Jerome Gambit: Artificial Piffle

Okay, I admit it, I was bored. I certainly was not up for a complex, multi-layered intellectual exercise. So, seeing a chessplaying program on my computer, I thought I would while away some time with it - and the Jerome Gambit.

It turns out that I did this once before, 7 years ago - see "Contempt?!" The game does not seem to be in The Database, however. Odd.

I think Microsoft created the Chess Titans program to introduce people to chess. In a world where the world champion would have little chance of defeating top silicon challengers, it turns out that my opponent the other day was not so strong. 

perrypawnpusher - Chess Titans
casual game, 2018

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ 

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

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.

For the record, 8.Nc3 was played by my son against the program years ago, in jon - Chess Titans, 2011 (1-0, 14). That game does not appear in The Database, either. (I will remedy.)

8...g6

I suppose that this was part of the computer's programming, to keep it "weak" - occasionally producing stunners like this.

9.Qxe5+ Kc6 10.Qxh8 

Taking the Rook is best. I got a great game soon after 10.Qd5+, however, frittering it all away and barely surviving to draw in perrypawnpusher - spontex, 8 8 blitz, FICS, 2009 (1/2-1/2, 59). 

10...Qf8 

I also faced 10...d6, leading to an interesting battle, in perrypawnpusher - vermifugo, blitz, FICS, 2014 (1-0, 38)

11.d4 Bxd4 12.Qxd4 h6 

Okay, if it can be said that there was any kind of thread running through this game, it is clear that by now, CT has lost it.

13.Qd5+ Kb6 14.Be3+ c5 15.b4 Qxf4 

I suppose if Chess Titans were my client, I would diagnose clinical depression. Still, there was nothing for Black to be excited about in the computer-recommended 15...Kc7 16.Nc3 Qg7 17.Qxc5+ Kd8 18.Bd4 Qe7 19.Qa5+ Ke8 20.O-O-O. 

16.Qxc5+ Ka6 17.Qa5 checkmate

Jerome Gambit: A Battle (Part 1)

After a series of Jerome Gambit games where either my opponent or I (once, both) blundered away our Queens (I will spare Readers, but include the games in The Database), I played the following exciting adventure.

As the nursery rhyme goes (the two characters can also be found in Lewis Carroll's chess-themed Through the Looking-Glas and What Alice found There)

Tweedledum and Tweedledee
    Agreed to have a battle...  

After playing almost 500 Jerome Gambit games, I again found myself in quite a battle. 

perrypawnpusher  - vermifugo
blitz, FICS, 2014

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6

Black was looking to hold on to both extra pieces.

7.Qf5+ Kd6 8.f4 g6 

This is not Black's best play, even if it conjurs up visions of the venerable Blackburne Defense (6...g6). Yet it leads to largely unexplored territory, and play can become very uncomfortable for White if he is not careful. It is worth exploring more in depth.

9.Qxe5+ Kc6 10.Qxh8 

At this point, the game UNPREDICTABLE - zaboulef, blitz, FICS, 2010 ended with Black's resignation. 

The earliest game (of four) that I have with this variation in The Database is perrypawnpusher - spontex, blitz, FICS, 2009 (½-½, 59), where White bypassed capturing the Rook and went after the Black King, instead, with 10.Qd5+. As I noted in "The Opponent",

It was better to take the Rook, although play remains complicated, if in White's favor.

10...d6

The more aggressive 10...Qh4+ (also reminiscent of Blackburne's play in his 1885 game) was seen in Ghandybh - DVBLTTN, Online chess, 2009 (1-0, 17). As I noted,

The problem is that Black's Kingside will fall apart faster.

Best for Black seems to be 10...Qe7.

11.Qxh7

What to do?

I have found my Queen at h8, early in the game after grabbing a Rook, about 25 times, and I have always feared it getting trapped, and eventually captured (see the introductory note to this game, although they refer to different lines of play). My first thought has always been to get Her Majesty out of confined spaces!

