Maybe 6.0-0! is the reason why Rozentalis has been preferring 5.Bd3 Nb4 - ?

Incidentally, when I gave Rybka (1.0) this position, it came out with the weird 6 0-0!?. What's this?, I thought, but soon the idea became clear: 6 ...Bc3 7 ed!. My snap thought was that after 7 ...Bb2 8 Bb2 Qd5 Black should be all right, but I certainly haven't looked at this closely. I hadn't seen this interesting tactic before -- are there any other opening lines in which it occurs?


1.e4 e6 2.d4 d5 3.Nc3 Nc6 4.Nf3 Nf6 5.Bd3 Bb4 6.O-O Bxc3 7.exd5!
What an annoying move!! I think that in your sample variation 7...Bxb2 8.Bxb2 Qxd5 white is just better after 9.c4!
In fact, in all variations I've looked at so far, I like white's chances better  Sad

edit: on reflection, I think best is the simple 7...exd5 8.bxc3 0-0 with a kind of exchange French that should be defendable, even if I don't like it.

For starters, I don't necessarily think that the immediate 6...h6 is best. Watson recommends 6...dxe4 7Bxe4 and only then 7...h6!

He gives a couple of examples continuations, probably the best is the one shown below. Watson quotes this in his Dangerous Weapons book. I think Black is doing fine here.

Wedberg,T (2465) - Kengis,E (2575) [C10]
Haninge Haninge (3), 1992

1.e4 e6 2.d4 d5 3.Nc3 Nc6 4.Nf3 Nf6 5.Bd3 Bb4 6.Bg5 dxe4 7.Bxe4 h6 8.Bxf6 Qxf6 9.0-0 0-0 10.Qd3 Bd7 11.Rad1 Rad8 12.Rfe1 Bd6 13.a3 Rfe8 14.Nb5 a6 15.Nxd6 cxd6 16.c4 b5 17.b3 bxc4 18.bxc4 Rb8 19.Qc3 Rec8 20.Rb1 d5 21.Bd3 dxc4 22.Bxc4 Rxb1 23.Rxb1 Ne7 24.Qd3 a5 25.Ba6 Rd8 26.Qc3 a4 27.Bb7 Nf5 28.h3 Be8 29.Rb4 ½-½

I think White has to push e5 at some stage to get an advantage in this line. Even then, its not clear how great an edge he can get as ...Nc6 constantly attacks the d4 pawn, so White has to tolerate a knight on e4 for several moves.
I've tried the HR a few times on the internet, I think 4e5 is also quite difficult to meet. Maybe its just a case adjusting to a new variation but the typical French moves don't work anymore, instead you need to develop in an entirely different way.

I see what you mean!

Maybe there'll be some more enthusiasm along in a minute. Meanwhile, perhaps I can partly revise my question above on 6 Bg5. Rightly or wrongly, I took it that Black's traditional response of 6 ...h6 is best -- I didn't like the look of the other lines. Now several sources give 7 Bf6 Qf6 8 0-0 Bc3 9 bc 0-0 10 Qe2!? as a bit better for White, usually on the basis of the ancient game Ilyin-Zhenevsky--Nenarokov, Moscow 1924, and I confess I had just assumed this to be correct. But is it? The game continued 10 ...Bd7 11 Nd2, and here Nenarokov's 11 ...Rfd8 looks very odd to me. I showed the position to a couple of engines, which favoured 11 ...Qf4!?, with possible ideas of playing ...f5 or meeting g2--g3 with ...Qd6--Qa3. At any rate the position is very rich and complex, and surely of the "The better/more resourceful player will win" type, so I don't think Black should necessarily be too worried. I wondered, though, if White could go 10 Nd2 immediately, borrowing an idea from a well-known line of Owen's Defence.

Thoughts?  Incidentally, when I gave Rybka (1.0) this position, it came out with the weird 6 0-0!?. What's this?, I thought, but soon the idea became clear: 6 ...Bc3 7 ed!. My snap thought was that after 7 ...Bb2 8 Bb2 Qd5 Black should be all right, but I certainly haven't looked at this closely. I hadn't seen this interesting tactic before -- are there any other opening lines in which it occurs?

I am tempted to start playing the French just so I can play this variation, for obvious reasons.

Funny to see that 3...Nc6 may stand up after 3. Nc3, while after 3. Nd2 it fell victim of the fine Nd2-f1-e3 regrouping Smiley

C10: Hecht-Reefschlager Variation

There have been a few comments on this line (2 d4 d5 3 Nc3 Nc6!?) in the 1 ...Nc6 thread in the Daring Defences section, but I'm not sure there's a separate thread on this interesting line, so I thought I'd start one.

I have a question. How should Black handle the position after 4 Nf3 Nf6 5 Bd3 Bb4 6 Bg5? This looks to me rather awkward for Black, but perhaps I just haven't seen the correct defence yet.
