Is the king lacking mobility on some side?  In this case its by the knight and rook (blue squares).

Can you provide a diagonal line of fire?  Yes bishop on f5.  This is suppression fire as it is keeping the king from escaping.

In this case the queen was sacrificed to open up a diagonal vulnerability.

Now it's ready for the black bishop to deliver the mate.|5,4,1,0,yellow|
