There is no difference between "can" and "must" within a chess engine, for
obvious reasons...

As far as common sense, I have witnessed several examples of where it was not
used in real human tournaments.

But if we reach a position that is a table loss for me in 200 moves, I am _not_
going to refuse to claim the 50 move draw rather than wait for the 200 move
loss.  I don't believe any human would...  So it either becomes a new rule, or
it doesn't.  There is no "gentleman's agreement" for such things in chess that
will work reliably...
