The Opening Moves

The three moves defining this variation each serve a clear purpose. White's e4 occupies the center while d4 extends this space. Black responds with e6, controlling d5 to prevent White's unopposed advance. Black's d5 then strikes at the center, establishing the tension characteristic of the French Defense. Finally, Nc3 develops the knight while controlling both e4 and d5, the critical central squares.

White's Strategic Goals

White's typical plan is to grab more space by advancing to e5, building a pawn chain that smothers Black's kingside. This same chain supports a natural kingside attack launched with f4-f5. As you build this pawn structure, Black's c8-bishop becomes trapped behind your pawns, unable to defend. This long-term strategic advantage gives you the time needed to mount a decisive attack.

Black's Counter-Siege Strategy

Rather than accept a passive position, Black treats the French as a counter-siege. The initial d5 challenges your e4 pawn, establishing fundamental tension. As play develops, Black uses the c5 and f6 levers to undermine your pawn chain from its base. When the moment comes, the c8-bishop escapes its prison via b6 and Ba6, or it frees itself after f6, joining Black's counterattack.
