So it's all right to raise AJ but only mid to late position, or do some of you put in a small raise in EP ?

I think I like the half pot idea when you pair but there's an over on board, then the only thing you have to worry about is a caller instead of a fold or raise as you wont really know what the other person has.

I find there's very little raising, 3 or 4 betting at microlimits and it can get frustrating as I like to bet and raise for information but others dont play that way many times so it's hard to put people on certain hands when you're not getting the information you're looking for.
