none really that i know of. of course there are two, but those are obvious, the
first is easy, the second is hard: get the defending king to the edge of the
board, and if possible, separate king and rook of the defender. but it's tough
to win this on knowldege, i would say - humans at least can hardly win against a
computer defence, and they are nice examples of chess-playing entities not
searching very deeply :-)
