Strike While The Iron Is Hot


My most recent two Jerome Gambit games seem to illustrate the two classes of battle that I get enmeshed in. 

Sometimes my opponent plays well, and there comes a time when I need to act decisively - or lose the game.

Sometimes the game has a multitude of complex alternatives - and the player who misses out on the last one drops the point.

First, and example of the first.

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Nc3 Bc5 5.Bxf7+


The Italian Four Knights Jerome Gambit.

5...Kxf7 6.Nxe5+ Nxe5 7.d4 Bxd4 8.Qxd4 d6 9.0-0 h6


Transposing to the Semi-Italian Four Knights Jerome Gambit.

10.f4 Nc6 11.Qd3 Re8 

I have reached this position 15 times before and each time played 12.Bd2, scoring 70%, which is about my result for the IFKJG, but not as good as my result in the S-IFKJG.

For some reason, I decided to try something different.

12.b3 Kg8 13.Bb2 Bg4 14.h3 Bh5 15.Rae1 Bf7 16.Nd5 Nxd5 17.exd5 Nb4 

With only a pawn for my sacrificed piece, I needed some "cooperation" from my opponent, and here it is. The iron is hot.

If you had told me that Houdini now recommends 18.Qg3 Bg6 19.Qxg6 with advantage to White, I would not have argued (although I might have chuckled). I had looked at 18.Qg3, and was not afraid of Black returning a piece - I expected that instead he would play the logical follow-up to his Bishop maneuver, 18...g6.

In my calculations I missed the fact that 19.Qc3 would then be crushing - actually forcing a checkmate in no more than 8 moves!

18.Qc3 Qf6 

The difference: had I first forced ...g7-g6, this would not have been playable.

19.Qxf6 gxf6 20.a3 Nxd5 21.c4 Ne3 22.Rf3 Nf5 23.Rxe8+ Rxe8 24.Bxf6 Re3 25.Kf2 Rxf3+ 26.Kxf3 d5 



White's situation is not hopeless - my opponent was becoming short on time. A slim hope.

27.g4

Probably better was 27.c5


27...Nd6 28.c5 Nb5 29.a4 Na3 30.g5 hxg5 31.fxg5 Nc2 32.Ke2 d4 33.Kd3 Bxb3 34.Bxd4 Nxd4 35.Kxd4 Bxa4



At this point my only hope was the clock, but it was not to be. My opponent moved quickly on his 2-second increment... The rest of the game would only be relevant if I had won on time. Maybe not even then.

36.h4 Be8 37.Kc4 a6 38.Kb4 Kg7 39.h5 Bxh5 40.c6 b6 41.Kc4 Bf3 42.Kb4 Bxc6 43.Kc4 Kg6 44.Kb4 Kxg5 45.Kc4 Kf5 46.Kb4 Ke5 47.Kc4 a5 48.Kb3 b5 49.Kc3 Bd5 50.Kb2 b4 51.Kb1 a4 52.Kb2 a3+ 53.Kb1 b3 54.Ka1 b2+ 55.Kb1 Be4+ 56.Ka2 b1Q+ 57.Kxa3 Bd5 58.Ka4 c6 59.Ka5 Qb5 checkmate

Stepping Out of the Ring (temporarily)


I'm always up for a Jerome Gambit, if my opponent allows it.

Well - almost always. Sometimes my patience falters.

But that doesn't mean that I can't still play cheesy chess.

blitz, FICS, 2013

1.e4 e5 2.Nf3 Nc6 3.Bc4 h6


Side-stepping the Jerome Gambit for the Semi-Italian Opening.

4.0-0

Hoping for 4...Bc5 and a chance at the Semi-Italian Jerome Gambit.

4...Nf6 5.Nc3

Okay. Looking for 5...Bc5 and the ability to play the Semi-Italian Four Knights Jerome Gambit.

5...a6 

My opponent holds off on his ...Bc5. I've fussed about this before, in "Are We There Yet?"

6.d4

Giving up on the Jerome Gambit.

