Now markovich has to choose between 9..Nd5 ; 9..Nfd7 ; 9..Bh5 ; 9..Nh5 ; 9..Ng8 and 9..Qxd4?!
It would take a lot of place to put all my analysis against every Black's response but I will try to put somes analysis tomorow. This is quite a difficult path because the way of playing is very different in each move and it's hard to say wich line is really the best. 
Actually Im practicaly prepared to every Black's response but I have to choose the most accurate response to 9..Nh5!? but I have some ideas about the way of playing it for white here.

1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 Bf5 6.Ne5 e6 7.g4 Bg6 8. Qf3 Nd5 

A) 9.Bb5+ c6 10.O-O Nf6 11.Be3 cxb5 12.Qxb7 Nbd7 13.Nxb5 Rc8 14.Nc6 Rxc6 15.Qxc6 Qb6 16.Qc8+ Qd8 17.Qc6=

B) 9. Bd3!? Qh4+ (9... Nc6 10. Bb5 Qh4+ 11.Kf1!? or Kd1 with transposition) 10.Kd1 Nc6 11. Bb5 (11.Nxd5 exd5 12. Re1 O-O-O 13. Bf5+ Kb8 14. Nxc6+ bxc6 15. Qb3+ Ka8 16. Qa4=) 11... O-O-O 12.Bxc6 bxc6 13.Nxc6 Rd6 14. Nxa7+ Kb8 15. Nab5 unclear. Shredder gives small advantage to black. It is strange as white is a pawn up. Fritz evaluates this as =. It needs to be checked in more depth. But I somehow feel it is not the right way.

1.d4 d5  2. e4 dxe4  3. Nc3 Nf6  4. f3 exf3  5. Nxf3 Bf5  6. Ne5 e6 7.g4 Bg6 8.Qf3 c6 9.g5

8..c6 is logical, solid and the main move.
But I have some times ago analysed 8..Nd5!?gaining time over c6 in some variations and add the possibility of Qh4 wich really deserve attention to me, if I was Black I would surely try it to play for a win wich is a bit unexplored. Here can follow 9.Bb5+(Practicaly forced to me, Black being very good against any other response, and Bb5+ is profiting that c6 has not been played to gain a tempo to castle with attack on f7)..c6 10.0-0 Nf6! and here, 2 choice for White : 11.Be3 or 11.Rf2 where this move was assessed like a good move after ..cxb5 12.Qxb7 Nbd7 13.Nxb5 Rc8 14.Nc6 Rxc6 15.Qxc6 etc with a good play for White but I found that 14..Nc5!!leading to a forceful and advantageous play for BLack after 15.Nxd8 Nxb7 16.Nxb6 Ne4 17.Re2 Rb8 18.Rxe4 Rxb7 19.Nc3 Bxe4 20.Nxe4 =/+ at minimal
So 11.Be3 is maybe the best and need deep analysis.

8..Nbd7  is quite interesting after 9.Nxg6 hxg6 10.g5, but it's a rare move that I have not seriously analysed yet, but at first sight it doesnt'seem specialy promising for Black.

1.d4 d5  2. e4 dxe4  3. Nc3 Nf6  4. f3 exf3  5. Nxf3 Bf5  6. Ne5 e6 7.g4 Bg6 8.Qf3


Still a classical way of playing from White and Black here.
The main alternative is 8.Bg2 but I think it's just a question of taste, and I have more experience with 8.Qf3 but I know that Patrik Schoupal for example would surely play 8.Bg2 with a chance for an advantage, but I let it for a future Patrik-Markovich match maybe?

Markovich has surely choosen most solid move.

Just to give what I think about 7. Black's other response : After the sacrifices : 7..Ne4 8.gxf5 and white have surely an advantage, for example ..Qh4 9.Ke2 Qf2 10.Kd3 Nc5 11.Kc4 a6 12.a3!!

7..Nfd7 8.gxf5 Qh4 9.Ke2 Nxe5 10.dxe5 Qg4 11.Kd3 Qxf5 12.Kd2 Be7 13.Qe1 Nc6 14.Bd3 0-0-0 and is about unclear but I would not play it with Black.
7..Bxc2 8.Qxc2 Qxd4 9.Qe2 Bd6 10.Nf3!
7..Be4 is playable, but against 8.Nxe4 Nxe4 9.Qf3 (Qd3!? - P. Schoupal) there is no better than draw for Black.

1.d4 d5  2. e4 dxe4  3. Nc3 Nf6  4. f3 exf3  5. Nxf3 Bf5  6. Ne5 e6 7.g4 Bg6

In the spirit of the Search for Truth, I would request that anyone wishing to contribute to White's or Black's cause do so with public analyses posted here.  That will be much more informative, and a lot more fun!   

They say that in these days there are no more chess principles, only the specifics of given positions.  Unfortunately my knowledge of chess is so limited that I almost always do rely on general principles!  Here I prefer to play a simple move, rather than seek complications in a position where I am a pawn up with no weaknesses.   Let the burden of proof remain with White.  Also subjectively, 7...Be4 and 7...Ne4 just do not look like good chess to me.

White compromises his kingside pawn structure with 7. g4, but he risks little since, with his pawn-minus, the ending is bad for him anyway.   In the mean time, my bishop is active on g6.   

Some years ago I confronted Chuck Diebert over-the-board in this position and the game continued 8. g5? Ne4  9. Nxg6 Nxc3  10. bxc3 hxg6.  With two sets of minor pieces exchanged, White had even less compensation than normal.  I continued to play well, but I used up a fair amount of time and eventually, with about two minutes still showing on my old Jerger and just two moves to make the time control, my flag fell!  I was two pawns up by then, but Diebert, who is an excellent tactician, had stirred up plenty of trouble. 

Lev I have read your posts and given you the benefit of the doubt as far as your intentions in advancing the Blackmar Diemar Gambit, but this is ridiculous. 

For those of us who are actually trying to find the most correct moves and contribute to theory this is the most appropriate way to do so. 

Charles Diebert for example as been more than interested in my findings (he will know me as Tommy J. Curry) even though they were computer checked. 

Dude no one here is interested in the fact of whether or not you can win a blitz game; we are interested in knowing whether the Blackmar Diemar Gambit can be played at higher levels.

One of the ideas of these games, Teyko, is to allow anyone kibitzing and send in his comments!
I find it a pity, that you have not commented (yet?) my game against Patrik.
