Jerome Gambit: His Trap Was Part of My Trap


The following game again brings up a topic of concern

I have previously mentioned FIDE Master Dennis Monokroussos' thoughtful website, The Chess Mind, and his down-to-earth query, Is there even a single trap for Black to fall into in the Jerome Gambit?
My response has been
With due respect to Dennis, at the club level the entire Jerome Gambit can be considered a "trap" - especially if we consider psychological aspects. Black must pay attention, even as he treasures his advantages, or they will evaporate. 
My recently-completed game against AndrewLLL, in the third round of the "Italian Game Battlefield" tournament at Chess.com, is an example of the defender setting a nefarious trap, only to discover that his trap was part of my trap...

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



The Italian Four Knights Jerome Gambit. The Database does not contain any games by Alonzo Wheeler Jerome with this line. I have played the line 60 times, scoring 74%.

 5...Kxf7 6.Nxe5+ Nxe5 7.d4 Bd6



8.dxe5 Bxe5 

There is definitely something strange about this opening line of play - at least as far as I am concerned.

I recently posted a game where I now played 9.f4 -  perrypawnpusher - joseluizlopez, blitz, FICS, 2012 (0-1, 55) - that I had somehow overlooked posting 8 years ago.

In preparing for this post, I noticed that I had also not posted perrypawnpusher - lixuanxuan, blitz, FICS, 2014 (1-0, 22), where I explored 9.Bg5. I will fix that oversight soon. (The Database has 12 games with the move with White scoring 42%)

9.Ne2

After the suffering at the hands of joseluizlopez (see "Jerome Gambit: Another Historical 'Oversight' "), I made a note to try something that would keep my pawn structure intact. Little did I realize how odd the pawns would become.

9...c6 10.f4 Bc7 11.e5 Nd5 12.O-O Re8 



Black begins to castle-by-hand and is better, having a piece for a pawn.

White focuses on Blacks backward d-pawn, that blocks the light-squared Bishop, which, in turn, hems in the Rook. It is not enough compensation, but it is something to work on.

13.c4 Ne7 14.c5 b6 15.b4 a5 



My pawns are trying to gang up on the enemy d-pawn. If I only had an extra move, I could put my Bishop on b2, and then play a2-a3, with the ability to keep my pawn chain intact. Of course, I can't play 16.a3 directly, as it would fall to the simple 16...axb4. I decided to develop my Bishop and hope for the best.

16.Bb2 axb4 17.Qd4 

The attacking battery along the a1-h8 diagonal has potential. It will take a little cooperation to become dangerous, but it's not chopped liver.

In the meantime, the Queen threatens to capture the pawn at b4.

She also threatens to blunder, which Black notices quickly.

17...bxc5 

Guarding the pawn at b5, and offering the one at c5, instead. Of course, 18.Qxc5? would now be punished by 18...Bb6, pinning and winning the Queen. 

Black had stronger defensive ideas available - after the game, Komodo 10 recommended the consistent 17...Kg8, completing castling and maintaining the advantage - but I suspect that the "Negative halo effect" took hold of AndrewLLL at this point, and he figured, "If this guy is dumb enough to play the Jerome Gambit, he's probably dumb enough to hang his Queen". So he set his trap.

18.e6+ 



Black resigned

I had not worked out the attack completely, but it is clear that Black must now play 18...Kxe6, when, after 19.f5+ Nxf5 20.Qe4+ Kd6 21.Rad1+, the end would be near. After 21...Nd4, the exchange sacrifice is easy to find (the time limit for this game was 3 days per move), and, with 22.Rxd4+ cxd4 23.Qxd4+ Ke6 Black's King will not be long for the world.
