History Mystery



From the Brooklyn Daily Eagle, March 1, 1900, page 14:

...Theodore M. Avery of Poly Prep encountered a team of the Manual Training School players in a simultaneous exhitition and won every game but one, which he drew. He defeated Caffall in a Scotch Gambit, Saunders in a Ruy Lopez; Baker and Fuchs, consulting, in a Max Lange; Lehman and Stillman, consulting, in a Two Knights Defense, and Steiner and Dennett, consulting, in a Jerome Gambit.

The Poly Prep Country Day School continues to this day in Brooklyn, New York, and I emailed Mr, Malcolm Farley, Director of Communications, to see if he could direct me to other sources of information about Avery's simultaneous exhibition.

Oh, and although the name "Steiner" leaps out to the eye as one of the players defending against the Jerome Gambit, the game took place several years before either Herman or Lajos Steiner were born...

Mr. Farley's response came quickly:

Dear Mr. Kennedy:

Many thanks for your interest in Poly Prep and its history.

As you know our school—which prepares students from nursery through 12th grade for college and for life—was founded in 1854. So, we have a long and storied past in Brooklyn.

Alas, our archivist has searched Poly’s extant records for 1900 and can find no information about Mr. Avery’s chess activities. Should we come across any such information in the future, we will forward it to you.

Once again, thank you.

Cordially yours,

Malcolm G. Farley

Boden-Kieseritzky-Jerome Gambit??


My fascination with the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) sometimes gets me into adventures that I really shouldn't be able to get out of...

perrypawnpusher - jayshanker
blitz game 12 0, FICS 2009

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6

Not everybody wants to play the Giuoco Piano with 3...Bc5. Lately I've been answering 2...Nf3 (the Petroff Defense) with 3.Bc4 and if 3...Nxe4 then 4.Nc3, the Boden-Kieseritzky Gambit (4...Nxc3 5.dxc3). So I figured in this game to transpose from the Two Knights Defense into the B-KG as well.

4.0-0 Nxe4 5.Nc3 f5

So far, so good, although Black's last move is quite unusual. Since a main defence against the Boden-Kieseritzky Gambit involves ...f6, protecting the black e5 pawn, White should be able to count on decent play after the text with 6.Re1.

Of course, that was not what I was thinking, as I had a case of Jerome-Gambit-on-the-brain...

6.Nxe4 fxe4 7.Nxe5 Nxe5 8.Qh5+


Not precisely Jerome-ish, as White retains his King Bishop, but the thematic foolish sacrifice of material for a dubious attack is recognizable.

8...g6

Tic tac toe! Once again, the "shock and awe" of responding to the sacrifice makes up for much of its theoretical un-soundness.

There should be more to a gambit idea than just crossing my fingers and hoping, as the following defense should have resolved the game quickly in my opponent's favor: 8...Ng6 9.Re1 Qh4! (I don't think I'll test my luck twice with this line.)

9.Qxe5+ Be7

10.Qxh8+ Bf8 11.d3 d6 12.Bh6 Kd7 13.Qxf8 Qxf8 14.Bxf8 Ke8

The rest is silence.

More of The Next Best Thing...

In his comment to "London Calling... Seven Months of Blog" and "The Next Best Thing..." Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) Gemeinde member Pete Banks ("blackburne") called readers attention to the opening 1.h4.

Would giving a couple of games by some top past masters give a different picture of the possibilities of that opening?

Nerves of Tin



I still play the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) in online blitz games and I still sometimes get a case of "nerves" when I do.

Good thing I still win...

perrypawnpusher - GabrielChime
blitz 12 0, FICS 2009
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6

7.Qf5+ Kd6 8.f4 Ng6
An unusual move – I have less than a half-dozen game examples in my database. That's the fun of defending against the Jerome Gambit, however: there are so many ways to give back a piece or two.

9.Qd5+ Ke7 10.Qxc5+ d6 11.Qe3
An alternative was 11.Qc3.

