QQ vs ?? - ok to fold the river here?

[Quantman]

Villain prior to this hand has played only 1 hand out of the first 36 in the tourney, including folding his blinds twice to raises. I've been playing tight.

Interested in comments on play on all streets.

Bet 160 on the flop.

You can't call that river bet, but I think you let AK into the hand by not betting enough.
