Some caro kann questions

Can someone look at my game, and tell which moves I should have played better in the opening? Because I just took a guess at some points and I want to get a higher rating with the caro-Kann 

4 Bxd3 loses development when he takes back and develops Q

e6 instead

15. double your rooks

I am playing black. Also, thanks everyone for the responses! Keep 'em coming!:]

I agree with Rainbowrising. You missed nothing, the alternatives such as playing ...a5 earlier are just a matter of taste.

Black!? I'll just delete my post and go stand in the corner for a while :)

Thanks for posting this. I have just started looking at the Caro-Kann mainly to get blacks Queen Bishop into play. Just as you did. Keep at it.

Yeah, the opening was good -- the point that Bxd3 is fine is you're removing your "bad" bishop for his "good" one.  Your pawns will be on light his on dark.  Your remaining bishop complements your pawns, his does not.  It's a very logical trade easily worth a tempo -- and actually white usually kicks it around even more (h4, g4 stuff) before playing Bd3 and it's even good for black to trade then, so yeah, it's obviously a good move to trade.

on your 6th move, i have seen variations where black plays Qb6, then Qa6 looking to exchange queens.  if white doesn't exchange, then white has a hard time castling for a while.  black can then push c5.  just be careful because there are a few traps with it, but it is a playable line.

Yes, I have had this idea played against me many times at my club, finally found out trading queens was bad if you can avoid it, Nf3 early to 0-0 or avoid the trade and play Ne2 so that you can 0-0 is what I do as white.

Your opponent obviously didnt know the opening very well, he should have waited to play Bd3 (if at all)until after you had commited to 4...Qb6. 4.Nc3 is much more flexible. Bah.... its hard to tell from this game where to improve your opening because white  played the opening terribly, but thats just my opinion. There was a famous game with Nimzowitsch vs Capablanca that shows some of the themes in this line well, but that game also has alot of opening mistakes you dont see much anymore. That being said, understanding the typical manoeuvres in the middle game and the type of exchanges and endgames they engender is what is really important in this opening. I think Seirawan, and Kotronias have written some interesting analysis about the advance variation (3.e5) of the Caro-Kahn that you might want to find.
