If you turn on the training option before you hit analyse then it does that. Theres 3 options, one is graphical, the other is training and can't remember what the other one was, verbose i think? anyways, you can go through the anaylsis and when u hit the *** part it asks you to guess the move. Like its a quiz and if u guess right then u get points or somehting like that. I didn't like it to much cus it takes forever to go through the analysis so i turned that options off...
