Inspired by P1182074

White releases stalemate as a #2, giving Black 20(!) moves. First record in a new task. See:
http://matplus.net/start.php?px=1606065655&app=forum&act=posts&fid=gen&tid=2586&pid=20040#n20040
Henrik Juel: No record, P1182074 is far better in terms of giving Black moves, 32
But this problem also a #2 (2020-11-22)
A.Buchanan: First record in a new task (2020-11-22)
James Malcom: Henrik, you misunderstood! The task is different from the 32! This is about Black release in the #2 form, not releae in the fairy form. (2020-11-22)
