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.

Jerome Gambit Doctor


Periodically in this new year we will be looking at different lines in the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) and be providing ideas (and study material) which may deliver "first aid" or heavier "fixes" in situations where White's play has been injured.

Here is a game by HauntedKnight, a regular player of things Jerome. He has 144 games in The Database, scoring an over-all 49%, which is the over-all average for White in those 27,400 games. With the Jerome Gambit proper he scores 42%, which is comparable to the 43% of all Jerome Gambit games in The Database.


HauntedKnight - Josue

standard game, FICS, 2012

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.d4 Be7 




Josue, the higher-rated player, chooses a very reasonable, if unpopular line. The Database has only 12 games with this move, but White has scored only 38% against it.


7.dxe5


White avoids the ostentatious 7.f4 which brings a lot of visual excitement, but more "flash" than "bang": 7...Nc6 8.d5 Nb4 9.a3 Na6 10.0-0 Nf6 11.e5 Ne8 12.Qh5+ g6 13.Qh6 Bf8 14.Qh3 d6 15.e6+ Kg7 16.b3 Be7 17.f5 Nf6 18.Bb2 c6 19.c4 cxd5 20.Nd2 dxc4 21.Ne4 Nc5 22.Nxf6 Bxf6 23.Bxf6+ Qxf6 24.bxc4 b6 25.Qg3 Bb7 26.Qxd6 Rad8 27.Qf4 Rd4 28.Qe3 Re4 29.Qd2 Rd8 30.Qf2 g5 31.Rad1 Red4 32.Qf4 Rxf4 White resigned, wirerabbit - SimpleOne, FICS, 2007

9...Nh6


Black is planning something wicked, a threat that shows up in several of the above games. Probably his best move was 9...dxe5.


10.Nc3 


It is prudent to note here that White can take the draw with 10.Bxh6 gxh6 11.Qh5+ Kf8 12.Qf3+ Kg7 13.Qg3+ Kf7 14.Qf3+ Kg8 15.Qb3+ Kg7 16.Qg3+ Kf7, etc.


If White wants to play on, it would seem that 10.Qh5+ Nf7 11.exd6 followed by 12.Nc3 would be best.


10...Bg4 


The unhappy point: White will lose his Queen.


11.Qg3 Bh4 12.Qf4 Rf8 13.Qxf8+ Kxf8 




White continued the fight, but it was too much. 


14.g3 Bg5 15.f4 Be7 16.Kf2 Qe8 17.h3 Bd7 18.Ke2 dxe5 19.fxe5 Qh5+ 20.Kd2 Bg5 21.Rae1 Bxe3+ 22.Rxe3 Qxe5 23.Kc1 Kg8 24.Rd1 Bxh3 25.Rd5 Qf6 26.b3 Rd8 27.Rc5 Qf2 28.Nd5 Rxd5 29.Rec3 Rxc5 White resigned

A Successful Tournament Already

In the first of my two Italian Game tournaments at Chess.com I have won one game and am near another win. Both of them are technical endgames.


In my second tournament, I suffered a loss when my "brilliant" Queen sacrifice did not lead to a back rank checkmate, after all... Awkward.


However, I have just completed a win with the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+), and that is enough for me to consider the tournament a success, already!


perrypawnpusher (1636) - Vaima01 (1773)

Italian Game - Round 1 Chess.com, 2012


1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 




This is a natural response, prudently returning one of the two sacrificed pieces; yet, I am always glad to see it, as it leads to interesting clashes between the "Jerome pawns" and Black's extra piece, and the chess engines usually show a gradual slip into an even game after about a dozen moves.


7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Qe7 




10.Nc3


Or 10.d4, as in mrjoker - lilred, ICC, 2009 (1-0, 50); or 10.0-0 as in mrjoker - blind25, ICC, 2009 (0-1, 66) and perrypawnpusher - Edvardinho, blitz, FICS, 2010 (1-0, 57).


10...Nf6 11.0-0 Be6


A bit more active was 11...Rf8, as in perrypawnpusher - MRBarupal, blitz, FICS, 2010 (0-1, 31) and perrypawnpusher - chingching, blitz, FICS, 2011 (½-½, 36).

An alternate development of Black's Bishop was seen after 11...b6 in perrypawnpusher - Navarrra, blitz, FICS, 2011, (1-0, 24).

12.f4 Bf7 


Black's move is sensible. There have been a variety of alternatives:


The frisky 12...Bc4 was seen in  perrypawnpusher - ZhekaR, blitz, FICS 2011 (0-1, 36) and perrypawnpusher - tuffnut, blitz, FICS, 2012 (1-0, 62); 


The retreat 12...Bd7 appeared in perrypawnpusher - Unimat, blitz, FICS, 2011 (1-0, 25); 


The bold 12...Kd7 was tried in perrypawnpusher - Solaar, blitz, FICS, 2011 (33); and

The counter-attacking 12...Ng4 erupted in Wall,B - Hirami,Z, Chess.com, 2011 (1-0, 20). 


13.f5 Ne5 14.d4 Nc6 15.Qd3 Kd7 16.e5 Ne8 




Black opts for the scientific solution of returning a piece for two pawns, with the goal of leveling out the position and the game.


After the game, however, Rybka suggested the way to do that would have been by 16...Nxe5 17.dxe5 Qxe5. It turns out that there is a glitch or two in giving back the Bishop.


