What A Difference A D(el)ay Makes


I puzzled my way through the following game, even though I didn't need to. It is Bill Wall playing the Jerome Gambit. Of course White wins.

Wall,B - PLKT

FICS, 2013

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6 


Heading for the Blackburne or Whistler Defenses.


7.Qxe5 Bd6 

8.Qd5+

I was puzzled by this move, as experience has shown that after this inaccurate move (better 7...d6 or 7...Qe7) the Black Rook can be taken: perrypawnpusher - tuffnut, blitz, FICS, 2007 (1-0, 33); perrypawnpusher - bakker, blitz, FICS, 2008 (1-0, 20); perrypawnpusher - Kapppy, blitz, FICS, 2009 (1-0, 34); perrypawnpusher - Sirenus, blitz, FICS, 2010 (1-0, 13); perrypawnpusher - frencheng, 7 5 blitz, FICS, 2010 (1-0, 17); and perrypawnpusher - elyza, blitz, FICS, 2010 (1-0, 24);


Furthermore, Bill is always the first to examine the latest version of The Database and mine it for new ideas to inject into his games.


Plus, he has read the almost 1,750 posts here on this blog.


That last fact gave me a thought: with all that information, could a couple of lines of play have been crossed in his mental database? It turns out, that's quite possible.


Looking back at "By the Numbers" (see also "Pulling A Rabbit Out of A Hat" and "I think I have a win, but it will take time...") there is a game similar to today's, coming out of the Semi-Italian Jerome Gambit opening (add 0-0 for White and ...h6 for Black), where the notes indicate that the defender should have played ...Bf8!? instead of that game's ...Bd6, as then the Rook would be poisoned.


Or, maybe this is all just a lot of psychological noodling on my part.


8...Kf8 9.d4 Nf6 


10.Qg5 Be7 11.Qe3 d5 12.e5 Ne4 




White has his standard two pawns for a piece, while both Black's Knight and King could prove misplaced.


13.0-0 Bg5 14.f4 Bh6 15.h3 Qh4 16.Nc3 Nxc3 17.bxc3 Bf5




Black continues his aggressive play. Perhaps he is familiar with Blackburne's destruction of the Jerome Gambit?


18.c4 c6 19.Ba3+ Ke8


It may not be immediately obvious, but getting the King off of the f-file by moving him into the center is not best.


White can now generate enough excitement to even the game up - or to go for more, if his opponent cooperates.


20.Qb3


Quite possibly this is just the move Black had been hoping for. While he lines up his two Bishops and Queen to find a Blackburne-like mating attack, his opponent's strong piece abandons her monarch.


20...Bxf4


Too hopeful. His Queen had to return home, while giving up material - 20...Qd8 21.Qxb7 Rc8 22.Qxa7 dxc4 - with about an equal game.


21.Qxb7


Bill points out that White has to plunge ahead, as 21.Rxf4? Qxf4 22.Qxb7 Qxd4+ 23.Kh2 Qxe5+ is a terrible alternative.


Now Black has the opportunity to "sacrifice" both of his Rooks, as in the Blackburne game - but without getting the requisite mating attack.


21...Be3+


Best, but not saving.


22.Kh2


The only move. Certainly not 22.Kh1 Bxh3 23.Qxa8+?? Bc8 checkmate.


22...Bf4+ 


It was time for Black to go for the swindle with 22...Bxh3 23.Qxa8+?? Bc8 checkmate!  


Instead, 22...Bxh3 23.gxh3? would have led to a draw by perpetual check 23...Bf4+ 24.Rxf4 Qxf4+ 25.Kg2 Qe4+, etc.


Of course, after 22...Bxh3 23.Qf7+! Kd8 24.gxh3 all is good with White's world.


23.Rxf4 Qxf4+ 24.Kh1 Qh4 25.Qxa8+ Qd8 26.Qxc6+ Kf7 27.cxd5 Black resigned


In the end, even the "Jerome pawns" joined in the attack.

Complications


My opponent was a bit overwhelemed by the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) in this game, but like with yesterday's post (see "Crushed") there were some very interesting options available to the losing player.


perrypawnpusher - Sirenus
blitz, FICS, 2010

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


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6


7.Qxe5 Bd6


Save the Bishop, attack the Queen, sacrifice the Rook...

It's an interesting plan, but unfortunately it doesn't work here. Either the Blackburne (7...d6) or Whistler (7...Qe7) defenses effectively meet Black's goals, though.

