The Caro-Kann Defence: 1.e4 c6 2.d4... Nd7 arises after 1.e4 c6 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Nd7 and falls under ECO code B17. By choosing the knight over the bishop, Black prepares to exchange White's centralized knight without damaging the pawn structure. Originally associated with the first world champion Wilhelm Steinitz, this line is now more commonly called the Smyslov Variation, after seventh world champion Vasily Smyslov who scored notable successes with it, or the Karpov Variation, since twelfth world champion Anatoly Karpov featured it frequently in his repertoire. The immediate purpose of 4...Nd7 is to simplify the position through an early knight trade while preserving structural soundness. Compared to the Classical Variation, Black gains flexibility by postponing the bishop's development, avoiding the obligation to place it on g6. The trade-off is that White obtains greater freedom to expand in the center, and the aggressive 5.Ng5!? is a frequent choice, raising questions about Black's development tempo and probing the sensitive f7-square. This variation gained additional fame as the setting for the decisive final game of the 1997 Deep Blue-Garry Kasparov rematch, in which Kasparov fell into a known blunder and lost. With 1.8 million Lichess games across all rating levels, it is a well-established opening choice.
