AQ, very tough hand, what line?

[Up-grey-de]

I just opened up this table, so I have exactly 100BB. Villian covers me. No tells whatsoever.
NL 6-handed 1/2. Hero is dealt AQo.

UTG limps, Villian makes it 10, Hero calls in BB, so does UTG.

Flop: 7 heart, A diamond, 10 clubs.

Hero checks, UTG checks, Villian bets 20 (pot is 31.)
Hero calls, UTG folds.

Turn= 9 spade
Hero checks, Villian bets 50, Hero calls.

River= A clubs.
Hero checks, Villian bets All-in.
(Pot is 131, I have 70 left)

Question 1= Would anyone raise this flop?

Question 2= Could anyone fold this river, if so, why?

Question 3= Would you like a turn fold, esp since I have never played with Villian before?
