UTG--a little loose preflop, a little loose postflop, but nothing to write home about. Have seen c/rs from him, though he's usually pretty straightforward

BB--Pretty good, I'd almost call him a TAG but he sometimes backs down when pushed. Gets a little shy, you know? Preflop is by the book perfect

**Though my question is specifically about the river, I'd appreciate comments on all streets.
