Bet more on flop especially against calling station. He may have paired his K or J and is likely to call a larger bet with your read and this is where you get value. You're still likely ahead here. On turn I'd bet at least half the pot, you're giving him drawing odds here, especially if you're not going to be able to fold to a re-raise on the river. On river I would either bet at least half pot or not bet at all if I was worried about my hand. With your reads though, I'd bet on river.
