If so would it be possible to add such a feature to the other >programs? The fundamental difficulty here is that chess engines do not "think" as humans do. Why was the PV selected? The answer seems to be a composite of explainations for: (1) why the search code produced the results that it produced and (2) why the position evaluation code produced the results that it produced. There is more: The full explaination would have to explain the way the search code utilized the results of the position evaluation code and, possibly, visa versa. Explaining "what the computer was thinking" cannot be done in human terms. If you want an explaination in terms of human thinking, you are going to be either disappointed or misled. Bob D.
