wheeler Jerome  in 1880.


More reently, Bill Wall faced 8...Qf6 in a handful of games: Wall,B - GoldCoinCollector, Chess.com, 2010 (1-0, 17);  Wall,B - GuestZCLK, FICS, 2011 (1-0, 15); Wall,B - Guest340293, PlayChess.com 2012 (1-0, 41); Wall,B - Josti, PlayChess.com, 2013 (1-0, 26); and Wall,B - Guest4644930, PlayChess.com, 2014, (1-0, 26).


9.Nc3 Nf6 10.0-0 d6 


Or 10...Bd6 as in perrypawnpusher - Chesssafety, Chess.com 2012, (1-0, 25).


11.d3


White got away with the Knight jump 11.Nd5 in xcvbnm -SAHFAN, FICS, 2013 (1-0, 28), but I should have been more familiar with the game (in The Database) as Black was better most of the game; and White's win came only when his opponent blundered into a mate-in-2.


11...Be6 12.Be3 Bxe3 13.Qxe3 Kd7 14.f4 Rhf8 15.f5 Bg8 16.d4 Rae8 17.Rae1 Kc8 18.Qg3 




Instead, it was time for 18.e5. The text allows Black to take a step toward preventing that move, and my response (see the note to White's 11th move) sealed my doom.


18...Nd7 19.Nd5 Bxd5 20.exd5 Qf6 




I thought I had a few tricks against Black's King on the back rank, but, really, there was nothing.


21.Rxe8+ Rxe8 22.c3 Nb6 23.Re1 Qf7 24.f6 Rxe1+ 25.Qxe1 Qxf6 26.Qe8+ Qd8 27.Qf7 Qh8 28.b3 Nd7 29.c4 Kd8 30.Kf2 Qf8 31.Qxf8+ Nxf8 32.Kf3 Ke7 33.Ke4 Kf6 34.c5 Ng6 35.g3 b6 36.b4 Ne7 37.a3 b5 White resigned.

Even A Mess Can Be Educational


Immediately after blundering on move 11, I thought about resigning; but I decided to hold on for a move... then another... then another. Eventually, I held on for the win.

Blitz games can be very strange, and those featuring the Jerome Gambit even more so. Some of the positions in the following game might make up for the questionable play of both me and my opponent.

perrypawnpusher -Toscolano
blitz, FICS, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Ke8 8.Qxc5 Qh4



Surprisingly a TN according to The Database.

Of note, however, is that after 8...d6 9.Qe3 a successful computer choice was 9...Qh4 in RevvedUp - Yace Paderborn, 2 12 blitz, 2006. In the same competition, 7...Kf8 8.Qxc5+ d6 9.Qe3 Qh4 was seen in RevvedUp - Shredder 8, 2 12 blitz, 2006 and Shredder 8 - RevvedUp, 2 12 blitz, 2006.

9.Nc3 d6

An indication of how weird things were going to get is that after the game Houdini recommended, instead, 9...Qg4 10.Rg1 Kd8

10.Qe3

I probably could have taken the pawn with 10.Qxc7, but it looked complicated. After the game, Houdini agreed with me: 10...Qg4 11.Nb5 Qxe4+ 12.Kf1 Qe7 13.b3 Bf5 14.Ba3 Qxc7 15.Nxc7+ Kd7 16.Nxa8 Nf6 17.Nc7 Kxc7 18.d3  and things would be about balanced between White's extra Rook plus 2 pawns vs Black's two extra Knights.

10...Nf4 11.g3

A mindless move, after which I immediately thought of resigning. Of course, White needed to be brave and castle.

11...Ng2+ 12.Ke2 Bg4+

Strong, but even stronger would be 12...Qh5+

13.f3 Qh3 

Black is still better after playing the text, but it was time for 13...Nxe3 14.gxh4 Nxc2 15.Rb1 Bh5,  when Black would be up a piece for a pawn.

14.Qf2 Bh5

Black appears repelled by the tactical mess too, and continues to play "safe" and "normal" moves instead of doing concrete analysis - understandable in blitz.

After the game Houdini suggested that Black wade in and keep his advantage with 14...Ne7 15.d3 Rf8 16.Bf4 Nxf4+ 17.gxf4 Rxf4 18.Qg3 Rxf3 19.Qxh3 Rxh3+ 20.Kf2 Kd7. 



analysis diagram




15.d3

This is now good enough for equality, while 15.Rg1 would lead to a White advantage.

15...Nf6

This hands over the advantage - not that I was ready to take it! Black could maintain equality with 15...Ne7 16.g4 Bxg4 17.fxg4 Qxg4+ 18.Qf3 Qxf3+ 19.Kxf3 Nh4+.

16.Bg5

I was still floundering. Instead of this reasonable move White should have played 16. Rg1 with an small edge (2 pieces vs Rook) after 16...Rf8 17. Qxg2 Qxg2+ 18. Rxg2 Nxe4 19. dxe4 Bxf3+ 20. Kf1 Bxg2+ 21. Kxg2 Kd7.



analysis diagram






16...h6

Finally letting White off the hook. Instead, Black should have piled on with 16... Ng4, which wins, for example 17.fxg4 Qxg4+ 18.Kf1 (18.Kd2 Qxg5+ 19.Qf4 Nxf4; 18.Qf3 Qxf3+) 18...Rf8 19.Qxf8+ Kxf8 20.Kxg2 Qxg5

17.Bxf6 gxf6 18.Rag1 f5 19.Qxg2 Qxg2+ 20.Rxg2 fxe4 21.dxe4 Rf8 22.Rf2 c6 

The smoke has cleared, and White ("It is better to be lucky than good") is up a couple of pawns.

23.Rd1 Kd7 24.Rd3 Rae8 25.Kd2 

An ending slip.

25...d5 26.exd5 cxd5 27.Rxd5+ Kc6 28.Rxh5 Rd8+ 29.Kc1 Rfe8 30. Rxh6+ Kc7 31.Re2 Rf8 32.Re7+ Kc8 33.Rhh7 Rxf3 34.Rc7+ Kb8 35.Rxb7+ Kc8 36.Rhc7 checkmate



Okay, say it with me, "Nobody ever won a game by resigning." Lesson learned.
