It was not long after I began looking into the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) that I noticed one chess match kept turning up in the databases: in 1993, between the human Micah Fischer-Kirshner and the chess-playing program KnightStalker, an early version of Fritz. As luck would have it, I was able to interview Micah about his experience for this blog.
The Jerome Gambit seemed a natural for matches, especially ones involving computers. Jeroen_61 of the Netherlands ran one with Hiarcs, Junior 7, Shredder Paderdorn (6.02) and Fritz 7.
I tried a few myself, notably a Fritz8 vs Fritz5 encounter and a Delphi vs Wealk Delphi contest. Each attempt had its shortcomings. (Perhaps you read about them here.)
The mysterious "perfesser" played an introductory 4-game match with the Talking LCD Chess Gadget. Like the Jerome Gambit itself, it was good for some chuckles.
Topping all efforts so far, "RevvedUp" and his trusted companions Hiarcs 8, Shredder 8, Yace Paderborn, Crafty 19.19 and Fritz 8 explored the Jerome Gambit in a 30-game encounter. It was simply war.
And then there is that as yet untold tale of two expert-to-master-level American players who played a Jerome Gambit match 5 years ago, but the games remain hidden from public view, pending the players' release of a monograph on the opening...
Perhaps that will show up on this blog one of these days.

With over 1,200 daily posts to this blog to day, I sometimes like to wander back in time and see what things caught my interest over 3 years ago...
Of course, it all started with a "Welcome!"
It was not long before I had to address the objection "But - is this stuff playable??" (part i and part ii).
It was not surprising to find, among the early "Jerome Gambit Tournaments" some contests where both players lost the same game.
I let early Readers in on "Pitfall Numero Uno in the Jerome Gambit" and filled them in a bit on "What kind of a man...?" would conjure up such a gambit, one who became "The Man, The Myth, The Legend..."
I started gathering up Jerome Gambit mysteries that I still have not solved. " 'Tis A Puzzlement" was only the first list.
Explored was the link between the Jerome Gambit and the Salvio Gambit. Was there a link?
Then there was "Les Femmes des Echecs...& the Jerome Gambit" and the story of how this blog sidled up to the Jerome Gambit entry in Wikipedia...
All that, and a whole lot more, in only the first three months of this blog.
And there are many, many more Jerome Gambit tales to be told!
Friday's game ("A Not-so-Simple 'Simple Endgame'") was intense, with significant analysis; so today I thought I'd lighten up and present a more straight-forward game. Not "better played", just "less analyzed."
The jist of the game is that three "Jerome pawns" offset the enemy piece, while four "Jerome pawns" win against it.

The Semi-Italian Opening.

Played by habit. I have been meaning to explore the alternative 4.Nc3, although I probably would have wound up in the game continuation, any way, if my opponent had played 4...Nf6 (followed by 5...Bc5).

6...Kxf7 7.Nxe5+ Nxe5 8.d4 Neg4
I was surprised to see that The Database contained only one earlier example of this move.
9.dxc5 Qe7
I saw 9...Re8 in perrypawnpusher - GiantReign, blitz, FICS, 2010 (1-0, 20) The text is an improvement.
10.Qd4 d6 11.cxd6 cxd6 12.h3
After the game, Houdini suggested 12.f4 right away.
12...Ne5 13.f4 Ng6
What is "unusual" in this otherwise routine position is the isolated Black pawn at d6. That suggests that one plan of development for White would be b2-b3 followed by Bc1-a3. Even if further analysis showed that the pin on the pawn was not dangerous, White could play Bc1-b2, putting the Bishop on the a1-h8 diagonal.
14.Bd2 Rg8
This is most likely a mouse-slip, as the move is incomprehensible, while 14...Rf8, 14...Re8 and 14...Rd8 would all make sense. My opponent did not request a take-back (which I probably would have given) so I can not be sure of this.
15.Rae1 Qd7 16.Nd5 Nh5
I know that the "Jerome pawns" are beginning to look frisky, but this horsing around does not help Black.

