AA vs Shortstack - purposely weak?

[scotty34]

Villain in this hand has just over 4BB in front of him. Preflop he is slightly loose and very passive at 30/3 over a smallish sample. I have seen him donkbet several times on the flop from the blinds when facing a possible steal. I have never seen him showdown however, so I am not positive on its meaning.

After this donkbet, I decided that I wanted to get as much of his money in the pot as possible, and I can't imagine folding my hand at any point. I don't know if this was a good plan or not.

River: (5.50 BB) 9[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players)</font>
SB checks, <font color="#CC3333">Hero bets</font>

After this check on the river, I am fairly confident that he would fold any bluff/busted draw, and check-raise anything else to put his last 1.5BB in the pot.

Given the scenario, did I misplay my hand? Was the river bet OK (I don't know if this is as easy as at first glance)?
