Jerome Gambit: Folie a Deux (Part 1)

Paranoid schizophrenia - Wikipedia

I won my third round game - an Italian Four Knights Jerome Gambit - in the "Italian game Classic" tournament at Chess.com, when my opponent and I seemed to have the same "hallucination" about a tense, tactical position. Up until then, I had been awkwardly struggling to lurch my way back to equality - only to be smacked around by a violent return of my sacrificed material.

Given the distracted level of my play, I consider myself quite lucky.

perrypawnpusher - Sp1derR1c0
Italian Game Classic, Chess.com, 2020

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

Whew! My game against Winawer99 in the same round continued 4...Nxe4, and I decided to avoid my past suffering with the Noa Gambit / Monck Gambit / Open Italian Four Knights Jerome Gambit - 5.Bxf7+ - and played, instead, 5.Nxe4 d5 6.Bd3 dxe4 7.Bxe4 Bd6 8.Bxc6+ bxc6 9.d4, a line that I also have struggled with. It showed: on my way to a possibly drawn Bishops-of-opposite-colors endgame, I overlooked a checkmate in 2 moves (0-1, 21).

5.Bxf7+ 

The Italian Four Knights Jerome Gambit.

What difference does the addition of Knights at c3 and f6 make, when compared to the regular Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+)?

Komodo 10 shows it to improve Black's position by about 3/4 of a pawn.

The Database has 2,731 games with the Four Knights version, with Black scoring 61%. This compares to 15,157 games with the Jerome, proper, with Black scoring 54%.

I have to admit, in my own games, Black scores 25% in my Italian Four Knights Jerome Gambit games (62) versus scoring 17% in my regular Jerome Gambit games (336). 

5...Kxf7 6.Nxe5+ Nxe5 7.d4 Re8



I like this move. Instead of worrying which piece to save, Black develops another one, on a crucial file. Let White figure it out!

8.dxc5 

In preparing this post, I was amused to discover that Komodo 10's second choice, here, was not a capture, but 8.0-0, fully relying on the fact that not all of the pieces will be able to escape, e.g. 8...Bd6 9.f4!? Nc6 10.e5, etc. 

That line, in turn, raised a question for me: Has anyone ever tried moving the f-pawn right away, i.e. 8.f4 ? It turns out that The Database has two examples - Svirfneblin - cosmoo, blitz, FICS, 2011 (1-0, 24) and Mvskoke - Panico, blitz, FICS, 2012 (1-0, 36). It is an example of going too far, however, as Black has 8...Bxd4 9.Qxd4 Nc6 and he is doing better than in the normal lines.

By the way, The Database has 6 games with 8.0-0 (Black scores 56%) - and in 3 of them, Svirfneblin had the White pieces. I will have to look at more of his games...


8...Kg8 

Finishing castling-by-hand. I have noted
This is an improvement over 8...Nc6 of perrypawnpusher - hudders, blitz, FICS, 2010 (1-0, 13) and 8...Nc4 of the tragic perrypawnpusher - TrentonTheSecond, blitz, FICS, 2010 (0-1, 9),
9.O-O d6 10.cxd6 cxd6 



This is probably an improvement over 10...Qxd6, which I faced a couple of times perrypawnpusher - hklett, blitz, FICS, 2013 (1-0, 31) and perrypawnpusher - strandskatan, blitz, FICS, 2013 (1-0, 38). I was prepared, sort of
After the game Houdini recommended the dull 11.Qxd6 cxd6 12.Rd1 with pressure against Black's d-pawn, although Black is still better.
11.Be3 

An odd move; the Bishop usually goes to g5. I was planning to play f2-f4, but, for some reason I was worried about ...Qb6+ at some point, so I protected the a7-g1 diagonal. Of course, White's b-pawn is not vulnerable to that enemy double attack, until the Bishop moves. I suspect Caffeine Deficiency Disorder.

11...Be6 12.f3 

This is the move that White sometimes plays when he gives up on his plan to attack, and decides to hunker down and challenge Black to do something with his material advantage. Suddenly - comparatively, as the time control was 3 days per move - that became my plan.

The word "collywobbles" comes to mind.

New to the Jerome Gambit Gemeinde

I hope that you enjoyed yesterday's game. I have brought back the same contestants for a second Italian Four Knights Jerome Gambit, played on the same day. Mvskoke has played over a dozen Jerome Gambits this year, and they all are interesting.


Mvskoke - trss
blitz, FICS, 2012


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




5...Kxf7 6.Nxe5+ Nxe5 7.d4 Bxd4 8.Qxd4 d6 




9.f4


More aggressive than yesterday's 9.0-0, although they could transpose.


