BSJG: Move-by-Move

The following game - another recent one from GameKnot.com - allows a closer look at an interesting, more-positional variation of an otherwise wild, attacking opening.

Team match, GameKnot.com, 2014

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4

The Blackburne Shilling Gambit.

There are a number of ways to safely meet the BSG, including 4.Nxd4, 4.0-0, 4.d3 and 4.c3. Black wants to see 4.Nxe5?!, so he can respond with the thematic 4...Qg5!?

4.Bxf7+ 

The Blackburne Shilling Jerome Gambit. As a Jerome Gambit fan, I like the move. Also, it has been good to me - I have scored 91% in 41 games. (The Database* contains 4,452 BSJG games;White scores 56%.)

4...Kxf7 5.Nxe5+ Ke8 6.c3

This move shows up 398 times in The Database, scoring 55% for White. The major alternative is 6.Qh5+, which appears in 1,376 games, and with which White scores 61%.

Houdini 3 shows a slight preference for the text move, which doesn't surprise me, as 100% of my games contain the alternative.

6...Ne6

This move appears in 157 games, while the alternate retreat, 6...Nc6, appears 92 times. The challenging 6...Qg5 appears in 95 games. All score the same, plus or minus a percentage point or two.

7.d4

Here Houdini shows a slight preference for 7.Qh5+, leading to an even game.

7...d6 8.Nd3 Nf6 

This is a balanced position. (It must be remembered that Black cannot castle, as he has moved his King.)

A couple of ideas for White now include 9.Nd2, seen in the game GmCooper - Mazetov, lightning, FICS, 2001 (1-0, 28); and 9.d5 Nc5 10.Nxc5 dxc5 11.O-O, which is the choice of chess engines Houdini, Rybka and Stockfish.

9.e5 dxe5 10.Nxe5 Bd6 11.Qe2

Stronger might be 11.f4

11...Qe7 

In this tense position, White inexplicably dropped a piece, and the game was over.

12.Bg5 Nxg5 White resigned

[*A word about statistics. In any database devoted to a particular opening, the success of the line will be inflated, as partisans and publishers tend to show off successes, not abject failures. I have corrected for this somewhat, in that about 90% of the games in The Database are drawn from play at FICS, over a 12-year period - all the wins, losses and draws in each particular opening. Statistics in The Database, thus, largely reflect the results of "average" club players in an "average" online game environment.] 

Timid

The defender who plays timidly against the Jerome Gambit is likely to face some annoying, advancing "Jerome pawns". This is especially the case in the 5.c3 "modern" variation of the opening, as  seen in the game below.

GmCooper  - ddp 
blitz, FICS, 2000

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.c3 h6

One can't be too careful, I guess.

6.d4 exd4 7.cxd4 Be7 

8.d5 Nb8

This is too much timidity, as White quickly shows.

9.Ne5+ Kf8 10.Ng6+ Kf7 11.Nxh8+ Kf8 12.Ng6+ Kf7 13.Qh5 

White is ahead the exchange and a pawn, and has the initiative.

13...Nf6 14.Ne5+ Kg8 15.Qf7+ Kh7 16.Qg6+ Kg8 17.Bxh6 d6 

Black could have mobilized a defense of his King with 17...Qf8 18.Nc3 d6 19.Nd3 Bd7 20.0-0 Be8 21.Qg3 Nbd7 22.Be3 when he would simply be behind in material.

Instead, he ends the pain.

18.Qxg7 checkmate

A Level of Strangeness

The following game has a surprise move in a less-than-usual line, and when I researched it in earlier posts, I found a number of editorial errors. Strange...

bemillsy - leoarthur
blitz, FICS, 2012

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.O-O Bc5 

See "Jerome Gambit vs Two Knights Defense (Part 4)".

5.Bxf7+

A delayed Jerome Gambit move order (or a transition to a "modern" Jerome Gambit line, 1.e4 e5 2.Nf3 Nc6 3.Bc3 Bc5 4.Bxf7+ Kxf7 5.0-0 Nf6), although there are about 550 examples in The Database. I have never played the line, but of course Bill Wall has, as have GeniusPawn, GmCooper, HauntedKnight, hinders, sTpny, Teterow, DragonTail and jrhumphrey, to name just a few.

The line was looked at in the games aymmd - MOMLASAM, blitz, FICS, 2010 (0-1, 19)  and Wall, B - Guest848078, PlayChess.com, 2012 (1-0, 10) although there were diagram errors and references that subsequently needed correction in both posts.

5...Kxf7 6.Nxe5+ Nxe5 7.d4 Nf3+ 

A surprise, but not as strong as the routine 7...Bxd4.

8.Qxf3

The correct capture, with a roughly equal game.

8...Bxd4 9.Bg5 

Overlooking something, perhaps already short of time.

9...Bxb2

Surprisingly, not Black's strongest move, although it does lead to some advantage. Rybka prefers 9...d6 10.Nd2 h6 11.Be3 Bxe3 12.Qxe3 Re8 13.f3 Qe7 14.Rad1 Be6 15.b3 Kg8 with a clear advantage.

10.Nd2 

White should try 10.Qb3+, as after 10...Kg6 11.Qxb2 Kxg5 12.e5 he has chances against Black's uneasy King.  

10...Bxa1 11.Rxa1 d6 White forfeited on time.

Fantastic!

In the last few days I have picked up hundreds of Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) and Jerome-ish or Jerome-ized games (e.g. 1.e4 e5 2.Nf3 Nc6 3.Nd4 Bxf7+) – perhaps as many as a thousand – from games played at the Free Internet Chess Server (FICS).

I am still organizing and reviewing the games, but it is quite possible that they will have an impact on current Jerome Gambit theory, and may even cause me to review and revise some of the information that I posted in the first year of this blog.

How exciting!

I will share what I learn, as I am able.

In the meantime, welcome to the Jerome Gambit Gemeinde, DragonTail, majorminor, JKELSEY, GmCooper, weenar, ItsAllBullCheck and KnightBiker (among others), all playing at FICS.
