It's not a repeated "move", it is a repeated position.  When a position
has been repeated three times, the game can be declared a draw by
repetition.

with a fairly recent FIDE change, it works like this, to the best of my
knowledge.  If, when it is your move, and you can show that the current
board position has been repeated three times, you can claim a draw.
Also,
if you can show that after you play move "X" the position has been
repeated
three times, you can claim a draw by making the move and claiming the
draw
before pressing your clock.  Note that this is *not* mandatory however,
you
can play through a three-fold repetition by making a different move,
even though the original position was repeated three times, assuming
your
opponent didn't claim the draw...

the 50 move rule is the same...  WRT being "optional"...
