Lets understand in detail about this opening and the Doubly Deferred Exchange variation (DERLD) in detail now followed by a popular game played between Anatoly Karpov and Judit Polgar at Linares ESP
Ruy Lopez is a popular opening in chess, also known as the Spanish opening. It is named after a 16th-century Spanish bishop, Ruy Lopez de Segura, who wrote one of the earliest books on chess. The Ruy Lopez is characterized by the moves 1.e4 e5 2.Nf3 Nc6 3.Bb5, where White’s bishop attacks Black’s knight on c6. This move is intended to control the center of the board and develop White’s pieces quickly.
The Exchange variation of the Ruy Lopez occurs when White captures the knight on c6 with their bishop, and Black recaptures with their pawn. This leads to a position where both sides have doubled pawns on the c-file, which can make the position more open and dynamic.
The Doubly Deferred Exchange variation (DERLD) occurs when White delays the capture of the knight on c6 until after Black has played d6 and moved their bishop to e7. The move order for this variation is 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6 dxc6 5.O-O Bd6 6.d4 exd4 7.Qxd4 f6. This variation is intended to take advantage of Black’s pawn structure, which can be weakened by the doubled pawns on the c-file.
