I have a really hard time understanding why you always have to raise with hands like TT preflop. Dont get me wrong, I do it every time when I play short-handed, or think I can pick up the blinds, but on a full table?
Is it because I play micro limits? Maybe at higher limits you can isolate
someone with TT but it seems at the limits/tables I play, there will be at least 3-4 people looking at the flop and there is a huge chance that at least 1 player catches something that is worth it for him to go all the way to the river no matter what I do.
And that will usually be a higher pair, so unless I make a set, Im done.

Right now on a full table, I limp with any pocket pair < TT and hope for a set (unless like I said, I think there is a chance that I can pick up the blinds, or it is short-handed).

I know it is probably wrong not to raise TT as so many good players advice it, but I feel like I shouldnt make a play until I really believe it is correct