Previously I prevaricated with 6.a3 and then my opponents allowed me my wish by playing ...Bc5: perrypawnpusher - cinamon, blitz, FICS, 2010 (1-0, 28); and perrypawnpusher - Olito, blitz, FICS, 2011 (0-1, 35).

I also "passed" with 6.d3, getting a chance to sacrifice my Bishop as well, in perrypawnpusher - tschup, blitz, FICS, 2010 (0-1, 18)

Bill Wall played 6.a4 and scored with 6...Bd6 7.Bxf7+ Kxf7 8.Qe2 Re8 9.Qc4+ Kf8 10.Nh4 Ne7 11.d3 b6 12.f4 a5 13.fxe5 Bxe5 14.d4 d5 15.exd5 Bd6 16.Bxh6 gxh6 17.Rxf6+ Kg7 18.Raf1 Ba6 19.Nb5 Be5 20.dxe5 Qxd5 21.Qg4+ Kh7 22.Rf7+ Kh8 23.Qg7 checkmate, Wall,B - Kamyar,K, Chess.com, 2011.

6...exd4 7.Nxd4 Bc5 

8.Be3

I suppose that I could have still tried 8.Bxf7+, (although there are no examples in The Database) but I wanted to play this not-very-deep "trappy" move, as it was easy to guess my opponent's routine response.

8...0-0

Routine, but trouble.

9.Nxc6 bxc6 10.Bxc5

My opponent resigned a few moves later.

Here are a couple of similar examples, by long-time Jerome Gambit Gemeinde member PlatinumKnight.

Riddle Me This, Fat Man


The following game can be looked at as a series of riddles posed to the "hero" (that would be me, I guess) on his way to an unexpected victory - isn't that the only kind of win for White that comes in the Jerome Gambit?

Sadly (for him), my opponent could not solve his own final riddle...


I have given game references for early in the play, to see how to deal with riddle #1 (7...Qe7, the Jerome Defense to the Jerome Gambit, by the way) and riddle #2 (9...Nh6), but after that you are largely on your own - as I was.


perrypawnpusher - Kleini

blitz, FICS, 2013

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




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Kf8 7.Qxe5 Qe7 8.Qf4+




I would rather not exchange Queens at this point.


8...Qf6 


The alternative 8...Nf6 is as old as two Jaeger,D - Jerome,A correspondence games from 1880, wins for Black in 14 and 40 moves.


At a faster time control, I have been more successful: perrypawnpusher - ERICOLSON, blitz, FICS, 2007 (1-0, 33);  

perrypawnpusher - frencheng, 10 5 blitz, FICS, 2010 (½-½ , 31); perrypawnpusher - jonathankochems, blitz, FICS, 2010 (1-0, 39); and perrypawnpusher - Chesssafety, Chess.com, 2012 (1-0, 25). 

9.Qg3 


Not 9.Qxc7? Qxf2+ 10.Kd1 d6


9...Nh6 


An interesting novelty of questionable value. 


Previously seen have been 9...d6 in Wall,B - Guest340293, Playchess.com, 2012 (1-0, 41), perrypawnpusher - JoseSoza, Chess.com, 2012 (0-1, 37), and Wall,B - Josti, Playchess.com, 2013 (1-0, 26); and 9...Bd6 in perrypawnpusher - molerat, blitz, FICS, 2010 (1-0, 23). 


10.Nc3 d6 11.Nd5 Qf7 12.0-0 c6 




13.Nc3 


Houdini 3's solution to the riddle of this position is 13.d4!? The silicon superstar sees White drawing by repetition after 13...cxd5 14.dxc5 dxe4 (14...dxc5 15.Bxh6 gxh6 16.Qd6+ Kg7 17.Qg3+ etc.) 15.Bxh6 gxh6 16.Qxd6+ (16.f3!? is an interesting attempt for more, e.g. 16...e3 17.Rfe1 Bf5 18.Rxe3 Qf6 19.Qf4 Rg8 20.cxd6 ) Kg7 17.Qg3+ Qg6 18.Qc7+ Qf7 19.Qg3+, etc.


