Jerome Gambit - Over the Board??


In a comment to the previous post on this blog, Quckturtle asked if I played the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) in over-the-board games.

I responded in the negative, mostly because I rarely play face-to-face games these days; instead, I play blitz and turn-based games on the internet.

Indeed, Eric Schiller, in his 2002 Gambit Chess Openings, referred to the Jerome Gambit as a "cyberspace gambit".

Yet, I wonder along with Quickturtle: who plays the Jerome Gambit in over-the-board play these days?

I have known for years that Jerome Gambit Gemeinde member Pete Banks ("blackburne") from Great Britain used to play it regularly - but, who else?

If you know someone, or if you play the Jerome otb yourself, please drop me a quick note (richardfkennedy@hotmail.com) or add a comment to this post, and let us know.

Tossed Back And Forth


Here is the second kind of Jerome Gambit game that I encounter, where my opponent and I toss the game back and forth, and there are plenty of chances for me to take the advantage and run.

Sometimes, like in the following game, I do so.


perrypawnpusher  - charlyeliot

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 d6 9.Qe3 Nf6 


A familiar position - I've been here over 40 times, scoring over 80%.


10.0-0 Bd7 11.f4


Standard pawn play for me, but perhaps 11.d4 was a bit better.


11...Bb5


Or 11...Qe7 as in perrypawnpusher - peroneal, blitz, FICS, 2009 (½-½, 56).


12.d3 Ng4 13.Qg3 Nf6 


The Knight returns home. From a different perspective, 13...Qh4, looking to exchange Queens, was playable. (Curiously, an almost identical position after 13...Qh4 occurred in Wall, B. - Guest3312852, Playchess.com, 2012 [1-0, 26], only Black's Bishop was on c4 and White's Knight was on c3.)


14.Nc3 Qd7


I occasionally use Houdini 3 to help me understand what is going on. Using "blunder check" set at 5 minutes per move, the program boiled the game down to the basics: 14...Bc6 15.f5 Nf8 16.d4 h5 17.Re1 Kf7 18.Bg5 Kg8 19.e5 dxe5 20.dxe5 h4 21.Qf4 Nd5 22.Qd2 Qd7 23.e6 Qd6 24.Nxd5 Qxd5 25.Qxd5 Bxd5 26.e7 Bc6 27.exf8Q+ Rxf8 28.Re5 Rh5 29.f6 gxf6 30.Bxf6 where White has a small, but perhaps not decisive edge.


Who knew?


15.f5


This move is okay, but I missed 15.e5 dxe5 16.fxe5 Nd5 17.e6!? which sets up the tactical shot 17...Qc6 18.Nxd5 Qxd5 19.c4 winning a piece.


15...Ne5 16.d4


This exchange sacrifice is not good.


16...Nh5


Trying to complicate things, when 16...Bxf1 17.dxe5 dxe5 18.Qxe5+ Kf7 19.Kxf1 Rhe8 20.Qf4 Qe7 would leave Black with an edge. 


17.Qg5 Bxf1 18.Qxh5+


This allows Black's other Knight to escape directly, whereas Houdini 3's choice was: 18.dxe5 g6 19.e6 Qg7 20.Kxf1 c6 21.Kg1 h6 22.Qg4 Nf6 23.Qf3 Rg8 24.h3 Rd8 25.Ne2 gxf5 26.exf5 Ke7 27.g4 Nd5 28.c4 Nb4 with advantage to White. 


18...Nf7 19.Kxf1 Qc6 


The smoke is clearing, and White has two pawns for the exchange.


20.Be3 Qa6+ 21.Kg1 Qc6 22.e5 dxe5 23.dxe5 g6 24.fxg6




Stronger was 24.Qh3 gxf5 25.Rf1.


24...Qxg6 25.Qxg6


Exchanging favors. Black should have captured on g6 with the pawn, and White had a much better choice in 25.Qe2!?


25...hxg6 26.Bd4 Rh6 27.Nd5 




There is still a fight going on. Black should now protect his c-pawn with his Rook, as his choice of moves allows another tactical shot (which I missed).


27...Kd7 28.Rd1 


Instead, 28.e6+!? wins material.


28...Kc6 29.Nb4+ Kb5 30.Nd3 a6 




More slipping and sliding.


31.Nf2


Missing a chance to show some cooperation among my pieces, winning material: 31.a4+ Kxa4 (31...Kc6 32.e6 Kd5 33.Nf4+ Ke4 34.exf7 Kxf4 35.Bc3 Rh7 36.Rf1+ Ke4 37.f8Q Rxf8 38.Rxf8 ) 32.b3+ Kb5 33.c4+ Kc6 34.e6 Nd8 35.Nb4+ Kd6 36.Bg7+ Kxe6 37.Bxh6.


31...Rd8 32.h3 


And the game is about even.


32...Kc4 33.Bc3 Re8 


Exchanging Rooks was the right idea. Now Black gives back the exchange, and White starts pushing things.


34.Ng4 Rh5 35.Nf6 Rd8 36.Rxd8 Nxd8 37.Nxh5 gxh5




38.Kf2 Ne6 39.Kg3 b5 40.Bd2 Kd5 41.Bf4 Nxf4 42.Kxf4 c5 43.g4 hxg4 44.hxg4 c4 45.g5 b4 46.g6 c3 47.b3 Ke6 48.g7 Kf7 49.Kf5 Kxg7 


50.Ke6 Kf8 51.Kd7 a5 52.e6 Kg7 53.e7 Kf7 54.e8Q+ Kg7 55.Ke7 Kh7 56.Qf8 Kg6 57.Qf6+ Kh7 58.Qg5 Kh8 59.Kf7 a4 60.Qh6 checkmate

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.

perrypawnpusher - BeeFiftyTwo
blitz, FICS, 2013

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.

perrypawnpusher  - kanidonara
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.

PlatinumKnight - strawks
blitz, FICS, 2005
1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.d4 exd4 5.Nxd4 Bc5 6.Be3 Nf6 7.Nxc6 bxc6 8.Bxc5 Nxe4 9.Bxf7+ Kxf7 10.Qf3+ Nf6 11.Bd4 Qe7+ 12.Kd1 Re8 13.Qb3+ d5 14.Nd2 Qe2+ 15.Kc1 Qe1+ 16.Rxe1 Rxe1 checkmate

PlatinumKnight - warehouse
blitz, FICS, 2005
1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 4.d4 exd4 5.Nxd4 Bc5 6.Be3 Nf6 7.Bxf7+ Kxf7 8.Nxc6 Bxe3 9.Nxd8+ Rxd8 10.0-0 Bg5 11.e5 Ng8 12.Qf3+ Ke6 13.Re1 c6 14.Nc3 b5 15.Ne4 Ne7 16.Nxg5+ hxg5 17.Qg4+ Kd5 18.Qxg5 g6 19.Rad1+ Kc5 20.e6+ Kb6 21.Qxe7 a5 22.Qxd8+ Kc5 23.e7 Bb7 24.Qxd7 Bc8 25.Qc7 Bf5 26.Re5+ Kb4 27.c3+ Ka4 28.Qxc6 Rb8 29.Rd4 checkmate

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!
