The best thing you can do to get close to the real tournament is to run Shredder 7.04 under UCI and with tournament book option on. This will not be the same as in tournaments the book selection has not so many alternatives. The commercial version needs to have many alternatives not to be boring as it is made for the users to get fun with it. This means that you cannot create exactly the same, but it could be similar. Also here you are running a version which is about one year old, since the new Shredder 8 will be available soon, while Crafty is with the latest version and may include also some lines specifically prepared against Shredder 7.04. This needs to be taken into consideration as well. About Crafty ask Robert. Sandro >> >>My advice is to run crafty on both machines, and compare the NPS.
