Please let me clear this issue a little more. a) SSDF testing is not made by the programmers so they couldn't tune his programs according to every new opponent. b)Being so, if, let us say, anyway F6 is delivered to the swedish people after being tuned against Tiger 12, my question is, what would happen to F6 against other programs? Why tunning against program X neccesarily means the likelihood to get more points in a pool constituted by many opponents different to X? c) That is the core of my question and the only way I found to understand your point is to suppose that Tiger 12 brings not only some specific features that could be anulated so and so, but general, universal improvements so if you tune againts them, you improve your own program "in general" d) In this way, tunning againts Tiger 12 would means tunning against any other program. e) If that is not the case, I still believe that in a tournament where you face many different opponents, just to prepare againts one of them could means a worst general result, at least you can do the same thing before every game, but we already know you cannot do. Sorry is this seems a little bit confused. It is :-) Fernando
