ask about one live 1/2 hand

villian : seems a young white regular (I moved to this table about 1 hour, no interesting hands on him), ~$240
hero with JJ at SB, ~$400

MP limp, villian raise button to $10, hero calls, both bb and MP call

flop 996 rb, hero checks(?), checks to BN who continue with $16, I smelled weak and mini raise(?)
both bb and mP fold, BN call.

turn 5, hero bet $35(?), BN call

river A, hero think and check; BN think a while and allin.  hero: call or fold?

Before this hand, hero raise to $12 with AA at BB after several limpers, only another white guy calls at EP (~200).

flop T44, hero checks, EP bets $12, hero raises to $30, EP calls;

Turn 3, hero bets 40, EP folds.

I show AA.
