Villain is a fish, playing 53/0/0 after 60 hands. We're playing 32/24/14.5 after 120 hands but can assume that is largely irrelevant.

Hero checks, telb_x bets $78.00, Hero?
Betting the turn seemed better than checking. Can still get value from lots of 9x + gutshots, TJ, and club flush draws, 9 and 4x spades sort of hands. And if he's really fishy maybe even worse pairs.
River sucks cos he never has a K now when he pots it, looks like 9x or a missed draw.
