A Little Bit Of Discouragement, A Lot More Hope



Speaking of "Discouragement", I have to report that the second round of the Chess.com "Italian Game" tournament has started (two sections, one with 6 players, one with 7) and I have 4 games with the black pieces, 2 games with the white pieces - and no Jerome Gambits.

At least, not yet.

Not every one of my opponents in this round will defend with the Two Knights, will they??

I hope not.

In the meantime, some things to think about: "Jerome Gambit vs Two Knights Defense (Part 1), (Part 2), (Part 3) and (Part 4)".

Strike First!




Blitz games tend to be less strategic subtleties and more tactical tricks and turns. If you are planning on checkmating someone, it is best to be sure that he can't do the same to you, sooner.


Wall,B - Mydrik,M

PlayChess.com, 2015

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 


Black would like to take a detour into the Two Knights Defense. One way for White to hold out for a Jerome Gambit is now 4.Nc3, planning on meeting 4...Bc5 with 5.Bxf7+. Bill tries something else.


4.0-0


It is worth taking a minute to go back to the post "Jerome Gambit vs Two Knights Defense (Part 4)"


4...Bc5 5.Bxf7+ 


5...Kxf7


White has transposed to a "modern" variation of the Jerome Gambit, 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.0-0 Nf6. Bill has 11 examples in The Database, all wins. He decides to throw Nxe5+ in, anyhow.


6.Nxe5+ Nxe5 7.d4 


It is the pawns (White has two extra) vs the pieces (Black, temporarily, has two more), a typical Jerome Gambit imbalance. Bean counters look elsewhere.


7...Nxe4


Black probably would have done better with 7...Bxd4. 


8.Qh5+ Ng6 9.Qd5+ 


Bill stays true to his Jerome Gambit roots and "nudges" the enemy King to the back row. 


9...Kf8 10.dxc5 Nf6 11.Qd4 d5 12.Nc3




12...c6 13.Bg5 Kf7 14.Rae1 Rf8 15.Re2 Kg8 




Black has castled-by-hand, a practical decision in light of White's lead in development. 


16.Rfe1 Bf5 17.f3 Qd7 18.g4 Nxg4 




Black believes his return of the extra piece is exactly what he needs to press the attack. He is almost right here, but the correct move, leading to a complicated position, was 18...Ne4!.


Now White grabs the initiative.


19.fxg4 Bxg4 20.Re7 


This had to come as a surprise.


20...Nxe7 21.Rxe7 


Best for the defense now is 21...Rf7, when, after 22.Rxd7 Rxd7 White would have the advantage of a Queen and Knight against two Rooks and a pawn, but there would be plenty of play left in the game.


Instead, Black threatens mate - and receives it in turn.


21...Qf5 22.Qxg7 checkmate

Anybody want a couple of pieces?

Blue Question Mark

I guess not.

All of my games with White in first round of the ongoing Chess.com Italian Game tournament found opponents who did not want to allow the Jerome Gambit.

Four were Two Knights Defenses 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 that refused to turn into Italian Four Knights Jerome Gambits (4.Nc3 Bc5 5.Bxf7+) but stayed by the book with 4.Nc3 Nxe5 5.Nxe5 d5 6.Bd3 dxe4 7.Bxe4 Bd6.

The fifth game was a Semi-Italian game 1.e4 e5 2.Nf3 Nc6 3.Bc4 h6 that refused to go Jerome (with 4.0-0 Bc5 5.Bxf7+).

(The sixth game didn't happen, as the player lost on time in both games without a piece moved.)

Maybe next round.

I guess I will console myself with the knowledge that the readership of blog posts this month is likely to set a new record for jeromegambit.blogspot.com. Thanks for stopping by!

It's Not Over Until It's Over


I suppose that at least a few of the players defending against the Jerome Gambit figure that the game is over after the sacrificed Bishop is captured. Certainly, many believe that the game is over after the second piece is sacrificed and captured.


As more than a few discover, "it's not over until it's over."

soulman  - Pamswam
standard, FICS, 2014

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.0-0 Bc5 5.Bxf7+ Kxf7 



By transposition, via the Two Knights Defense, the game has reached a "modern" variation (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Not-Nxe5+) of the Jerome Gambit. White decides to "modernize" it after all.

6.Nxe5+ Nxe5 7.d4 Re8 8.dxe5 Rxe5 



Black has the better development and a piece for a pawn.

White has the pluck and the luck of the Jerome Gambiteer.

9.Kh1 d6 10.Nc3 Ng4 11.f4 Qh4 



Black's Queen swoops in to finish off the White King with checkmate. Things do not turn out as planned.

12.fxe5+ Kg8 13.Qd5+ Kh8 14.Rf8 checkmate



Now, it definitely is over.

Okay With The Delay


Lately, not a lot of opponents have answered 3...Bc5, which would give Bill Wall a chance to play the Jerome Gambit. In the following game he shows some patience, and it turns out that he is okay with the delay.

Wall,B - Marz
PlayChess.com, 31.08.2014

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 


The Two Knights Defense.


