1.e4 e6 2.d4 d5 3.c4
'passed pawn' The Diemer-Duhm gambit is not just a dumb idea. White gives up
the center pawn in the spirit of the ♗lackmar-Diemer Gambit but at the same
time keeps control of d5 with a pawn at c4. It is not sound enough for regular
use and is not likely to be seen on professional tours, but is a fun opening
for use at the club level. Much of the analysis here is a reaction to the web
page http://www.funet.fi/pub/doc/games/c.... html which is
devoted to the opening. This rare gambit is not even mentioned in ♘CO. %30`2
dxe4 ( 3...dxc4
would be an inferior position for ♗lack from the ♕ueen's Gambit Accepted, cf.
1.d4 d5 2.c4 dxc4 3.e4 where 3...e6 is considered weak. ) 4.Nc3
Nf6 5.f3 ♘ow capturing at f3 leads to positions where White can build a strong attack.
♗lack has a more effective plan, which is to strike quickly at White's central pawn by attacking it from the flank.
c5 This is the ♔eres Variation, and it is the strongest test of White's plan.
6.d5 is the normal move. Supporting the center with 6.♗e3 allows ♗lack the luxury of
capturing at f3, as the bishop is too passively placed. exd5
7.cxd5 exf3 8.Nxf3
In contrast to the ♗lackmar-Diemer Gambit, White suffers from a weak pawn at d5
that will require defense as the game goes on. There is only a little better
development for White to act as  for the pawn. Bd6
! ♗lack is now clearly better. As very little has been published in standard
books, I have looked at the analysis on the web page, and particularly the
suggestions of John Watson, and present the following examples. If the
positions below are not comfortable enough for ♗lack, then 8...a6 comes into
consideration, controlling the important b5-square. 9.Bb5+
( 9.Bd3 O-O 10.O-O Nbd7 11.Bg5 h6 12.Bh4 a6 and ♗lack is ready to launch a queenside attack, while the kingside remains safe, Heikkinen-Anonymous, 1996.
) ( 9.Bc4 O-O 10.O-O Bg4 11.Bg5 h6 12.Bh4 Re8 is Watson's defense, and it is a good one. Again, White has no tangible threats.
) ( 9.Bg5 Nbd7 10.Bb5 O-O transposes to the main line. ) Nbd7
10.O-O O-O 11.Bg5 h6 12.Bh4 'passed pawn' Re8 looks like a strong plan for ♗lack.
( 12...a6 was my previous choice but the situation after 13.Bxd7
Bxd7 14.Ne4 Bf4 is not as good as I thought. 15.Nfd2 is suggested in the Diemer-Duhm online magazine, 1/99.
! ( 15.Bxf6 gxf6 16.Qc2 Re8 17.Nfd2 Be3+ 18.Kh1 f5 and ♗lack has the initiative.
) g5 16.Rxf4 Nxd5 17.Rf2 ! ( 17.Qh5 Nxf4 18.Qxh6 f6 ) gxh4
18.Qh5 and White will be able to attack the weak ♗lack kingside.
Be6 19.Qxh6 Re8 20.Ng5 Qd7 21.Qh7+ Kf8 22.Nxf7 ! earns White the full point.
) 13.Nd2 can now be met by g5 and if 14.Nc4 then ♗lack can either retreat the bishop or play
Bxh2+ 15.Kxh2 gxh4 16.Qf3 Rf8 with an ∞ position, though it can lead to a draw after, say,
17.Qf4 h5 18.Qg5+ Kh7 19.Qf5+ * |

| Sep-23-10 | | rapidcitychess: <Eric Schiller> Yet it is still dubious. |
|
| Feb-14-11 | | Shams: Anyone have a nice "active positional" treatment against the Fort Knox variation? |

| Jun-02-11 | | kellmano: Questionon the french. I hate playing against it as white, so much so that I play the exchange. This can be dull though and I'm getting bored. Is there any way to try to steer it into a completely different type of game? |
|
| Jun-02-11 | | kingfu: Two options:
Tarrasch with the intent of steering the game toward your strengths. KIA with 1. e4 e6 2 d3 with many options including g3 and Bg2. |
|
| Apr-07-12 | | mistreaver: Can some1 say what is the best continuation of line 1e4 e6 2d4 d5 3Nc3 Bb4 4 e5 c5 5.a3 Bxc3 6.bxc3 Ne7 7Qg4 0-0.
I picked up this line in Kasparov's book OMGP,where he gives black's seventh move exclamation mark and says that this is the main line nowadays.
I gave it a try in few internet blitz games, but i couldn't find best replies to 8Bd3 or 8Bg5. In reply to Bd3 i tried c4, when white sacrificed with Bxh7 and got withering attack. Then i switched to Nc6, but didn't like 9Bg5, since this pin is very frustrating (and black can't play f6 and f5).
Any suggestions? |

