I get dealt AA and raise it up, with a re-raise and a cap to follow.  This is a very loose table.  At the lowest limit at Doyle's Room (.50/1). 
  Flop comes Q 10 5 rainbow.  I bet, gets raised and the third player caps. 
  2 comes on the turn, I bet, get raised and now the third guy just calls. 

I find that I've been just switching to "check/call mode", even when they'll show Q Jor A 10 at the showdown. 
In these cases do I keep pushing?  Because they're so loose they can easily have Q 10, 10 5s even.  Any pair will hang around, and then they can obviously have a draw, set, or even an overpair.  I guess the question is when raises can't be used to gain any information, how do I play this? Check call? 3-bet?

On the flip side, I can see the raise as a great tool to freeze the action when I may not have the best hand.  Say I'm on the button with Q 10 s and raise a bet with a flop of Ks 10h 3d.  I can usually buy a free card if everyone checks to me on the turn.  Is there any other way to use this?
