I think this is nonsense. If not knowing which line to search is >tactics, than - per definition - anything is tactics. >Thats silly. >If your definition cannot differenciate between tactics and positional, >than your definition sucks. evaluation function is positional but I think that a computer program with the same evaluation function who knows better which line to search can find that it should not play h6xg5. there are cases when computer program fails in evaluating the position for more than 20 plies(there is no forced variations) and in these cases to avoid the mistake it must have a better evaluation function(knowing what to search will not help practically because if you want to prove by a tree and by the the evaluation function the computer has that the mistake is a mistake then the tree is too large (for example look at the first game kasparov won deeper blue) >>I do not agree we measure how fast their searches are > >And why not ?
