No, doesn't work for me, neither the Czech nor the English version. And I've tried two computers, both with IE.
  

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.

Hmm, it works for me using IE.  But the copy and paste is buggy.  Perhaps try his home page and see if you can get in from there:   

http://www.mujweb.cz/www/rajmunde/index.htm ; (Czech version)

Thank you very much.

I wonder why some people still can access the site and some cannot...

Ok now, from my personnal point of view, I don't know if 8.Nf3 is the best, but 8.Qe2 is quite interesting too, it has been the choice of Leisebein but I think it's really one of the very best line for Black, I used and would use it again myself against the BDG, so the choice between 8.Nf3 or 8.Qe2 may be important for White.

Why?

Are you writing another book?

I haven't been able to reach the site for a year or two, so I'm afraid the site is down indeed. But if you're interested, I have saved a summary of the Alkhemy Variation.


I am interested in anything anyone might have saved from the site. I would really appreciate that!

Patrik, I'll have to look through the analysis on Rajmund's page.  It is very dense!

Update:  I found the analysis on the website after 1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 c6 5.Bc4 Bf5, which is under the heading "without exf3."  

6.dxe4 Nxe4 7.Nxe4 is their recommendation for white.  


I'd like to see this analysis as well, but I simply can't reach the site - all I get is a timeout every time I try to access it. Is the site down? And if not, is there any other way to reach the material from it?

No matter what fanatics like LDZ say. Not playing a variation, because some people will think you are a coward, is one of the worst reasons I have ever heard. If you like the b7-b5-b4 idea as Black and feel comfortable with it, then play it.

I think black may have a slight edge due to white's static weaknesses; however, at worst the game is in a middlegame with dynamic equality where the better player has good chances to play for a win.  I think I would rather play positions like this in a tournament, instead of trying to find a refutation in a more standard line in which a BDG expert would be more well versed.  And if I were to win, I guess being called a "yellow coward" would be something I would have to face.   But that's a risk I am willing to take.  Smiley

On side note, I think I may have found a middlegame in a critical line of the Alchemy variation with the material imbalance queen vs. rook, knight, and two pawns, where black seems to have good chances to play for a win.  Of course, this position needs to examined more carefully but I think black has good long term chances if he has a good plan.  The play seems to be more of a positional, maneuvering game which I don't think the average BDG player would feel comfortable with.  Weaker players seem to handle material imbalances like this badly, especially the side with the queen, when there is not a clear plan.  I have seen a master player simply outmaneuver a class A player after he dropped a queen for two bishops and a pawn.

1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Bc4 Nf6 5.f3 b5 6.Bb3 e6 7.Bg5 Be7 8.fxe4 b4 9.Bxf6 Bxf6 10.Nce2 Bb7
I am not going to claim an advantage for White. But I do not see, why he should be worse either. I actually do not understand the similarities with the c3-Sicilian. In that opening I have never seen an half open f-file for White. For the time being I do not see Black simplifying to an advantegeous endgame.
10...Bh4+ 11.g3 Be7 12.Nf3 o-o 13.o-o is about equal.

11.Nf3 o-o 12.o-o c5 13.e5
Indeed 13.dxc5 and 13.d5 are inferior, but what about 13.Qd3 maintaining the centre? After cxd4 14.e5 Be7 15.Nexd4 White is not worse. Sure Black has a pair of bishops, but White's knights are well placed. 13... Nd7 probably transposes.

13.... Bf6-e7;14.c2-c3,
It is not clear, if this is necessary. 14.Qd3 Nd7 15.Qe3 with about equality.

14.....,Nb8-d7;
14... bxc3 15.bxc3 cxd4 16.Nexd4 as White must activate pieces. The justification is Qc7 17.Bc2 Qxc3 18.Bxh7+. Black has other options of course.

15.c3xb4,
15.Qd3 Nb6 and Black controls d5.

15.....,c5xd4;
15.... cxb4 16.d5 Qb6+ 17.Kh1 exd5 18.Bxd5 Bxd5 19.Qxd5 Rad8 20.Nfd4 with interesting play.

16.Qd1xd4,
16.Nexd4 Bxf3 17.Qxf3 Nxe5 18.Qe4 Bf6 is not entirely clear either

16.... Qd8-b6;
16.... Bxf3 17.gxf3 Qb6 18.Qxb6 axb6 19.f4 Bxb4 20.a3 is about equal.

17.Qd4xb6,a7xb6;18.Ne2-d4,
White threatens 19.Nxe6 and is not worse again.
I agree that Black has chances too. Well, White's gambit is not that good after all. So my verdict is, that the prepared Black player certainly can play these lines - if he is not too optimistic. White should not care too much about his weak pawns, but look for active piece play.

<What gambiteers fear most of all is not being feared.>
Wrong. As a lifelong gambiteer - though not of the limited and fanatic kind as described by Yermolinsky - I can assure you, that positions in which long, patient manoeuvring is requiered, are feared more. But what we gambiteers fear most, are dull draws as so often occur in the main lines of the Petrov, with its incredible high drawing rate at top level.
