Overlooked For A Reason


Here's that "overlooked" Jerome Gambit game that I mentioned in my last post, "Another Error, Another Win". It's a painful one to play over, as my opponent offered me an escape from a difficult situation, and I missed it.

perrypawnpusher - alvarzr
blitz, FICS, 2013

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 7.Qd5+ Ke8


8.Qxc5 Qe7 9.Qe3 Nf6 

Or 9...d5 as in Wall,B - Guest497592, PlayChess.com, 2012 (1-0, 23). 

10.Nc3 d6 

Or 10...Kf7 11.0-0 Rf8  as in perrypawnpusher - frencheng, 20 5 blitz, FICS, 2010 (½-½, 34). 

11.0-0 b6 

Instead, Black got more aggressive with 11...Be6 12.f4 Ng4 13.Qg3 Qh4 in Wall,B - Hirami,Z, Chess.com, 2011 (1-0, 20) and with 
11...Ng4 in Wall,B - CKSP, FICS, 2010 (1-0, 15); but more careful (castling-by-hand) with 11...Rf8 12.f4 Kf7  in  perrypawnpusher - chingching, blitz, FICS, 2011 (½-½, 36). 

12.f4 Bb7 13.d3 

The more forward 13.f5 Ne5 14.d4 followed in perrypawnpusher-Navarrra, blitz, FICS, 2011 (24) and perrypawnpusher - MarkHundleby1, Chess.com, 2013 (1-0, 27).

13...Kd7 

Or 13...a6 14.b3 Kd7 15.Ba3 Rae8 as in perrypawnpusher -MRBarupal, blitz, 2010 (0-1, 22) 

14.Bd2 

A bit better was 14.Qh3+ Ke8 15.b3

14...Rae8 15.Rae1 Rhf8 

One of the reasons that I have shared a lot of links above is to show how many ideas grow out of these Jerome Gambit positions. In the current game, however, as things went on, I began to think less and push pieces more, and this is never a good thing.

16.Qd4 Kc8 17.Qa4 Nd7 18.Qxa7 Nc5 19.Qa3 

Pawn grabbing with the Queen is not such a deep idea. Instead, it was time to be more dynamic with play like 19.b4 Na6 20.b5 Nc5 21.f5 Nh8 22.Nd5. 

19...Qh4 20.Nd5 Bxd5 21.exd5 Rxe1 




22.Rxe1

After the game, Houdini suggested that I should have started looking for a draw here with 22.Qa8+ Kd7 23.Qc6+ Kd8 24.Rxe1 Ne7 25.Qa8+ Nc8 26.g3 Qg4 27.Kg2 Re8 28.Rxe8+ Kxe8 29.b4 Qe2+ 30.Kh3 Qh5+ 31.Kg2 Qe2+ 32.Kh3 Qh5+


22...Kb7 23.g3 Qg4 24.Qc3




Overlooking danger: 24.d4 was necessary.

24...Nxf4


Even stronger: 24...Nh4.


25.Bxf4 Rxf4 26.b4


One last gasp. Where's a good swindle when you need one?


26...Nd7


That should do it. Of course, 26...Rxb4 keeps Black on top.


27.Qc6+



Now White can answer  27...Ka7 with 28.Qxc7+ Ka6 29.b5+ Ka5 30.Qc3+ Ka4 31.Qb3+ Ka5 32.c4 Rxc4 33.dxc4 Qd4+ 34.Re3 and advantage - if he sees it.


27...Kc8 28.Qa8+


Yipes! Instead, my opponent walks into a mate-in-one (28.Re8#) - and I miss it.


We both deserve to lose. I deserved it more.


28...Nb8 29.Re8+ Kd7 30.Re1 


Alas, capturing Black's Knight allows him to checkmate me.


30...Rf8 31.Qa4+ Kc8 32.c4 Qd4+ 33.Kh1 Qf2 34.Re8+ Rxe8 35.Qxe8+ Kb7 36.h4 Qxg3 37.Qe4 Qf2 38.Qg2 Qxg2+ 39.Kxg2 Nd7 


The endgame is fairly won for Black.


