Jerome Gambit: Against the Titans (Part 1)

Image result for free clip art titan

Sitting at the computer the other day, I suddenly decided to challenge one of the programs to game of chess. I played the Jerome Gambit, of course. I've done this before - see "Jerome Gambit: Artificial Piffle" and "Contempt?!

Quickly we raced toward one of the more deadly refutations, a trip down memory lane for me that was lined with past escapes - and non-escapes. Suddenly, my opponent came up with a novelty that undid all of its hard work. The rest of the game was a combination of me timidly moving forward, while the computer seemed to lose much sense of things. Come, see. 

perrypawnpusher - Chess Titans
casual game, 2019

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5. Nxe5+ Nxe5 6. Qh5+ Ke6 



7.Qf5+ Kd6 8.f4 Qh4+ 



The first example that I have found of this move appeared in the American Chess Magazine of June 1899, in a satirical piece titled "A CHESS SCRAP" by "R.F.", which presented a supposed new-fangled thing - a chess game played over the telephone. The move is not a joke, however.

Interestingly enough, when I reported on last year's game against Chess Titans, I noted
I was pretty sure that my opponent was not seriously booked up on the Jerome Gambit, and that the killer move 8...Qh4+!? was not going to show up now.
Back then, it played the insufficient 8...g6. This time, it appeared to be better prepared.

9.g3 Nf3+ 

Black can quietly remove his Queen to f6, but the text is more aggressive.

10.Kf1

I have also played 10.Kd1perrypawnpusher - electrahan, blitz, FICS, 2009 (1-0, 35); perrypawnpusher - Banassi, blitz, FICS, 2009 (1-0, 28); perrypawnpusher - fortytwooz, blitz, FICS, 2010 (1-0, 11); perrypawnpusher - javistas, blitz, FICS, 2010 (1-0, 11); and perrypawnpusher - thinan, blitz, FICS, 2010 (1-0, 11).

The text is best, but, it still leaves Black better.

10...Nxh2+

As I have suggested, "Black can get away with this, but it is not best."

I actually met 10...Qh3+ (likely a mouse slip) twice, perrypawnpusher - rjbriggs, blitz, FICS, 2011(1-0, 10) and perrypawnpusher - inansoy, blitz, FICS, 2014 (1-0, 51).

I have had trouble in the past with 10...Qh6 perrypawnpusher - Temmo, Jerome Gambit thematic, ChessWorld.net, 2008 (0-1, 43) and 10...Qf6 -  perrypawnpusher - james042665, blitz, FICS, 2008, (0-1, 18); and perrypawnpusher - HarlemKnight, blitz, FICS, 2014}(0-1, 24).

I was familiar with the text move, having found it in the game Born Loser - NN, 2005 (1-0, 37) in White's unique book, Unorthodox Chess (2005).

11.Kg2

11...Qd8 

An odd move. I have faced a number of alternatives:

11...Qg4 (probably best) in perrypawnpusher - jgknight, blitz, FICS, 2011 (1-0, 68);

11...Nf6 12.gxh4 in perrypawnpusher - mikelars, blitz, FICS 2011 (1-0, 12);

11...Qe7 12.Qd5 checkmate, perrypawnpusher - intssed, blitz, FICS, 2010 (1-0, 12);

11...Qh6 in perrypawnpusher - JTIV, blitz, FICS, 2010 (1-0, 32); 

11...Qf6 in perrypawnpusher - IlToscano, Chess.com, 2016 (1-0, 18); and

11...Ne7 in perrypawnpusher - constipatedguru, blitz, FICS, 2017 (1-0, 20)

12.Qd5+ 

This move is good and easy to find. After the game, however, Stockfish 10 recommended that I ignore both the Bishop on c5 and the Knight on h2, at least at first, and play 12.Nc3!? The point is that neither Black piece can move to safety effectively - and a couple of possible Bishop moves would lead to checkmate in 2 or 3 moves.

The computer recommends 12...Nf6, which falls right away to the fork 13.e5+. The alternative, 12...Qe8, simply allows 13.Qd5+, and the Bishop will fall next move, and the Knight soon thereafter. White is better, in any event, but the computer is always looking for a "better better."

12...Ke7 13.Qxc5+ d6

Jerome Gambit: Winning Ugly is Still Better Than Losing Ugly (Part 1)

Zombie face vector graphics
Whew.

I just finished another Jerome Gambit game in the third round of the Giuoco Piano Thematic tournament at Chess.com, It was not pretty at all. You could say that I was losing - up until my opponent resigned. Of course, that is the "objective" evaluation of the Jerome, anyhow.

