Programs are not robots and do not move pieces on the chess board. The rules were written only for people who move the chess pieces. When humans operates chess programs in games and the program first make the move on the screen and after it claims a draw the operator can avoid making the move on the board and claim that it is a draw after the move that the program suggest so I see no practical problem. I think that asking programs to use some rules that were written for people who can move the pieces is totally unimportant. Uri
