Again the Nightmare


In light of the earlier "The Pawns! The Pawns!", alternate titles for this post easily came to mind, such as "Nothing Succeeds Like Excess" or "Too Much is Not Enough" - but whatever you call it, today we see more bad dreams for Black, thanks to the "Jerome pawns."

Wall, Bill - Atacan

PlayChess.com, 2013

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 



7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 




9...Be6


Also seen is 9...N8e7, from perrypawnpusher - rsiemon, blitz, FICS, 2011 (1-0,23).


10.f4


Or 10.O-O, as in Wall,B - Parsom, Chess.com, 2010, (1-0, 25).


10...Bd7


The Bishop can  also go the other way, 10...Bf7, as in perrypawnpusher - Kingsmeal, blitz, FICS, 2010 (0-1, 25) and perrypawnpusher - GabrielChime, blitz, FICS, 2010 (1-0, 33).


A more spirited reply is 10...Qh4+, as in perrypawnpusher - udofink, blitz, FICS, 2010 (1-0, 29). 


11.O-O N8e7 12.d4


Or 12.f5 as in perrypawnpusher - nmuffjgp, blitz, FICS, 2010 (1-0, 23).


12...h5


Black looks like he wants to join in the pawn fun, but he soon is out-played.


13.c4 h4 14.b4 h3 15.g3 Bg4 16.f5 Nf8 17.d5



The "Jerome pawns" in all their (initial) glory.


A humorous alternative, pointed out by Bill, is 17.Rf4 Bh5 18.Rh4 winning Black's advanced pawn.


17...c6 18.a4 cxd5 19.exd5 Qc7 20.Rf4 Bd1



Humorous, but Black cannot really afford this levity.


21.Nc3 Bc2 22.f6 gxf6 23.Nb5 Qb6 24.c5 dxc5 25.bxc5 Qa5




Now comes the finish, and the "Jerome pawns" do their part.


26.Rxf6 Qd8 27.Nd6+ Kd7 28.Nxb7 Qe8 29.c6+ Kc7 30.d6+ Kxc6 31.Qc5+ Kxb7 32.Qc7+ Ka6 33.d7+ Black resigned

Update: Old Dog Can Still Bite


Most chess players, if they have ever heard of the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), know of the game Amateur - Blackburne, London, 1885, where the British master dismantled the opening and then destroyed it with a Queen sacrifice. They have a pretty good assessment of the Blackburne Defense, 4...Kxf7 5.Nxe5 Nxe5 6.Qh5+ g6 7.Qxe5 d6!?, giving up the Rook to distract, and, eventually trap out of play, White's Queen.

Players more familiar with the Jerome Gambit may have seen analysis that indicates that White, not Black, is better in this line.

Players very familiar with the Jerome Gambit may have seen analysis that indicates Black can draw, or force a draw, in a very, very complicated position.

All of which suggests that White can be happy when facing the Blackburne defense - if he knows what he is doing. Otherwise, that old dog is likely to bite, as in the following game.

burraburra  - rsiemon
blitz, FICS, 2012

1.e4 e5 2.Bc4 Nc6 3.Nf3 Bc5 4.Bxf7+ 




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




8.Qxh8 Qh4 9.g3

White's Queen-escape line is, instead, 9.0-0 Nf6 10.Qd8 Bb6 11.e5 dxe5 12.Qd3.

This seems a lot saner than 9.d4, e.g. 9...Nf6 (or 9...Qxe4+) 10.e5 dxe5 11.Nd2 Bxd4 12.0-0 Be6!? when there is plenty of madness in the position after 13.Nf3 (or 13.Qxa8 Bd5 14.Qc8 Ng4 15.Qxc7+ [15.Nf3 Bxf3 16.Qxc7+ Kg8 17.Qc4+ Kf8 18.Bh6+ Qxh6 19.Qc8+ Ke7 20.Qc7+ etc] 15...Ke8 16.Nf3 Bxf3 17.Bf4 Bxf2+ 18.Kh1 Qh3 19.Qc8+ Ke7 20.Bg5+ Kf7 21.Qxg4 Qxg4 22.Rxf2 Qxg5 23.Rxf3+ Kg7 24.Re1) 13...Bxf2+ 14.Rxf2 Qxf2+ 15.Kxf2 Rxh8 16.Nxe5+. The game is even, if White survives.

However, the text in the game, 9.g3 wins - for Black.

9...Qxe4+ 10.Kf1 Qxh1+


Or 10...Bh3+, Black resigned, facing 11.Kg1 Qg2# as in LukeWarm - blackburne, Jerome Gambit Thematic, 2010.


11.Ke2 Qe4+ 12.Kd1 Bg4+ 13.f3 Bxf3 checkmate

Rope-A-Dope


The following game has a sense of strangeness about it.

It was as if my opponent were adopting a rope-a-dope strategy against me. It worked, up until the point when it didn't...



 
perrypawnpusher  - rsiemon
blitz, FICS, 2011

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


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6


7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 N8e7


10.f4

This is about as strong as 10.0-0 (which will come next move) or 10.d4 (which never quite arrives).

10...Bd7

To fight against White's e-pawn. Better, although looking anti-positional, was 10...c5.

11.0-0

The next time I play this line, I will opt for more center action with 11.f5 Ne5 12.d4 N5c6 13.Nc3 Kf7 and then 14.0-0 with a roughly even game.

11...Bc6 12.f5 Nf8



Come and get me!

My next move tries to do just that, but there is not a whole lot for White in either (slightly better) alternative: 13.Nc3 Nd7 14.d4 Nf6 15.e5 dxe5 16.dxe5 Nfd5 or 13.d4 Nd7 14.c4 Nf6 15.e5 dxe5 16.dxe5 Ng4

13.f6 gxf6 14.Rxf6 Ng8


Come and get me!

15.Rf1 Qe7 16.d3 Rd8

After the game Rybka 3 suggested 16...Qg7 17.Bd2 Nd7 18.Nc3 Ne7 19.Rf2 Rg8 20.Qe2 b5 21.Raf1 Ne5 as about even.

17.Qg3

Again, Rybka 3's post-mortem suggestion was 17.Nc3 Qg7 18.d4 Nf6 19.Qg5 Qxg5 20.Bxg5 Nxe4 21.Rae1 d5 22.Bf6 Rg8 23.Nxe4 dxe4 24.c4 Kd7 25.Bxd8 Kxd8 26.d5 Be8 27.Rxe4 when White has a Rook and two pawns to Black's two pieces.

17...Rd7

Time to castle-by-hand on the Queenside... Funny! 

18.Nc3 Qg7 19.Qh3 Kd8 20.Be3 Kc8


By this time in the "Rumble in the Jungle", George Foreman had largely worn himself out against Muhammad Ali and his rope-a-dope tactics.

21.Rf2 Kb8 22.Raf1 Rd8


Black finally drops his guard.

23.Rf7

Here, Black forfeited on time. After the necessary 23...Qg6 he would lose a Knight to 24.Rxf8.
