100NL - Is this a value shove or a bluff?

[MaaaaaaaaX]

Villain in this hand had been very tight. Not played a lot of hands and this is the 1st time he has 3-bet.

I have been playing quite aggressively at this table so far and have built up my stack without really showing down any hands.

Not really sure what do to on river. If call or fold what kind of range do you give him here? All comments appreciated!
