封闭性开局，又名“双后前兵开局”，以1.d4 d5开始。因为此类开局容易封锁中心区域，故名。

以前把双后前兵开局（1.d4 d5）、印度防御（1.d4 Nf6 2.c4）以及任何不以1.e4 e5开始的开局都称为封闭性开局。现代国际象棋理论书籍则把除了双后前兵开局的其他开局从封闭性开局中分出来，另外分类。这里取这样的分类法，以符合潮流。

常见的封闭性开局有：

A Closed Game (or Double Queen's Pawn Opening) is a chess opening that begins with the moves:

The move 1.d4 offers the same benefits to development and center control as does 1.e4, but unlike with the King Pawn openings where the e4 pawn is undefended after the first move, the d4 pawn is protected by White's queen. This slight difference has a tremendous effect on the opening. For instance, whereas the King's Gambit is rarely played today at the highest levels of chess, the Queen's Gambit remains popular at all levels of play. Also, compared with the King Pawn openings, transpositions between variations are more common and important in the closed games.
