For a long time the caro-kann has been my default opening against e4, but I fear I may need to give it up. Here's why:

As you can see it is quite potent. I have as yet not found a refutation for it, so I was wondering if anyone else had come across it, and how the game went. I've only been able to find a handful of games online, and none played by good players.

However, if you do come across it, here's how I recomend playing. I Think it is sufficient to allow Black to survive.

i am a caro- kan player my self and i think that the only way for white to get an edge against it is nc3...in this positiion  the wrong move is the one you are sure off in your comments...

so i will let it to you as a puzzle and tommorow when i wake up and have time i will check your answer and tell you some basic points on how to get better with black in this position..and i mean it better...see you tommorow

i dont understand why 9...Bxf3 when 0-0 seems more logical, although in all fairness there may be long term reprecartions with a 9...0-0. but still....

ok here comes the answer...

Go to the above site.  There are 24 games from your initial position (8.O-O) dating from 1963 through 2000.  Score for the 24 games is 8-6-11.  Just from that I don't see this as a big threat to your favorite.  Take a look at all of the games.

good..

Don't know why this was lost but the site is www.chesslive.de

After c3 I usually play e5. Had some interesting games with it!

No need for White to go into the Exchange variation proper anymore now that 2. Nf3 d5  3. exd5 cxd5 4. Ne5 has gotten traction.
