Ideal mate
A model mate in which all force take part. [FIDE Album]
The term "ideal mate" was introduced by Eugene Albert in 1963, in Feenschach-Aufsätze. His definition of an ideal mate is as follows: An ideal mate is a model mate in which every White man guards, king and pawns included, and every Black man blocks. For a mate by double check, both checks must be necessary.
