Trip aces on the river?

Still thinking about being more agressive on the rivers... But I don't know if it's worth three here.

Nothing wrong with just a call on the river here. I think it is also read dependant. If the guy likes to bluff at the river, then reraise. If not, there is no shame in just calling the raise.

Looks like just a river call.

His flop raise and turn check look like a botched flop free card play. Maybe QJs or QKs.
