is this a "guess my hand" post?

and why is a 1/3 pot bet a donk bet?

given his play with the A9, you're obviously not pushing him off any kind of hand so what you actually have is pretty important here. weak players are the ones you rely on to pay you off when you have them beat ... trying to get fancy if you don't have a hand doesn't usually work since they are hard to bluff (just ask Annie Duke).
