More and More About What We Know So Little



In the last few days I have added over 10,000 Abrahams Jerome Gambit games (1.e4 e5 2.Bc4 Bc5 3.Bxf7+), which we have been discussing recently, to The Database, pushing it almost to 51,000 games, total. (I can probably add another 10,000 Abrahams JG games to bring things up-to-date with play at FICS.)

Reviewing my email files, I note that in the past I have discussed the opening with the always-impressive IM/PhD Tim Harding (whose 1973 Bishop's Opening is a classic, whose articles for chesscafe.com  helped answer the question "What Exactly Is the Bishop's Opening?", and whose biography of Joseph Henry Blackburne many await from McFarland) and with Michael Goeller, who maintains an excellent online resource on the Bishop's Opening; and neither was familiar with the early Bishop sacrifice.

That pretty much makes three of us.

I have recently contacted IM Gary Lane, a long-time friend of this blog, who has written Winning With the Bishop's Opening (1993) and The Bishop's Opening Explained (2005). While he is not familiar with the Abrahams Jerome Gambit, either, he is willing to take a look at it with his readers in his next month's "Opening Lanes" column at ChessCafe.com. 

I hope to learn more - much more. I need to. It is ridiculous that the "oldest" over-the-board game example of this line in The Database is a 2003 game:

Kuckuck,D - Loesche,N

The "oldest" online game example in The Database is only from 1999.

Exploring

Image result for free clip art exploring

After the previous post ("Keep Your Eye on the Prize") I started gathering thousands of Abrahams Jerome Gambit games and adding them to The Database, to develop a better understanding of the opening.

As the following game shows, theory of some of the variations is not far developed.


macele - torment

blitz, FICS, 2005

1.e4 e5 2.Bc4 Bc5 3.Bxf7+ 




3...Kxf7 4.Qh5+ Ke6 5.Nf3 




I was surprised to see that this move leads to an even game. So far, less than half of the games in The Database have this move.


Now, after 5...Nc6, the position would resemble a Jerome Gambit where the "ghost" White Queen has passed through the White Knight to deliver check.


5...d6 6.Ng5+ 


I have always been suspicious of this move in the Jerome Gambit proper, but here it seems necessary.


6...Kd7 7.Nf7 Qf6


One of a few equal responses. Black could have tried 7...Qf8 8.f3 Nf6 9.Qh3+ Kc6 10.g4 Qxf7 11.Qf1 d5 12.exd5+ Qxd5 13.Nc3 Qe6 14.Qb5+ Kd6 15.b4 b6 16.bxc5+ bxc5 17 Ba3 c6 18.Qxc5+ Kd7 19.O-O Nxg4 20.fxg4 Qxg4+ 21.Kh1 Bb7 22.Rg1 Qf3+ 23.Rg2 Re8 24.Kg1 Ba6 25.d3 Bb7 26.Rf1 Qh5 27.Rxg7+ Kc8 28.Qd6 Black resigned, Turkman - andrecoenen,  FICS, 2006.

Keep Your Eye On The Prize

Putting Black's Queen on f6, with the idea of exchanging Her Majesty, is a common anti-Jerome Gambit strategy. In the following game, Black introduces the plan, then wavers - and the game ends quickly.


Philidor 1792 - guest1862
3 0 blitz, www.bereg.ru, 2015

1.e4 e5 2.Bc4 Bc5 3.Bxf7+ 




Another example of the Abrahams Jerome Gambit.


As far as I can tell, Alonzo Wheeler Jerome did not play the Bishop sacrifice out of the Bishop's Opening, but Gerald Abrahams attributed the gambit to him nonetheless.


4...Kxf7 4.Qh5+ Ke6 5.Qf5+ 


Houdini judges the Abrahams Jerome less harshly than it does the Jerome proper, suggesting that here 5.Nf3, instead, equalizes. This bears further examination, as this blog has in the past presented only two losses by White with 5.Nf3 - see "The Abrahams Jerome Gambit (Part II)".


5...Kd6 6.Nf3 Qf6 7.d4 Bxd4 




Black overlooks the reason behind his 6th move, that of exchanging Queens, and is subsequently severely punished.

