Semi-bluff vs. Very Aggressive Villian

[BrassMonkey]

Villian is an extremely aggressive TAG who has a very high steal attempt percentage. He is also the type of TAG who would raise an ace high flop to fold you out of your lesser pair. When villian calls the turn raise, should I bet the river, or just check it down (give up)?
