Opera Mate Beginner Chess Puzzles

Opera mate beginner refers to the famous mating pattern where a rook delivers check on the back rank while the enemy king is trapped by its own pieces. The classic version is associated with the Morphy Opera Game, where the key idea is a rook on the open file supported by a bishop or queen, and the king has no escape squares. For an intermediate player, it is a simple but elegant example of coordinating pieces to exploit a cramped king.