40.d4 b5 41.c5 Nf6 42.cxd6 cxd6 43.Kf3 Nxd5 44.a3 Nc3 45.Kf4 Nb1 46.Kf5 Nxa3 47.Ke6 Kc7 48.Kf7 g6 49.Kg7 Nc2 50.Kxh7 Nxb4 51.Kxg6 Nd5 


White's King has gotten his exercise, but it doesn't save the game.


52.Kf5 Nc3 53.h5 b4 54.h6 b3 55.h7 b2 56.h8Q b1Q+ 57.Ke6 Qe4+ 58.Kf7 Qf5+ 59.Ke7 Nd5+ White resigned

Jerome Gambit to the Rescue!


With one game left in the Italian Game Tournament at Chess.com (see "Swan Song") I relied on my trusty Jerome Gambit, and it did not fail me. Thus, I am likely to finish 3rd (out of 19 players) with a score of 13-6-5 (5-3-0 with the Jerome Gambit).


perrypawnpusher - MarkHundleby1
Italian Game Tournament, Chess.com, 2013

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




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6


I was comfortable entering this line, as I have played it over 100 times, scoring 81%.

7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6




I have been here, too, in 44 games, also scoring 81%


10.O-O Qe7 11.Nc3 b6 12.f4 Bb7 





13.f5 Ne5 14.d4 Ned7


A bit of an improvement over 14... Neg4, from perrypawnpusher - Navarrra, blitz, FICS, 2011 (1-0, 24) - which I still have to post here, one of these days.

15. Re1 Kd8 16. e5 dxe5 17. dxe5 Nd5



Bill Wall pointed out after the game that this was an error - one both my opponent and I overlooked. He suggested, instead, 17... Ng4!?

18.Qg3


Instead, 18.Nxd5 Bxd5 19.Rd1, followed by e6, as pointed out by Bill, would give White the advantage.


18...h6 19.Be3 


Again: 19.Nxd5 Bxd5 20.Rd1


19...Nxe3 20.Rxe3 Qg5 21.Qxg5+ 


Bill preferred keeping the Queens on the board with 21.Qf2


21... hxg5 22.Rd1 Ke8 




I remember analyzing this position, and then seeing my opponent's move, thinking I didn't think he could play that move...  After 22...Kc8, instead, I agree with Bill that Black is a little bit cramped but still ok.


23.Nb5


I remember thinking that after having played 19.Be3 and 21.Qxg5+, that the text would look like another "just making moves" kind of piece-shifting. I could imagine my opponent thinking: Now we just exchange c-pawns with 23...Ke7 24.Nxc7 25.Rac8 Nb5 26.Rxc2 and then Black has deadly pressure on g2...


23...Ke7 


Better 23...Rc8 24.Nxa7 Rd8 25.Nb5 Nc5 26.Nxc7+ Ke7 with an even game. 


24.Nxc7 Rac8  


25.f6+ 


The "Jerome pawns," instead, mix things up. They blow up the center, and suddenly Black's King is in great danger.


25...gxf6 26.exf6+ Kf8 27.Rxd7 Black 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

It all adds up


I have mentioned elsewhere GM Bronstein's lighthearted comment that in chess, three small errors tend to add up to one big error. In the following game, Black suffers a loss more because he loses his way against the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxv7+) than because of any great blunder.


perrypawnpusher - Unimat
blitz, FICS, 2011

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


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6


7.Qd5+ Ke8 8.Qxc5 d6 9.Qe3 Nf6


10.0-0 Qe7 11.Nc3 Be6

Black has any number of alternatives, including 11...b6 as in perrypawnpusher - Navarrra, blitz, FICS, 2011, (1-0, 24); 11...Rf8 as in mrjoker - rex3, Internet Chess Club 2009 (1-0, 50),  perrypawnpusher - MRBarupal, blitz, FICS, 2010 (0-1, 31), perrypawnpusher - parlance, blitz, FICS, 2011 (1-0, 20) and perrypawnpusher - chingching, blitz, FICS, 2011 (½-½, 36); 11...Ne5 as in perrypawnpusher - mikelars, blitz, FICS, 2011 (1-0,50); and 11...Kd7 as in perrypawnpusher - parlance, blitz, FICS, 2011 (1-0, 22).

