Line check with AAxx

[crashwhips]

Here is a spot I often find myself in when I smooth call AAxx pf. Usually I just check/fold but this board was so dry I decided to take a shot. Should I just fold the flop here given that my plan is to give up if he calls? Should I lead the flop instead? If I'm going to check-raise, what is the ideal size of the raise?

Once my gin card falls on turn, is lead or crai better and if I lead what amount is good?

Opp is 63/17/2 btw
