There is of course some limit, even if it's 1000. If it is 1000 then the question is if it is possible to get a game of 1000 game against the program.

I doubt if humans can play 1000 moves against a program without getting some winning position in the process and without draw by the 50 move rule. A premover can be punished by some stupid sacrifice. I do not think that it is very hard to make a program that detect premovers and punish them by that way. Of course that way have risks but if the program is not deterministic about the time of making the stupid sacrifice the opponent may lose most of the games because he will be unable to guess when the program make the stupid sacrifice and when to stop premoving.
