Hero is in the BB with AJo and $240 stack.
Villain is UTG and makes it $20 straight, 4 callers to me, I call. Everyone covers Hero who is short stack.

Flop comes: 8d Ah 5h (pot $120)

Hero checks, UTG bets $100, everyone folds to Hero who goes all in for $227. Another $127 for Villain to call.

Villain thinks and calls.

Turn is: Jc

River is: blank

Hero has two pair (A's and J's)
Villain has a set of J's

What the heck was villain thinking calling my all in raise?
Did I play this wrong? I probably should have fired into the pot on the flop first.

Any comments appreciated.
