I said it before and will continue to say it - expert knwoledge is required to play the Blackmar Diemer successfully. Yesterday I managed to play the line halfways, and, as a result, had to content with a draw.
Guido De Bouver - Stijn Van Vlaenderen
1.d4 Nf6 2.f3 d5 3.e4 dxe4 4.Nc3 exf3 5.Nxf3 Bg4 6.h3 Bh5 7.g4 Bg6 8.Ne5 Nbd7
I believe both e6 and c6 are better
9.Qf3 (diagram)
9...c6 is no good here, as white recaptures the pawn with an advantage : 9...c6 10.Nxg6 hxg6 11.g5 (+=) So my opponent choose the best line.
9...e6 10.Qxb7 Nxe5 11.dxe5 Nd7 12.Bb5 (diagram)
Until this move, i was playing on automatic pilot. But now I starting wondering on how to convert my obvious advantage into a win.
12...Rb8
only move.
13.Qxa7
I was a bit hesitant about this, because I vaguely remembered that black could equalize by removing the pin on knight with a sacrfice 13...Rxb5 14.Nxb5 and black overtakes the initiative ( even if Houdini still gives a white advanatge )
13...Bb4 (diagram)
I remembered a great sacrifice here if black was to play the natural 13...Be7 14.Bxd7 Kxd7 and now the killer move 15.Bg5 (++). but alas, my opponent went for a simple pin on my knight.
Ubntill now, I had been able to play bookmoves - they were lingering somewhere far away, but I was able to retrieve them correctly. But this move got me into thinking.
The correct move is 14.Bxd7 Kxd7 15.Be3 and the black king will have diffciculties to find shelter from the storm. Alas, I played 14.Qa4 and the game ended in a hardfought draw.
Coming back to best line 14.Bxd7 Kxd7 15.Be3 (diagram)
a/ 15...Qh4+ 16.Bf2 Qg5 17.Rd1+ Kc8 18.Qa6+ Rb7 19.0-0 Qxe5 20.Rfe1 Qa5 21.Qc6 (+)
b/ 15...Bxc3+ 16.bxc3 (++)
c/ 15...Bxc2 16.0-0 (++)
d/ 15...Ke8 16.Rd1 Qc8 17.Bg5 (+)
e/ 15...Kc8 16.0-0 (++)
So it is fair to conclude that the above line does not offer any hope for black - a reality check for those that have not yet embraced the joys of the Blackmar Diemer gambit.

The Long Bogo - looking at sidelines
Today we look at an interesting sideline in the Long Bogo : 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 g6 ( the Bogoljubow defense ) 6.Bf4 ( the Long Bogo ) Bg7 7.Qd2 0-0 8.0-0-0 and now the interesting move 8...Nbd7 (diagram)
Scheerer recommends 9.Bh6 Nb6 10.h4 here, but its seems black is better after the obvious 10...Bg4, pausing the white attack before it even started. there must be surely a better way to handle this line. Let's see what happens if black tries to open up the h line, potentially at the cost of another pawn. I guess the most immediate way to do so is 9.h4.
Let's look at a few lines - I will cover today 9....Nh5, in a future post, I will cover some alternatives.
9.h4 Nh5 10.Be2 (diagram)
This looks strange, as black is able to exchange some pieces, but the aim of white is to open the g and h files.
a/ 10...Nxf4 11.Qxf4 (diagram)
...a1/ 11...Nf6 12.Ne5 (=)
...a2/ 11...h5 12.g4 (=)
...a3/ 11...h6 12.Kb1 (=)
...a4/ 11...c5 12.h5 (+=)

c/ 10...c5 11.Bh2 cxd4 12.Nxd4 (=)
d/ 10...Nb6 11.Bh2 (=)
e/ 10...a6 11.Bh6 (=)
So we can conclude that the lin e8...Nbd7 9.h4 Nh5 brings no advantage to black. Maybe there are other black moves that give black some chances, let's discuss that next blog.

