What Happened??

Image result for free clipart What?

Black plays reasonable chess in the following game, as does White - who slowly moves the game toward equality. Then, suddenly, the second player deliberately hangs a piece, and White's attack on the enemy King crashes through. Can Readers uncover an explanation (other than "chess blindness") for Black's 17th move?

Wall, Bill - Guest7132040, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.d4 Bxd4 7.Qxd4 d6 8.O-O

Or 8.Qd5+ followed by 9.O-O as in Wall,B - Guest344942,, 2013 (1-0, 20).


8...Nf6 was seen in a number of previous games, for example:  Jerome,A - Shinkman,W, Iowa, 1876, (1/2 - 1/2, 42);  perrypawnpusher - JoseSoza,, 2012 (0-1, 34);  Wall,B - Guest903719,, 2013 (1-0, 47); and Wall,B - Guest1561957,, 2014 (1-0, 25).

9.f4 Nc6 10.Qc3 Nf6 11.f5 Bd7 12.Qb3+ Kf8 13.Re1 Nd4 14.Qd3 c5

15.Bf4 Bb5 16.Qd1 Qb6 17.c3 Ba4

White can just take the Bishop. What am I missing? (If Black is planning 18...Qxb2 it would be well met by the obvious 19.Nd2.)

Always Dangerous

The Blackburne Defense to the Jerome Gambit leads to a tense and complicated game for both sides. As Joseph Henry Blackburne demonstrated early in the life of the Jerome, Black can generate a wild counter-attack by returning one sacrificed piece and offering a Rook as well. On the other hand, analysis since has shown that White can draw, and practical play shows he can often do better - in games in The Database White scores 68%.

Philidor 1792 - NN

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 7.Qxe5 d6 8.Qd5+ 

White decides to steer clear of the dangers of 8.Qxh8 and grab another pawn. He hopes to show his three extra pawns will outweigh his opponent's extra piece. Philidor1792 has had significant success with the pawns vs the piece in the Jerome Gambit.


Seen previously was 8...Kg7 in RevvedUp - Fritz 8, 2 12, 2006 (0-1, 19).


Or 9.Qd3 Nf6 10.O-O Qe7 11.b3 Ng4 12.Bb2 Ne5 13.Qf3+ Nxf3+ 14.gxf3 Bh3 15.Bxh8 Qg5+ 16.Kh1 Qg2 checkmate, hattta - VictoriaBot, FICS, 2012. 


An anternate idea was 9...Rc8 seen in stampyshortlegs - Sir Osis of the Liver, JG Tourney4, ChessWorld, 2009 (1-0, 39). 

10.Qa6 Qh4 

At first glance it looks like Black is the one playing a gambit, with the subsequent lead in development of pieces. However, if White can consolidate his position behind his pawns, he can eventually put them on the march and look for balance.

As the game goes, Black uses his pieces to keep pressuring his opponent, and the point is his.

11.Qe2 Bg4 12.Qf1 Nf6 13.d3 d5 14.Nc3 Rhe8 15.h3 Bd7 16.g3 Qh5 17.f3 Bd4 18.Nd1 Kg7 19.Be3 Bxe3 20.Nxe3 dxe4 21.fxe4 Qa5+ 22. Kd1 Qc5 

So far White's pawn cover has held up, but his oppponent's pressure is relentless and his lead in development is crushing.

23.Qf2 Nxe4 24.dxe4 Rxe4 25.Re1 Rxb2 26.Re2 Bxh3 27.Ng2 Qd6+ 28.Kc1 Rbb4 29.Nf4 Bg4 30.Rxe4 Qd1 checkmate.

A Tale of Two Knights

Image result for free clipart knights

The following game has a Knight sortie for Black, and one for White. One is effective, one is not. The "Jerome pawns" join in the fun for White.

Wall, Bill -Guest293396, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.O-O Bc5 5.Bxf7+ 

We have seen this position recently in another of Bill Wall's games, vs Mydrik.

5....Kxf7 6.Nxe5+ Nxe5 7.d4 Bd6 8.dxe5 Bxe5 9.f4 Bd4+ 

Possibly a slip on Black's part, although the move has been seen before, so perhaps he was looking for a simple way to return the sacrificed piece. Still, 9...Bd6 10.e5 Bc5+ looked like a better choice, leading to an even game. 

10.Qxd4 Re8


10...d6 11.e5 dxe5 12.Qxd8 Rxd8 13.fxe5 Bg4 14.exf6 gxf6 15.Nc3 Rd7 16.Ne4 f5 17.Bg5 Kg6 18.Nc5 Rd5 19.Ne6 Re8 20.Nxc7 Black resigned, Fietsenzo - oritelgavi, FICS, 2014;

11.e5 Ng4

This "attack" is brushed off, but the retreat 11...Ng8 also has its difficulties, e.g. 12.Qd5+ Kf8 13.Nc3 d6 14.Qe4 Qh4 15.g3 Qh5 16.Qb4 c5 17.Qe4 h6 18.Nb5 Qf7 19.Nxd6 Qe6 20.Nxe8 Kxe8 21.f5 Qe7 22.Be3 Rb8 23.Rae1 b6 24.Bf4 Bb7 25.Qa4+ Kf8 26.f6 Qe6 27.fxg7+ Kxg7 28.Qxa7 Qd5 29.Qxb7+ Rxb7 30.e6 Qxa2 31.Be5+ Kg6White forfeited on time, frizerkaHR - cebop, FICS, 2013

12.h3 Nh6 13.f5 

The "Jerome pawns" are in their glory.

13...Ng8 14.Nc3 c6 15.Ne4 Qb6 16.Ng5+ 

This Knight will win material, and usher in the pawns.

16...Kf8 17.Nxh7+ Ke7 18.f6+ gxf6 19.exf6+ Nxf6 20.Qxb6 axb6 21.Nxf6 Black resigned

White is up a piece and a pawn, as well as having the safer King.
