Move Ordering

• Add an extensive move ordering algorithm to the root moves.
  • Does not matter how expensive this is, since it will not be done much, compared to to the millions of ordinary nodes.

• Break out after the 1st or 2nd ply from the AlphaBeta search and take top few candidates?

• Do a Quiescence search on all moves and order by the values it returns.
  • Bring the PV move up front if not there already.
  • Count the nodes each move causes and order by that.
  • Try various combinations (Quiescence score with some scale for lower plies, and node counts deeper depths).
