Go up one level in this thread



 I just downloaded your source. I wasn't going to read it, just profile it.
But.......

   A quick look at your search routines indicates you may have a problem with
  number of nodes to complete a ply.
     -- You don't use fractional extensions. All your extensions are full.
     Going to fractional extensions could help considerably.

   In your qsearch, there is something that at first look seems to be a bug.
   You check the futility of the move before checking to see if it is a legal
   move. Seems incorrect to me, but I was doing a quick scan.

   I'll try profiling it now. Will post the results here.
