Subject: Null Move and Schizophrenia

Author: Pat King

Before implementing null move, I had a simple aspirated AB search, and would
research with a window of (Beta, Infinity) for fail highs and (-Inifinity Alpha)
for fail lows. And life was good. With null move, however, it's not uncommon for
my program to get stuck, alternately failing high and low, without ever properly
resolving the score. What's up with that? Must the research be done
(-Infinity Infinity)? Or is this a sign that I've a bug in the null move code?
