I believe that not the human operator but the program should decide on whether
to accept a draw or not. After all, offering draws and accepting them is part of
the game.

Another thing to be considered is that both Fritz and Piket play way better
chess than Mr. Morsch. So what if the position would have been won but he didn't
realize it ( and Fritz hadn't shown it because it was too far away ) ?

Most Computer programs have a so called contemptfactor meaning that for example
if they are down -0.15 but the contemptfactor is set to -0.20 they will not give
a check by repetition if possible. Against a strong human like Piket the
contemptfactor could be positive. Now when the human offers a draw the operator
would simply click on the "draw" button in the interface and in case 0 > eval -
contempt the computer will accept, else decline.