We have a typical Jerome Gambit position, where White has two pawns to make use of against Black's extra piece.
11...Bd7 12.0-0
Also equal (according to Fritz 8) is 12.f5 Ne5 13.d4 Nc6 14.0-0 Kf8 15.e5 dxe5 16.dxe5 Qe7 17.e6 Be8. I'm never quite sure when to play with the pawns and when to develop.
12...Qf8 13.e5 Kd8
An interesting position! Black's King is temporarily lodged in the middle of his back rank, and his two Rooks are very much parked in the garage. Yet White's lag in development does not (yet) make that situation dangerous. My next move – preferring to open the center instead of reinforcing it with 14.d4 – is a strategic error.

14.exd6
Ask Rybka a simple question and sometimes it will give you a complicated answer. Set this position on "blundercheck" at 5 minutes a move, and Rybka comes up with a line leading to a draw by repetition: 14.d4 Qf5 15.c4 Nh6 16.Nc3 Re8 17.h3 Kc8 18.Bd2 Kb8 19.Rac1 Qh5 20.Qd3 Bf5 21.Qe3 Bd7 22.Qd3 Bf5 23.Qe3 Bd7 24.Qd3 Bf5 25.Qe3 Bd7 26.Qd3 Bf5 27.Qe3 Bd7 28.Qd3 Bf5 29.Qe3...
14...Qxd6 15.Nc3 Nf6 16.d3 Re8 17.Qf2
Sitting here, White's Queen is liable to be harassed by a future ...Ng4. The usual "imbalance" of adventurous connected pawns has disappeared. Black is clearly better.

17...Rf8
Black could have brought some serious heat with 17...Ng4 18.Qd2 Qd4+ 19.Kh1 Bc6. The text move is okay – it's just not best.
18.Be3 b6
Again, 18...Ng4 instead seems the way to go. I was glad to see GabrielChime open up the possible future home of his King.

19.Rae1 Nd5 20.Nxd5 Qxd5 21.Bd2
Trying to get something going.
21...Qxa2
Black feels comfortable enough to grab a pawn, and I was actually glad that he did, as it decentralized his strongest piece. Unfortunately, my response is not best: I should have played 22.Qd4.

22.Bc3 Qd5
Here or on the next move, Black wins the day with ...Rxf4.
23.Bxg7 Re8
I have been handed an even game by my generous opponent. Such is blitz – such is the Jerome Gambit.
24.Rxe8+ Kxe8 25.f5 Ne7
The position is more complicated than it seems at first glance, and Rybka's post mortem analysis leads the game into an oddly balanced endgame where White has a Rook and a pawn for a Knight and a Bishop: 26.c4 Qxd3 27.Re1 Kf7 28.Qh4 Nxf5 29.Qxh7 Rg8 30.Bh6+ Kf6 31.Qxg8 Nxh6 32.Qd8+ Kg6 33.Qxc7 Qd4+ 34.Kh1 Ng4 35.h3 Nf2+ 36.Kh2 Nxh3 37.Qe5 Qxe5+ 38.Rxe5 Nf2 39.Re7 Ng4+ 40.Kg3 Nf6. Needless to say, none of this occurred to me.
26.f6
Play 'em like you got 'em is often good advice for the Jerome Gambiteer, although in this case the advancing f-pawn is nothing special. Unless Black believes it is...
The computer suggests that it is time for the second player to return the extra piece and transition into an even ending: 26...Nf5 27.c4 Qxd3 28.g4 Kf7 29.gxf5 Re8 30.Qh4 Bxf5 31.Qh5+ Bg6 32.Qd5+ Qxd5 33.cxd5 Re2. Perhaps this is chess how it should be played, rather than how I play it.
26...Ng6
Now Black gives his extra piece back (a time-honored defensive move) – only to discover that the resulting position has another piece soon-to-hang.
27.f7+ Kd8 28.f8Q+ Nxf8 29.Qxf8+ Black resigns

After 29...Be8 White will play 30.Rf5 planning to attack the pinned Bishop a second time with 31.Re5. Black can counter this with 30...Qd6 (threatening to exchange Queens) but then White can sidestep with 31.Qg8 with plans to put his Rook on f8, again winning the Bishop. The problem for Black after 29...Be8 30.Rf5 Qd6 31.Qg8 is that there is no way for his Queen to protect the Bishop without coming to grief: 31...Qd7 32.Rd6; 31...Qe7 32.Bf6; or 31...Qe6 32.Qxe6.

