in general i was wondering:

when you limp in with a low pair, do you want to avoid this in early position (first three after BB) ?

also, if you limp in with a 1xBB, then someone raises you, how do you make the decision to call... i'm thinking it depends on how much the raise is (lets say no more than 1 or 2xBB), as well as how many people are deciding to stay in as well as what your position is right ?

if only two people decide to call, why bother as there wont be enough people to take money from if you flop the set - correct?
