What is a "null move"?
Answers are appreciated.
It's one side 'passing' the move. Denoted by --. Needless to say this is not a legal chess manuever but can be useful in software if you need to animate a sequence of moves made by one side.
The null move feature in database programs just means that one side can move repeatedly. It is most often used to illustrate strategies and plans to students.
It's the move the stalemated player makes.
I like Clavier's answer best.