8.Qxh8 Qh4


Energetic! I've had three games continue differently:

8...Qg5 9.Qxh7+ Kf6 10.Qxg8 Qxg2 11.Rf1 Qxe4+ 12.Kd1 b6 13.Qh8+ Kf5 14.Qh3+ Kf6 15.Nc3 Qe5 16.Qf3+ Kg7 17.Qxa8 Qh5+ 18.f3 Ba6 19.d3 Qxh2 20.Qe4 Qg2 21.Qe2 Qg3 22.Ne4 Qh4 23.Nxd6 cxd6 24.Re1 Black resigned, perrypawnpusher - elyza, blitz, FICS, 2010;


8...Ke6 9.Qxh7 Ne7 10.d4 c5 11.d5+ Ke5 12.Nc3 Kd4 13.Be3+ Kc4+- 14.0-0-0 Be5 15.Bd2 Qb6 16.Qh3 d6 17.Qd3+ Kb4 18.a3+ Ka5 19.Qc4 Bxc3 20.Bxc3+ Black resigned, perrypawnpusher - bakker, blitz, FICS, 2008; and


8...Be7 9.Qxh7+ Kf8 10.Qxg6 d6 11.d4 Bd7 12.Bh6+ Nxh6 13.Qxh6+ Kf7 14.Qh7+ Kf8 15.Qh8+ Kf7 16.Qxd8 Rxd8 17.Nc3 c6 18.0-0 Rg8 19.f4 Bh3 20.Rf2 Bd7 21.e5 dxe5 22.dxe5 Ke8 23.f5 Bc5 24.f6 Bxf2+ 25.Kxf2 Be6 26.Ne4 Rf8 27.Nd6+ Kd7 28.Rd1 Kc7 29.h3 Bd5 30.g4 Rh8 31.Kg3 b6 32.h4 Be6 33.g5 Black resigned, perrypawnpusher - tuffnut, blitz, FICS, 2007.

9.Nc3

Protecting the e-pawn, but 9.d3 was better for that. Then, after 9...Qh5 White can withdraw his Queen with 10.Qc3.

After 9.d3, then 9...Nf6 doesn't quite work, as White can quickly move his own Knight into play: 10.Nd2 b6 (planning 11...Bb7) 11.Nf3 attacking Black's Queen first.

Black can still complicate things after 9.d3 Nf6 10.Nd2, though, with 10...Ng4, as White's best is to allow the check/capture at f2, playing 11.Nf3 Qxf2+ 12.Kd1.





analysis diagram






White's King is uncomfortable, but his Queen will make things even more difficult for Black's King.

So, even with my "better" move, Black could have stirred things up.

Complications!

9...Be5

A simple oversight.

Again, White is better after 9...Nf6, but not without some thought and work. Best would be 10.d4, but Black's plan to win the cornered White Queen would take some creativity to defeat.





analysis diagram




For example, 10...b6 11.e5 Be7 12.Bg5!? jailbreak's the Queen after 12...Qxg5 13.exf6 Bxf6 14.Qxh7+ and White's initiative, safer King and material advantage should win.

Or, Black could try 10...Be7 first (after 9...Nf6 10.d4), with more complications after 11.e5 Ng4 12.g3 Qh3 13.Nd5 b6 14.Nxc7 Bb7 15.Nxa8 Bxh1 16.Nc7 Bf8 (the White Queen is still trapped) 17.Bd2 Qxh2 18.0-0-0 and at least White's King has escaped the heat...

Complications!

The text move, however, solves all of White's problems.

10.Qxe5 d6 11.Qg3 Qxg3 12.hxg3


12...Be6 13.Rxh7+ Black resigned

Is a Draw Good Enough Against the Jerome Gambit?

If you are playing the Black pieces and are facing the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), is a draw a favorable outcome for you? In my experience, my opponents would respond with a resounding "No!" – despite the fact that I have scored 85%+ with the opening.

In the following game my opponent quickly reached a worse position. My sloppiness allowed a draw by repetition – which would have been a fair result for both of us.

Instead, my opponent sought more – and found less.

perrypawnpusher - elyza
blitz FICS, 2010

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


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ g6


This can lead to either the Blackburne (7.Qxe5 d6) or Whistler (7.Qxe5 Qe7) Defenses.

7.Qxe5 Bd6


This is kind of a "semi-Blackburne" defense, the kind of thing that I fussed about in "Half a defense is worse than none at all...".

The updated New Year's Database gives 25 previous games, with White scoring 88%.

The successful 6...g6 defense relies on a blistering attack on White's King (and possibly trapping White's Queen) to offset the loss of the Rook. That doesn't happen after 7...Bd6.

