The three-time repetition rule usually involves position rather specific
piece movement. So if the same position, with the same number and type of
pieces, is repeated three times it is considered a draw.
Players need not consider positions before a capture or promotion,
regardless of the particular rules of a variant(such as drops, spawning,
etc.)
And this raises a question: In games with drops, does the pieces in hand
count with the position on the field?
