The Queen's Gambit is a popular chess opening that begins with the moves 1.d4 d5 2.c4. In this strategy, White offers a pawn on the c-file to gain control of the center of the board. If Black accepts the gambit by capturing the pawn, White aims to develop pieces quickly and create strong attacking chances. This opening is named after the queen piece, which plays a crucial role in the strategy. The Queen's Gambit can lead to various game types, including the Queen's Gambit Accepted and the Queen's Gambit Declined, each with its own tactical ideas and plans.
