Some programs do not use learning by position so you will get identical games.

I know that some programs do not have important opening knowledge(Junior without
opening book played after 1.e4 e5 2.Nf3 the move d5 against xie when it had not
the opening book and I know that even simple free programs play better without
opening book).

I told the programmer(Amir Ban) about similiar problems when I tested Junior but
he did not fix it.

I believe that Amir could fix it if he thought that it is important.
