This is in reply to Teyko from the "Why is the BDG so misunderstood?" thread. I refer to Teyko's lines in this thread and in the given web page above (
http://www.mujweb.cz/www/rajmunde/ec_ena_alch.htm).
He thinks the ziegler is good for White. I think not.
1.d4 Nf6 2.Nc3 d5 3.e4 dxe4 4.f3 exf3 5.Nxf3 c6 6.Bc4
6...Bf5 7.0-0 e6 8. Ng5 (the so-called alchemy variation)
8... Bg6 9. Ne2 (the brilliant idea is to maneuver to play Nf4 so as to sac on e6.. very cute indeed and might well catch alot of people out).
But Teyko (and the website) fail to deal with 9... c5!. This is a most classical and natural move. When White has moved his pieces away from the centre (look at the knights on g5 and e2!), Black strikes at the centre.
The most principled reply imho seems to be 10. Bb5+.
But that's nothing after 10... Nc6. Against 11. Nf3, 11. c3 and 11. Be3 Black replies to all with 11... Qb6!
If 11. Bxc6 bxc6 12. c3 Qb6! followed by Rd8 against just about every sensible move -+.
If White does not play 10. Bb5+,
Nc6/Qb6/Rd8/cxd4/Bc5 are all possible moves in one order or another. e.g. 10. c3 Nc6!
And if White tries something funny after 9... c5 like sacrificing on e6 it's simply not enough with only the bishop on c4 and Knight on g5 (why else would he bother to maneuver the knight to f4 in the first place). I am not going to post meaningless analysis. (just use fritz).
The best way to counter this sort of gambit is to stick to classical chess principles. When your opponent attacks you at the side bash him in the centre! It may be a dogmatic, stodgy and old fashioned view of chess but this is the way to go against gambit crazed attackers.
