Still Further Off The Beaten Path; And Not So Familiar


Image result for free clip art mail
Here's another Jerome Gambit game from shugart, playing at the Free Internet Chess Server (FICS). Unlike the play in the last post (see"A Familiar Line Off The Beaten Path"), this features a novel line that is truly new to White, and quite rare in The Database (it is one of three games).

shugart - bobbybo
FICS, 2016

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 



7.Qd5+ Kf8 8.Qxc5+ d6 9.Qh5 



9...Nf6

Black's move is an improvement over the less-challenging 9...N8e7, e.g. 10.O-O Be6 11.f4 Ke8 12.f5 Bf7 13.fxg6 Bxg6 14.Qf3 Qd7 15.Nc3 Kd8 16.d3 Qe6 17.Bg5 Kd7 18.Qe2 Rad8 19.d4 c6 20.d5 cxd5 21.exd5 Qxe2 22.Nxe2 Bxc2 23.Nd4 Bg6 24.Bxe7 Kxe7 25.Rae1+ Kd7 26.Nf5 Bxf5 27.Rxf5 g6 28.Rf7+ Kc8 29.Ree7 a6 30.Rxb7 Rde8 31.Rxh7 Rxh7 32.Rxh7 Re1+ 33.Kf2 Rd1 34.Rh6 Rxd5 35.Rxg6 Kc7 36.h4 Rh5 37.g3 d5 38.Ke3 Re5+ 39.Kd4 Re1 40.g4 Rd1+ 41.Ke3 d4+ 42.Ke2 Rb1 43.b3 Rb2+ 44.Kd3 Rxa2 45.Kxd4 Rd2+ 46.Kc3 Rh2 47.h5 Rh3+ White forfeited on time, Siggus - MetaMidi, FICS, 2006.

10.Qe2

Also improving on the previous 10.Qf3, e.g. Kf7 11.O-O Rf8 12.Qb3+ d5 13.exd5 Qxd5 14.Qxd5+ Nxd5 15.Nc3 Nb4 16.Rb1 Nxc2 17.b3 Bf5 18.Rb2 Nb4 19.a3 Nd3 20.Ra2 c6 21.a4 Rfe8 22.f3 Nxc1 23.Rxc1 Bd3 24.Raa1 Nf4 25.Kf2 Ne2 26.Nxe2 Rxe2+ 27.Kg3 Rae8 28.b4 Rxd2 29.b5 Ree2 30.bxc6 Rxg2+ 31.Kf4 g5+ 32.Ke3 Rge2+ 33.Kd4 bxc6 34.Kc5 Rc2+ 35.Rxc2 Rxc2+ 36.Kb4 c5+ 37.Ka5 Rb2 38.Rc1 c4 39.h3 Rc2 40.Re1 c3 41.Re5 Rb2 42.Rc5 c2 43.Rc7+ Kg6 44.Rc6+ Kh5 45.Rc3 Rb1 46.Rxd3 c1=Q 47.Rd5 Qc7+ 48.Ka6 Qb6 checkmate, indoeinstein - adlkaslad, FICS, 2014 

10...Kf7 11.O-O Re8 12.Nc3 



Curiously, the game has reached a position from the game featured in the previous post, with Black's Queen on d8 (here) instead of e6 (there).

Black's faulty combination now hands the advantage over to White. (He probably overlooked that the capture at move 14 comes with check.) When you are playing against a bad opening, it is easy to see its many faults, real and imagined.

12...Bg4 13.f3 Nxe4 14.fxe4+ Kg8 15.Qxg4 c6



White now settles things down with some exchanges, magnifying his extra piece and pawn.

16.d3 Qb6+ 17.Kh1 Rad8 18.b3 Ne5 19.Qg3 Re6 20.Bf4 Rg6 21.Qf2 Rf8 22.Qxb6 axb6 23.Bxe5 dxe5 24.Rxf8+ Kxf8 25.Rf1+ Ke7

The endgame plays out as expected.

26.g3 Ke6 27.Kg2 b5 28.Nd1 c5 29.Ne3 h5 30.h4 Rh6 31.Rf5 Rh7 32.Rg5 b6 33.Rg6+ Kf7 34.Rxb6 g6 35.Rb7+ Kg8 36.Rxh7 Kxh7 37.Kf3 Kg7 38.g4 Kf6 39.gxh5 gxh5 40.Nf5 Ke6 41.a4 bxa4 42.bxa4 Black resigned

A Familiar Line Off The Beaten Path

Image result for free clip art mail

I recently received 3 interesting and original games from "shugart" who plays online at FICS. In return, I was able to send him the latest version of The Database, which has been updated with FICS games through February 2016.

The following game features a line that shugart has shown a liking for.

shugart - javannanda
FICS, 2016

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 



7.Qd5+ 

"The nudge", a sign that the player may be familiar with the games and analysis of this blog.

7...Ke8 8.Qxc5 d6 9.Qb5+ 



Varying from the mundane 9.Qe3. This is a line that shugart has a lot of experience with.

