As far as I can see, the Ziegler Defense with Bg6 is better for Black.

And that makes me realize I wrote the last line erroneously !
Please read 14...dxe4 15.c4 (Teyko's proposal) 15...Nf5!

After 3 days this is all you come up with ?
Isn't it a sign that there is something wrong with the wariation ?
Well, I would not mind playing this "absolutely equal" variation with Black...but did you check 14...Nxe4 15.Nxe4 fxe4 16.Bg5 Be7 17.Bxe7 Qxe7 18. Qxe4 Rf8 19.0-0-0 Qg5+ 20.Kb1 Rf2, or 18.0-0-0 Qg5+ 19.Kb1 e3?

Chiefly, after 15...dxe4 16.Qe2 Nf5! you, Teyko, the fierce attacking player, which side would you rather be, honestly, a real chessboard with that position under the eyes, if you were not a 'til death BDG defender' ?

Bonsai,

I wdid not mean to implicate you by the post, I am merely arguing that the complications of the Blackmar Diemar should be met with an understanding and certain graciousness that other openings are met with. 

I was on the King's Indian thread and there is an argument to be made that the same thing happens in the Bayonet attack that happens in the Hubsch gambit. Same is true for the Alapin Sicilian, the Dragon, the Ruy Lopez, and the King's gambit, yet strong players still play and advocate these other systems. 

The Blackmar Diemar gambit is meeting the challenge that the forum has raised and I think that in the most critical lines White is getting a draw and if Black plays anything but the Hubsch or the Bogo then White is better. 

I will analyze the line introduced in the exchange variation of the Zeigler, but in most of the main lines, white is better. 

I appreciate the opinions of the forum, and as I said I take what GM Prie says based on his authority as a grandmaster, but I believe that it is the purpose of the forum and the practicioners of this system to question the assumptions of that authority and see if anything is workable. 

I am not asking for an emotional or sympathetic ear, merely a critical and objective view of this system.

Thank you for your attention,

Tommy J. Curry

While I understand the issues that people have with the Blackmar Diemar Gambit, I don't understand the rudeness and maliciousness that individual's seem to be meeting my analysis or opinion with.

Fine White is equal in some of the critical lines, namely the Bogolibuv and Hubsch lines that GM Prie advocates, but how is this any different than the main lines of the Ruy Lopez, or the C3 sicilian that white plays to defuse the Sicilian. I fail to understand why equality in the Blackmar Diemar in two main defenses equals absurdity. 

In every case, the Blackmar Diemar Gambiter's have made an attempt to supply analysis and Over The Board analysis of the positions, where as the critics merely turn on fritz and look at its first evaluations. 

From experience, I can tell you it take Shredder and Fritz 8 on 256 MB a while to come up with an accurate evaluation of the position.

Thank you for replying G.M. Prie,

I just wanted to say I appreciate your feedback, being that you are a grandmaster and all. 

I don't know how to post diagrams on the forum boards, but I will send you all of my analysis to your email account. 

I have found that black has to play almost perfectly to hold the endgame position and want you to look at this analysis if you don't mind in a possible update. 

Again thank you for your time, and I hope that this can prove worthy in my attempts to show the serious viability of the Blackmar Diemar gambit.

Gentlemen,

An answer to the Hubsch Gambit, by Tommy J. Curry.


  1.d4  Nf6  2. Nc3  d5  3. e4 Nxe4 4. Nxe4 dxe4  5.Bc4 Nc6 6.c3 e5 7.d5 Ne7 8.f3 Nf5 Grand master Prie's move! 9. Bb5+ Bd7 10.Bxd7 Qxd7 11.fxe4 Nd6 12.Nf3! I think this gives white something to work with in this variation. 

12...f6 seems interesting, but after 13. Nd2 Be7 14. c4 or 14. Qh5 with the idea of 15. Qe2 doesn't look to threatening.

12...0-0-0 13. Nd2 Qb5 14.Qe2 Qxe2+ 15.Kxe2 f5 16. b3!?(Shredder found this) fxe4 17.c4 and I believe white equalizes from this point on. 

I have analyzed 17...g6 and 17...Nf5 and found equality.
