My favourite answer to the BDG is 1.d4 d5 2.e4 de4 3.Nc3, and just when the BDG player is happy to have sacrificed their pawn, I play 3...c6 or 3...e6. The look on the BDG player's face is priceless! 

The Fort Knox works well against BDG players, since often they get annoyed by Black's rock solid position and make errors in the strategic middlegame.

I just viewed UON 25, and first of all, well done Lev on authoring an opening periodical. Smiley

I didn't look at the periodical closely - I only read the Introduction and skimmed the analysis - but it looks like Lev has done a good job of covering the key games, both old and new, and presented some new analysis that will certainly be of assistance to BDG players.

Whether the analysis stands up to close scrutiny is another question - I haven't studied the analysis because I don't play this variation as White or Black.

Okay, then type Unorthodox Openings Newsletter (UON) and search Internet. It worked for me. I can access it easily.

Well, school has ended and I am hard at work typing up articles on the Zilbermints Gambit. These will be published in a special edition of a chess newsletter. Once the newsletter, which I think will be 100 pages, comes out, you will hear about it.

Rest assured that I make my opinion on chess engine-assisted analyses quite plain. The posts that were posted here much earlier about my Zilbermints Gambit in the Euwe Defense have also been taken into account.

Also, I answer my critics in that newsletter, which you should pick up once it comes out.  

Keep in touch.


That sounds quite interesting.  I hope you'll create this document in magnetic form, so that all of us will be able to share it readily.

Mind you I am going to make it public that from this point I refuse to post to any forum control by Markovich because of his puritanical censorship. If Lev is allowed to nut off then people should be allowed to refute his nonsense, while Markovich is allowed to run riot out of control, I will cease. To me Markovich is feeding Lev's insanity

I was not sure how to reply since anything I say goes off topic.  But I decided that posting here was probably best. 

Gambit is allowed to "nut off" as much as he likes so long as he sticks to the topic, and so are you, and so am I.  Nobody is allowed to post excessively pointed, ad hominem remarks, still less rude ones that contain body references.  These rules, which I would have thought were implicit here, apply to everyone.  I removed an excessively pointed remark of my own, written before I became one of the monitors of this section, on the same day that I removed one of The Hand's.  Is that you?  I am unaware that I have ever edited or deleted one of your posts.

If you would rather not post, that is your choice, but I will regret it because I perceive that you have something to contribute to the discussions here. 

I think I may have missed some bad remarks by Lev and others above; after finishing this post I'm going back and edit them all out -- or delete entire posts if that is necessary.  We're going to have civil conversations here, dear chessfriends, and the subject will be chess.

You send me your email address and I will send you a copy of the 1965 article that Stefan Buecker sent me in 1996. Better yet, why don't you ask Stefan here yourself if he actually sent it to me? That is first.

Second, a full two years before Stefan sent me the article (and I was ignorant of Stadelman at the time), I published my games and analyses in issues 61, 62, 63 of Blackmar-Diemer Gambit World magazine. The editor-in-chief, Tom Purser, is still alive. He can confirm that I sent him the article for publication in late 1993 - early 1994.

NM Alan Watson of Illinois also published an analyses of the Zilbermints Gambit, 3...Nge7, in the November-December issue of Illinois Chess Bulletin. He was the editor-in-chief at the time.

All these publications predate the article that Stefan Buecker sent me by 1-3 years. I had no idea who Samuel Leigh Stadelman was until 1996. By that time, the name "Zilbermints Gambit" was well-established.

The origin of the Zilbermints Gambit lay in the simple fact that I considered the early deployment of the Queen (3...Qe7) risky. I therefore started looking for alternatives to 1 d4 e5 2 de5 Nc6 3 Nf3 Qe7. Thus was born the 3...Nge7 variation, in March 1993.

The first variations I analyzed were 4 Bg5 and 4 b3. It was not until the following year, 1994, that 4 Bf4 was analyzed more in-depth with Edward "Eddie" Kopiecki of New York.

To be fair, I tried locating more details about Samuel Leigh Stadelman, but had little success so far. I know where he lived, where he is buried (Ardmore, PA), but not his death date. Franklin Chess Club merged with Mercantile Chess Club in 1955 to form the present Franklin-Mercantile Chess Club. No one ever heard of Stadelman there, a sad indication that current members do not know the club's history.