9...Qd7

A couple of other lines that show up in shugart's play:

10.Qb3

He has also played 10.Qe2 Nf6 11.O-O Kf7 12.f4 Re8 13.Nc3 Qg4 14.Qc4+ Kf8 15.d3 Be6 16.Qxc7 Rac8 17.Qxb7 Kg8 18.f5 Nh4 19.e5 19...Bd5 20.Nxd5 Qxg2 checkmate, shugart - glemzy, FICS, 2013.

10...Qe6 11.Qe3 Nf6 12.Nc3 Kf7 13.O-O Re8



The game has reached the same position reached in shugart - transitman, lightning, FICS, 2013 (1-0, 29), and others, although in the earlier game Black's Queen was at e8.

14.f4 Qc4 15.d3 Qc5 16.d4 Qh5 17.e5 dxe5 18.fxe5 Kg8


White now puts a bit too much faith in his "Jerome pawns" with his next move - although things turn out fine in the end.

19.exf6 Rxe3 20.f7+ Kf8 21.Bxe3 c6 22.d5 Bg4



Not the best defense.

23.Bc5+ Ne7 24.Rae1 cxd5 25.Bxe7 checkmate

Caution!

It feels somewhat strange to urge caution in a chess opening that is known to be refuted - if the "best" lines still lose, what can be said of the "lesser lines"? Much seems to turn on "psychology", where the "best" move might be the most obscure or unclear or unsettling move - regardless of its "objective" worth - one that gives the opponent the greatest chance to go wrong.

So many times, the opponent takes that chance.

It is worth examining the play of HauntedKnight's games (as we have done before; see "Familiar Territory"), below, for ideas on how to pursue the attack.

HauntedKnight - blocbloc
FICS, 2016

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




4...Kxf7 5.Nxe5+ Nxe5 6.d4 



This move was, at first, Alonzo Wheeler Jerome's favorite response, although he later turned to 6.Qh5+.

6...Qh4

This is Black's sharpest response.

7.dxc5 

HauntedKnight has over 400 games in The Database, and he has scored 50%+ in them, so it feels a bit presumptious to suggest that he play the "better" move, 7.0-0, like he did previously:

7.O-O Ng4 8.h3 Bb6 9.hxg4 Nf6 10.g5 Ng4 11.Qf3+ Kg8 12.Qh3 Qxh3 13.gxh3 Bxd4 14.hxg4 d6 15.c3 Bb6 16.Kg2 Bxg4 17.f3 Bh5 18.Nd2 h6 19.Nc4 Bf7 20.Nxb6 axb6 21.gxh6 gxh6 22.Kf2 Kh7 23.Rh1 h5 24.Be3 Rhg8 25.b3 Rg7 26.Ke2 Rg2+ 27.Kd3 Raxa2 28.Rab1 Rh2 29.Rhg1 h4 30.Rg4 h3 31.Rh4+ Kg8 32.Bd4 Kf8 33.Rh8+ Ke7 34.Rh7 c5 35.Bh8 Ke8 36.Bf6 Rhd2+ 37.Ke3 h2 38.Rh1 Rg2 39.b4 cxb4 40.cxb4 Rae2+ 41.Kf4 d5 42.Rh8+ Kd7 43.exd5 Bxd5 44.Rh7+ Kc6 45.Bd4 Rd2 46.Rh6+ Kb5 47.Rxb6+ Kc4 48.Bc5 Rg1 49.Rxh2 Rxh2 50.Rxb7 Rh4+ 51.Ke5 Rh5+ 52.Kd6 Rg6+ 53.Kc7 Rh7+ 54.Kb8 Rxb7+ 55.Kc8 Rg8+ 56.Bf8 Rxf8 checkmate, HauntedKnight - scarlattibach, FICS, 2012.

7...Qxe4+ 8.Kf1 

This is an improvement over two other lines for White:

This is an odd idea, instead of continuing the attack with 18...Bb7. Perhaps Black miscalculated something. This is the kind of opportunity many Jerome Gambit players expect and enjoy.

19.Kg1 Nfg4 20.Qd2 

White should have continued to recover the piece with 20.Nf1 Qg5 21.Nxh2 Nxh2 22.Rxh2

20...Bb7 21.Qf4+ 

Still available was 21.Nf1

21...Kg8 22.Rxh2

A final oversight.

What Are You Playing?


The following quick game shows the risks of playing "thematically" instead of "concretely" - as in, not what your opening suggests, but what is actually on the board.

Wall, Bill - Guest3846778
PlayChess.com, 2016

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 

The Blackburne Shilling Gambit.

4.Bxf7+



The Blackburne Shilling Jerome Gambit.

4...Kxf7 5.Nxe5+ Ke6 6.c3 Qg5



I can imagine Bill thinking: "I'm playing the Jerome Gambit. What are you playing??" His opponent makes the thematic attacking move in the BSG, but he should have stayed in the main lines with 6...Kxe5.

I was surprised to find 52 games in The Database with this position, with White scoring 61%. Only 39 games feature White's next move, which bumps the scoring up to 65%. Sadly, 37 games feature Black's terminal response - and White still scores only 64%.

This game shows the way to a full 100%.

7.cxd4 Qxg2

As intended, but allowing checkmate. 

8.Qb3+ Kd6 9.Qd5+ Ke7 10.Qf7+ Kd6 11.Nc4+ Kc6 12.Qd5 checkmate
