Jerome Gambit: Win, How? (Part 2)

[continued from previous post]

perrypawnpusher - schnappa
Italian Game Classic, Chess.com, 2019

11.d3

Alonzo Wheeler Jerome played this move, with a transparent threat to pin and win Black's Queen, in games against Shinkman in 1874 (0-1, 21), Brownson in 1875 (1-0, 42), Amateur in 1876 (1-0, 20) and Pane in 1878 (1-0, 41). The Database has 9 games where Black overlooked the threat and lost his Queen - 7 of those wins were mine.

11...Ke7 

The Chess.com analysis rated 11...Ke7 to be an  "inaccuracy" (The Database: 11 games, White scores 64%), seeing 11...Kc6 as best (The Database: 11 games, White scores 27%).

The alternative, 11...Kc6, attributed to B.K. Neufville, “gives Black an opportunity for a counter attack and makes an exciting contest” according to Jerome, in the American Chess Journal, of April 1878.

12.Nc3

An "inaccuracy", according to the analysis, which considered 12.c3 as "best".

I should give the alternative title of "Jerome Gambit Secrets #10" to the current post, as The Database shows only 1 game with 12.c3, and it continued 12...d6 13.Bg5? Qxg5 White resigned, which was a result quite likely to keep the variation "secret".

12...d6 

This move was "inaccurate"; 12...Bd4 was "best".

(If you are getting tired of all of this "inaccurate" stuff, so am I. Considering the whole game, the computer assessed me as being 91.9% "accurate", while my opponent was  89.7% "accurate". I don't know what that means.)

The latter move, 12...Bd4, was played against me in perrypawnpusher - karleinkarl, blitz, FICS, 2012 (0-1, 16), a sad game where, in a bit of an echo, I allowed Black to pin my Queen to my King.

13.Bf4 

So far, we are following Jerome - Brownson, Iowa, 1875, which continued 13.Bf4 Qe6 14.O-O-O Qg4 15.Qf1 g5 16.Bg3 Be3+ 17.Kb1 Bf4 18.Bf2 c5 19.h3 Qh5 20.h4 Be6 21.hxg5 Qxg5 22.Bh4 Qg4 23.Nd5+ Bxd5 24.exd5 Rae8 25.d4 Bg5 26.Bxg5 Qxg5 27.dxc5 dxc5 28.Qb5 b6 29.d6+ Kf7 30.Rhf1 Kg7 31.Qc6 Rhf8 32.a3 Rd8 33.g4 Nxg4 34.Qc7+ Kg8 35.Rxf8+ Rxf8 36.Qxa7 Qd8 37.Qa4 Ne5 38.Qe4 Ng6 39.Qe6+ Rf7 40.d7 Nf8 41.Qe8 Qxd7 42.Rxd7 Rxd7 43.Qb8 Black resigned

13...Qh5

The Chess.com analysis announced "inaccuracy", preferring 13...Qd4 (which does not show up in The Database at all) as "best".

In perrypawnpusher - vz721 -Italian Game thematic, Chess.com, 2013, I now castled Queenside, allowing the exchange of Queens. Looking over that game while I was putting together this post, I was shocked to see that both I and my opponent seem to have overlooked the response 14...Bg4!?


In any event, against schnappa I now played the kind of move that you would more likely see in a 1 0 bullet game, just to mess with my opponent ("threatening" to remove his Knight at f6, which protects his Queen) and give me time to figure out if I wanted to swap Queens, after all.

14.Nd5+ 

And here, much to my surprise, Black resigned.

Of course, 14...Nxd5? would be a mistake, but any reasonable King retreat - 14...Kd8, 14...Kf7 or 14...Kf8 - would be fine. He should avoid 14...Ke6, which would allow the fork 15.Nxc7+, and both 14...Kd7? and 14...Ke8? (resurrecting the primary threat) would fall to 15.Nxf6+.

The Chess.com analysis rated the final position as -2.29, giving Black over a 2 pawn advantage, which makes sense to me.

It recommended the following continuation: 14...Kf7 15.Qxh5+ Nxh5 16.Rf1 Nxf4 17.Rxf4+
 Kg6 18.Nxc7 Rb8 19.Kd2 Bd4 20.Raf1 Be5 21.R4f2 b5 22.Nd5 Be6 23.Ne7+ Kg5 24.Nc6 Rbc8 25.h4+ Kh6 26.Nxe5 dxe5 27.a3 Kg6 28.g3


My best guess is that demands of the outside world temporarily distracted my opponent.

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

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.

Chess.com Italian Game Tournament Finish

As expected, JoseSoza of Chile won the recently completed Italian Game Tournament at Chess.com with a record of 17 wins, one loss, and 7 draws. Congratulations on such an achievement!

Second place was taken by vz721 of Russia, with a record of 15 wins, 4 losses and 1 draw. Fighting play, and the second highest number of wins!

Third place was taken by perrypawnpusher of the U.S.A. (that's me), with a record of 13 wins, 6 losses, and 5 draws.