If only I could remember
It is now three years and a half that I wrote my blog "Wild, wilder, wildest" on the line 1.d4 Nf6 2.f3 c5 3.d5 e6 4.e4 exd5 5.e5 (diagram)
And last friday, it actually happended - I got this positioning on the board in an offical rated game - if only I could have remembered the correct moves.
Guido De Bouver - Thomas Schurins
1.d4 Nf6 2.f3 c5 3.d5 e6 4.e4 exd5 5.e5 Qe7 6.Qe2 Nh5 ?! (diagram)
Obviously, I had forgotten about the correct move now ( more on that below ), and played for winning the piece 7.g4. This wins a piece for two pawns, but my pawn structure gets suboptimal - to say the least.
7.g4 d6 8.gxh5 dxe5 (diagram)
At this point, I decided to defend my pawns on the h file ar every cost, hoping I could stand his impressive pawn centre.
9.h4 Nc6 10.Be3 Bf5 11.c3 d4 12.Bf2 (diagram)
So far, I have been able to hold on to my defense of the h pawns. But now things get more complicated as my opponent opens up the h file for his rook. Unfortunately, this opens a great diagonal for his black squared bishop.
12...g6 13.hxg6 hxg6 14.Bh3 d3 !! (diagram)
My queen wil get kicked around, so it is back to square zero.
15.Qd1 e4 16.Bxf5 gxf5 17.Qd2 Bh6 18.f4 Ne5 (diagram)
The rest of the game is not of further interest to us, but at this stage, I am still a pieve for two pawns ahead, I have preserved my h pawn, even got rid of the double h pawn. So I achieved what I was hoping for inthe opening, but the price I have to pay for it is quite high as black has a giganic centre with two passers,
In any case, I won the game - in fact, it was my h pawn that I treasured so much, that promoted into a queen. But I can hardly say that I was better in the last diagrammed position.
So dont play this line like this ! The correct move after 1.d4 Nf6 2.f3 c5 3.d5 e6 4.e4 exd5 5.e4 Qe7 6.Qe2 Nh5 is 7.Nc3 (diagram)
Black is completely lost as his queen will get kicked around the battle field, eg 7...Qe6 8.f4 g6 9.f5 !! (diagram)
In my analysis during the game, I had considered 7.Nc3 Qe6 8.f4 g6, but the crushing 9.f5 is hard to see at the board. Black is completely lost in this position, eg
a/ 9...gxf5 10.Qxh5 (++)
b/ 9...Qxf5 10.g4 Qe6 11.gxh5 (++)
c/ 9...Qc6 10.g4 Ng7 11.Bg2 (++)
So continue to read these lines - and remember them !

New stuff on the Vienna defense by Lev Zilbermints
After my earlier blog on the Vienna defense, fellow gambiteer Lev Zilbermints kindly sent me some additional info on the 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 Bf5 5.g4 Bg6 6.h4 h6 line.
I had dismissed this line as unsound, but Lev suggests the straightforward 7.Nh3 (diagram) with some backup lines and games.
I have appended his comments below without modification.
Game 52a: (Moves 1-7 as in game 51) 7 Nh3 c5 8 d5 Qc7 9 Nf4 Bh7 10 g5 Nfd7 11 g6 Bxg6 12 Nb5 Qe5 13 Nxg6 hxg6 14 f4 Qf6 15 Nc7 Kd8 16 Nxa8 e6 17 dxe6 Qxe6 18 Bh3 Qc6 19 00 Be7 20 Be3 Bxh4 21 Qd2 Rf8 ++ - 1-0/35, Zilbermints – “JohnnyBallgame,” ICC 5-minute rated blitz, 6/17/2013.
Game 54b: 1 d4 d5 2 e4 dxe4 3 Nc3 Nf6 4 f3 Bf5 5 g4 Bg6 6 h4 h6 7 Nh3 exf3 8 Qf3 c6 9 Be3?! Bxc2 10 Rh2 Bh7 11 g5 Nd5 12 Bc4 e6 13 Rf2 Bf5, 0-1/50, Zilbermints – “Gateway”, ICC 3 0 rated blitz, 7/26/2013.

