Go / Weiqi : Enigma

While looking for other ways to optimize the server, I had an interesting question about Go, that may look more complex than at first sight :)

"Is it possible to repeat a position (at a particular move) without taking a stone or group (at this particular move) ?"

I submitted it in GoDiscussions forum, one member proved it is possible on a 2x2 board... then on 19x19

Okay, harder ! Is it possible to repeat a position at move n without taking a stone or group at move n AND at move n-1 ?

I wonder, would this move n ever be a good move?
