In chess parlance, the term model mate refers to a checkmate which is both pure and economical. For example, here is a model mate derived from a 1904 problem by Miroslav Havel:
+---+---+---+---+---+
| |WK | | | |
+---+---+---+---+---+
| | | | | |
+---+---+---+---+---+
| | | |WQ | |
+---+---+---+---+---+
|BP |BK | | | |
+---+---+---+---+---+
| | | | | |
+---+---+---+---+---+
| | |WN | |WN |
+---+---+---+---+---+
Other examples of model mates can be found under
economical mate.