4.0-0


This reasonable move was looked at in "Jerome Gambit vs Two Knights Defense (Part 4)".


Bill has also played 4.Nc3 Bc5 5.Bxf7+ Kxf7 as in Wall,B - Samvazpr, Chess.com 2010 (0-1, 25); Wall,B - Roberts, Chess.com, 2010 (1-0, 17); Wall,B - DarkKnight, Cocoa Beach, FL 2012 (1-0, 23); Wall,B - Guest1459913, PlayChess.com, 2013 (1-0, 38);  Wall,B - Hamilton,E, FICS 2011 (1-0, 22); Wall,B - Guest1872464, PlayChess.com, 2014 (1-0, 30).


Of course, Philidor1792 has played 4.Bxf7+ here, any way, in 3-minute games.


4...Bc5


Or 4...Nxe4 5.Bxf7+ as in Wall, B - NTLZ, FICS, 2010 (0-1, 42).


Now there is a chance for a Delayed Jerome Gambit.


5.Bxf7+ Kxf7 6.Nxe5+ Nxe5 7.d4 Bd6 




This kind of retreat is seen by White in response to the "fork trick" in the Italian Four Knights Game. Here 7...d6 improves.


8.dxe5 Bxe5 9.f4 Nxe4


Looking for more trouble. Instead, 9...Bd6 10.e5 Bc5+ 11.Kh1 d5 12.exf6 gxf6 when White has an edge.


10.fxe5+ Nf6


Defense with 10...Ke8 is best, but after 11.Qg4 Qe7 12.Qxe4 White is a piece up.


11.exf6 g6 


Now the Jerome Gambiteer finishes with style.


12.Qd5+ Kf8 13.Bh6+ Ke8 14.f7+ Ke7 15.Qe5 checkmate

Not Quite The Same Thing


I am playing my last game in the first round of the current Italian Game tournament at chess.com. To date I have scored 5/7 -- including 2/3 with the Jerome Gambit -- and need only a draw (with White) to move on to the next round of play.

Alas, my opponent was not interested in allowing the Jerome Gambit, opting for the Two Knights Defense instead: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6

Still, I was able to maneuver things so that, after 4.d4 Nxe4 5.dxe5 d6 I was able to play the Jerome-ish 6.Bxf7+, when, after 6...Kxf7 7.Qd5+ Be6 8.Qxe4 I will be ahead material, and Black's King will be displaced. (The game continues.)



That is not quite the same thing as being in the Jerome Gambit after 8 moves (there I would be "objectively" lost) but it may be good enough to move me into the next round of play, where I can try my luck at playing a few more Jeromes.

Essence of Evans / Jerome / Halloween

In the following blitz game Philidor1792 shows his typical creativity, aggression and persistence in whipping up an interesting attack. Resistance is strong, however, and this time White does not win the day.

Philidor1792 - Guest292640
5 0, PlayChessbase.com, 2014

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6

The Two Knights Defense, avoiding the Evans Gambit and lesser gambits like the Jerome.

4.b4 

Philidor1792 wishes to have his gambit anyway!

This move makes me wonder why we haven't seen this gambit against the Hungarian Defense, i.e. 3...Be7 4.b4!? as if the pawn is captured, the game becomes and Evans Gambit after all.

In the text, White enters an Evans Gambit a move down, as Black's Bishop comes to b4 in one move, not the usual two. Philidor1792 doesn't fret over such trivialities.

4...Bxb4 5.c3 Be7 6.Bxf7+ 



Adding a dash of Jerome...

6...Kxf7 7.Nxe5+ 

...and a splash of the Halloween Gambit, to top it off.

7...Nxe5 8.d4 Nc6 

9.e5 Ng8 10.f4 d5 11.f5 Bh4+ 12.g3 Bg5 13.Qh5+ g6 



14.Qxg5

White is not afraid to enter an endgame with the pawns against Black's extra piece, but in this instance he might have had better chances (compared to the game) after 14.fxg6+!? Kg7 15.Bxg5 Qe8 16.0–0 hxg6 17.Bf6+ Nxf6 18.exf6+ Kf7 19.Qxd5+, although Black would still be objectively ahead.

14...Qxg5 15.Bxg5 Bxf5 16.0-0 Ke6 17.Nd2 h6 18.Be3 Nge7


19.Nb3 b6 20.a4

Looking for open lines and play on the Queenside.

20...Raf8 21.a5 Bc2 22.Nd2 Nf5 23.Bf2 Bd3 24.Rfc1 Rf7 25.axb6 axb6 26.g4 Nfe7 




27.Be3 h5 

Looking for open lines and play on the Kingside.

28.h3 hxg4 29.hxg4 Rh4 30.Kg2 Rxg4+ 31.Kh3 Re4 32.Re1 Rh7+ 33.Kg3 Nf5+ 34.Kf3 Rh3+ 35.Kg2 Rhxe3 36.Nxe4 Bxe4+ 37.Kf2 Rxc3 38.Rg1 Nfxd4 39.Ra8 Nxe5 40.Re8+ Kf6 41.Rc8 b5 White resigned

Alas, no victory today for the Evans / Jerome / Halloween pawns.

