Take My Pieces, But Take My Word, Too

Image result for free clipart proud

Sometimes the recipient of a gambit is skeptical. Free material? Why not grab all I can get?? The gamiteer adds: It will cost you.

In the following game Black happily receives a Bishop and then a pawn. When offered a Knight, he scarcely resists the temptation.

White then shows that his "generosity" should have been taken seriously, as well.

Philidor 1792 - NN

1.e4 e5 2.Bc4 Nf6 3.Bxf7+ Kxf7 4.Nf3 Nxe4 5.Nc3

Combining Jerome Gambit ideas with the Boden-Kieseritzky Gambit!

I have only seen this once, mentioning the idea in a note in an earlier post about an earlier Philidor 1792 game, referencing Jirotka,S - Super Expert, 1990; but The Database is incomplete concerning 1.e4 e5 2.Bc4 Nf6 3.Bxf7+.

We have seen 5.Nxe5+ in a number of White's games: Philidor 1792  -guest2044,, 2013 (1-0, 45); Philidor 1792 - guest213,, 2013 (1-0, 41); Philidor 1792 - guest564,, 2013 (1-0, 56); and Philidor 1792 - guest45,, 2013 (1-0, 28). 

5...Nxc3 6.dxc3 d6 

A typical mistake against the B-K.

7.Nxe5+ Ke6 8.0-0 Kxe5 

I was not being frivolous, thinks White, believe me.

Been There, Done That, Have the Points to Show It

Image result for free clipart chess

As I play through new (to me) Bill Wall games, I am surprised at how many people throw the Blackburne Shilling Gambit back at his Jerome Gambit. Maybe they really expect him to play 4.Nxe5?!. Maybe they don't know about the Blackburne Shilling Jerome Gambit. The fact is, when it comes to the BSJG, Bill's been there - and has the points to prove it.

Wall, Bill - Amoex, 2013

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+ 

The Blackburne Shilling Jerome Gambit.

4...Kxf7 5. Nxe5+ Ke8

There are other choices, as Bill has encountered:

5...Kf6 6. f4 (for variety: 6.Ng4+ as in Wall,B - GYHZ, FICS, 2010 [1-0, 36] and Wall,B-Darksquare,,  15 0, 2010 [1-0, 23]) 6...g6 7.c3 Ne6 8.O-O Ne7 9.Ng4+ Kg7 10.f5 Nc5 11.f6+ Kg8 12.d4 Ne6 13.f7+ Kg7 14.Bh6 checkmate, Wall,B - Mora, E,, 2010; or

5...Ke6 as in Wall,B - apollyon, 2010,, 2010 (1-0, 12)

A bit stronger is 6.c3 which Bill has also played 6...Ne6 (6...Nc6 7.Nxc6 dxc6 8.Qh5+ Ke7 (8...g6 9.Qe5+ Qe7 10.Qxh8 Qxe4+ 11.Kd1 Qxg2 12.Re1+ Ne7 13.d3 Qxf2 14.h3 Bf5 15.Bg5 Qf3+ 16.Kc1 Kd7 17.Qxh7 Re8 18.d4 Qg3 19.Bd2 Bxh3 20.Na3 Bf5 21.Nc4 Kd8 22.Ne5 a6 23.Qh1 Kc8 24.Rg1 Qf2 25.Rg2 Qxg2 26.Qxg2 Nd5 27.Nxg6 Bxg6 28.Qxg6 Re7 29.Qf5+, Black resigned, Wall,B - Apple,, 2010) 9.d4 Nf6 10.Qf3 Kf7 11.e5 Bg4 12.Qf4 Qe8 13.Be3 Bd6 14.exd6 cxd6 15.Qxd6 Ne4 16.Qc7+ Kf8 17.Qxb7 Rb8 18.Qxa7 Rxb2 19.Qa3+ Black resigned, Wall,B-Verrsili,, 20107.Qh5+ g6 8.Nxg6 hxg6 9.Qxh8 Nh6 (9...Nf6 10.d3 Qe7 11.Be3 d6 12.O-O b6 13.Bh6 Kd7 14.Bxf8 Nxf8 15.Nd2 Ba6 16.Qh3+ Ne6 17.Nb3 Qh7 18.Qxh7+ Nxh7 19.c4 Rh8 20.f4 Rg8 21.f5 gxf5 22.exf5 Black resigned, Wall,B - Toyong,, 201010.O-O Nf4 11.Qe5+ Ne6 12.Qg3 Qg5 13.Qxg5 Nxg5 14.d4 Nhf7 15.Nd2 Be7 16.f4 Ne6 17.f5 gxf5 18.exf5 Neg5 19.g4 Bf6 20.h4 Nh7 21.Nf3 Nd6 22.Bf4 Ne4 23.Bxc7 d5 24.c4 Bd7 25.cxd5 Kf7 26.Ne5+ Bxe5 27.dxe5 Bb5 28.Rfe1 Nd2 29.e6+ Ke7 30.d6+ Ke8 31.d7+ Bxd7 32.exd7+ Kxd7 33.Rad1 Kxc7 34.Rxd2 Black resigned, Wall,B - Klevic,, 2014.

White has two choices here, and two pieces of advice. The Database has 98 games with 8.Qxg6, with White scoring 58%; and
369 games with 8.Qxh8, with White scoring 52%. On the other hand, Stockfish recommends 8.Qxh8  and after 8...Nxc2+ 9.Kd1 Nxa1 10.Qxg8 Qg5 gives Black the edge.

As is often the case in club chess, the player who knows better what is going on in the game has the advantage - as the following moves show.

8...Ke7 9.Qg5+ Ke8 10.Qe5+ Ne6 11.Qxh8

White gathers in the Rook, after all. He has a Rook and four pawns against Black's extra two pieces.

Still, Black races to take advantage of White's "sidetracked" Queen and attack the enemy King, only to wind up dropping a piece in the process.

I Don't Know How He Does It

Sometimes I play over the games of the top Jerome Gambit players and shake my head in wonder, admitting I don't know how he does it... So many times Black seems to be better - until he loses. Clearly, the Jerome is not only a study in the psychology of error, it is a school for learning about (successful) chess struggle. 

1.e4 e5 2.Bc4 Bc5 3.Bxf7+

It is interesting to note a couple of FICS games with a player with a similar name to White's, which give alternative responses:

Here we have a typical Jerome Gambit endgame, with the "Jerome pawns" vs Black's extra piece. "Objectively" the edge is to the second player, although it is his responsibility to show it. 

17.Rd3 Ng5 18.f3 Rhd8 19.h4 Ne6 20.Rhd1 Ne8 21.Bg3 Rxd3 22.Rxd3 Rd8 23.Kd2 Nf6 24.b3 Nh5 25.Bh2 Ke7 26.Ke3 h6 27.Rxd8 Kxd8 28.Be5 Ke7 29.f4 b5 

30.f5 Nc5 31.Bd4 Kd6 32.b4 Na6 33.a3 Nb8 34.Bxa7 Nc6 35.Bc5+ Ke5

Black's King successfully blockades the central "Jerome pawns", his b-pawn restrains White's Queenside, and even though he has given up a pawn, he seems to have stymied the first player's momentum. Except for one move.


White's game now becomes dyamic on the Queenside.

36...bxc4 37.b5 Nb8 38.b6 Nf6

This slip allows White to clarify things quickly with the win of a piece.
