Advanced Strategies in Caro-Kann: Deep Dive into the Exchange Variation - Part 2 (4. Bd3)

The Caro-kann is arguably the most solid choice for black. Black comfortably completes the opening and enjoys a good middlegame as both white and black have chances to explore. This is the Second part of the Caro-kann opening series where we will discuss the Caro-kann Exchange variation in depth, 4. Bd3 to be specific.. In the last post, we discussed the Panov Attack. Please check the post if you haven't checked already.

The caro-kann starts with 1. e4 c6 and from then on there are many variations, The move sequence for the Caro-kann exchange variation is 2. d4 d5 4. exd5. White exchanges the pawn in the center and hence the name is known as Exchange variation. Black completes the exchange and the below position appears on the board



Caro-kann Exchange variation begins

In this part of the Caro-kann deep dive series, we will discuss move, 4. Bd3 which can be played by White in this position.


4. Bd3

The main idea is to counter the very basic strategy of caro-kann which is to develop, the light square bishop. White takes control of f5 and g4 square, making it difficult for black to develop the light square bishop.

Black continues development with Knight to c6, Below is the move sequence


4. Nc6 5. c3 5.. e5 6. dxe5 6.. Nxe5 

Position after 6..Nxe5


In this position, White mainly plays Qe2, pinning the knight to the king. Below is the move Sequence

7. Qe2 7.. Qe7 8. Bb5+ 8.. Bd7


Black Offers an Exchange of Bishop

White has a choice to make, it can either capture the bishop or it can continue development with Bf4 Increasing pressure on the knight. Analysis of this position on higher depths shows that black is better by just meniscus (-0.13). All black has to do is to develop its pieces as soon as possible to castle. 

One surprising move order could be as below

9. Bf4 9.. O-O-O 


Black long castles

White has no way to attack the king right away. It's a provoking move, if white takes the bait and starts moving its pieces to attack the black king, black will have ample time to develop its pieces.

White should exchange the light square bishop here, black will recapture the bishop with its knight, offering an exchange of queen. This shows an easy path for black to develop fast.


Black's e5 move almost forces white to exchange pawns in the center and black ends up putting the knight in the center. The Variation, that we should take a look at is 7. Nf3 instead of 7. Qe2

White will rarely play into it as Black will capture the bishop and will continue its development. 

The move sequence is as below

7. Nf3 7.. Nxd3+ 8. Qxd3 8.. Nf6 9. O-O 9.. Bd6 10. Bg5 10.. O-O 11. Bxf6 11.. Qxf6 12. Qxd5 12.. Rd8 13. Qg5 13.. Qxg5 14. Nxg5 14.. b5

The resultant position will be equal.

In the next post, we will look into variation 4.Nf3 of the Caro-kann exchange variation.