Counter-Gambit Rumble


While it has been suggested that "the best way to refute a gambit is to accept it", there are those who prefer to go one step further, and offer their own aggressive gambit in turn.

Philidor1792 - Stranger
Casual Game, Chess-Samara.ru, 2014

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 


About 4 years ago this blog discussed ways to approach this move (instead of 4...Bc5) in "Jerome Gambit vs Two Knights Defense" Parts 1, 2, 3, 4.

4.Bxf7+ 


As we have seen earlier in Philidor1792's play, after the alternative 4.Bb3 Bc5 5.Bxf7+ we would have a Delayed Jerome Gambit (see "Jerome Gambit-Inspired Play (Part 4)")


An early peek at this 4.Bxf7+ line occurred in "What's Going On Here?", and an early game was presented in "Opening Tale"; but much of what is in The Database on this line is from Philidor1792's games. (In some, below, he appears as "You".)

By the way, all of the referenced games can now be found in The Database.


4...Kxf7 5.Nxe5+


Some alternatives:


5.c3 Bc5 6.d4 in sTpny - yimansmellsbad, FICS, 2011 (0-1, 28); 


5.Ng5+ in caovas - tomi36, 1 1 blitz, lichess.org, 2013 (1-0, 27) and KillerBishop - TheMentalist, 40 5, lichess.org, 2013 (0-1, 17); 


5.d4 d5 (5...exd4 6.e5, yorgos - perrypawnpusher, blitz, FICS 2009, [1-0, 48]) in tomas2013 - tomi36, 1 2 blitz, lichess.org, 2013 (1-0, 22);


5.d3 d5 (5... d6 in viejoasquerosos - Killyourking, Redhotpawn.com, 2004 [0-1, 27]) cnselway - boycey, net-chess.com, 2001 (0-1, 11); and, finally


5.0-0 Bc5 6.Nc3,  leobrazer - perrypawnpusher, blitz, FICS, 2009 (0-1, 48), transposes into a variation of the Italian Four Knights Jerome Gambit. 


5...Nxe5 6.d4 Neg4 


The alternative 6...Ng6 (met with 7.e5) was seen in Philidor1792 - Guest805466, 3 1 blitz, PlayChessBase.com, 2014 (1-0, 62);  You-Stranger, blitz, Chess-Samara.ru, 2014 (1-0, 16)) You - Stranger, blitz, Chess-Samara.ru, 2014 (1-0, 17);  Philidor1792 - guest1278, blitz, www.bereg.ru, 2014 (1-0, 29); Philidor1792 - Guest691264, 3 0 blitz, Play.ChessBase.com, 2014 (1-0, 14); and Philidor1792 - Juppzupp, 3 0 blitz, PlayChessBase.com, 2014 (1-0, 24).


Instead, 6...Nc6 (also met by 7.e5) was seen in Philidor1792 - guest345, blitz, www.bereg.ru, 2014 (1-0, 15);  Philidor1792 - guest3018, blitz, www.bereg.ru, 2014 (½-½, 24);  Philidor1792 - guest1334, blitz, www.bereg.ru, 2014 (1-0, 20); You - Stranger, blitz, Chess-Samara.ru, 2014 (1-0, 18); and Philidor1792 - Guest292640, 5 0 blitz, PlayChessBase.com, 2014 (1-0, 50).


Also seen was 6...Nc4 (also met with 7.e5You - Stranger, blitz, Chess-Samara.ru, 2014 (1-0, 26). 


7.e5 Nxf2 


I hope Readers have stayed through all of the history and games above, as this game is about to get very violent. After all, Black has two extra pieces, and he can use them as he wishes.

8.Kxf2 Ne4+ 9.Ke1 Qh4+ 10.g3 Nxg3 11.Qf3+



11...Nf5+ 12.Kd1 g6 13.c3 Bh6 14.Bxh6 Qxh6 15.Nd2 Kg7



Black's counter-attack has slowed, but he still has the advantage - starting with a safer King.


16.Ne4 Ne3+ 17.Ke2 Rf8 


At this point, Black's plans begin to go haywire - shortness of time?


18.Qxe3 Qxe3+ 19.Kxe3 


The game is even - but not for long.


19...d5 20.Nf6 Bf5 21.Nxd5 Be4 22.Kxe4 c6 




23.Nc7 g5 24.Nxa8 Rxa8 25.Rhf1 h5 26.Rf6 Rh8 27.Raf1 Black resigned

Think Fast!


Here we have another collection of blitz games by Philidor 1792, fuelled by ideas from the Jerome Gambit, but launched in some Two Knights Defenses... Beware the attack! And - if you successfully defend - ask not for whom the time clock ticks, it ticks for thee!

More Jerome-Inspired Games (Part 4)


In the following 3-minute game, White only head-fakes toward a Jerome Gambit, but the resulting opening still features a piece-for-a-pawn sacrifice, and some foot soldiers who would not be out of place in Jerome's Double Opening.