8.Qxh8 Qg5


After the game, Rybka recommended 8...Qh4 9.d3 Qh5 10.g4 Qh3 11.g5 b6 12.Be3 Ba6 13.Nd2 Rf8 14.Qc3 Ne7 with advantage to White as his Queen has escaped, his King will soon castle, and he has a material edge.


 


analysis diagram







Two previously unsuccessful tries for Black were: 8...Be7 9.Qxh7+ Kf8 10.Qxg6 d6 11.d4 Bd7 12.Bh6+ Nxh6 13.Qxh6+ Kf7 14.Qh7+ Kf8 15.Qh8+ Kf7 16.Qxd8 Rxd8 17.Nc3 c6 18.0-0 Rg8 19.f4 Bh3 20.Rf2 Bd7 21.e5 dxe5 22.dxe5 Ke8 23.f5 Bc5 24.f6 Bxf2+ 25.Kxf2 Be6 26.Ne4 Rf8 27.Nd6+ Kd7 28.Rd1 Kc7 29.h3 Bd5 30.g4 Rh8 31.Kg3 b6 32.h4 Be6 33.g5 Black resigned, perrypawnpusher - tuffnut, blitz FICS, 2007; and

8...Ke6 9.Qxh7 Ne7 10.d4 c5 11.d5+ Ke5 12.Nc3 Kd4 13.Be3+ Kc4 14.0-0-0 Be5 15.Bd2 Qb6 16.Qh3 d6 17.Qd3+ Kb4 18.a3+ Ka5 19.Qc4 Bxc3 20.Bxc3+ Black resigned, perrypawnpusher - bakker, blitz FICS, 2008.

9.Qxh7+ Kf6 10.Qxg8


Grabbing the extra piece, but simpler was 10.0-0 Nh6 11.d4 b6 12.Bxg5+ Black resigned, MariaTavares - PeterPygmalion, FICS, 2005

10...Qxg2 11.Rf1


This was a knee-jerk reaction, almost as fast as my capture of the Knight – and it could have had unhappy consequences.

The fact is – in a reversal of roles from the Blackburne or Whistler defenses – White is in position to give up his Rook and focus on bringing danger to Black's King with: 11.Nc3!? Qxh1+ 12.Ke2.




analysis diagram







Black's best move now is 12...c6, keeping White's Knight off of d5, although like all the other choices it will lead to checkmate (starting with 13.d4).

11...Qxe4+ 12.Kd1


12...b6

It was wisest to split the point: 12...Qf3+ 13.Ke1 Qe4+ 14.Kd1 etc., repeating the position.

13.Qh8+ Kf5 14.Qh3+ Kf6


15.Nc3 Qe5 16.Qf3+ Kg7 17.Qxa8


17...Qh5+ 18.f3 Ba6 19.d3 Qxh2 20.Qe4 Qg2 21.Qe2


White's King is safe, the extra material will tell.

22...Qg3 22.Ne4 Qh4 23.Nxd6 cxd6 24.Re1 Black resigned

Tied Up, or How Much Is A Queen Worth?

There's nothing like receiving the gift of your opponent's Queen in the first twelve moves of a game, especially when you are in a critical line of one of the Jerome Gambit's (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) refutations.

Why, it only took me 32 more moves to end the game!

Huh?

perrypawnpusher  - elyza
blitz FICS, 2009

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6


This is one of the classical refutations of the Jerome Gambit.

Modern players unfamiliar with the Jerome may prefer 6...Ng6, 6...Kf8 or 6...g6 because this line feels more dangerous, but the King is actually safe in the middle of the board – and Black has two extra pieces, as well.

My first conclusion about my opponent, who was playing without much hesitation: he either doesn't like to return material, or he knows what he is doing.

7.Qf5+ Kd6 8.f4 Qh4+


Ah, yes, the "Nibs" defense – or counter-attack, if you will. It's beginning to look like my opponent elyza has stopped by this blog a time or two.

9.g3 Nf3+

Wow! Seriously cutting-edge play. For some background, check out "Repairing a Variation (Part 1), (Part 2), (Part 3) and (Part 4)".

