>>I implore you to re-read my post(and pay attention this time). I never suggested the possibility of some "gestalt" configuration setting for all positions. I was talking about SPECIFIC modifications to the default that would be beneficial for SPECIFIC types of positions. I will provide a very simple example(that even you should be able to grasp). When you are looking for a line in which white has a forced win, you are not going to want to do branching for both black and white(tying up processor time on unnecessary white alternative lines). You will want to set branching for black only. Understand now?

Yes, I understand that you are rude and not worthy of my help.
