A Pawn Is Worth A Little Trouble


I received some more games from Bill Wall, new to me if not all of them "new".

The following is a good example of Black defending against the Jerome Gambit with nefarious ideas of his own. (For perspective on this kind of "duel" see "Post Script".) He almost makes them work...

Wall, Bill - Royercordova
Chess.com, 2010

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.Qc4 


In his games Bill has chosen many different squares to retreat his Queen to. See "Spicy!" for alternatives.

9...Qf6

This move is often part of Black's defense in the Jerome Gambit.

Bill has also faced 9...Qe7 10.O-O Be6 11.Qa4+ Bd7 12.Qb4 b6 13.Nc3 c5 14.Qb3 Be6 15.Qa3 Ne5 16.d4 Nc4 17.Qa4+ Kf7 18.d5 Black resigned, Wall,B - Guest4027845, Chess.com, 2015 

10.O-O N8e7 11.d4 Nc6 12. c3 Bd7 13.f4 Rf8 14.d5 Na5 



The game has proceeded along typical Jerome Gambit lines: White has a relatively safe King and two useful extra pawns; Black has an extra piece, but his King is stuck in the center. The position is slightly in Black's favor, but it is "messy". It is about to get a whole lot messier.

15.Qxc7

A calculated risk (Bill gives the alternative 15.Qd3). As Wilhelm Steinitz reportedly said, "A pawn is worth a little trouble". In this case, White gains a pawn and loosens Blacks position a bit, but he risks having his Queen trapped.

The proper order of moves will be important. 

15...b6 

The idea here is clear. Bill gives a more refined version as a suggestion, 15...Bb5 16.Rf3 b6.

16.Na3 Rf7 17.Nc4 

White's Knight races to help his trapped and soon-to-be-threatened Queen. 

17...Bb5

Black's best, as Bill pointed out, was 17...Nxc4 18.Qxc4 Kf8, allowing the Queen to escape but perhaps reamaining with an edge. 

18.Nxd6+ Black resigned



After 18...Kf8 19.Nxf7 Qxf7 20.Qxf7+ Kxf7 21.Re1 White will have a Rook against Black's two Knights, but he will have four extra "Jerome pawns" to make up the difference.

Had Black played Bill's suggested 15...Bb5 16.Rf3 b6, White would not have been able to use his Knight for rescue and attack. For example, after 17.Na3, Black can simply retreat the Bishop with 17...Ba6, (although he could also win White's Queen with 17...Rf7 18.Nxb5 Rxc7 19.Nxc7+ Kf8 20.Nxa8 Qd8 21.Be3 Qxa8 22.Bd4 - White may have adequate compensation, however) when White's best chance is to complicate with 18.e5 dxe5 19.fxe5 Qd8.

Spicy!


It is said that "variety is the spice of life." 

While a defender may know that Bill Wall is going to play the Jerome Gambit, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+, he certainly will not know what variation Bill is going to spring upon him.


Wall,B - Guest2360621

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.Qa3




This is the 6th different Queen move that Bill has played in this position. As he notes, " I try to make a new move every time when I can, to see what happens.  The Queen can probably go anywhere as long as it is not taken or trapped."


Previously,


9.Qe3 - Wall,B - Parsom, Chess.com, 2010 (1-0, 25); Wall,B - HeHe, Chess.com, 2010 (1-0, 19); Wall,B - Reza,A, Chess.com, 2011 (1-0, 43); Wall,B - G3LC, PlayChess.com, 2011 (1-0, 22); Wall,B - Guest3312852, PlayChess.com, 2012 (1-0, 26);


9.Qh5 - Wall,B - Guest1475978, Sofia, 2013 (1-0, 28);


9.Qb5+ - Wall,B - Zhu,Y, Chess.com, 2011 (1-0, 19); Wall,B - Guest327668, PlayChess.com, 2012 (1-0, 22);


9.Qc4  - Wall,B - Royercordova, Chess.com, 2010 (1-0,18);


9.Qc3  - Wall,B - NFTM, FICS, 2010 (1-0, 22); Wall,B - Jaar,J, Chess.com, 2010 (1-0, 19).


For the record, Houdini 3, given 10 minutes "thought" for "infinite analysis", prefers 9.Qe3 (-.92), followed by 9.Qc3 (-1.17) and 9.Qb5+ (-1.29).


9...Nf6


The current game is the only one in The Database with this line. Bill suggests as an alternative 9...Qh4.


10.0-0 Be6


Not 10...Nxe4? because of 11.Qa4+.


11.f4 Bf7 12.f5 Ne5 13.d4 Nc6 14.d5


Bill suggests as well the alternative 14.Qd3


14...Ne5 


15.Re1 Qd7 16.Bf4 Nc4 17.Qc3 b5 18.b3 Nb6 19.e5 dxe5 20.Bxe5 


Threatening 21.Bxf6+, winning the knight. Now Black could keep things in balance with 20...Nxd5, but the threatened discovered check is too uncomfortable.


20...Kd8 21.Bxf6+ Kc8 22.Bxg7


A little stronger might be Bill's suggestion 22.Re7


22...Rg8 23.f6 


Threatening Re7 


23...Nxd5 24.Qd4 Qd6 25.c4 bxc4 26.bxc4 Nb6 


A bit better was 26...Nb4, threatening ...Nc2, winning the Rook, although White is still better after 27.Qxd6 cxd6 28.Nc3. 


27.Qxd6 cxd6 28.Re7 


28...Bxc4 29.f7 Bxf7 30.Rxf7 Nd7




The advanced "Jerome pawn" has cost Black a piece.


31.a4 Kc7 32.a5 Kc6 33.Na3 Nc5 34.Nc2 Rab8 35.Nd4+ Kd5 



Black threatens 36...Rxg7 37.Rxg7 Kxd4 


36.Nf5 Ne4 37.Rxa7 


Threatening Ne7+, forking King and Rook, but Black had enough here and resigned.