More to the point, I cannot locate any games where Stadelman played 3...Nge7. The games that I can locate date to early 1900s, before World War One. In all these games, Stadelman does not play 1 d4 e5.
Thus, I can only surmise that  what Stadelman sent to the Philadelphia Chess Inquirer (where fellow club member Walter Penn Shipley was chess editor) was analyses.  

I hope this answers your questions as to the origin of the Zilbermints Gambit?

In honor of Stadelman, I named the following attack:

1 d4 e5 2 dxe5 Nc6 3 Nf3 Nge7 4 Bg5 h6 5 Bh4 g5 6 Bg3 Nf5

The line 4 Bg5 is known as the Wigglesworth Defense, after the first player to play it. White tries to pin the Ne7, by which he hopes to hold the gambit pawn. Now, the move 6...Nf5 attacks the Bishop and removes one defender. White will get the Bishop pair and get the pawn back.

That said, let me point something out, HTH. I do not agree with Markovich on everything, okay? But this here is a democratic forum, and he is the moderator. As we say in USA, I do not agree with what you are saying, but I will defend your right to say it. Freedom of speech!

You want to have everything your way, HTH? Fine. Then create your own blog, where you can make all the rules. But don't tell me I plagiarized something when I did not. For example, the Rasa-Studier Gambit was independently invented by two players, Rasa and Studier.

Also, show some respect to Markovich. He has a right to express his opinion, the same way as you do.

One more thing: I am quite sane.

Sincerely yours,

Gambit

In the 18...e5 line, perhaps 23...Qh6 is an improvement over Qh5, intending 24.c4 Nf4 where white has to temporarily sacrifice the exchange with 25.Rxf4 Qxf4 26.c5+ Kh8. It looks like white should be on top here with 27.Nf7+, but 27...Rxf7! 28.Qxf7 Be6! 29.Qxe6 Qd2 and again white is grovelling in a pawn-down endgame after all the complications.


Maybe 24.Bb5 Bd7 25.Qc4, for example 25...f5 26.Bxc6 Bxc6 27.Qxc6 Qe6 28.Rxf5 Rxf5 (28...Rfc8? 29.Rexe5) 29.Qxa8+ Rf8 30.Qb7 Nf4 (30...Qxd6 31.Rd1 e4 32.Qxd5+ Qxd5 33.Rxd5 Rf2 34.Rd7 is only a draw) 31.Qc7 Nxh3 32.Qc4 Qxc4 33.Nxc4. The ending is difficult, but White might hold: 33...Rc8 34.b3 Nf2+ 35.Kh2 Ng4+ 36.Kg3 h5 37.a4. 

Quote:
In the line with 14...h6 however, after 15.Ne4 Nxe4 16.Bxe7 I propose the intermezzo 16...Ng3+ 17.hxg3 Kxe7 where the Bxe4 option is unavailable. Howeer here it does appear that 18.Qe5 f6 19.Kc1 Bd7 20.Bf5!! gives white chances, though again perhaps black can navigate.


A nice variation. The software gives 20...exf5 21.Rae1+ Kf7 22.Qxd7+ Kg6 23.Re7 Rhg8 24.Kh2 Rab8 25.Rf4 Qh5+ 26.Kg1 Rbd8 27.g4 Qg5 28.Qxf5+ Qxf5 29.gxf5+ Kg5 30.Rf3 -0.21.

I found a very important game, where both players are Correspondence Chess Senior Masters:

[Event "FICGS__CHESS__CLASS_SM__000002"]
[Site "FICGS"]
[Date "2006.09.01"]
[Round "1"]
[White "Schuster,Peter"]
[Black "de Vassal,Thibault"]
[Result "1/2-1/2"]
[WhiteElo "2488"]
[BlackElo "2425"]

