Ok youre in a cash game. Youre in early position. You pick up
AA 
Under the gun limps in. You raise to
4xBB. For the stakes we will say this is a
$4 raise. Theres 1 call and all else fold back round to the under the gun limper who also calls.
$13.50 in the pot.
Flop comes
J 8 3 ALL DIAMONDS
You look and yes you DO have the Ace of Diamonds.
UTG checks so you
bet $10, other guy folds then MR.UTG check raises you and
bets $20 which was double your bet.
So youve been
check raised and theres around
$40 in the pot. You both have about
$80 left infront of you.
What range of hands do you put him on and what do you do?
