Was there ever any conclusion on 1.e4 e6 2.d4 d5 3.Nc3 Nc6 4.Nf3 Nf6 5.Bd3 Bb4 6.0-0!? Bxc3 7.exd5! Nxd4 8.dxe6!? which seemed both critical and unclear in the previous thread?


My conclusion then was that Matemax's maniac's choice provides excellent winning chances. To quote the post:

I was just thinking about the beginning of the variation and thought that the maniacs choice could also be
8.de6!?


some lines  Cool:

8.dxe6 Nxf3+ 9.Qxf3 Be5 (9. ... Ba5 10.exf7+ Kf8 11.Bc4;  9. ... Bd4 10.exf7+ Kxf7 11.Bc4+ Kf8 12.Bg5) 10.exf7+ Kxf7 (10. ... Kf8 11.Bg5 (11.Be3 Qd5) 11. ... Be6 12.Rfe1 Qd6 13.Rad1) 11.Bc4+ Kf8 12.Be3 Bd6 (12. ... Qd6 (a strange comp-line coming up...)  13.Rad1 Bxh2+ 14.Kh1 Qb4 15.Rd8+ Ke7 16.Rxh8 Bg4 17.Bc5+ Qxc5 18.Re1+ Kd7 19.Be6+ Bxe6 20.Rxa8 Bd6 21.Kg1) 13.Rfe1 Bd7 14.Qxb7 Rb8 15.Qxa7 Rxb2 16.Rad1 with good compensation!

so perhaps black has to turn to:
8. ... Nxe6 9.bxc3 O-O
or  8. ... Bxe6 9.bxc3 Nxf3+ 10.Qxf3 Qd5 11.Qg3 O-O-O (11. ... O-O 12.c4 Qc6 13.Bb2 Bd7 14.Rad1)
which is certainly better for white

well let me hear from you  Smiley


The more I look at it, the more I like it!  Smiley
After 1.e4 e6 2.d4 d5 3.Nc3 Nc6 4.Nf3 Nf6 5.Bd3 Bb4 6.O-O Bxc3 7.exd5 Nxd4
8.dxe6 Nxf3 9.Qxf3 Be5 10.exf7 Kxf7 11.Bc4 Kf8
I think 12.Re1!? might also work!
for example
(a) 12...Qd6 13.Bg5 Qc5 (13...Bxh2 14.Kh1 Bg4 15.Qxf6!) 14.b4! Qxc4 15.Rxe5
(b) 12...Qd4 13.b3! Qd6 14.Bb2 Bxb2 15.Rad1 Bd4 16.c3
(c) 12...Bd6 13.Be3 transposes to your analysis, but 13.Bf4!? also looks strong.
This all looks excellent for white. What do you think?

Interesting - so 6.0-0 is a Rybka suggestion - this is probably how GM Nijboer found it also!

6.0-0 was already discussed in the forum 2 years ago.  Wink

Another example of grandmaster practice finally catching up with forum analysis!  Cheesy

Karpov-Agdestein was cited in ECO as slightly better for White.

There's also 6. e5 and then Bg5, as a young Austrian grandmaster played recently.

6.0-0! certainly looks strong.

Watson recommends 5.. Nb4.

Interestingly, Agdestein even beat Karpov with black in that variation.

53.Qf8+ Kh7 54.Qf5+ Kg8 55.d5 Qc2 56.Qf3 b2 57.d6 b1=Q 58.d7
Qbd1 59.Qa8+ Kh7 0-1


(Watson gives 6... Nxd3! 7. Qxd3 dxe4 8. Nxe4 Be7 as a "clean approach").

Thanks again to Kevin for one more interesting Hecht Reefschlager update. However, one of his comments made me curious....

"After 1.e4 e6 2.d4 d5 3.Nc3 Nc6 4.Nf3 Nf6 5.Bd3 Bb4, White normally plays 6.e5. In the game Nijboer-Reinderman, White played the outrageous 6.0-0!: The idea of this move is shown after 6...Bxc3 7.exd5 and no matter how Black chooses to win a pawn, White will nick the 2 bishops plus a huge initiative to boot. I'm not sure if this idea will refute the entire variation for good but it certainly looks like a very good try. At least, all subscribers are aware of it now."

And following at the end of the game
"I seriously think this new idea can be a serious blow to the Hecht-Reefschlager and unless I find something convincing, I guess it would be a while before I play the Hecht again. For now, good news for White exponents!"

However, after 6.Bd3 black doesn't need to play 6...Bb4. I think black can play 6...Nb4 winning the Bishop pair and having a decnet game. Right?...or I am missing something.
