ducks on the button... what's your play?

[JPaps18]

Late in a $20 MTT on Stars. 31 left of 954, 81 paid so already into the money. Next bump is at 27 from $76 to $104. Average is ~35k, i forget exactly, so I'm a little below it. I have gotten AQ twice in the last orbit pushed and got no callers. I have also used position to pick up a few blinds and bb is aware of this(he has played back at me)I am dealt 22 on the button and everyone folds to me. How would you go about playing a small pp in this position with all relative information? Limp? Raise? All-in? Fold?

Since I had pushed twice and hadn't showed down I decided to just raise and see what happened. Even if the raise was wrong in the first place, what do you do once you're reraised all-in against a bb you know is able to make a play back at you? Is 18k enough to fold and make an attempt to win at this blind level (1500/3000)? Or did I commit myself with my original raise?

Small PP's late in tournaments seem to be a big leak for me so any general comments on playing small PP's or specific comments on the hand itself are welcome. Thanks, JPaps18.