Shelter In Place


All of my games in the first round of the ongoing Chess.com Italian Game tournament (see  "Anybody Want A Couple of Pieces?") have been completed (without a Jerome Gambit in sight), and with 7 wins, 3 draws and 2 losses, I have to wait to see how many of my erstwhile opponents - I am thinking of LVercotti (currently 8 wins and 1 draw), mikerj (currently 6 wins, 1 draw and 2 losses) and FedorMarkov (currently 6 wins, 1 draw and 2 losses ) in particular - catch or pass me. I think three players advance to the next round, so I have my chances...

In the meantime, in the third round of the earlier Chess.com Italian Game tournament, (see "Anybody want a (couple of) piece(s) of me?") I managed a successful Jerome Gambit (see "Do I Share Everything? No.") but I do not think that I will be advancing to the next round, as that may be my only win. Que sera sera.

Theory on Non-Theory



Even in the non-main-line lines of the non-main-line Jerome Gambit, there is theory, and practice, as Philidor1792 demonstrates in the game below.

Philidor1792 - jenskun
Russia Central Federal District vs Phil, 
Chess.com, 2015

1.e4 e5 2. Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 



5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Ke7 



Infrequently played, but not bad.

8. Qxc5+

The experimental 8.Qg5+ was tried in Wall,B - CKFM, FICS, 2012 (1-0, 44). 

8... d6 9. Qe3 

The Database has three games with 9.Qg5+: fehim - Schiele, FICS, 2006, (0-1, 59); stampyshortlegs - calchess10, JGTourney4, ChessWorld 2009 (1-0, 31); and Wall,B - Vassilev,R, Chess.com, 2010 (1-0, 32).

9... Be6

Instead, 9... Nf6 was seen in three MrJoker games:  MrJoker - Yuvi, ICC, 2011 (1-0, 16); MrJoker - Cleanbishop, ICC, 2012 (1-0, 46); and MrJoker - taz, ICC, 2013 (1-0, 43).

The Bishop move seems to invite f2-f4 by White, gaining a tempo.

10.O-O Nf6 11.f4 Bf7 12.f5 Ne5 13.d4 Nc6 14.e5 dxe5 15.dxe5 Nd5 16.Qg3 Kf8 

The extra tempo for White, the "Jerome pawns" and Black's uneasy King have lead to an equal game. As we have frequently seen in Jerome Gambit lore, when White has equalized, he has the advantage.

17.Bg5 Qc8 18.e6 Bh5 19.Nc3 Nxc3 20.Qxc3 Rg8 21.f6 gxf6 22.Qxf6+ Ke8 23.Rad1 Qd8 24.Rxd8+ Rxd8 25.b4 b5 26.a4 a6 27.axb5 Black resigned

Do I Share Everything? No.

I have shared the good and the bad about the Jerome Gambit on this blog - winning games and losing games, helpful analysis and scary analysis.

But I haven't shared everything.


Here is an example from last year, drawn from the post "Jerome pawns -Clowning Around" where I was discussing preparations for my first-round game against djdave28 in the current Chess.com Italian Game tournament

After my discouraging loss with the Jerome Gambit in my previous Chess.comItalian Game tournament (perrypawnpusher - Buddy_Thompson), I knew that I had to cook up something new, or risk facing a future opponent who just "looked the refutation up" (and not even on this blog, mind you, but in my recent games on Chess.com).
I was happy that I did do the research, too, because in my third Jerome Gambit in my current tourney, my opponent went straight for the same line (leaving out the superfluous Queen check).
I won that encounter, and two rounds later I found myself facing the same opponent. Would he repeat the line - even though I had been victorious? Of course he would!

14...Kd5 15.Rf8 


This move is the result of research into my previous game with my opponent. You won't find it in my notes to that match, however.


What does it do? Not very much. It has some stifling effect on Black's development, but it conjures up something a Bizarro Nimzovich might have commented upon: It's strong because it is so weak! It does so much by doing so little!


It actually emboldens Black's King to stay around the center of action, and return a piece for a couple of pawns.


15...a5 16.b5 Kc4 17.Na3+ Kxc3 18.Rf3+ Kxd4 

19.Bb2+ Kd5+ 20.Kf1 Bd4 21.Rd1 Nf6



Black has two extra pawns, but his King looks pretty shaky.


Does White have an attack, or is he reduced to pawn-grabbing?


