Queens Gambit Declined Orthodox Defense Skewer in Chess

In the Queens Gambit Declined Orthodox Defense, the “Queens Gambit Declined Orthodox Defense Skewer” is a tactical motif where a piece is lined up so that one target must move, exposing a more valuable piece behind it. A defining feature is the central/queenside structure after moves like 1.d4 d5 2.c4 e6 3.Nf3 Nf6 4.Nc3 Be7, where pieces on the same file or diagonal can be pinned in a skewer arrangement. The skewer typically uses a queen, rook, or bishop to force the front piece to move, revealing a higher-value piece (often the king or queen) to capture.