It's all  a bit over my head. Okay, more than "a bit". 


13...Be6 14.d3


Again, 14.d4!? seems to be the key to the position, 14...Bb4 15.a3 Bxc3 16.Qxd6+ Qe7 17.Qf4+ Kg8 18.bxc3 and Black's edge is minimal.


14...Qg6 


15.Qxg6


By now the alternative (according to Houdini 3) should be predictable: 15.d4!? Bb4 16.a3 Bxc3 17.Qxd6+ Kg8 18.bxc3 Nf7 with a small edge to Black.


15...hxg6 


White has two pawns for his sacrificed piece. 


The Knight escapade that I started with my next move was a bad idea, and led to a lost position. I should have moved the piece to the Kingside with 15...Ne2.


16.Na4 Bd4 17.c3 Bf6 18.b3 b5 19.Nb2 Bxc3




20.Rb1 Ke7 21.Nd1 Bd4 22.Ne3 Ng4 23.h3 Nxe3 24.fxe3 Be5 25.d4 Bg3 26.Rf3 Bh4 


Black's two Bishops are scary. He just has to be careful, and he can bring home the point.


Of course, that was true 20 moves ago, too.


27.Ba3 Rhf8 28.Rbf1 a5 




I don't blame you if you didn't shout "He should have exchanged Rooks before playing that move!" I didn't realize that it was that critical, either.


29.Bxd6+


Exchanging Rooks, too, here is supposed to be stronger, according to Houdini 3. I was just glad to have a shot at bringing the game closer to equal.


29...Ke8 


Wow. Surprised by my move, my opponent stumbles hard. That's blitz for you.


Instead, after 29...Kxd6 30.Rxf8 Ra7!? Houdini 3 believes Black's two Bishops balance out White's Rook and two extra pawns. Play would remain tricky, but if White can collect and/or exchange some pawns, he should be able to split the point.


30.Rxf8+ Black resigned

Endgames Revisited




After "Jeromezzzzzzzzzz... Gambit" I decided to review earlier blog posts and pull together a number of Jerome Gambit endgames, for those who want to practice (or laugh).

The endgame? "It's Just Really That Important". Even if you're convinced that "Nothing Happened".

There's a fun contest that contains both the "Bishops of Opposite Colors" and the "Wrong Bishop + Rook Pawn": "All's Not Well That Ends Not Well."

There are a couple of games aptly titled "With The Pawns, Against the Bishop" (although the second game is titled "Really? Really.")

There's a "down the exchange but up the pawns" game in "More Than Seen At First Glance (Part 1)" and a regular Opposite Colored Bishops contest in "More Than Seen At First Glance (Part 2)".

I'll finish with an escape into an Opposite Colored Bishops endgame in "Win, Lose, Draw".

Opening Encyclopedia 2013 (followup)


My hopes concerning the recent release of Opening Encyclopedia 2013 were raised by Albert Silver's review at ChessBase.com, where he wrote

you will also find a wealth of material on offbeat lines... and every oddball line that may tickle your fancy. Someone played a gambit or line at your club or online and you had no idea what to do? Rest assured, there is an article here to enlighten you.

Even coverage of the Jerome Gambit?

Today's email brings the answer
Dear Rick,

Do not even get to your pocket! ChessBase's Opening Encyclopaedia 2013 has no entry on the Jerome GambitI have reviewed and it does not have anything on our gambitA hug!

Monumental Effort


The following game is a titanic struggle and monumental effort by both parties. White's early Queen moves prompt his opponent to try to punish them. Before a couple of dozen moves are past, an unbalanced (but balanced) endgame presents itself, and the game is not yet half over.

Bill Wall's endgame play is worth studying by any Jerome Gambiteer who suspects that he might not win all his games by first round knockout.


Wall,B (2000) - Seven11
Chess.com, 2008

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




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ng6 



7.Qxc5 d6 8.Qd5+


A different way to "put the question to the Bishop." Does Black want to play 8...Be6 and allow 9.Qxb7, ?

