For example it is possible that outpost knight bonus does not help the program to play stronger(possible reason is that the program already may evaluate often outposts indirectly by other factors and adding a special bonus may cause it to overestimate knight outpost and play weaker). I wonder if there was a testing of every evaluation term in games and not only testing of the full TogaII when part of the changes may be productive and part may be counter productive. Uri