One lesson I should have learned from a closer look at Blackburne's Defense is that White's Queen often escapes through the middle of the board (after a well-timed Qd8) - or after blocking the diagonal of Black's dark-squared Bishop with d2-d4.

In the current game, White's best was 11.d4.

Yet, that is not the end of the discussion, as Black has several possible replies, including the straight-forward 11...Bb6, seen in UNPREDICTABLE - farhadk, blitz, FICS, 2009 (1-0, 21).

What is more fun to look at is 11.d4! Bh3!?, when Black continues to play in Blackburne style. Can White actually then take the Bishop with 12.gxh3 ?  If he does, he can face, among other things, the energetic counter-attack 12...Qh4+ 13.Kd1 Nf6!? 14.Qxa8 Qh5+

Analysis diagram





Here, Black has sacrificed a couple of Rooks for a couple of pawns, but it is hard for White to escape a draw - while avoiding checkmate (remember, this is a blitz game). 

Analyze with me (and Houdini): 15.Ke1 (Not 15.Kd2 Nxe4+ 16.Kd3 Qf3+ 17.Be3 [17.Kc4 d5#] 17...Nf2+ 18.Kd2 [18.Kc4 Qe2+ 19.Kb3 Qb5+ 20.Kc3 Qb4#; 18.Kc3 Qxe3+ 19.Kc4 d5#] 18...Ne4+ 19.Kd3 draw) 15...Qh4+ 16.Ke2! (16.Kf1 Bxd4 17.Ke2 Qf2+ 18.Kd3 Qf3+ 19.Kxd4 Qxe4+ 20.Kc3 Nd5+ 21.Kd2 Qg2+ 22.Kd3 Qf3+ 23.Kd2 draw; 16.Kd2 Qf2+ 17.Kd1 [17.Kc3 Qxd4+ 18.Kb3 Qb4#; 17.Kd3 Qxd4+ 18.Ke2 Qf2+ 19.Kd1 Qf3+ 20.Kd2 Nxe4+ 21.Ke1 Bf2+ 22.Kf1 Bg3+ 23.Kg1 Qf2#; 16.Kd1 Qh5+ 17.Ke1 Qh4+ 18.Ke2 as in the main line] 17...Qf3+ 18.Ke1 [18.Kd2 Nxe4+ 19.Ke1 Qxh1+ 20.Ke2 Qg2+ 21.Kd3 Qf1+ 22.Ke3 Qe1+ 23.Kf3 Qd1+ 24.Kxe4 Qxd4+ 25.Kf3 Qf2+ 26.Kg4 Qg2+ 27.Kh4 Bf2#] 18...Qxh1+ 19.Ke2 [19.Kf2 Nxe4+ 20.Ke2 Qg2+ 21.Kd3 Qf1+ 22.Ke3 Qf2+ 23.Kd3 Qxd4+ 24.Ke2 Qf2+ 25.Kd3 Qf1+ 26.Kxe4 Qe2+ 27.Be3 Qxe3#] 19...Qxh2+ 20.Kd1 Qg1+ 21.Ke2 Qg2+ 22.Ke1 Qxe4+ 23.Kd1 Qf3+ 24.Ke1 Bxd4 25.c4 a6-+) 16...Qh5+ 17.Kd3! Qf3+ 18.Be3!

Nd5 27.Qg8 b5+ 28.Ka3 Bxc3 29.Qa8+ Kd7 30.Qxd5 Bxa1+ 31.Qb3 and it looks like White may survive. What a mess!

All of the above suggests that White should answer 11.d4! Bh3!? with the sober 12.0-0!, when his King will be safe, and all of Black's problems - down the exchange and two pawns, unsafe King, two Bishops hanging - will remain. The computer suggests 12...Nf6 13.Qxd8 Bxd4+ 14.Kh1 Rxd8 15.gxh3 Nxe4, but what fun is there in that?

11...Bg4?! 

