Are there any examples of high-level games in which the game was resigned or drawn without any captures? Are there examples of high-level games which were resigned or drawn before any captures were made?  Along similar lines, what game had the most moves before a capture was made?

Edit: I'm especially interested in longer games without captures (I'd like to see the strategies, etc); I'm not necessarily looking for the shortest game without captures.
Wikipedia says that the longest decisive game without a capture is:

Nuber-Keckeisen, Mengen 1994 lasted 31 moves without a single capture. In the end Keckeisen, facing imminent checkmate, resigned:

For a drawn game:

Filipowicz-Smederevac, Polanica Zdroj 1966 was drawn in 70 moves under the fifty-move rule, without any piece or pawn having been captured (Whyld 1986, p. 124).