The text encourages White to play f2-f4-f5.

12.f4 Bd7

Losing a tempo.

The alternative, 12...Bc4, was seen in QuadCoreBR - Alecs, blitz, FICS, 2008 (1-0, 27) and perrypawnpusher - ZhekaR, blitz, FICS, 2011 (0-1, 36).

Too risky is 12...Kd7 as in perrypawnpusher - Solaar, blitz, FICS, 2011 (1-0, 33).

13.f5 Ne5 14.d4 Nc4 15.Qd3 Nb6


The "Jerome pawns" are rolling and White has the advantage.

16.Bg5 h6 17.Bh4 Qf7

Moving out of the pin on the Knight, but it is interesting to see what Houdini recommended after the game: 17...Rd8 18.e5 dxe5 19.dxe5 Bc6 20.exf6 gxf6 21.Qg3 Kd7 22.Rae1 Qc5+ 23.Qf2 Qxf2+ 24.Rxf2 Rde8 25.Rfe2 Rhf8 26.Rd1+ Kc8 27.Rxe8+ Rxe8 28.Bxf6 Nc4 29.Nd5 Bxd5 30.Rxd5 Ne3 31.Re5 Rxe5 32.Bxe5 Nxf5.





analysis diagram








White's attack has been neutralized, but his extra pawn and Bishop vs Knight should win in the end.

18.e5 dxe5 19.dxe5


19...Nfd5

This raises the level of danger, but Houdini's suggestion 19...Qc4 20.Qxc4 Nxc4 21.exf6 will lead to a two-pawn advantage for White, any way.

The tactics all go White's way now.

20.e6 Qh5 21.exd7+ Kxd7 22.Nxd5 Nxd5 23.Qxd5+ Kc8


24.g3

The computer later pointed out that the Bishop was untouchable: 24.Rad1 Qxh4 25.f6 leads to mate.

24...Rd8 25.Qxd8 checkmate

Don't Blame the Jerome Gambit (Part 2)


Yesterday's game featured White reaching a fine Jerome Gambit position out of the opening, only to miss all of the attacking splendor that he had available. Sad.

In today's game, Black understimates the danger that he faces and quickly goes from two pieces up to two pawns down. Instead of my usual, conservative, "consolidate at all costs" approach, I decided to attack violently.

And it would have worked, too, if I hadn't hung my Queen.

Again: don't blame the Jerome Gambit for this "0-1".

perrypawnpusher - chingching
blitz, FICS, 2011

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


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf6


A rare, usually careless (see the "Halo Effect" theme) response that takes Black quickly from a won game to nearly lost one. It is not an "instant victory", but it should be close. 

7.Qf5+ Ke7 8.Qxe5+ Kf7 9.Qd5+ Ke8 10.Qxc5 d6 11.Qe3 Nf6


The Queen checks were covered in the notes to my recent games against badhorsey (1-0, 30) and navarrra (1-0, 26). Her Majesty has now returned home safely, two pawns to the better.

12.Nc3 Kf7 13.0-0 Re8 14.d3 c6 15.f4 Ng4


Completing castling-by-hand with 15...Kg8 or striking the center with 15...d5 were better ideas than the off-task, but irresistible, strike at the White Queen.

16.Qg3 Kg8 17.Bd2 d5 18.Rae1 Qb6+


This move caught me by surprise. It is actually a time-waster: compare White's Bishop and Rooks to Black's Bishop and Rooks and ask should Black be taking his Queen away from the action to win a pawn or two?