Development toward the enemy King, but more to the point would have been 11...Qe8! and White would have to give back a couple of pawns to free his Queen - again, while negotiating some very complex play (without Houdini's help, which I had after the game) - 12.e5 (12.d3 Nf6 13.Qh4 Nxe4!? 14.Kf1 Bf2 [14...Nf2 15.b4 g5 16.Qh7 Bg4 17.Nc3 Bxb4 18.Qg7 Nxh1 19.Rb1 a5 20.a3 Bc5 21.d4 unclear, perhaps even] 15.g3 Bc5 16.h3 g5 17.fxg5 Qf7+ 18.Bf4 Qd5 19.Rh2 Bf5 20.g4 Bg6 21.dxe4 Qxe4 22.Nd2 Qxf4+ 23.Rf2 Qe5 24.Nf3 Qxb2 25.Re1 Qxa2 26.Rfe2 b5 even, whew!) 12...dxe5 13.f5 Bxf5 14.Qh4± but White is still uncomfortable, say after 14...e4 15.b3 Rd8 (15...Qe5 16.Nc3 Nf6 17.Bb2 Ng4 18.0-0-0 Bf2 [18...Nf2 19.d4] 19.Qg5 Bd4 20.Rhf1 Nxh2 21.Rf4) 16.Bb2 Qd7! 17.Qf4 g5 18.Qe5 b6 19.b4 Bxb4 20.0-0 Bc5+ 21.Kh1.

Another Miniature from Brazil

I was pleased to grab another Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) game from Welton Vaz's "Chess, Science Fiction and Peace" blog. See also: "Xadrez, Ficção Cientifíca e Paz" and "Teach / Learn"

Ghandybh  - DVBLTTN 

Online Chess, 2009

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

The adventure begins!

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6

7.Qf5+

An earlier game of Welton's went 7.f4 g6 8.Qxe5+ Kf7 9.Qxh8 Qh4+ 10.g3 Qh6 11.Qc3 b6 12.d4 Be7 13.Qc4+ Kf8 14.0-0 c5 15.f5 Qe3+ 16.Bxe3 Black resigned, Ghandybh - duboak, Chess.com 2009

7...Kd6 8.f4 g6

Not a common move, and not a good one, either. Refutations look like 8...Qh4+ or 8...Qf6, not just kicking the White Queen in the shins.

9.Qxe5+ Kc6 10.Qxh8

Yes!

In a previous game I went chasing after butterflies, and caught nothing but a half point: 10.Qd5+ Kb6 11.Nc3 c6 12.Na4+ Kc7 13.Qe5+ Bd6 14.Qxh8 Qh4+ 15.g3 Qg4 16.Qxg8 Qf3 17.Rf1 Qxe4+ 18.Kd1 b5 19.Nc3 Qd4 20.Qxh7 Bb4 21.Qxg6 d6 22.Qd3 Bg4+ 23.Ne2 Qxd3 24.cxd3 Re8 25.Re1 c5 26.a3 Ba5 27.b4 cxb4 28.axb4 Bb6 29.Bb2 Bf2 30.d4 Bxe1 31.Kxe1 Rxe2+ 32.Kf1 Rxd2 33.Bc3 Rxh2 34.Rxa7+ Kb6 35.Rf7 Bh3+ 36.Kg1 Rg2+ 37.Kh1 Rxg3 38.Rf6 Rxc3 39.Rxd6+ Kc7 40.Rd5 Kc6 41.Rh5 Bg4 42.Rg5 Bf3+ 43.Kh2 Bd5 44.f5 Rc4 45.Rg6+ Kc7 46.Rg7+ Kd6 47.Rg6+ Kd7 48.Rg7+ Kd6 49.Rg6+ Ke7 50.Rb6 Rxb4 51.Kg3 Rxd4 52.Rxb5 Kf6 53.Kf2 Kxf5 54.Ke3 Re4+ 55.Kd3 Re5 56.Kd4 Re4+ 57.Kxd5 Re5+ 58.Kc4 Rxb5 59.Kxb5 draw, perrypawnpusher - spontex, FICS, 2009

10...Qh4+ 11.g3 Qh3

White's move is more aggressive than duobak's Qh6 (above), because he plans to infiltrate the Kingside with his Queen. The problem is that Black's Kingside will fall apart faster.

