Caro-Kann Defense: Exchange Variation.

Sort:
Shadowking2012

This latest online game I played opened with the Caro-Kann Exchange Variation. I was on the Black side and my opponent was on the White side, and I won this time. As with my previous videos, I would like to know how both sides fared and how the game in general could have been better. However, I'm also curious to know which is generally better in the Exchange Variation; taking with the Queen or with the Pawn; or not taking at all, and why?

Sorry, I meanty previous posts.

Now that you mention it, it does seem roughly like how a Scandinavian defense would be if played out positionally on both sides with solidity in mind. It's also good and interesting to know that the Caro-kann can transpose into a Scandinavian. Thanks.

Take with the pawn! Better to occupy the center, clear space on c6 for your knight if you want, and avoid having your queen kicked around.

I play a lot of Caro-Kann and the exchange variation is problably the easiest situation to be in.

joeooooo, there's a few questions I have for that answer, though. What would happen to the Queen-side in turn? In the very next move, the King's Bishop could slide on over to b5 and pin either the Knight or the rather highly valued (If I'm not mistaken) Queen's Bishop to the King. If it takes the Knight, which is usually the piece moved immediately after the exchange, the b-file is left almost completely open. In my opinion, it's an awkward and tricky position to be in for the first few moves of the game. Have you come across it before? if so, how have you dealt with it in your experiences in the Caro-Kann?

It's ok (good actually) to exchange the queen's bishop if he/she does come in with Bb5. The plan is really to develop naturally on the kingside, get castled, and then deal with the queenside.

My main piece of advice is just to keep things solid, and don't abandon defenses on the kingside!

Shadowking2012

So then it's better to exchange the Queen's Bishop than it is to exchange the Queen's Knight, like I would usually think it is. Also, keeping a solid defense is actually what I tried to do the entire game, but I may well try it via the pawn when I use the Caro-Kann again. And I'll see if I can defend the King-side better as well. Thanks joeooooo.

Black's light square B is often trapped, just like with the French. If you can get it to g4 early pinning white's N to the Q, then keep the pin on until you have to trade, then that's the best. It prevents the N or the Q from getting too frisky early on. Sometimes white castles Qside and you can occasionally get a nice pin on something when you switch the light sq B to the b2-h7 diagonal, but gotta watch the light square B doesn't get trapped if the white Q lays an uncontested (you've moved the e pawn to e6, blocking the return to d7 of the B to block) check from a4 and has a clear line to snap off your B on g4.

For the pawn retake on d5, you are best to take with the pawn, then you get a nice half open c file to get your rook to and the Q doesn't become a target.

His N sac 16.Nxc6 is a bad blunder unless he was already castled and had both Rs in the center, there wasn't any real continuation he would have on you with this sac.

Your long combination starting with 20...Bxg2 then 21...a5 ending at 26...Rxg1 was basically unsound, it would have evened things up except he moved the f pawn letting your Q have great bead on his R at g2, ah, lets say you planned it all along. Wink

Estragon, I take it Qxd5 is more risky because I risk the Queen becoming inactive and being kicked around by the opposing pieces. Or is there more to it?

GreenCastleBlock

...Qxd5 here is incorrect because Black is already committed to ..c6.  White ought to play with Nf3,Be2,O-O, and c2-c4, rather than stick his N out onto c3 right away like he normally does.  In this way White gains a tempo on the Q and sets up a broad pawn center, something White doesn't normally get in the Scandinavian mainlines because his c-pawn is blocked.

Normally Black's best response to this plan is an aggressive setup involving ..Nc6,..Bg4, and ..O-O-O - but Black has already disclosed he is going to play a Caro structure.

Shadowking2012

Bunny_Slippers_, I am aware that my combination was unsound, but I ultimately tried to ready myself for whatever White had in store for me. It just turned out that they in all likelihood unintentionally offered me something more than a solid and equal game.I simply took them up on it. Either way, I DID try to keep ahead in material at least.

Shadowking2012

pfren, please elaborate on why Qxd5 is such a"stupid" move.

Till_98

it might sound hard, but Pfren is completly right. By the way I checked this line last time with my Youth GM Trainer

I diagree with 3... Qxd5. I always take it with the pawn. He can come in with Nc3, you have to withdraw and he wins a tempo. He did have hte upper hand in the opening, he was too passive, that is why the ir turned around...

Shadowking2012
I will not argue nor act condescending as that is not the purpose of these discussions. But there is one question I feel has been left unanswered: How did both players fare in this game?

Pretty exciting game really, lots of threats and some (seemingly) hanging pieces to have to keep track of!

Thanks, Bunny_Slippers_. I'm glad you found the game exciting.
