   Thanks for your explanation. Yes, my experiment indicates that the 
playing strengh is almost the same.

   Indeed. My plan is to generalize this scheme with more strict conditions. 
Maybe we even can combine LGRF with the information of RAVE (inspired from 
Arpad Rimmel's works). If the learning works well, it should fix a lot of 
errors in my rules of the playout features. This might be a way to make the 
playouts to learn how to play correct semeai moves.