My chess practice disagrees with Scheerer’s analyses. After 7…Nc6! the best move for White is 8 Be3 (Games 62 – 63).
Thanks Lev for sharing this with us - impressive stuff - maybe I have to reconsider my opinion on this line.
I had dismissed this line as unsound, but Lev suggests the straightforward 7.Nh3 (diagram) with some backup lines and games.

Harding (1979:90) gives 7 Nh3! ef3 8 Qxf3 Nc6? 9 Bb5 Weissleder-Svensson, as cited in the German magazine Fernschach 1971. Bill Wall (1999:76)
supplies the rest of the game score, stating that it was a 1966 correspondence game. The game concluded 9…e6? 10 Bxc6+
bxc6 11 Qxc6+ Nd7 12 Nf4 Bxc2 13 Nb5

21 gxf6 fxe3 22 Kg2 Bb6 23 Ne7+ Kh8 24 fxg7 Kxg7 25 Kh3 1-0.
In modern times, the
move 7 Nh3 is Gary Lane’s recommendation. He gives the game S. Elgstrand – K. Honfi,
Semi-Final World Correspondence championship 1959 (Game 51). Scheerer (2011:125) gives 7…exf3 8 Qxf3 c6 9 Nf4! Bc2 10 Rh2 Bh7 11 g5 Nd5 12 g6! Bxg6 (not 12…Nxc3? 13 gxf7+! Kxf7 14 Ne6+ Kxe6 15
Bh3+ Kd6 16 Qg3+ and mates) 13 Ncxd5 cxd5 14 Nxg6 fxg6 15 Rf2.
According to Blackmar-Diemer Gambit World #29, December 1987, Karol Honfi Sr. was a Hungarian candidate master who played the Blackmar-Diemer Gambit extensively in the 1950s and 1960s. His son, International Master Karol Honfi Jr., also played the BDG occasionally. The article’s author is Niels Jorge Jensen. He cites the German-language book Gambit Eroffnungen , by Laszlo Alfoldi, as saying that both Honfis promoted the BDG in Hungary. Finally, it must be mentioned that some sources give the date of Game 51 incorrectly. It is 1959, not 1955 or 1950, as some sources have it! Harding gives the 1959 date. Fortunately, I have a photocopy of the Blackmar-Diemer Gambit Volume 2, Number 7, dated July 1963. It was a small newsletter published by Nicholas Kampars between 1962-1967. The date given there is 1959. The German chesslive.de site gives the date 1958. So, which is the correct one? I think that the 1959 date is the accurate one. Diemer’s book was not published until 1957. Thus, few people outside of Germany would have heard of the Blackmar-Diemer Gambit. Indeed, the first BDG in America since Blackmar’s time as Diemer put it, was not played until 1955.

David Robert Lonsdale (2009)
gives the date 1950 for the Elgstrand - Honfi Jr. game. But this cannot be correct, since Gunderam
invented his attack only in 1955/1956.
The earliest publication of the Gunderam Attack is from 1956, in an

It should be noted that after 7 Nh3 e6
there is the premature attacking move 8 g5?!
which I personally would not make. The game Christian Maier – Robert

Let us now see what Scheerer says in his book. After 7 Nh3 Nc6! looks good. Then 8 Bb5 e6 9 Nf4 ( or 9 g5 hxg5 10 hxg5 Bh5!) 9…Qd6 10 fxe4 Bxe4 11 Rg1 000 White had less than nothing for the pawn in K. Boese – A. Kiprov, corr. 1961, Game 59.

My chess practice disagrees with Scheerer’s analyses. After 7…Nc6! the best move for White is 8 Be3 (Games 62 – 63).
