I use min-raises against good and aggressive players as bluffs when the pot has already grown big. Here's an example from tonight:
Party Poker No-Limit Hold'em, $ BB (6 max, 3 handed)

<font color="#C00000">saw showdown</font>
Button ($399.10)
Hero ($400)
BB ($1208.15)
Preflop: Hero is SB with J[img]/images/graemlins/spade.gif[/img], A[img]/images/graemlins/spade.gif[/img]. Hero posts a blind of $2.
<font color="#666666">
1 fold</font>, <font color="#CC3333">Hero (poster) raises to $10</font>, <font color="#CC3333">BB raises to $36</font>, Hero calls $28.
Flop: ($80) K[img]/images/graemlins/spade.gif[/img], 3[img]/images/graemlins/diamond.gif[/img], 5[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players)</font>
Hero checks, <font color="#CC3333">BB bets $69</font>, <font color="#CC3333">Hero raises to $150</font>, BB folds.
Final Pot: $299
Villains 3-bet handrange against me is much wider than {AA-QQ, AK} and he has made close to pot sized continuation bets every time he has raised.
