Tap a piece, then tap a highlighted square to move it.
French Defense
Black prepares d5 to challenge the center while keeping the position solid, at the cost of temporarily boxing in the light-squared bishop.
Key ideas
• e6 supports a d5 push next move without weakening the kingside.
• Black's light-squared bishop is often hard to develop — a well-known trade-off of this opening.
• Typically leads to closed, strategic positions with pawn chains locking in the center.
What to play next
d4
Grabs the center immediately; Black replies d5 and the main tension begins.
Nc3
Develops first, keeping options open for d4 or an early Nf3 setup.
