Ruy Lopez Bird Variation Discovered Check Chess Puzzles

In the Ruy Lopez Bird Variation, the key idea is that a bishop move can uncover a check from a rook, queen, or bishop by vacating a line. This discovered check usually appears after White has developed along the Ruy Lopez structure and Black’s king is still vulnerable on the back rank or central files. For an intermediate player, the defining feature is not the opening move itself, but the moment one piece moves away and reveals a direct check from another piece.