1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 e6 6.Bg5 Be7 7.Bd3 Nc6 8.O-O Nxd4 9.Kh1 c6 10.Nxd4 Qxd4 11.Qe1 Qc5 12.Bf4 O-O 13.a3 Nd5 14.Nxd5 cxd5 15.b4 Qc6 16.c4 dxc4 17.Rc1 e5 18.Bxc4 Be6 19.Bxe6 Qxe6 20.Bxe5 f6 21.Bf4 Qxe1 22.Rfxe1 Rf7 23.Rcd1 a5 24.Bd6 Bxd6 25.Rxd6 axb4 26.axb4 Re7 27.Red1 b5 28.h4 Re4 29.R1d4 Rxd4 30.Rxd4 Ra4 31.h5 Kf7 32.Kg1 g6 33.Rd7+ Ke6 34.Rxh7 gxh5 35.Rxh5 Rxb4 36.Kf2 f5 37.Rh8 Rb2+ 38.Kf3 b4 39.Rb8 Kd5 40.Rb5+ Kc4 41.Rxf5 1/2-1/2

I agree with your analysis on both 12..e5 and 12...Bd7, so 12...Qh5 I will concede to be black's strongest. In the line with 14...h6 however, after 15.Ne4 Nxe4 16.Bxe7 I propose the intermezzo 16...Ng3+ 17.hxg3 Kxe7 where the Bxe4 option is unavailable. Howeer here it does appear that 18.Qe5 f6 19.Kc1 Bd7 20.Bf5!! gives white chances, though again perhaps black can navigate.

Still, I agree with most of your assessments, and feel that 18...e5 still gives white a miserable task in getting a draw. Therefore I think that this is the only try for white (12.Qh4 looks busted) but, if black has done some work, he has absolutely no worries. Of course, OTB both white and black can err, and it's a game of chess.

One of the main points in the BDG is that black shouldn't be hasty to commit his king - the player of the white pieces is usually a knife-weilding maniac [...]


Yes, and by opening all these files he is wheting his knives. The key question is: where will Black's king be safe?

12.Bh4 Qh5

Black intends to castle short, when the queen on h5 is useful, because she protects a few squares. Craig's ideas to castle long seem riskier:

(a) 12...e5 13.Qg3 Be6 14.Bf5! Rd8 (14...0-0-0? 15.Qxg7 attacks f7) 15.Rae1 Rf8 16.Bxe6 fxe6 17.Qxg7 Rg8 18.Ne4, unclear. 

(b) 12...Bd7 13.a3 Qa5 14.Rd1 (14.Qg3 g5!) 14...h6 15.b4 Qxa3 16.Ne4 Qxb4 (16...Qb2 17.Bxf6 gxf6 18.c3 f5 19.Rxf5) 17.Qxb4 Bxb4 18.Bxf6 gxf6 19.Nxf6+ Ke7 20.Nxd7 Kxd7 21.Rxf7+ Kd6 22.Ba6+ Kc5 23.Rxb7 =+. 

13.Qg3 Qg4 14.Qe1 0-0

14...h6 (CraigEvans) 15.Ne4 Nxe4 16.Bxe7 f5 (another nice line is 16...Kxe7 17.Bxe4 threatening Qb4+, Bxc6+) 17.Bxe4 Qxe4 18.Qc3 Kf7 19.Rae1 Qd5 and now 20.b3! has a bit of Sam Lloyd: 20...Qd7 21.Ba3 followed by Bb2. 

15.h3 Qh5 16.Ne4 Nd5 17.Bxe7 Nxe7 18.Nd6

-/+ (SWJediknight) seems fair. However, because of White's activity in practical play Black's task isn't easy: 

(a) 18...Nf5 (CraigEvans) 19.Qe5 Qg5 20.Bxf5 (20.Nxf5 exf5 21.Bc4; 20.Ne4 Qd8 21.Bc4) 20...exf5 21.Rad1 Be6 22.Rd3 or 22.c4, White may survive.

(b) 18...e5 (CraigEvans) 19.Qg3 b6 20.Rae1 f6 21.Be2 Qg6 22.Qb3+ Nd5 23.Bd3 Qh5 24.c4 Ne7 25.c5+ Nd5 26.Bb5 Bd7 27.cxb6 axb6 28.Rc1 cxb5 29.Qxd5+ Kh8 30.Rc7 Rad8 31.Tfc1 =+.