The tournament was a 4-round affair, starting with 20 players in 5 groups, with the top players advancing each round. While the first round had 5 groups of four, the second round had 3 groups of 3 and one of four, and the third round had 1 group of three and 1 group of four. This allowed for different numbers of games played for different finalists.

I tallied 5 - 3 with the Jerome Gambit - two losses to JoseSoza, one to vz721.

(A Random Note: May, 2011, was the month, so far, with the most page views for this blog, since it started in June, 2008 . However, this month, November 2013, is racing toward the top and likely will overtake it! My "Welcome!" and "Thank You! to everyone stopping by. - Rick) 

Who's the "Expert"?

The following game made me wonder, who knows the Jerome Gambit better, him or me? The outcome was surely suggestive!

perrypawnpusher - vz721
Italian Game thematic, Chess.com, 2013

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 9.fxe5+ Qxe5 10.Qf3 Nf6 11.d3

I have sometimes referred to this as the "optical illusion" variation (see here and here for starters) because of the number of times in blitz play that my opponents have relaxed and allowed me to pin their Queen to their King.

In the April 1874 issue of the Dubuque Chess Journal, Alonzo Wheeler Jerome wrote that 11.d3 compelled either King or Queen to move as White threatens Bf4; or Black can play ...g5. 

He was referring to the game Jerome - Shinkman, Iowa, 1874, which appeared in the July 1874 issue of the DCJ, and indeed, the game continued 11...Ke7 12.Nc3 g5; although after White's 21st move he wrote "and Mr. Shinkman announced loss of the Queen or mate in six moves." Ouch.

11...Ke7 12.Nc3 d6 13.Bf4 

So far, following Jerome - Brownson, Iowa, 1875, (1-0, 43).

13...Qh5

An interesting improvement on Brownson's 13...Qe6, which allowed Jerome to play 14.0-0-0 and then meet 14...Qg4 with 15.Qf1. White doesn't have a great position, but he keeps the Queens on the board.

14.0-0-0 Qxf3 15.gxf3 Be6 16.d4 Bb4 

At first I was happy with my pawn center. It grabs space, and threatens to advance, feeding an attack on the King. However, I decided to "hold" the center, instead, and my pawn chain became frozen - and my opponent started hammering it.

17.d5 Bf7 18.Nb5 Kd7 19.Nd4 Rae8 20.Nf5 Rhg8

21.h4 Bg6 22.Nd4 Nh5 23.Bh2 Bc5 24.Rhe1 Bxd4 25.Rxd4 Rgf8 

All the "dynamic" aspects of the pawn center have been removed.

26.Rd3 Nf4 27.Rd2 Bh5 28.Re3 Ng6 29.Rf2 Nxh4 White resigned

I might have been able to get 30.f4 in here, but that was about as mobile as my center was going to get. It looked like nothing more than suffering to me, so I turned my  attention to my remaining games.

Very nicely played, Vlad! 

KO

Well, that was quick.

As mentioned in the last post, my Jerome Gambit game against vz721 in the Chess.com Italian Game Thematic Tournament (see "Started"), was staggering towards and unhappy ending, and has now ended with a "knockout" - a 29-move loss.

I have a little time, while defending an Evans Gambit against MarkHundleby1 (with the same moves as in my other game, with Black, against vz721), to repair my favorite opening.

Do I suspect that MarkHundleby1 will allow me to play 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+? It's a good bet. He is obviously aware of the play of the games around him in the tournament. Why wouldn't he want to wander down easy street and follow vz721's lead?

Tourney Update

Play has been pretty fast and furious for me in the Chess.com Italian Game Thematic Tournament (see "Started").

I have drawn both my games against top-rated JoseSoza, the two completed games so far.

However, vz721, one sharp player (second-rated in our quad), improved on some of Alonzo Wheeler Jerome's original analysis (!) and has been treating my one Jerome Gambit rather harshly. I am currently hanging in there, but the phrase "punch drunk" comes to mind...

With Black against MarkHundleby1, I am defending well against his Evans Gambit. When that is complete, I will have my last chance at a Jerome Gambit - and therein lies an interesting tale for a later date.

Started!

The fourth and final round of the Chess.com Italian Game thematic tournament has started, and there are four competitors: JoseSoza of Chile, vz721 of Russia, MarkHundleby1 of Canada, and yours truly, perrypawnpusher of the USA.

This presented as many as three more opportunities to defend the "honor" of the Jerome Gambit 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+, depending on how my opponents wished to defend.

So far, JoseSoza has declined the Jerome with 3...Be7, choosing the Hungarian Defense. This is his second "pass" after scoring two wins against my Gambit in rounds one and two.

On the other hand, vz721 has allowed it with 3...Bc5, and I was quick to sacrifice the Bishop! Let us hope this is not another example of Act in haste, Repent at leisure.

I have Black against MarkHundleby1 right now (defending against the Evans Gambit; alas, not the Evans Jerome Gambit), so the chance for a Jerome Gambit has to wait - unless he plays it against me!

The results, as for previous rounds, come what may, will be reported.
