A Closed Game is a particular opening that begins with the moves 1.d4 d5. It is also known as a Double Queen's Pawn Opening or Double Queen's Pawn Game. See also Open Game and Semi-Open Game.

A position where the pawn structure is fixed, the centre cluttered with interlocked pawns. Knights thrive in such positions, and play is generally focussed on the flanks.

A closed game has few open lines (files or diagonals). It is generally characterized by interlocking pawn chains, cramped positions with few opportunities to exchange, and extensive maneuvering behind lines. Such a game may evolve and later become an open game. See also positional play.
