Ouch...

I only can search to 4 ply in that position in 60 sec and my null move succeeds
about 40% of the time.  I believe this bad performance has sometime to do with
my qeval routine and the fact that it considers all captures/promotes.  I think
I need to be more selective about captures in the qeval routine.  My program
plays f2f3 after 1 minute of thought.  Here's the report (if anyone cares):

  total nodes.....................................4588297
  time (sec)......................................60.71
  rate (nodes/sec)................................75579

  null move successes.............................73
  null move failures..............................117
  null move success rate..........................38.42%

  pawn hash hits..................................4469147
  pawn hash misses................................117413
  pawn hash success rate..........................97.44%
