What is a opera mate?
Named after Morphy’s famous opera-house game: a rook (or queen) mates along the back rank or central file while a bishop pins or covers the diagonal escape.
How to spot it
A bishop slicing toward the king’s escape diagonal plus a heavy piece owning the open file — when both lines meet at the king, the mate is there.
What this set trains
A pattern that teaches piece harmony: two long-range pieces covering complementary lines.