22.Bxd4 Ke6 23. Bxf6 gxf6 24.Re1+ Kf7 25.Rc3




This definitely looks like prospecting for pawns, and perhaps Black should let White have his way with 25...Kg6 26.Rxc7 d5. The theme of "Black's light-squared Bishop staying at home, undeveloped and blocking his Rook" would slowly be addressed by the defender.


25...c6 26.Nc4 


Headed toward the "hole" at d6.


26...d5 27.Nd6+ Kg6 28.Rg3+


Suddenly the idea of invading the 7th rank suggests itself to White, along with taking advantage of the unfortunate Bishop at c8 and the pawn it defends at b7..


28....Kh5 29.b6 


Another "do nothing" move. There was no way that I was going to exchange this pawn off and open lines for Black's Bishop. If my opponent's connected and passed c- and d-pawns were going to be the death of me - then, so be it.


29...Rb8 30.Re7 Bg4 31.h3 Bc8 32.Rgg7 




Black resigned


It might seem a bit early for the second player to give up the ghost, but his position certainly is tied up.

It's Complicated

Bill Wall scores over 95% with the Jerome Gambit, which is fantastic given that the opening has several "refutations." He keeps trying different ideas, and continues to be successful with them, although I don't always know how. 

It's complicated.


Here's an example, with sidelines - many games starring members of the Jerome Gambit Gemeinde.

8.Qxc2 Bxe3 9.fxe3 


Not 9.Qe2?, although White eventually got the point: 9...Bd4 10.Qf3+ Nf6 11.Qa3+ c5 12.Nc3 Bxe5 13.Qxc5+ d6 14.Qe3 Qa5 15.0-0 Be6 16.Rad1 Rd8 17.Qf3 Kf7 18.Nd5 Bxd5 19.exd5 Rhe8 20.g4 Kg8 21.g5 Nxd5 22.Rxd5 Rf8 23.Qe4 Qxa2 24.g6 h6 25.Rb5 b6 26.Qd5+ Kh8 27.Qxa2 Rf6 28.Rd1 Rxg6+ 29.Kf1 Bxh2 30.Ke2 Re8+ 31.Kd2 Rc8 32.Rf5 a5 33.Qb1 Rd8 34.Rf8+ Rxf8 35.Qxg6 Bf4+ 36.Kc2 Be5 37.Kb3 Rf3+ 38.Ka4 Rxf2 39.Qe8+ Kh7 40.Rb1 Bxb2 41.Qe4+ Kh8 42.Qa8+ Kh7 43.Re1 Be5 44.Rxe5 dxe5 45.Qe4+ Kg8 46.Qxe5 Ra2+ 47.Kb5 Rb2+ 48.Ka6 Rb3 49.Qe6+ Kh7 50.Qxb3 h5 51.Qh3 Kh6 52.Kxb6 g5 53.Qe6+ Kg7 54.Qe5+ Kh6 55.Qf6+ Kh7 56.Qxg5 a4 57.Qxh5+ Kg7 58.Qa5 a3 59.Qxa3 Kg6 60.Kc6 Kg5 61.Kd6 Kf5 62.Qc5+ Ke4 63.Qe5+ Kd3 64.Kd5 Kd2 65.Kd4 Kc2 66.Qe2+ Kb3 67.Qc4+ Ka3 Black resigned,  Athenee - dorigprg, FICS, 2006. 


9...Nf6


Bill mentioned Black could have tried 9...Qh4+ 10.g3 Qe7. 


10.0-0 d6 11.Nd3 g6


White's development, and Black's iffy King, are more important than White's doubled and isolated pawns. Now Black allows a small combination.


12.Nc3 Kg7 13.Nb5 c6 14.Nxd6 Qxd6 15.e5 Qd7 16.exf6+ Kh6




 Bill notes: 16...Kf7? 17.Ne5+; or 16...Kf8 17.Qc5+; or 16...Kg8 17.f7+ Kf8 18.Qc3


17.Ne5 Qd5 18.Qc3 Re8 19.f7 Rf8 20.Rf4 Qd8 




Or, per Bill, 20...Kh5 21.g4+ Bxg4 22.e4 Qd8 23.Rxg4 Kh6 24.Nf3 Rxf7 25.Rh4+.


21.Nf3 Be6 22.g4 g5 23.Rf6+ Kg7 24.Rxe6+



Black resigned
