Preflop: Hero is MP2 with 8:d 8:c
MP1 folds, Hero raises to $0.08, 3 folds, SB calls $0.07, BB calls $0.06

I have a tight image. I quite often get a chorus of folds whenever I raise. So I raise pretty much all pocket pairs if I'm first in MP1 and later. That assumes these guys are paying attention.
Also, since they mostly only limp or call when they do enter pots, if I'm going to get any money when I do hit, I have to start getting the $ in early.

Flop: ($0.24) Q:c T:c 8:h (3 players)
SB bets $0.06, BB raises to $0.21, Hero raises to $1.92 and is all-in, SB folds, BB calls $1.71

Bet Size?
I shoved because to be quite honest, I could not see what else to do.
Raise to 3x previous raise, and I'm at 1/3 stack, so I figure why not?
If I get called there are a lot of cards I don't want to see, so I'd like to take it down now if possible
