I meant to Mike and not to Bob hyatt. Positional knowledge is important when both sides are good in tactics but in the case of Mike it seems to me that the main problem of the program is tactics. I am not against improving the evaluation function but my opinion is that most of the efforts of Mike adams should be to improve the tactical ability of his program if the target is to do his program better.
