Details from memory- apologies...
Approaching the bubble in the 11r (55k) on stars. Hero has average stack (24k), villain covers comfortably.
Blinds 300 & 600 ante 50. Villain utg+1 makes it 1400; Hero 3 bets to 4.2k in mid pos with black aces. Villain insta smoothes.
Flop

. Checked to hero who bets 6k and villain jams. Decision time???
No reads on villain other than he proudly displays supernova badge (recently moved to the table & no history). Hero has a tight aggro image (altho he accidently min 3 bet/ folded one orbit ago whilst flicking between porn).
Are we good here? He has Ah x a bunch right?
