I've been stubbornly mucking around with the following:

1. e4 c6 2. d4 d5 3. Nc3 dxe4 4. Nxe4 Nf6 5. Nxf6+ gxf6 6. c3 Bf5 7. Nf3 e6 8. g3 h5 9. Bg2 Be4 10. O‑O f5 11. Re1 Be7 12. h4 Nd7 13. Bh3 Bxf3 14. Qxf3 Nf6

Maybe better is to play for 14...c5. I don't love it for Black, who still has some work to do—not least: castling long. But I'm not sure I see what White has either.

For correspondence though what about some return to sanity - the plan of ...Bg7 and ..0-0 is also quite solid I think:

1. e4 c6 2. d4 d5 3. Nc3 dxe4 4. Nxe4 Nf6 5. Nxf6+ gxf6 6. c3 Bf5 7. Nf3 e6 8.g3 Nd7 9. Bg2 Bg7 10. Nh4 Bg6 11. O-O O-O

Black is solid and can look for his chances when White pushes


This looks plausible, but stale. I'd like to think that Black can either liquidate to an endgame with the doubled pawns are actually useful—or exploit the lines against White's kingside to put the king under pressure.

If you go for 6.c3 Bf5 - make sure you are booked up for the dangerous 7.Ne2!?

In general may a development to Bg7  be an interesting thought if you are looking for something "fresh". Reminds me of an old Botvinnik(?) game - although I am not able to find it right now Undecided

I agree - however 7.Bc4! is awkward for black.

6...Qd5 used to be "my" way to counter 6.c3! as black

I wish there was a completely sound response to c3 and I would return to the bronstein/larsen. Lots of good memories...


6.c3 h5 7.Bc4 Nd7 what is the idea for White - you want Qb3 to block in my bishop?


Doesn't 8.Nf3 work? Develop normally? 8...Nb6 9.Bb3 a5 10. a4 or 0-0 both look pretty straightforward. Black's h5 pawn looks a little silly at the moment—and it's going to take some time for Black to be able to mount much along the half-open g-file. Hard not to like White here.


9..a5 looks only weakening
Here I would assume black could try 9..Bg4 and say 10. h3 Bxf3 10. Qxf3 h4!? or e6 / Bd6 / h4 with an ok game

Well, my primary interest is correspondence--avoiding scads of book theory, finding playable positions, and tricking the odd engine into some early misplaced evaluation. What do you think about 9...Qc4 in your line above?

I think you're probably right. As Black, I remain interested in 6.c3 Bf5 7.Nf3 e6 8.g3 h5 9.Bg2 Be4 as perhaps the best h5 advance.


I am also coming to the conclusion the old 6...Bf5 is in fact best.

Currently looking at this endgame:
1. e4 c6 2. d4 d5 3. Nc3 dxe4 4. Nxe4 Nf6 5. Nxf6+ gxf6 6. c3 Bf5 7.Nf3 e6 8. g3 Qd5 9. Bg2 Qe4+ 10. Be3 Qc2 11. Nh4 Qxd1+ 12.
Rxd1 Bg4 13. f3 Bh5

Perhaps White is a bit better but it doesnt seem too much. Enough to handle in a blitz game anyway Smiley

Correct. Qb3 is the obvious threat. With the bishop blocked the black position is not very attractive.

Yes. I was looking at it and I am more worried by 8.Qb3(!) forcing me to lock in my bishop with 8....e6. This seems a little bit too passive for Black for my liking.

Side note to the above. I stumbled upon Nunn-Conquest from Hastings 1996-97 last night. The opening was a Scandinavian, but by move 15 you might be forgiven for thinking this started out as a Caro-Kann in this line. A rather uncomfortable one for Black, mind you. I wonder, though, if some Scandinavian study would be worthwhile...

Nunn-Conquest (Hastings 1996-97)
1. e4 d5 2. exd5 Qxd5 3. Nc3 Qa5 4. d4 Nf6 5. Nf3 c6 6. Bd2 Bf5 7. Bc4 e6 8. Ne4 Qc7 9. Nxf6+ gxf6 10. Qe2 Nd7 11. O-O-O O-O-O 12. Nh4 Bg6 13. Bb3 Bd6 14. g3 Rhe8 15. Rhe1 f5 16. Ng2 Kb8 17. Bf4 f6 18. Bxe6 Nf8 19. Qc4 Bh5 20. Rd3 Nxe6 21. Rxe6 Rxe6 22. Qxe6 Bxf4+ 23. Nxf4 Re8 24. Qxf5 Re1+ 25. Kd2 Rd1+ 26. Kc3 Bg4 27. Qc5 Ra1 28. Re3 Bc8 29. Re7 Qd8 30. Ne6 Bxe6 31. Rxe6 Rxa2 32. Qd6+ 1-0

6...Qd5 & 6...h5 receive coverage in Dangerous Weapons, don't they? Interestingly, Silman doesn't consider either idea in his older book on these lines. My instinct is that Black needs to advance the h-pawn at some point after 6.c3. The question remains when the pawn thrust is safest and best. My gut says that 6...Bf5 ought to be the real test: Black needs to develop this piece as early as possible in order to get the rest of his pieces out in decent order.
