I don't seem to know how to play even the simplest hands.

I am new at the table - so no reads. UTG limps with a 113 stack, I raise to 9 with , BB and limper calls. BB started the hand with 186 and I cover.

Flop comes (27). BB now leads 20, and UTG folds. I just call.
Do I need to raise here to protect from the draw? Or am I better off just calling to let him continue to fire with a lower pair? Do I want to get all the money in here, without a read?

Turn (57) He bets 30, I raise to 95, he calls

River (147) He pushes his last 62, and I call.

Hmm, should I be happy to get it all in with AA on this type of board?
