Staring It Down



In the following game White plays 6.d4 and is immediately hit with the strongest reply, 6...Qh4. Time to panic? Hardly. Simply time to stare the defender right in the eye and ask him: Okay, that's one good move, do you know what comes next?? 


Darthnik - aufdermaur
blitz, FICS, 2011

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


4...Kxf7 5.Nxe5+ Nxe5 6.d4 Qh4


A full-bore response to White's center play. For recent comments, see "Deus Ex Machina" and "Danger? He Laughs At Danger".

7.0-0 Ng4

Black has mate on his mind, and directs his pieces accordingly. 

8.h3 Bd6

Consistent, but 8...Bb6, as in Sir Osis of the Liver - perrypawnpusher, JG3 thematic, ChessWorld, 2008 (0-1, 38) and Wall,B - Rajiv, Chess.com, 2010 (1-0, 33) was probably stronger.

9.e5 Nxe5

Black decides to return a piece for two pawns, to keep the initiative. This may be a slight improvement upon the similarly intentioned 9...Bxe5 which was played in the earliest (to The Database's knowledge) 6...Qh4 game, Sorensen,S - X, Denmark,  1888, (1-0, 27).

Perhaps the patient 9...Be7 was better, still.

10.dxe5 Bxe5


11.f4

A very understandable move from a psychological perspective: White's King has been facing a three-piece onslaught in which Black was comfortable enough to burn one of his own pieces (why not, he still has an extra one) to keep things going. This feels unfair, as White chose the Jerome Gambit to have an attack on Black's King, not the other way around.

White's move blunts the impact of the Bishop, but he had more to expect from 11.Qd5+ putting the focus back on the Black monarch. If Black does not want to simply give a second piece back then he has to try 11...Kf6.

The equalizer for White, then, would be 12.Nd2, intending Ne4+, kicking the protection away from Black's Bishop. Simple development for Black, like 12...Ne7, would even allow the fork trick 13.Qxe5+ Kxe5 14.Nf3+ followed by 15.Nxh4 and material equality. Hanging onto the Bishop for dear life with 12...Qd4, instead, would lead to complications after 13.Qf3+ Ke7 14.Re1, but, again, White will recover his sacrificed piece.
White works this all out a move too late.

11...Bd6 12.Qd5+ Kf8 13.Nd2 Nf6


Now White has to work his attack up all over again. He can be satisfied that Black's "attacking" Bishop has become his "blocking" Bishop, as in blocking Black's own development.

14.Qd3 b6 15.Ne4 Bb7 16.Nxd6 cxd6 17.Qxd6+ Kf7 18.Qd3 Rhe8 19.Bd2 Kg8

The theme looks like it is about to change. Black has castled-by-hand and can look toward attacking White's King again (with an extra piece).

20.f5 Nh5 21.Bc3 Nf4

Aggressive, sure, but overlooking White's counter.

22.Qc4+

This double attack wins back the sacrificed piece. More than that, it seems to distress Black, who again sees his Kingside attack dissolve.

22...Kh8

This move whispers "King safety" but it should have been replaced with 22...d5, since after 23.Qxf4 Qxf4 24.Rxf4 Black can still look toward the drawing chances of a possible Bishops-of-opposite-colors endgame.

Now White's attack roars on.

23.Rxf4 Qh6 24.Rg4 Rg8 25.f6


Thematic, but 25.Re1, planning Re7 with even more pressure on g7, was even stronger.

25...g6 26.f7+ Rg7 27.Qb4 d5 28.f8Q+ Rxf8 29.Qxf8 checkmate


And that, good Readers, is how Darthnik faced the refutation, looked right into its eyes, and stared it down...

Between the Refutation and the Resignation...Part 1

I've mentioned the discussion going on at Chess.com about the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+). Some find it to be an interesting opening, some find it to be a poor one.

Jerome Gambit Gemeinde (and Chess.com) member Bill Wall has been positive about possible uses of the gambit ("it's the type of opening I like in blitz chess and I have had fun and success with it. My success this year has been 18 wins, 1 draw, and 1 loss").

Chess.com Kacparov has been more skeptical ("The Jerome gambit can be easily refuted."). 

Both are relatively strong club players, and I'd like to present a Jerome Gambit game by each.

Wall - Rajiv

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


4...Kxf7 5.Nxe5+ Nxe5 6.d4 Qh4


The Nibs Variation, which received a serious look in the series "Repairing a Variation (Part 1)", "(Part 2)", "(Part 3)" and "(Part 4)". It is a wild, but dangerous, refutation.

Between the refutation and the resignation, however, the chess gods have placed the middle game (and sometimes the endgame).

7.0-0 Ng4

This is the traditional move, although Wall has also met 7...Qxe4, recommended by Rybka: 7...Qxe4 8.dxc5 Nf6 9.Nc3 Qc6 10.Re1 d6 11.cxd6 Qxd6 12.Bf4 Nf3+ 13.Qxf3 Qb6 14.Nd5 Nxd5 15.Bxc7+ Qf6 16.Qxd5+ Be6 17.Qxb7 Rhe8 18.Bd8+ Black resigned, Wall - Gorodetsky, Chess.com, 2010 

8.h3 Bb6


9.hxg4

Less successful was 9.Qf3+ N4f6 10.e5 Bxd4 11.exf6 Nxf6 12.c3 Bb6 13.Nd2 Rf8 14.Ne4 Qxe4 15.Qd1 d5 16.Re1 Qf5 17.Be3 Bxe3 18.Rxe3 Bd7 19.Rf3 Qe5 20.Qd2 Rae8 21.Re3 Qd6 22.Rxe8 Rxe8 23.b3 Qe5 24.Rf1 Bc6 25.Kh1 Qe2 26.Qc1 d4 27.cxd4 Qe4 28.d5 Qxd5 29.f3 Kg8 30.Rd1 Qe6 31.Qf4 Nd5 32.Qd4 Ne3 33.Rc1 Bxf3 34.Kg1 Nxg2 35.Rxc7 Qe3+ 36.Qxe3 Nxe3 37.Kf2 Bc6 38.b4 Nd5 White resigned, Sir Osis of the Liver - perrypawnpusher, JG3 thematic, Chessworld.net, 2008.

9...d6 10.f3 Be6


11.Be3 Bc4 12.Re1 Ne7



13.f4

The "Jerome pawns".

13...Rhe8 14.Nd2 Ba6 15.Nf3 Qg3


16.a4 Ba5 17.c3 Kf8 18.b4 Ng6


19.f5 Nf4 20.Bxf4 Qxf4 21.Qc2 c5


White seems to be holding on remarkably well, given that his opening has been refuted.

22.bxa5 Qxg4

I asked for Rybka's input on how the game was going, and I received it in a series of evaluations that looked like increasing pressure readings in a boiler that is about to blow up. Here White was rated 2.04 pawns ahead.

23.Rad1 cxd4

2.61 pawns 

24.Rxd4 Qg3 25.Qb3 Qf4


3.67 pawns

26.Qb1 Qg3

5.04 pawns

27.e5 g6

8.72 pawns.

28.Rxd6 Re7

12.28 pawns

29.f6 Ree8


From this position White can see mate. 

30.Qb4 Bb5 31.Rd8+ Kf7 32.e6+ Kxf6 33.Qd4+ Black resigned
