Not that I'm especially interested in the BDG, but maybe you should ask ArKheiN (if he's still here?) to do the update instead?

Actually, the Counterstrike Variation, 9...c5, against the Zilbermints Gambit in the Euwe Defense, leads to some very interesting tactics. I will post more once I get back from Boston. However, I won quite a few games with White in this line.

Hummmm. Just maybe.

The thing he says about people preemptively dodging main lines into bad systems and getting crushed is also very true however.

Very easy to get a free point in something like the English attack. Don't have a bad game if playing theory either Smiley
(all only true up to a certain level of course.).

I don't agree entirely with Dennis Monokroussos.  The analysis fails to take into account what Tim McGrew calls the "Caltrop Coefficient", i.e. where one side faces somewhat more pitfalls than the other and the payback for one side deviating from correct play is greater than the other.  In many gambits, it is genuinely easier for the defender to go wrong than the attacker at club level.  The question of whether it is better to start with main lines from an early stage depends on whether the player has strong aspirations to become a GM.

Btw I think 1.e4 e5 2.Nf3 f5 deserves "?!", not "??", and I think the same of 1.d4 e5 which is sometimes given a "?".  Both of those openings are often met with harmless replies in OTB games, and lead to an assessment somewhere in the region of += to +/- with best play, not +- as Dennis gives for the Latvian.

An example of an "?" opening is the Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+) which is at least -/+ with best play and probably more.

8.0-0 in the Euwe Defence to the BDG has quite a good caltrop coefficient, better than the Ryder Gambit (5.Qxf3) but I've seen nothing to challenge my view that its objective worth is somewhere between =+ and -/+ after 9...c6 or 9...c5.  I think it probably deserves "?!" as well.

Some interesting comments in that blog, but very little about the BDG.

It didn't occur to you that Monokroussos' comments might apply to your Zilbermints Gambits, including 8.0-0, which you give an underserved exclam?
  

The book had the effect good books usually have: it made the stupids more stupid, the intelligent more intelligent and the other thousands of readers remained unchanged.

Try the Zilbermints Gambit against 7...Nc6 !

I think this provides an excellent answer.

Don't bother to react, LDZ, I already know that you think sceptic and fool are synonyms.

Where have you been? After 1 d4 d5 2 e4 de4 3 Nc3 Nf6 4 f3 ef3 5 Nxf3 e6 6 Bg5 Be7 7 Bd3 Nc6 8 00! Nxd4 9 Kh1 is the Zilbermints Gambit. I assure you, BDGLover, while it is true computers may have all the answers, in a tournament game you cannot use them!
The last tournament game I played, Zilbermints-Tica, 2010, saw White win convincingly. My point is simply that unlike in the Ryder Gambit (5 Qxf3) there are more opportunities for Black to go wrong.

Try the Zilbermints Gambit against 7...Nc6 !

Well, I think that 7...c5 is may be not the best. Literature gives 7...Nc6. Stefan Bücker's Kaissiber 8 gives it and concludes difficulties for Black after 8.a3 and equal but drawish play after 8.Qd2.
So White has to proof that he can develop some initiative after 7...Nc6. That is the test for 7.Bd3.

It is true that 8...Nc6 does not lead to much for White,

That's what I call a convincing answer. Why discuss 7...Nc6 if 7...c5 8.dxc5 Nc6 9.Qd2 leads to an edge for White?

