Tap a piece, then tap a highlighted square to move it.
Queen's Gambit
White offers the c-pawn to pull Black's d-pawn away from the center, aiming for faster development and central control.
Key ideas
• It isn't a real gambit — White usually regains the pawn.
• Declining with e6 or c6 is the most common and solid reply.
• Accepting with dxc4 gives Black a temporary pawn but concedes the center.
What to play next
e6
Queen's Gambit Declined: solid, keeps the center, prepares to develop the bishop.
c6
Slav Defense: defends d5 with a pawn, keeps the light-squared bishop free.
dxc4
Queen's Gambit Accepted: grabs the pawn, plans to return it later for active piece play.
