The Caro-Kann Defense: Exchange Variation arises after 1.e4 c6 2.d4 d5 3.exd5 cxd5 and falls under ECO code B13. In practice, this position almost invariably transitions into the Panov-Botvinnik Attack via 4. c4, unless White opts for the quieter 4. Bd3. The seemingly natural 4. Nc3?! is considered inaccurate because the knight accomplishes little on that square: occupying e4 would be premature, and after ...e6 the d5 pawn becomes firmly entrenched. Playing c4 first, followed by Nc3, is far more effective since it creates genuine pressure against d5. With 25.3 million Lichess games across all rating levels, it is a well-established opening choice.
