I had to cut and paste. I only left in the relevant stuff (I think),

Hero checked (going for the CR, thinking he was going for the diamond flush).
Villain checked (damn).

Board cards [4d 8s 2d 8d Ac]
Pot $0.58 [2 players]
Hero bet $0.50
Villain called $0.50 and raised $2

So... why'd he reraise?
I'm hoping he's slowplaying a flush. 84 and 82? UTG calling with either of those hands-- I don't think is real likely. If he had one of those hands I'm thinking he'd have raised the flop to protect against the diamond draw (though at these levels, who knows if he's even thinking).
A8? One realistic hand beats me (well, 88 does also but again he should've raised the flop to protect the draw, right?) and he might have that. Trip 8's at this level do this also (89, 87, T8). All-in worthy or is the possibility of A8 or 88 enough to downgrade this to just a call?

Flaws in my thinking? Did I misplay a street anywhere here?
