The Caro-Kann Defence arises after the moves 1 e4 c6. With this first move Black (as is also the case with the French Defence - 1 e4 e6) plans 2 ... d5, establishing a well-protected central pawn. The Caro-Kann has a reputation as a rock solid defence that minimises the risk of Black being subjected to undue early pressure. Rather than inviting the opponent to engage in immediate warfare, Black focuses on completing development comfortably and postponng the serious battle until the middlegame. It is notable that the White systems which try to batter the Caro-Kann into early submission are highly double-edged and often rebound badly.

White players who enjoy playing the Ruy Lopez (1 e4 e5 2 Nf3 Nc6 3 Bb5) often expect to have an easy time in the opening. Numerous Black systems allow White to complete development with natural moves which often results in a small but clear advantage. Not so The Schliemann. 

Starting a chess game with 1 e4 e5 is so common that the resulting complex of opening systems traditionally commands its own sobriquet, “The Open Games” (1 e4 met by other replies are “Semi-Open Games” and everything else comes under “Closed Games”). The central structure with pawns on e4 and e5 often leads to play based around highly classical themes which are the bedrock of successful chess understanding.