9...Nc6 


In another outing, play continued 9...Neg4 10.0-0 Qe7 11.h3 Nh6 12.e5 Nd7 13.Nd5 Qh4 14.Nxc7 Nf5 15.e6+ Kg6 16.Qd1 Ne3 17.Qd3+ Nf5 18.exd7 Bxd7 19.Nxa8 Kf6 20.Bd2 a6 21.Nc7 Bc6 22.Bc3+ Kg6 23.Rae1 Bd7 24.Nd5 Kh6 25.Rf3 Bb5 26.Qxf5 g6 27.Qg5+ Qxg5 28.fxg5+ Kh5 29.b3 Bc6 30.Nf4+ Kh4 31.g3+ Kxg5 32.Ne6+ Kh5 33.g4+ Kh4 34.Rf7 Re8 35.Rxh7+ Kg3 36.Bd2 Bd5 37.Bf4+ Kf3 38.Nd4+ Kxf4 39.Rxe8 g5 40.Nf5 Kf3 41.Re3+ Kf4 42.Rd7 b5 43.Rxd6 b4 44.Rxd5 a5 45.Red3 a4 46.R5d4+ Ke5 47.Re3+ Kf6 48.Rd6+ Kf7 49.Re7+ Black forfeited on time.Mvskoke - ClaytonBigsby, FICS, 2012 


10.Qc4+ Be6 11.Qb5 Nd4 





A tough game followed 11...Rb8, i.e., 12.f5 Bd7 13.Qc4+ Kf8 14.Bg5 Ne5 15.Qe2 c6 16.0-0 Kf7 17.h3 Re8 18.g4 Kg8 19.Bh4 Rf8 20.Bf2 c5 21.g5 Ne8 22.h4 a6 23.Rad1 Qc7 24.Nd5 Qd8 25.Bg3 Nc7 26.f6 Nxd5 27.Bxe5 dxe5 28.Rxd5 Qc7 29.f7+ Rxf7 30.Rxf7 Kxf7 31.Qf3+ Kg8 32.Qc3 Re8 33.h5 b6 34.b4 Bc6 35.Rd1 cxb4 36.Qc4+ Kh8 37.h6 Rc8 38.Qe6 Bxe4 39.Rd6 Qc5+ 40.Kh2 Qf2+ 41.Kh3 Bf5+ White resigned, Mvskoke - malick, FICS, 2012 


12.Qd3 b5


This is a difficult move to understand. Perhaps it is a mouse slip?


13.Qxd4 c5 14.Qd1 b4 15.Nd5 Nxe4 




Black should have been thinking about the vulnerability of his opponent's King, and tried 15...Bxd5 16.exd5 Re8+. Now the advantage shifts to White, and he works to increase it.


16.0-0 Bf5 17.Ne3 Qf6


This does not save the endangered Bishop.


18.Qd5+ Qe6 19.Qxf5+ Qxf5 20.Nxf5 Ke6 




White's extra piece is enough for the full point.


21.Nxg7+ Kd5 22.f5 Rhg8 23.Ne6 Rac8 24.Bh6 Rg4 25.Rae1 Rcg8 26.Nf4+ Ke5 27.f6 Kd4 28.f7 Rxf4  Black resigned

Sometimes People Don't Think Like Computers

I like to consult with a computer program when I prepare games for posting on this blog. Often Rybka or Houdini point out tactical oversights. Sometimes, though, they make recommendations that are terribly esoteric, like in the following game, and I am forced to conclude, once again, that sometimes people don't think like computers...


Mvskoke - trss
blitz, FICS, 2012


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




The Italian Four Knights Jerome Gambit.


5...Kxf7 6.Nxe5+ Nxe5 7.d4 Bxd4 8.Qxd4 d6 




9.0-0 Nc6 10.Qa4 


Something new. Instead, 10.Qd3 would have transposed, after 10...Re8 11.Bg5, to the recent perrypawnpusher - JoseSoza, Chess.com, 2012 (0-1, 34)


10...Re8 11.Bg5 h6 12.f4 hxg5 13.fxg5 Kg8 14.gxf6 gxf6



According to Rybka, this leads to a slight edge for White. The computer recommends 14...Ne5 and a complicated follow up for a small edge for Black. 


15.Nd5 Rf8 16.Qb3 Be6 17.Qg3+ Kh7 




Stepping into the open is very dangerous. 


Rybka's recommendation leaves Black with a Rook and two minor pieces for his Queen and a couple of pawns, which is unclear: 17...Kf7 18.Rxf6+ Qxf6 19.Nxf6 Kxf6 20.Rf1+ Ke7 21.Qg5+ Ke8 22.Rxf8+ Kxf8 23.Qf6+ Bf7 24.Qh8+ Bg8 25.h4 Re8 26.Qh6+ Ke7 27.Qg5+ Kf7 28.Qf5+ Ke7 29.h5 Be6 30.Qf4 Rg8 31.h6.


I am not surprised that Black did not see this "escape". I don't think that regular club players think that way.


18.Rf4 f5 19.Rh4+ Qxh4 20.Qxh4+ Kg6 21.Nxc7 fxe4


22.Nxa8 Rxa8 23.Rf1 Bf5 24.g4 Black resigned