Ugandan Chess Master


Every once in a while I have taken a break from posting on the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) to mention happenings in Uganda, where Kennedy Kid Jon spent last summer (see "And Now For Something Completely Different..." and "A Short Break from the Jerome Gambit").

Jon's Uganda blog is at
http://www.jbkuganda.blogspot.com/

Word from the Uganda Chess Federation is that Moses Kawuma, a member of the Ugandan Olympiad Chess Team, recently scored 8-0-2 at the 2008 World Olympiad in Dresden, Germany. According to The Chess Drum, this performance (9/10) was enough for Kawuma to be granted the FIDE Master title.

Here are Master Moses Kawuma's games:

Jerome Gambit: Drilling Down (30)

In the last game in this "human vs computers" Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) match, Yace Paderborn seems headed for the draw that Crafty 19.19 and Hiarcs 8 had found before it, when RevvedUp decides to vary – after all, his position is better.


Unfortunately, that gives the silicon beast the opportunity to lengthen the game and eventually outplay its human opponent.

Yace Paderborn - RevvedUp

Kd6 10.Qd3+

10...Ke7 11.Qg3 Kf7


The draw comes with 11...Kd6, when Yace Paderborn likely would repeat with 12.Qd3+, etc. Perhaps RevvedUp was aware of a couple of previous examples of this line of play – where Black won.

"Objectively" stronger (i.e. a computer thought of it) was 15...Re8 16.Qxg7+ Kd6, but it is not hard to see why RevvedUp preferred the text, even at the cost of an even game.


16.e5 h6 17.Qf4 Re8 18.exf6+ Kf7+
Black's development and relative King safety easily compensates for the lost pawn. But, give White a few more moves to get his position together, and...

19.Kd1 Bxf6 20.Nc3 Kg8


Black has castled-by-hand and retains an edge.

21.Ne4 Rf8

Again, the dynamic aspects of Black's position compensate for the pawn down. Yace Paderborn, however, nibbles away, move-by move.

35.Be3 dxc4


This gives Yace Paderborn a passer, and may not be best.

36.bxc4 Ke6 37.Rb3 Bd4

This exchange opens the floodgates, and White's game improves rapidly. Perhaps something neutral like 37...Bg7 was better.

38.Bxd4 Rxd4 39.Rb6+ Kf5 40.Rxb7 Rd6 41.Rf7+ Kg4 42.Kc3 Kh3 43.f5 gxf5 44.Rxf5 Rh6 45.Rf2 h4 46.d4 Kg4 47.c5 h3 48.d5

Jerome Gambit: Drilling Down (29)



RevvedUp is happy to use the opening innovation in the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) introduced by Shredder 8 in the last game (see "Jerome Gambit: Drilling down (28)") but his hopes for an early draw are dashed, nonetheless.




RevvedUp - Yace Paderbornblitz 2 12, 2006

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+ Kxf7 5.Nxe5+ Nxe5 6.Qh5+ Ke6


7.f4 d6 8.fxe5 dxe5 9.Qe2

9...Nf6 10.Qc4+ Kd6 11.Qd3+

This Queen check, in a position where Black's Knight was not yet developed, led to quick draws in Crafty 19.19 - RevvedUp and Hiarcs 8 - RevvedUp. Unfortunately for White, here the Knight makes a difference.

11...Kc6
Black can go this way, instead of to e2 – but even in that case, White's thematic Qg3 doesn't force a repetition of position: 11...Ke2 12.Qg3 Nxe4 13.Qxe5+ Kf7 14.Rf1+ Bf2+ 15.Rxf2+ 16.Nxf2 and after White captures the Knight at f2 he will be down only the exchange for a pawn, but Black's game will still be much better.

12.Qf3

Fritz 8 prefers the exchange of Queens, but a pawn-for-a-piece is not the ideal Jerome Gambit endgame.

12...Bg4 13.Qb3 Qd4 14.Rf1

A slip, but 14.Qe3 Nxe4 was hardly attractive.

14...Qxe4+ White resigns
