Hiarcs7.32 is a good blitz program and I do not think that slower time control will help hiarcs(the opposite they help Fritz because Hiarcs has a bug at longer time control). I have not Fritz6a but my gues is that Hiarcs is not smarter than Fritz. I think people look at the number of nodes per second to decide which program is smarter and I guess that it is a wrong decision. It is possible to change the number of nodes per second by a different definition of the term nodes but the program will not be better. programmers mean to different things when they say nodes(for example in Rebel nodes are only legal moves when in most programs it is lso some illegal moves.
