SB v BB: facing mini raise from chipleader

[45suited]

Villain had been using his chip lead well. Raising lots of pots, never laying off my blind. How big of a hand do you have to have to play back at him, given the relative chip positions at the table? If I fold, I'm down to t590 after posting the SB next hand, probably facing a button raise from chipleader again. Is pushing here (knowing that you'll be called) reckless? Or is this as good a spot as any to take a stand and get back in the game? Usually I'm patient and avoid raised pots, but if you pretty well know that he's doing this (and will continue doing this) 3 out of 4 hands???
