Hey Nipbourne,
Villain is usually weak (or trapping) on the flop after he doesn't cbet. I prefer a smaller bet.
The
K
is a bad card for villains range. You may be able to extract value still, but again, I prefer a smaller bet, perhaps $0.80 or so.
Again unless villain has spiked an Ace you are not getting called on river. Smaller bet might be good. Vs a lot of opponents you should fold river vs check/raise. CO looks pretty bad though and may be doing this with an Ace or worse 2pair. If you'd bet smaller during the hand you might find it possible to get away here.
