FPS or well played?

[Deorum]

This is a hand I played last night in a very good, fairly
loose passive 20-40 game at Bay 101. To me, the hand stood
out as a little odd, and I would like some feedback on
whether you thought it was played well or if you think I was
trying to find some excuses for making some fancy plays.
Anyway, here it is:

9 handed, fairly loose game. UTG folds. I am next with
8 [img]/images/graemlins/diamond.gif[/img]9 [img]/images/graemlins/diamond.gif[/img] and limp. The action is folded to
a solid player in middle position, who is a little on the
loose side. He raises. His preflop raises have not been
out of line, but they do not necessarily mean big pairs,
either. He has been raising with big cards, as well as
wired pairs. The action is folded around to the blinds,
who both call. Four to the flop.

The flop comes 8 [img]/images/graemlins/heart.gif[/img]5 [img]/images/graemlins/heart.gif[/img]4 [img]/images/graemlins/spade.gif[/img] and the action is
checked to me. I bet. MP raises. This player is capable
of raising with big cards here to buy a free turn and drive
the other players out. The blinds fold, and I call, with
the intent of betting any turn that is not an ace. If I get
raised on a blank turn, I can be almost 100% sure he has an
overpair to my 8s. If I get called, I think there is a
very high chance that my hand is best, although there are
quite a few turn cards which may make him afraid to raise
an overpair, such as a 6, a 7, an 8, or a heart. Heads up
to the turn.

The turn brings the 8 [img]/images/graemlins/club.gif[/img]. Whoops. To be perfectly
honest, I was not anticipating improving on the turn. But
going along with my original plan, I bet. If he raises me
there, I plan to call and bet any river. I think that this
player is capable of folding an overpair to a 3-bet on the
turn, and I would like to get one more bet out of him if I
can. If he just calls, I plan to bet a heart, 6, or 7 on
the river, as these cards may scare him into checking behind
with a hand he otherwise would have bet. I will try to
checkraise any other card. He may bet AK here hoping I
will fold a busted flush draw that picked up a small pair,
and he will definately bet an overpair. He may also make
a total bluff with something like KQ, hoping I will fold
an ace high flush draw that missed or a small pair. He
thinks for a minute, smiling at himself. He appears to be
amused by the situation. Finally he weakly calls. I can
tell that he hopes that I have a heart draw.

The river brings the Q [img]/images/graemlins/spade.gif[/img]. Check check, he shows AK.

So was this hand played well, or was my reasoning totally
wrong in one or more spots?
