I always reraise here from the SB with small pocket pairs. You cant call, because its very important to get the BB out, and to play these hands well you need to have the initiative IMO. From the flop on you want your opponents to fold at every possible event, unless you hit your set.

This can only be done IMO if you´ve shown aggression preflop. Then a bet on a Kxy, Axy, blablabla flops often buys you the pot. BTW...I would nearly always bet the flop, no matter what falls. Then, depending on opponents reaction and texture of the board your main decision should be IMO if you go to showdown. If your opponent is very aggressive, and you decided you very well may have the best of it, then a check-call approach is fine IMO. If your opponent is aggressive but capable of folding, then you might want to push it hard on some flops. Like a JJx flop. If the flop comes.....blablabla....there are so many situations, but with small pocket pairs your main consideration on the flop, after you have bet, should IMO be if you go to showndown. How you gonna do that afterward is often pretty straightforward.