19.Nxf6 gxf6 20.Qxf6+ Ke8 21.f5 Ne5 22.Bxe5 dxe5 23.Qxe5+ Qe7
White's lead in development has led to the win of two pawns, which meant that I had 4 pawns against Black's Bishop, enough for a winning endgame advantage. It would actually have been stronger for me to leave the Queens on the board, but my time was low (and had been so for a while) and I figured that I was more likely to overlook an enemy attack with Queens on the board.
24.Qxe7+ Kxe7 25.e5 h5 26.Rf4 Bb7 27.Rd1 Ba6 28.Kf2 hxg4 29.hxg4 Rh8
Black finds no answer for White's three connected, passed pawns.

More sense was to be found in 30.Kg3.

33...Rh3+ 34.Kd4 Bb7 35.f6+ Ke8 36.g7 Black resigned
Here is another short Jerome Gambit game from Bill Wall. It contains a motif that has showed up in recent posts – that of Ng5+ with an attack on Black's King as well as on a piece at e6 (see "Sunday Tournament Update" and "Ng5+") – and comes with a reminder that snap defensive moves can have long term consequences.
Bill has utilized the Qe2 attack before ("No Getting Around This Wall" is particularly interesting), so, for study purposes, I have included earlier games of his, even when he has played the move sooner than in the text. I have also included a number of games by hinders, of FICS, who played the line (with mixed success) a while back.

The ChessWorld Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) Thematic Tournament continues, with all of the players firing off moves and many of the games proving to be exciting, entertaining, and instructional affairs.
To date, over 40% of the games have been completed, with White scoring 39% – an unimpressive figure when compared, say, to the Ruy Lopez, but about as robust a number as has been seen in other thematic tournaments, and a downright hearty one for an opening that has several established refutations.
9 of the 210 games (4%, an astonishingly "high" number as compared to only about 9/10th-of-a-percent of the games in The Database) feature the Jerome Gambit Declined with either 4...Kf8 or 4...Ke7.
63 of the games, a full 30%, are developing along "classical" Jerome Gambit lines (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+), the highest that I have seen in a thematic tournament.
The remaining 138 games follow "modern" Jerome Gambit lines (not-5.Nxe5+).
The current leaders are mckenna215, with 12.5 points (out of 14 games) and braken, with 11.5 points (out of 17 games).
In a tournament where each player plays 28 games, however, just about anything can happen over the course of the marathon. For example, AsceticKingK9 has 10 points out of 10 games, an impressive 100% score so far. Not far behind is Rikiki00 with 9.5 points out of 12 games.
Neither martind1991 nor Luke Warm have lost (or completed) any games, so their "perfect" scores have not been marred, either.
In response to yesterday's post, "A Not-so-Simple 'Simple Endgame' ". I received an email from Jerome Gambit Gemeinde member Bill Wall, who had more to say on that particular endgame. (I've added some diagrams.)
Rick,
Interesting opposite-colored endgame. I've had a few myself and they are hard.
So White played 31.b4 c6 32.c4 Bd7?!
which seems to get the bishop out of play. I would have tried 32...Be6, attacking the pawn. After 33.c5, then 33...Bb3 should hold for a draw.
Another idea is 32...Bf1, attacking the pawn. If 33.b5 Bxc4 34.bxc6 bxc6 should draw. If 33.c5, then 33...Kg6 should be OK for Black.
So after 32...Bd7 33.Kd2 Kg7 34.Kd3
34...Kf7. Perhaps 34...Bf5+ first, and after 35.Kd4, then 35...Kf7.
Now in the game White plays 35.Kd4 and I think now Black loses after 35...Ke6?, allowing 36.Kc5! and winning.
So instead of 35...Ke6, Black should play 35...c5+!.
The pawn cannot be ignored. If 36 bxc5, then 36...Bxa4 should draw.
If 36.Kxc5 Bxa4.
If White plays 37.Bb8, then 37...Ke6 looks OK.
If White plays 37.Kb6, then 37...Bc6 should hold for the draw.
If White plays 37.b5, then 37...Bb3 should draw.
Bill
