They play well but if weak players are going to ask them for their mistakes the computers may say stupid things. Here is an example from a game between 2 childs under 10 from the other forum [D]8/8/b7/5k2/5p1p/6pP/3B2P1/6K1 w - - 0 64 White played Bxf4 suppose that he later analyzes his game to find his mistakes. every program that I know tells him that Bxf4 was a big mistake when it is a draw after Bxf4 like after other moves that are not Be3.