The similarity to the wandering enemy Queens in my games against irak (1-0, 33) and jgknight (1/2-1/2, 49) encouraged me.

19.Kh1 Qxb2 20.f5 Qxc2


21.Qxg4

Unnecessarily acrificing the Bishop at d2 because I believed that I had a "killer" followup move.

After the game, Houdini suggested the prudent 21.Nb1, instead, as White actually has time to protect his Queenside minor pieces because the Black Knight on g4 isn't going anywhere: after 21...Nf6 White would play 22.e5 and Black's "best" would be to hang his horsie out to dry again with 22...Nh5 23.Qf3.

Houdini's suggestion of 21.Nb1 Rf8 22.Rc1 allows Black to complete his Queenside meal with 22...Qxa2, but after 23.Qxg4 White will go a piece up and soon position his Bishop on the a1-h8 diagonal and advance his "Jerome pawns" with a winning attack on the King.

21...Qxd2

Now, the rather pathetic 22.Ne2 would preserve whatever was left of White's initiative, giving him a small edge at the very best, due to Black's delayed development.

22.f6

Well, at least I could say that the odds were with me: Black has 41 possible responses, and 40 of them lose, almost all of them very quickly.

22...Bxg4

Of course, that one remaining move wins my Queen...

I played on a bit longer and recovered some material, but there was no way that I was going to survive being down a Rook for a Queen.

23.f7+ Kf8 24.fxe8Q+ Kxe8 25.exd5+ Kd7 26.dxc6+ Kxc6 27.Ne4 Qxd3 28.Rc1+ Kb6 29.Rb1+ Ka5 30.Nf2 Qc4 31.Rfc1 Qd4 32.Nxg4 Qxg4 33.Rc3 b5 34.Ra3+ Kb6 35.Rab3 a6 36.Rd3 Rc8 White resigned


My opponent finished up nicely and deserved his comeback win.

Again, don't blame my loss on the Jerome Gambit!

Powerful Like a Storm

When the creative and indomitable Danish Grandmaster Bent Larsen wrote "A Personal Approach to the Openings" for the wonderful How To Open A Chess Game, he began the chapter by recalling that when he was 9 he found a chess book that inspired him, even if, he admitted, the text was 20 years old and the chess ideas of the author at least three times that aged. Larsen remembered an inspiring quote  

The Jerome Gambit is powerful like a storm; nobody can tame it. Nothing shows more clearly the lack of greatness in the chess professions of today than the fact that none of them have the courage to play the Jerome Gambit...
Oh, no, wait a minute, I got that wrong: the author was writing about the King's Gambit, not the Jerome...

perrypawnpusher  - badhorsey
blitz, FICS, 2011

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


4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf6

Shades of my game against Navarrra (see "Over").

7.Qf5+ Ke7 8.Qxe5+ Kf8

Staying out of further trouble.

9.Qxc5+ d6 10.Qe3 Nf6


White is two pawns up, with the safer King.

11.0-0 Qe7 12.Nc3 c5 13.d3 Kf7 14.b3

My opponent was using up a lot of thinking time on each move, so I decided to develop conservatively (using a formation that I borrowed from the b3 Sicilian) – to stay away from something bright, sharp, brilliant and wrong.

14...Rf8 15.Bb2 Kg8 16.Rae1 b6 17.f4 Ng4



Black has castled-by-hand, and with the exception of his Bishop (which I had expected to go to b7) his developement has progressed as well. The text move shows the irresistible temptation (which should, nonetheless, be resisted) to harass the Queen.

18.Qg3 Bd7 19.Nd5

From this point on, White's game becomes scarier and scarier (for Black).

19...Qd8 20.h3 Nf6 21.Nxf6+ Rxf6 22.Bxf6 Qxf6 23.e5 Qe6 24.f5 Qd5 25.e6 Bc6 26.f6


Those "Jerome pawns"!

26...g6 27.f7+ Kf8 28.e7+ Kg7 29.f8Q+ Rxf8 30.exf8Q checkmate