10.Kd1
If you are going to battle the Queen-sac line, I think 10.Kd1 is the right move. If you are looking toward the endgame, 10.Kf1 is to be preferred – "Repairing a Variation (Part 4)"
The alternative: 10.Kf1 Qh6 (10...Qf6 11.Qd5+ Ke7 12.Qxc5+ Kd8 13.Kg2 d6 14.Qd5 Ne7 15.Qd3 Nd4 16.e5 dxe5 17.c3 Bf5 18.fxe5 Qc6+ White resigned, perrypawnpusher - james042665, Chess.com, 2008) 11.Qd5+ Ke7 12.Qxc5+ Qd6 13.Qxd6+ cxd6 14.c3 g5 15.Kf2 g4 16.h3 d5 17.hxg4 dxe4 18.d3 d5 19.g5 h6 20.dxe4 dxe4 21.Nd2 Nxd2 22.Bxd2 Bg4 23.Be3 Ke6 24.Rh4 Kf5 25.Bd4 Rh7 26.Rah1 h5 27.Ke3 Ne7 28.R4h2 Nd5+ 29.Kd2 b6 30.Re1 Re8 31.Be3 Rd8 32.Kc2 Rc7 33.a3 Rcd7 34.Bd4 b5 35.Be5 Rc8 36.Kb1 a5 37.g6 b4 38.axb4 axb4 39.g7 b3 40.Bd4 Kg6 41.Kc1 Kf5 42.Rhh1 Nb4 43.Kd2 Rxd4+ White resigned, perrypawnpusher - Temmo, JG3 thematic, Chessworld, 2008.

10...Qf6

Or 10...Qh6 11.Qd5+ Ke7 12.Qxc5+ Qd6 13.Qxd6+ cxd6 14.c3 Nf6 15.d3 b6 16.Ke2 d5 17.Kxf3 dxe4+ 18.dxe4 Bb7 19.Re1 Kf7 20.Nd2 Rhe8 21.g4 d5 22.e5 d4+ 23.Kg3 dxc3 24.bxc3 Nd5 25.Bb2 Rad8 26.Ne4 Nf6 27.Nd6+ Kf8 28.Nxb7 Rd7 29.Ba3+ Kf7 30.Nd6+ Rxd6 31.exd6 Ne4+ 32.Rxe4 Rxe4 33.Kf3 Rc4 34.d7 Rxc3+ 35.Ke4 Black resigned, perrypawnpusher - electrahan, blitz FICS, 2009

11.e5+

Fail.

This looked like a great move at the time, but the right path had already been laid out for me by Louis Morin ("mrjoker"), that of simply collecting the dark-squared Black Bishop: 11.Qd5+ Ke7 12.Qxc5+ d6 13.Qxc7+ Bd7 14.Nc3 Rc8 15.Nd5+ Ke6 16.Qxb7 Qd4 17.f5+ Ke5 18.Qxd7 Nf6 19.Qe6 checkmate, guest2365 - guest2535, Internet Chess Club, 2004

11...Ke7

Wow.

Black was taken in by the move, too. Had he played, instead, 11...Nxe5 12.fxe5+ Qxe5 he would have shown that my pawn advance was a blunder.

12.exf6+ Nxf6


Game over? Hardly. My opponent probably wants me to show him that I have more than just a good sense of humor in the opening. Or maybe he is aware that sometimes I get... tired.

13.Qxc5+ d6 14.Qe3+ Kf7


15.h3

Naturally not 15.Qxf3 Bg4 winning the Queen.

15...Nxd2 16.Bxd2 Re8


17.Qf2 Kg8 18.Re1 Bxh3


I don't mind giving up the pawn. I'm trying to untangle my pieces on the Queenside.

19.Nc3 Bg4+ 20.Kc1 c5 21.b3 b5 22.Kb2 b4 23.Ne2 Ne4


This is getting annoying.

24.Qe3 a5 25.Qd3 a4 26.Ng1 a3+ 27.Kc1


27...Rad8

I was getting frustrated. Being this tied up was ridiculous!

28.c4

This is not a BLUNDER, but it is clearly an INACCURACY – see "Italian Game Anti-Fried Liver Defense (Part 2)" – since 28.Rxe4 was the best move. (Would it have ended the game? Probably not.)

Here is my new annotation for "I should have had some coffee":


28...Nf2 29.Rxe8+ Rxe8 30.Qxd6 Ne4


31.Qd5+ Be6

A slip. It helped.

I knew that I was going to have to go all the way to checkmate with my opponent, though, and time was running low.

32.Qxe4 Bf7 33.Qg2 Bh5 34.Kc2 Bg6+


35.Kd1 Be4 36.Qf2 Bf5 37.Nf3 Bg4


38.Be3 Rd8+ 39.Ke1 Rd3 40.Rd1


At last!

40...Rc3 41.Rd8+ Kf7 42.Ne5+ Ke7 43.Qd2 Bf5 44.Qd6 checkmate
