Nevertheless, I would also fear some risks and would be already happy when the machine would first learn from finished games and the analysis of finished games (wich also includes a lot of search trees) and modifies the evaluation just on the basis of the current position and the experiences made before the current game. Learning from the searchtree in a completely new position might make sense ofcourse when there are some reliable evaluation results. Ofcourse the machine could also adapt the evaluation on the basis of some features of the searchtree, as the chances for the opoonent to make mistakes or the number of features occure in parts of the search tree don't fit to the abilities of the opponet, ... I just would claim the machine not to change everything in evaluation just on basis of the search tree. If the machine calculates to long within search space it might occur that it throws away everything it ever learned about chess before, claiming "now I got the real view onto chess and chess strategies, I stop trusting all the old masters from now on, I don't trust my trainer anymore, I don't trust my programmer anymore, it's me that has the only right and ultimative view onto chess, don't stop me now... I am just reinventing chess..." Such appearance of chess machine insane might be a very interesting experience of computer conscience (?)... but I would prefer happening it under control and not in a tournament... Although, it might make computer chess a record breaking TV attraction... Internette Gruesse, Ingo
