re: Poker & Calling raises with low to mid pocket pairs
With a low pair, I will almost never call a raise, unless I know for sure that a guy is super-aggressive and puts in a raise every time then I might.
With middle pair, I will probably call a late position raise if there were a couple limpers in the pot with me, but not all the time.
The one thing that it seems like you aren't understanding is that just because you have a pocket pair doesn't mean that you are going to get a set. You have a 7.5:1 odds
of hitting a set on the flop. After that, unless my pair filled some kind of a strong straight draw or I had middle pair that is still higher than any of the flop cards, I would not call any other raise past this point thinking I was going to hit that set.
