Check with the bishop and restrict escapes with the rook.
The bishop checks along a diagonal while a rook helps prevent the king from escaping. A capture or sacrifice may be needed to open the bishop’s diagonal. Check what the rook controls before committing to that exchange.
Pin the knight to the rook
Your rook lines up the knight and rook. Moving off that line would expose the more valuable piece behind it.