17.e6+ Bxe6 18.fxe6+ Kd8


The second pawn is not easily taken, as after 18...Kxe6 there is 19.Qf5 checkmate; and after 18...Qxe6 White has 19.d5.


White is now better, but it took me a while to figure out how to proceed.


19.d5 Ne5 20.Qf5 h6 21.Bf4 Rf8 22.Qh3 Rf6 




This helps, although in the end I decided to settle for the win of another pawn, with a strong position.


23.Ne4 Rf8 24.Bxe5 dxe5 25.Qg3 Nf6 26.Qxe5 




26...Nxe4 27.Qxe4 Qc5+ 28.Kh1 Ke7 29.Rf7+ 




My favorite move of the game. It's success is based on finding a "quieter" move later on.


29...Rxf7


After the alternative, 29...Ke8, I had planned 30.Raf1 and Black does not have long to live.


30.exf7+ Kxf7


I was happy to see that after 30...Kf8 I would have the nice move 31.Re1 


31.Qe6+ Kf8 32.Rf1+ Qf2 Black resigned

If A Tree Falls...



If a tree falls in the forest, and there is no one around to notice, does it make a sound? 

Is a bad move in chess a blunder, if it never is punished?



 perrypawnpusher - tuffnut
blitz, FICS, 2012

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


Before this game tuffnut had 7 wins, 6 losses, and a draw against the Jerome Gambit.

4...Kxf7 5.Nxe5+

An exciting alternative was seen in workingdead - tuffnut, FICS, 2011 5.b4 Bxb4 6.c3 Be7 7.d4 exd4 8.cxd4 d6 9.0-0 Bg4 10.Qb3+ Ke8  although Black prevailed in 72 moves.

On the other hand, the specious 5.Ng5+ earned a split decision against my opponent in three games: carlbecker - tuffnut, FICS, 2005 (½-½, 69); neni - tuffnut, FICS, 2009 (1-0, 7); and Lommel -tuffnut, FICS, 2010 (0-1, 15).

Like the above, I would hardly have known until my research, after our game was over, that my opponent had also dispatched 5.d4 (Handlangari - tuffnut, FICS, 2005, 0-1, 22) and 5.d3 (pettypete - tuffnut, FICS, 2004, 0-1, 21).

5...Nxe5 6.Qh5+

It turned out afterward that my opponent was only 1-3 against 6.d4, but that is a move that I do not play.

6...Ng6

A number of years ago, perrypawnpusher - tuffnut, blitz, FICS 2007 saw 6...g6 (1-0, 33).

7.Qd5+

The "nudge".

Later, I chuckled to note that my opponent was 2-0 against the "pure" 7.Qxc5.

7...Ke8 8.Qxc5 d6 9.Qe3 Qe7


10.0-0 Nf6 11.Nc3

Or 11.d3 as in perrypawnpusher - Edvardinho, blitz, FICS, 2010 (1-0, 57). (Hmmmm, it looks like I have never posted this game - Rick.)

11...Be6

Not overlooking the possible pawn fork, but planning to put pressure on White's center and his Rook at f1.

Either 11...Rf8 (e.g. perrypawnpusher - MRBarupal, blitz, FICS, 2010, 0-1, 31) or 11...Kf7, looking to castle-by-hand, could be a bit stronger.

12.f4 Bc4 13.d3 Ba6 14.Bd2 b6


15.Rae1 Kd7 16.Qh3+ Kd8 17.g4


Searching for an improvement over 17.Nd5 of perrypawnpusher - ZhekaR, blitz, FICS 2011 (0-1, 36), but this is not it.

After the game Rybka preferred 17.e5 dxe5 18.fxe5 Nd7 but I don't think that I would have seen the followup 19.Ne4, leading to an edge for White.

17...Bc8 18.f5 Ne5 19.g5 Ne8 20.Qg2 Qd7 21.f6


With Black's King and pieces huddled in the middle of the board, it looks like the ideal time to open things up, but White ignores the dangers to his King and Queen along the g-file. 20.d4, with the idea of e4-e5 was a better way.

21...gxf6 22.gxf6 Qf7 23.Bg5

Instead of this move (and for the next few moves) Rybka's post-game analysis focuses on 23.Re3, so that White will have some kind of an answer to Black's ...Rg8.

23...Be6


24.b3 c6 25.Kh1 Kc7 26.d4 Ng6 27.e5 dxe5 28.dxe5 Bd5



In blitz, you can sometimes not see something that is there (like the threats along the g-file), and then see something that is not there.

I don't know if tuffnut thought that he was pinning and winning my Queen with this move, or if he decided that his extra piece would give him the advantage with Queens off of the board; but, suddenly, my "Jerome pawns" can spring to life. 

29.Nxd5+ Qxd5 30.Qxd5 cxd5 31.h4


More straight-forward was 31.f7.

31...h6 32.Bf4 Nxf4 33.Rxf4 Kc6

Better was 33...Rf8 right away, with plans to include the Rook in a blockade of the pawns.

34.e6 Nd6 35.f7 Rhf8


36.e7 Rxf7 37.Rxf7 Nxf7 38.e8Q+ Rxe8 39.Rxe8 Nd6


White's "Jerome pawns" have disappeared, by they have taken their toll: White is up the exchange. Further, his h-pawn will cost Black his Knight.

Can Black's King advance and cause problems on the Queenside?

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.

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.

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.

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

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.