occurred in the Chessgames challenge the Battle of the Brains II. Team Black replied to 8.Bd3 by playing 8...f5.
You may find very useful analyses there (<acirce>'s summary on page 89 and a lot of material on other pages). Chessgames Challenge: Battle of the Brains II, 2008 |
|
| Apr-07-12 | | mistreaver: <cro77> Ah, thank you so so much, those comments were just what i needed! |
|
| Apr-07-12 | | cro777: In theory the best reply to 8.Bd3 is 8...Nbc6 and if 9.Bg5 then 9...Qa5. The best answer to 8.Bg5?! is 8...Qa5. |
|
| Apr-07-12 | | mistreaver: True, it really looks strong, i guess my internet opponents will have to recon with that surprise, as it is not very obvious move. |

| Sep-23-12 | | kitbitzer31: 1.e4 e6 2.d4 d5 3.Nc3 Bb4 4.e5 c5 5.a3 Ba5 6.b4 (given by Alekhline), why can't Black play 6...cxb4 instead of 6...cxd4 ? 7.Nb5! (again given by Alekhline) 7...bxa3+ 8.Bd2 Bc7 and how has White any compensation for the pawn? I tried 9.Bb4 in several of my games but then Black replied 9...Nc6 10.Bd6 Bxd6 11.Nxd6+ Kf8 12.Rxa3 Ne7 13.Rf3 (in another game, I tried 13.g4!? to prevent the move in the game and Black replied 13..h5)
13...Nf5 and I don't think White has anything. Where did I go wrong? And why is the 6...cxb4 line in the French defense considered weak? Thanks in advance. |
|
| Sep-23-12 | | kitbitzer31: Sorry it is 12...Nge7 not 12...Nce7. Thanks. |
|
| Sep-23-12 | | thomastonk: <kitbitzer31> 8.c3! is the main line. |
|
| Sep-23-12 | | kitbitzer31: Thanks <thomastonk>.... If you don't mind, can I ask you what happens after 8.c3 Bc7 9. Bxa3 Nc6? Once again, thanks for your help. |
|
| Sep-24-12 | | kitbitzer31: Sorry, upon closer investigation,
Maybe 9... Ne7 is better so as to meet 10.Bd6 with 10...Bxd6 11.Nxd6+ Kf8 12.Qf3 with 12... Nf5 |
|
| Sep-24-12 | | thomastonk: <kitbitzer31> White is in no hurry to prove the compensation for the pawn. Black has a long lasting problem with his king. If Black intends 0-0, White can simply develop Nf3, Bd3, and 0-0,
and then launch a king side attack. If Black forces White early to do something with Ba3/Nb5, then he won't be able to castle, and Black is permanently badly coordinated. |
|
| Sep-24-12 | | kitbitzer31: Ah... I see.Thanks. You were very helpful. I remember a quote by Petrosian that went something like this, "Many players after sacrificing a pawn aim not to obtain the initiativefor it but to regain the sacrificed material". It certainly applies here to me. Once again, thank you for your great help.. |
|
| Sep-24-12 | | kitbitzer31: Once again, sorry to bother you but what would you play after 8...Bc7? Any recommendations for White? Thanks. |
|
| Sep-24-12 | | haydn20: <k31> 8....Bc7 9. Bxa3 Nc6 10. Qg4 g6 11. Bd3 followed up by Nf3 0-0 and Nxc7 and White has a blistering attack with an unopposed DSB, while Black is still trying to get developed. 6...cxd4 looks a lot more sensible for Black. Maybe one of the resident stronger players has a deeper view than I. |
|
| Sep-24-12 | | thomastonk: <kitbitzer31> Maybe this opening explorer can answer some of your questions: http://chessok.com/?page_id=352. |
|
| Sep-24-12 | | kitbitzer31: Thanks to both <haydn20> and <thomastonk> in answering my numerous questions. Thanks or being so patient and kind to an amateur. |