12.Qxg8 Qg2 13.Qd5+ Kb6 14.Rf1

If Black's unsafe King isn't his undoing, being a Rook down will eventually finish him off.

14...Qxh2 15.Qb3+ Kc6 16.Na3 d5 17.Qb5+ Black resigned, as he is going to lose another piece (17...Kd6 18.e5+ followed by 19.Qxc5).

The Opponent

Whether it was Tarrasch, Tartakower or Znosko-Borovsky who said "Before the endgame, the gods have placed the middlegame," it seems equally important to note here that "Between the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) and a victory, stands the Opponent."

perrypawnpusher - spontex

blitz 8 8, FICS, 2009

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

4...Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6

7.Qf5+ Kd6 8.f4 g6 A new move, but not such a good one, as it returns too much material. Standard is 8...Qf6 or 8...Qh4+.

9.Qxe5+ Kc6 10.Qd5+

Going for the non-existent mate. It was better to take the Rook, although play remains complicated, if in White's favor, after 10.Qxh8 Qe7 11.Nc3 Nf6 12.e5.

10...Kb6 11.Nc3 c6

This move helps White get back on track. After the game Rybka 3 suggested: 11...a5 12.Na4+ Ka7 13.Qxc5+ b6 14.Qd4 Ne7.

12.Na4+ Kc7 13.Qe5+ Bd6 14.Qxh8 Qh4+ 15.g3 Qg4

A very interesting offer of even more material, with the opportunity to muddy things up. A reasonable response for White now is 16.d3.

16.Qxg8 Qf3 17.Rf1 Qxe4+ 18.Kd1 b5

Too generous: 18...Qxa4 was the right move, leaving White up the exchange and a pawn.

19.Nc3 Qd4

More mischief was available with: 19...Qg2 20.Re1 Qxh2 21.d4 Qxg3 22.Qxh7 Ba6.

The annoying thing was that I was a Rook ahead, and it didn't feel at all like I was winning.

20.Qxh7 Bb4 21.Qxg6 d6 22.Qd3

To put an end to Black's dangerous piece play, although 22.Ne4 was clearly stronger.

22...Bg4+ 23.Ne2 Qxd3 24.cxd3 Re8 25.Re1 c5

26.a3 Ba5 27.b4 cxb4 28.axb4 Bb6 29.Bb2 Bf2

My opponent refused to roll over and play dead. Still, 30.Kc2 would limit my damages now.

30.d4 Bxe1 31.Kxe1 Rxe2+ 32.Kf1 Rxd2 33.Bc3 Rxh2 34.Rxa7+ Kb6

Well, okay, White still has an advantage. A small one.

35.Rf7 Bh3+ 36.Kg1 Rg2+ 37.Kh1 Rxg3 38.Rf6

How to explain this move?? Would you believe that my dog, Ginger, was pestering me to go outside, so I made a move quickly – and then watched my Bishop disappear.
38...Rxc3 39.Rxd6+ Kc7 40.Rd5 Kc6 41.Rh5 Bg4 42.Rg5 Bf3+ 43.Kh2 Bd5 44.f5



And here we have what might be guessed to be a "typical" Jerome Gambit endgame, where White has two pawns against Black's piece. The one problem: White's game is lost.


44...Rc4 45.Rg6+ Kc7 46.Rg7+ Kd6 47.Rg6+ Kd7 48.Rg7+ Kd6 49.Rg6+ Ke7 50.Rb6 Rxb4 51.Kg3 Rxd4


An unfortunate slip, levelling the game: 51...Kd7 52.Kf4 Kc7 was much better.

52.Rxb5 Kf6 53.Kf2 Kxf5 54.Ke3 Re4+ 55.Kd3 Re5 56.Kd4 Re4+ 57.Kxd5 Re5+ 58.Kc4 Rxb5 59.Kxb5 Drawn
Hats off and a firm handshake to spontex, for a fight to the finish.
