Go On, Take The Money And Run



Black does well defending against the Jerome Gambit in the following game, until he becomes careless, and all of his gains disappear quickly.

Wall, Bill - Guest2905635
PlayChess.com, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 5.Bxf7+ Kxf7




The Italian Four Knights Jerome Gambit, a transition from 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nc3 Nf6.

6.d3 Re8

Or:

6...Ng4 7.Ng5+ Ke8 (7...Kg8 as in Wall,B - Richard123, Chess.com, 2010 [1-0, 10]) 8.Qxg4 h6 9.Qh5+ Ke7 10.Qf7+ Kd6 11.Nb5 checkmate, Wall,B - 321, InstantChess, 2015; or

6...Bb4 7.O-O Bxc3 8.Ng5+ Kg8 9.bxc3 h6 10.Nf3 d5 11.exd5 Qxd5 12.Be3 Bg4 13.c4 Qd8 14.h3 Be6 15.Rb1 b6 16.Re1 e4 17.dxe4 Bxc4 18.e5 Nd7 19.Qd2 Bxa2 20.Rbd1 Be6 21.Qc3
Ne7 22.Nd4 Bd5 23.Nf5 Nxf5 24.Rxd5 Ne7 25.Rd4 c5 26.Qc4+ Kh7 27.Qd3+Kg8 28.Rxd7 Qf8 29.Ra1 Nf5 30.Qd5+ Kh7 31.Rf7 Qg8 32.e6 Black resigned, Wall,B - Boris, SparkChess.com, 2012; or

6... Bxf2+ as in Wall,B - Igidius, PlayChess.com, 2015 (1-0, 15); or

6... Rf8 as in Wall,B - BarAbbas, PlayChess.com, 2012 (1-0, 45) 

7.O-O g6

Instead, 7...Nd4 was seen in Wall,B - Albulus, PlayChess.com, 2015 (1-0, 44).

8.Nd5 Nxd5 9.exd5 Ne7 10.Nxe5+ Kg8 11.Bg5 d6 12.Nf3 Qd7



Black has unpinned his Knight and plans to grab the advanced d-pawn. It looks like a simple idea.

13.d4 Bb6 14.Re1 Nxd5 15.c4 Ne7

There.

16.c5 dxc5 17.Qb3+ Kf8 18.Bh6 checkmate

Don't Try to Out-Think Me Redux



Image result for free clip art brainy

There is plenty of room in chess, at all levels, for a dash of "psychology", but it should only replace "good moves" in dire (or controlled) circumstances. Otherwise the outcome is likely to be something like the following.

(Here we have another example of the aphorism: in the Jerome Gambit, when White has equalized, he has the advantage.)

Wall,B - Igidius
PlayChess.com, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.d3 Bc5 5.Bxf7+ Kxf7 6.Nc3 




This time Bill chooses to develop his Knight over castling in this "modern" Jerome Gambit - for alternatives, see "Winning With the Jerome Gambit: A Game Full of Lessons".


6...Bxf2+


There was nothing wrong with 6...d6.


In other games opponents have tried 6...Ng4 (Wall,B - Richard123, Chess.com, 2010 [1-0, 10]); and 6...Rf8 (Wall,B - BarAbbas, PlayChess.com, 2012 [1-0, 45]).


With the text Black returns the "favor" of a sacrificed piece to create a displaced (and possibly vulnerable) King. Of course, he also moves from an "objectively" won game to an even game, which is generous of him. Such "psychology" appears regularly in Jerome Gambit games, and White can always say "thank you".


As I have cautioned the defender before: Don't try to out-think me, just play the refutation. 


7.Kxf2 Ng4+ 8.Kf1


Black's attack goes nowhere, but it is fun to include a game to show how it might have gone - with a good bit of luck and cooperation - 8.Kg3 d6 9.Ng5+ Kg6 10.h3 h6 11.hxg4 hxg5 12.Rxh8 Qxh8 13.Nd5 Qh4+ 14.Kf3 Bxg4+ 15.Ke3 Bxd1 16.Bd2 Qg3 checkmate, RomanDurdis - varsa, FICS, 2005. 


8...Rf8 9.Bg5 Qe8


Bill suggests, instead, 9...Nf6 10.Nd5 Nxd5 11.exd5 Ne7 with a roughly equal game. 


10.h3 h6 11.hxg4 hxg5 12.Qd2 Kg8 


Black gives up a pawn, perhaps thinking that it leaves White only a doubled, isolated pawn ahead; and, in the meantime, he safeguards his King. He puts his faith in his counter-attacking Knight.


13.Qxg5 Nd4


The piece hits the Knight at f3 and the pawn at c2. Surely this is compensation?!


14.Nd5 Nxf3 15.gxf3 Rxf3+ 




See, Black now has his pawn back.


Alas, White now has checkmate.


How did this happen??


16.Kg2 Qf7 17.Ne7+ Black resigned