In three previous games, Bill's opponents have answered no, no, and yes with 8...Ke7 (Wall - Guest 4395, Microsoft Internet Gaming Zone, 2001 [1-0, 18]), 8...Kf8 (Wall - Chung, Chess.com, 2010 [1-0, 25]) and 8...Be6 (Wall - CheckMe, Chess.com, 2010 [1-0, 23]). - Rick


8...Ke8


9.d3 c6 10.Qb3 Nf6 11.0-0 Qe7 12.Nc3 Be6 13.Qa4 b5 14.Qa6 Qc7 15.Be3 Ke7 16.f4 Bc8 17.Qa3 c5 




Black's play against White's Queen has been quite aggressive (13...b5!?, 15...Ke7!?, 16...Bc8!?) and although White may "objectively" have a whisper of an advantage in the diagrammed position (at least if it is Houdini 3 doing the whispering) the game is tense and complicated.


18.Nxb5


The natural move that White wants to make, and that Black wants him to make.


The un-natural (read: computer) move is 18.e5!? when 18...b4 19.exf6+ Kf7 20.Qb3+ Be6 21.Nd5 Qb7 22.c4 Bxd5 23.cxd5 gxf6 would be a mess, but, perhaps, a White-tinged mess.


18...Qc6 19.Nxa7 Qb7 20.Nxc8+ Rhxc8 




White now has four pawns for his sacrificed piece, but Black's pressure on the Queenside is substantial.


Black's goal is to recover some material. Whit'es goal is to move into an endgame where he has the prospects of converting a pawn.


21.Qc3 Qb4 22.f5 Qxc3 23.bxc3 Ne5 




24.Bf4 Kd7 25.Bxe5 dxe5 26.a4 Ra5 27.Rfb1 Rc7 28.Rb5 Rca7




Houdini 3 says that 28...Rxb5 29.axb5 c4 30.Ra3 Kd6 31.Ra6+ Kc5 32.Re6 cxd3 33.cxd3 Kxb5 34.Rxe5+ Ka4 would also be equal, 

analysis diagram






but wouldn't you rather have White?



29.c4 


Bill suggests 29.Rxa5 Rxa5 30.h3 as an alternative.


29...Kc6


Likewise, Bill points out that 29...Rxa4 30.Rxa4 Rxa4 31.Rb7+ Ke8 32.Rxg7 Ra1+ 33.Kf2 Rc1 34.Kf3 Rxc2 would get rid of the annoying a-pawn and keep Black's remaining Rook active.


30.Rxa5 Rxa5 31.Kf2 Nh5?! 




Getting active on the Kingside, and thus keeping White's King there. Bill prefers that Black shift his King over that way.


32.g4 Nf6 33.g5 Nh5


Not 33...Ng4+? 34.Kf3 Nxh2+ 35.Kg3 and the greedy Knight is trapped; while if 33...Nd7 then 34.h4


34.Ke3 Nf4 


White still has all of his pawns.


35.f6?!


Perhaps a bit precipitate. Bill prefers 35.h4 h5 36.gxh6 gxh6 37.c3.


 35...g6? 


Better: 35...gxf6 36.gxf6 Kd6 and still a game in balance.


36.c3?!


Better, too, to move the King to prepare to advance his h-pawn, 36.Kf3 Ne6 37.Kg4.


36...Nh3 


Or 36...Ng2+ 37.Kf3 Nf4 38.d4 cxd4 39.cxd4 Nh3 40.dxe5 Nxg5+ 41.Kf4 


37.d4


There is not much more in 37.Rf1 Ra8 38.a5 Nxg5 39.a6.


37...exd4+ 38.cxd4 cxd4+ 39.Kxd4 Nxg5 




White now has four (!) passed pawns, and the easier game to play, but, to be fair to his opponent, the game is still even.


