I think that it is not so hard to do it. You can change the piece square tables based on the opening and it will only change the level of the program in the opening but will not increase the general level of the program. I believe that you can create a different chessmaster personality for every nunn position and improve the result of chessmaster in the nunn positions. I did not try to do it because it was not important for me(I have nothing to earn by doing it). Some programs today can learn by position(Hiarcs) and you can give them to play nunn position games and learn from them and use the knowledge in future games. I do not say that programmers tune their program for the nunn positions by an opening proccesor or by learning but the point is that I believe that it is possible to do it. I also think that the positions in the nunn match are more tactical and the changes in the evaluation are bigger relative to regular games but I did not investigate it so I am not sure about it. Uri
