AA faces aggression on multiple streets

[valdiesel]

Ive been playing 20/17 solid poker and showing down good hands. This opponent has been around for a bit and is running at 32/7. Ive been stealing his blinds constantly without any aggression from him.

1. Do I 3bet the flop or wait to make sure no scare card comes on turn and then c/r
2. He pots turn, is this a fold or what?
