1. e4 e6
1. e4Stakes a claim in the centre, controlling d5, and frees the bishop and queen.
1... e6Supports the centre, adding control of d5. Theory calls this the French Defense.
An early pawn trade leaves the c-file as Black's avenue and the d-file as White's - both sides get real winning chances down their own file. Black keeps the extra pawn; White plays for time, open lines, and initiative - the classic gambit trade. e5 gains space and shuts in Black's king's bishop.
2. d4Stakes a claim in the centre, controlling e5, and frees the bishop and queen.
2... d5Stakes a claim in the centre, controlling e4, and frees the bishop and queen.
e5 gains space and shuts in Black's king's bishop; the whole game revolves around the d4 point - Black piles on it with ...c5 and ...Nc6; White defends it with c3.
The pawns on d5 and e4 stand in direct tension - the first player to resolve it chooses the structure. Nd2 sidesteps the Winawer pin and keeps the pawn front intact: White accepts a modest centre in exchange for a sound, theory-light edge.
...e6 and ...d5 build a pawn wall that concedes space but never weakness: Black hits the white centre with ...c5 and later ...f6 while the light-squared bishop waits for its moment.
