Subject: Root Move Ordering

Author: David Rasmussen

Many people use node count (or time) to order root nodes, apart from always
ordering the pv move of last ply first, of course. This seem to work ok. But as
some people have suggested (Christophe, for one), this method isn't very much to
the point and might have unwanted sideeffects.

On the other hand, we can't very well order the moves by score since (at least
with PVS) we don't know the exact score of any moves but the pv move. So what
method is "best"? And what method do top programs use? How is it done in Fritz
or Tiger?
