Facing a constant mini-raiser in level 4 or 5 from the BB

[45suited]

I will preface this by saying that I am very happy with my results. With over 1000 SNGs at the 11s, my ITM is around 44% and my ROI is about 36% and both numbers have been going up steadily. My numbers (with less games) at the 22s are similar.

I have a question and I'd like to know if this is a leak in my game or just solid play. Here's the situation:

Say the game is down to 6 handed. You're in level 4 with a decent stack (say 1000-1600). You notice that the guy two spots to your left is constantly mini-raising to t200. (He might have even started doing this on level 3.) The other players keep calling and getting outplayed after the flop. Just bleeding chips. Well, in levels 3 and 4, you're chip position is healthy, but it's not enough that you really want to get into a pissing contest with mediocre cards. But obviously the mini-raiser has picked up on this and keeps mini-raising your blind.

Currently, I don't really try to get fancy and play back at a guy like this. I wait. I fold and maintain my stack. I allow the other guys to get bled and bide my time. Or eventually someone picks up a hand and plays back at him and he is dumb enough to call (without proper pot odds) with some weak junk. I get into the money with this patient strategy and if I do pick up a hand, I'm not calling the mini-raiser, I'm popping him in the mouth.

My question is: Am I just playing smart or weak? I mean, as much as I know the guy doesn't have a hand every time, if my position is healthy, I'm just not one to play back at the guy for all my chips with a 9Jo or whatever when I can just lay back and be the initial raiser myself.

Maybe this is the difference between the 11s and 22s and you guys who play the 109s and 215s? At my level, I can just wait for the other guy to screw up. At your level, you probably don't have that luxury.

Anyway, that's my question: Is my play smart or is it weak? My results tell me it is smart, but at the table I feel like a wuss sometimes as I allow the mini-raiser to run me over.
