I think that ScubaChuck is right on with his 4 reasons why guys mini-bet. If I see a guy do it more than once or twice, I've started doing something like this (PP 22, blinds 25-50)

UTG ( $1950 )
UTG+1( $1120 )
CO ( $390 )
Button ( $1280 )
SB (HERO) ( $1590 ) dealt 8sJs
BB ( $1670 )

UTG, CO, Button, HERO all call. BB checks.

** Dealing Flop ** [ 2s, 6c, 9d ] (Pot t250)

HERO checks.
BB checks.
UTG bets [50].
CO folds.
Button folds.
HERO calls [50].
BB folds.

** Dealing Turn ** [ 4c ] (Pot 350)
HERO bets [250].
UTG folds.

I don't do this often, but in this case, I had the benefit of knowing that there was a good chance that I could get the pot heads up. It was also a benefit that I was OOP. Plus, villain had mini-bet twice before.
