Subject: So how do we tell when to avoid null-move?

Go up one level in this thread


This and the many other null-move-killer positions regularly posted here seem to
show that crafty's simplistic check (avoid null move when side to move has only
one non-queen piece) could stand some improvement.  What better algorithms are
other programs using to tell when a position might be zugzwang?  I vaguely
remember a commercial programmer (Christophe or Ed?) making a cryptic comment
about double-null-move solving this problem, but I didn't understand what that
might mean.
