For the Caro-Kann Powerbook an Elo average of at least 2375 was set. Thus 58 000 games from Mega and from correspondence chess met the threshold for the Powerbook, to which were added 736 000 games from the engine room of playchess.com. The Caro-Kann is considered a safe opening, since it is very rare for Black to have to put up with a compromised pawn structure. Nowadays there is quite a different way of playing the Caro-Kann. This is also reflected in the Powerbook. After 1.e4 c6 2.d4 d5 the main continuation is no longer 3.Nc3 dxe4, but quite clearly 3.e5 Bf5 4.Nf3 – with statistics based on more than 175 000 games. The amount of theory has grown enormously and the Powerbook offers several interesting approaches in the search for promising side variations. An especially popular one is in the Two Knights Variation 2.Nf3 d5 3.Nc3, but also in the Exchange Variation 2.d4 d5 3.exd5 cxd5 4.Bd3 there has been a surprising renaissance in recent years.
After the most frequently played moves 3.e5 Bf5 4.Nf3 e6 5.Be2 Nd7 6.0-0 Black has a wide choice although some moves lead to the same position with different move orders. Probably the critical move is 6...Ne7 and it appears that the Powerbook continues by a wide margin with 7.c3, whereas in human chess the c-pawn move has no great part to play (with first 6...h6 the same is true for 7.c3). After 7...h6 8.Nbd2
We still have in the Powerbook more than 44 000 games, the online database having only 480, with very few of these games by the world’s top players, and those all in blitz or rapid chess. Moreover the statistics are not bad for White – a good opportunity for you to get ahead of the competition.