Yeah.

perrypawnpusher - IlToscano
Giuoco Piano Thematic, Chess.com, 2017

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.f4 Qf6 



This defense is solid and good. It also avoids the complexities of 8...Qh4+, which I faced in perrypawnpusher - constipatedguru, blitz, FICS, 2017 (1-0, 20).

9.fxe5+ Qxe5 10.Qf3 

Staying away from 10.Qxe5+ which has given me mixed results, and a loss most recently: perrypawnpusher - djdave28, Italian Game Tournament, Chess.com, 2014, (1-0, 22); perrypawnpusher - djdave28, Italian Game Tournament, Chess.com 2015, (1-0, 32); and perrypawnpusher - Altotemmi, Giuoco Piano Tournament, Chess.com, 2016, (0-1, 51) 

10...Nf6 

Easily an improvement over 10...Ke7, which I faced in perrypawnpusher - gtomlinson, blitz, FICS, 2007 (1-0, 28) and 10...h6, which I faced in perrypawnpusher - paulpee, blitz, FICS, 2012 (1-0, 71).

11.d3 

About the same as 11.Nc3 as in perrypawnpusher - Dogyou, blitz, FICS, 2009 (1-0, 21). 

11...Kc6 

Black wishes to avoid the embarassment of getting his Queen pinned to his King - a trick that might work in blitz (see below) but this game was played at 3 days per move.

Or Black could play 11...Ke7 as in perrypawnpusher - PREMK, blitz, FICS, 2005(1-0, 14); perrypawnpusher - karleinkarl, blitz, FICS, 2012 (0-1, 16);  and perrypawnpusher - vz721, Italian Game thematic, Chess.com, 2013 (1-0, 29); 

Or 11...Rf8 as in perrypawnpusher - BronxBoyII, blitz, FICS, 2009 (1-0, 18); perrypawnpusher - udofink, blitz, FICS, 2010 (1-0, 13);  perrypawnpusher - mconst, blitz, FICS,  2010 (1-0, 42); and perrypawnpusher - recreation, blitz, FICS, 2011 (1-0, 13);  

Or 11...Bb4+ as in perrypawnpusher - ViennaMike, blitz, FICS, 2009 (1-0, 19); 

Or 11...Re8 as in perrypawnpusher - Estebang, blitz, FICS, 2009 (1-0, 28) 

Or 11...Bd4 as in perrypawnpusher - Rossgil, blitz, FICS, 2009 (1-0, 26) 

12.c3 Bb6 13.Bf4 Qh5 14.Nd2 

I was not pleased to see the Queens leave the board, but I didn't have a better idea.

14...Qxf3 15.Nxf3 d6 



I added all of the game links above to show that I was supposed to be familiar with this line, and therefore supposed to know what I was doing against IlToscano. Yet, he has done very well, and the one pawn that I have for my sacrificed Bishop is clearly inadequate compensation.

I decided that I should again do what far better players than me have done in similar Jerome Gambit situations - abandon the "attack at all costs" idea, and let my opponent, who has the advantage, do the attacking. If he was not going to slip up when defending, perhaps he might err when atacking? Psychology is always a part of Jerome play.

Jerome Gambit: Smitten

A bit of chess advice from C.J.S. Purdy: Examine moves that smite. In the following game my opponent shows some familiarity with the Jerome Gambit, and smites hard at my position - alas, at one point losing his footing, with less than successful results.

perrypawnpusher - constipatedguru
5 5 blitz, FICS, 2017

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 



4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6 7.Qf5+ Kd6 8.f4 Qh4+ 



Black ignores the (lack of) safety of his King as well as his attacked Knight, and plays a smiting move that is often dangerous to White.

9.g3 Nf3+

Again, a strong, attacking move.

10.Kf1 Nxh2+ 

Black can get away with this, but it is not best.

11.Kg2 Ne7 

But here he slips, although a number of my opponents have lost their way in the past as well:

11...Qe7 as in perrypawnpusher - intssed, blitz, FICS, 2010 (1-0, 12);

11...Qh6 as in perrypawnpusher - JTIV, blitz, FICS, 2010 (1-0, 32);

11...Qg4 (best) as in perrypawnpusher - jgknight, blitz, FICS, 2011 (1-0, 68);

11...Nf6 as in perrypawnpusher - mikelars, blitz, FICS, 2011 (1-0, 12); and

11...Qf6 as in perrypawnpusher - IlToscano, Chess.com, 2016 (1-0, 18).

12.Qe5+ Kc6 13.gxh4 Ng4 14.Qc3 Kb6




Black has two pieces for his Queen. It is not enough.

15.d4 Bd6 16.e5 Nd5 17.Qb3+ Bb4 18.Qxd5 



You have to know that if Bill Wall were playing the White pieces he would have played something like 18.Nc3!?

18...d6 19.c3 c6 20.Qf3 Black forfeited on time
