Is this a good lay down or insta call?

550 satellite. Top 11 get a seat into a 2650 event.

Down to 14. Hero's image is very TAG. I've only shown down top ten hands. Villain has been chip leader for awhile. Got two full houses and Aces 4 times in the past hour. We both know we wouldn't raise each other's blind w/o a very good hand. He gave me a walk one time when I was in the BB he threw away AQo. Pre-flop he's raised to 8-10xBB and shown AA each time.

Table is playing extremely tight. It's been folding around to the BB unless someone picks up AK or JJ+ in which case they go all in pre-flop.
7-handed
Blinds are 1500-3000 w/ 300 antes.
Folded to hero in CO. Hero has 31k Villain has about 50k

folds to villain in BB.
He thinks and hesitantly calls and checks blind.