40.h4 Ne6+


There is no more in 40...Nf3+ 41.Kc3 Nxh4 42.f7 Ra8 43.a5 g5 44.a6 Ng6 45.a7 g4 46.Kc4 g3 47.Ke3 g2 48.Kf2 Ne5.

analysis diagram









41.Kc3 Nc5 


Bill points out that shifting defenders doesn't accomplish much: 41...Re5 42.a5 Rxe4 43.a6 Nc7 44.Rf1.


42.f7


Nothing more is available from 42.e5 Nd7 43.f7 Rxe5


42...Ra8 43.Rf1


Or 43.e5 Kd7 44.Rf1 Rf8




43...Nxe4+??


Black gobbles a poison pawn (with check). Who can blame him? He needed the patience to find 43...Rf8 44.e5 Kd7 45.Kd4 Ne6+ 46.Kd5 Ke7 47.c5 Rd8+ 48.Kc4 Rc8 49.Kb4 Kf8, when White's energy exhausts itself, e.g. 50.a5 Nxc5 51.Kb5 Ne6 52.Rd1 Kxf7 53.Rd7+ Kg8 54.Rd6 Re8 55.Kb6 Nd8 56.a6 Nf7 57.Rd5 Nxe5 58.a7 Re6+ and Black's checks will keep White's last dangerous pawn from Queening. Whew!


44.Kd4 Rf8


Bill gives this move a "?", but after the alternative 44...Ng3 45.f8Q Rxf8 46.Rxf8 Nf5+ 47.Kc3 Nxh4 48.a5 White is more than just the exchange ahead. His a-pawn will cost Black his Knight, and his Rook can feast on the remaining two Black pawns long before they become threats to Queen.


45.Kxe4 Kc5 


46.a5 Kxc4 47.a6 Kb5 48.a7 Kb6 49.Ra1 Ra8 50.Rb1+ Kc6 51.Rb8 Black resigned

Alonzo Wheeler Jerome's Dream


If Alonzo Wheeler Jerome, the creator of the Jerome Gambit, ever dreamed of an exciting game, it might very well have looked like the following one.

Wall,B - Guest1157782

playchess.com, 2013

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




4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.f4 Ng6



The kind of move - withdrawing a piece from attack - that someone unfamiliar with the Jerome Gambit might make quickly. (Best was 7...Qf6).

My guess is that at this point Bill got out his psychic micrometer, measured the apparent depth of his opponent's experience with (or understanding of) the opening, and chose a line of play that was most efficacious against an unschooled or uneasy opponent. 

8.f5+

Also seen:


8.Qf5+ as in Idealist - pvm, FICS, 2003 (1-0, 42), Petasluk - jackla, FICS, 2008 (1-0, 31), and Petasluk - popasile, FICS 2011 (0-1, 35);


8.Qxc5 as in Permanence - Pianisimo, FICS, 2008 (1-0, 17) and Permanence - jgknight, FICS, 2008 (0-1,38); and


8.Qd5+ as in Siggus - svetma, FICS, 2007 (1-0, 36).


All of these games can be found in The Database.


8...Kd6

Or 8...Ke5, which led to a quick win for White in Superpippo - HarryPaul, FICS 2001 (1-0, 15).

9.fxg6 Kc6

Instead, Black had to fight back with 9...Nf6.

10.Qd5+ Kb6 11.Qb3+ Kc6

Surprisingly enough, Black's King can escape with 11...Ka6 - if he keeps his wits about him. Sure, White can then win back a piece with 12.Qc4+ b5 13.Qxc5, but after the counter-attack 13...Qh4+!? Black can get his Queen over to protect His Majesty, e.g. 14.Kf1 Qxe4 (Black could also try 14...Ne7 with the idea of 15...Rf8+)15.d3 Qc6 when 16.Qxc6 dxc6 17.gxh7 gives White a small advantage, according to Houdini 3.

12.Nc3 hxg6 

Now White finishes things off.


13.Qd5+ Kb6 14.Na4+ Ka5 15.b4+ Kxa4 16.Qb3+ Kb5 17.a4+ Kc6 18.Qd5+ Kb6 19.Qxc5+ Ka6 20.Qa5 checkmate
