$100 live tournament
20 players to start, 8 players remaining
Blinds are 150-300 with 25 antes
Avg stack: 7,000 - Hero has 5,500 - Villain covers

Villain opens from UTG to 1,500
(a rather large raise, his standard raise has been ~3.5x BB)
everyone folds to me in MP and i see A[img]/images/graemlins/spade.gif[/img]K[img]/images/graemlins/spade.gif[/img]
Is this an auto-shove or can I just call and see the flop?
btw villain is a solid player who almost never gets creative/out of line