Look, BDGL, I am with many others very grateful for all the lines you provided. Still my instinct tells me that they somehow won't affect the evaluation of 7...Nc6. So you might begin to wonder if your quest is headed into the right direction. Wink

It is true that 8...Nc6 does not lead to much for White, but i still feel that white has an edge in most lines, for example;
1. d4 d5 2. e4 dxe4 3. Nc3 Nf6 4. f3 exf3 5. Nxf3 e6 6.
Bg5 Be7 7. Bd3 c5 8. dxc5 Nc6 9. Qd2 O-O 10. O-O-O Qa5 11. Bxf6 Bxf6 12. Ne4 Qxd2+ 13. Rxd2 e5 14. Re1 Bg4 15. h3 Bxf3 16. Nxf6+ gxf6 17. gxf3 Rfd8 18. Rg2+ Kh8 19. Reg1 Rg8 20. c3 Rxg2 21. Rxg2 Rg8 22. Rxg8+ Kxg8 23. Kd2 h6 24. Ke3 Kf8 25. b4 Ke7 26. Ke4 Nd8 27. f4 exf4 28. Kxf4 Ne6+ 29. Kf5 Ng7+ 30. Kg4 Ke6 31. Bc4+ Ke7  with a winning postion.
One other line might go

1. d4 d5 2. e4 dxe4 3. Nc3 Nf6 4. f3 exf3 5. Nxf3 e6 6.
Bg5 Be7 7. Bd3 c5? 8. dxc5! Nc6! 9. Qd2 Bxc5 0-O-O Be7 11. Bxf6 Bxf6 12. Ne4 e5 13.Nxf6+ Qxf6 14. Rhf1 Qe7 15. Ng5 f6 (15... h6 16. Nxf7 O-O 17. Nxh6+!! and it is all over  gxh6 18. Qxh6 Qg7 19. Bh7+ Kh8 20. Rxf8+ winning) 16. Bxh7 Bg4 17. Bg6+ Kf8 18. Qd5 Rd8 19.Qc4 Rxd1+ 20. Rxd1 Bxd1 21. Ne6+ Kg8 22. Ng5+ Draw.  Black had to play very well to earn the draw. The quest continues Cool

Sorry guys for my last post, bit tried because of work!! Smiley
The line i was talking about was;
1. d4 d5 2. e4 dxe4 3. Nc3 Nf6 4. f3 exf3 5. Nxf3 e6 6.
Bg5 Be7 7. Bd3 c5? 8. dxc5! Nc6 9. Qd2 O-O 10. O-O-O Qa5 11. Bxf6 Bxf6 12. Ne4
Qxd2+ 13. Rxd2 Be7  , with a clean advantage to white.

One other line could go;

1. d4 d5 2. e4 dxe4 3. Nc3 Nf6 4. f3 exf3 5. Nxf3 e6 6.
Bg5 Be7 7. Bd3 c5? 8. dxc5! O-O ! 9. Qe2 Nbd7 10. O-O-O Qa5 11. Bc4 Nxc5 12. Ne5 h6 13. Bd2
Qc7 14. Bf4 Qb6 15. h4 Nfd7  , with equal chances.

One last line might go;

1. d4 d5 2. e4 dxe4 3. Nc3 Nf6 4. f3 exf3 5. Nxf3 e6 6.
Bg5 Be7 7. Bd3 c5? 8. dxc5! Bxc5  9. Qd2 O-O 10. O-O-O Nbd7 11. Kb1! Qa5 12. Qe2 h6 13. Bh4 a6 14. Rhf1 Rd8 15. Ne4 Be7 16. Nxf6+ Bxf6?? this move loses very quickly (16... Nxf6 better, but black still looks bad 17. Ne5 Qc7 18. g4! b5 19. g5 hxg5 20. Bxg5 Bb7 21. Rg1 Rd5 22. Rde1 Rad8 23.  now black gets mashed Nxf7! Rxd3 24. cxd3 Kxf7 25. Qxe6+ Kf8 26. Bh6!! Rd6 27. Bxg7+ Ke8 28. Qe5) 17. Qe4 g6 18.
Bxf6 Nxf6 19. Qf4 Kg7 20. Ne5  and it is all over.

Now as always with analysis, one can find better moves, but i think i have proved that in Tom Pursers BDG pages { article called " hard times"  5 th of April 2010}  7..c5 followed by 8.Qd2 is simply wrong, 8.dc is much better.
I love Toms web site, but on this point i have to say that " Hard Times" ??? I think not. Cool
