a3 Bxc5 b4 is an idea which gains spaceon the Queenside and allows Bb2, protecting that advanced central pawn. If black plays a5 b5 is a good space for a knight. Follow this with castling and c4 at some point, attacking black’s supposedly solid structure.
Caro-Kann Defense: Advance Variation, Botvinnik-Carls Defense


The Caro-Kann is my favorite as Black, but I am also giving white players some advice. Against the Botvinnik-Carls you are supposed to play c3, not dxc5, though it is still playable.

Terrible advice.
Quite the contrary, do not play c3, because black could play an improve french advance variation with Bc8 ready to pin Nf3 or to go to f5.
Of course, dxc5 is the move (or even c4), when black's task is not so easy, with play like given above by chess_cat_1000.
The idea is to keep e5, not d4, when e5 is a kind of spine in black's side.
Of course, c3 is playable, but can lead to disaster like this :

I like to play Caro-Cann defence!
I wish more people were like you! I love destroying the Caro-Kann so much that I fantasize about it! 3.f3 baby!

3.exd5 is a joke!
3...exd5 and Black has fully equalized already:
4.Nf3 (4.Nc3 Bb4) Nf6 5.Bd3 Bd6 6.O-O O-O 7.Bg5 Bg4 8.Nbd2 Nbd7 9.c3 c6 10.Qc2 Qc7 11.Rae1 (11.Rfe1 Rfe8=) Rfe8= 12.h3?! Bh5 =/+
Your comment is a joke too! No originality in your statement, and 3.f3 in the Caro-Kann is called the Fantasy Variation. There is no fantasy about 3.exd5 in the French, just stupidity!

Well, black still has to deal with the Monte Carlo variation which as a french player have found it to be difficult to deal with.

If you are referring to 3.exd5 exd5 4.c4, it's not difficult. 4...Nf6 and if 5.Nc3, then 5...Bb4. Same rules apply here as do the Queen's Gambit Declined. Don't take on c4 until the Bishop has moved.
The position is not as dull, but just as equal, as the symmetrical line.

Hi all.
I seem to keep losing games as white in this opening. What systems is good for white and what are the developing ideas before the middlegame for white after dxc5`?
Thank You.
It would be helpful to see some games, or at least the openings, to get a better idea why you are losing. It may not be the opening, or it may be that the positions you are getting do not suit your style, or you just lose tactically later. I would also like to see how black is playing it.
