Go up one level in this thread



  At one time, I had captures as part of history and killer moves.
  It worked well. At that time, I did nothing else to sort move ordering
  other than pv first.

    Later I modified my move ordering to consider captures first. At that
  time, it was more effective to drop captures from history and killer
  moves.

     IIRC, the two methodologies were just as effective in quiet positions
   on 9 ply and less searches.
