Class 2 - Class 3

There are two types of Class 3 problems which can end in a stalemate. In one, the stalemate is an avenue which the blocked position might terminate, by one side happening to lose all its mobile pieces except for the king, and then having the king blockaded.

More interesting from a taxonomic perspective are the cases where some play might blow the position wide open, except that to do so involves a stalemate, which happens to end the game immediately.
