With a "couple" of beta testers, the thing will go into a "deep think" that is _far_ longer than the time one would expect for a move. IE it moves consistently at 30-50 seconds per move, then takes 10 minutes. In a position where it did _not_ fail low. I believe that the operator simply wants to give it a chance to find something that may (or may not) be there. It is my opinion, with no proof of course. But it is _very_ common with _all_ engines. ChessPartner makes it trivial for the operator to influence things. I can do it with xboard if I thought that I somehow might know more about when to spent more time than Crafty does... As far as proof, simply play a few fully automatic games at (say) 30 30 or whatever time control you like, and then check the times. See if you see any case where it takes more than 10x the normal time per move, when the score did _not_ drop _or_ rise during that search. If you find such cases, I will certainly retract my statement. But in watching so many games of late, it is obvious that something goes on "from time to time". IE I see most programs taking 2x-3x on fail lows. And sometimes for other reasons. But not 10x or longer. IE I would certainly like to do the same if that is the way games are to be played. When I say Crafty is "automatic" I mean _automatic". It does _everything_ by itself, completely.
