Flush on turn. Missed value or correct play?

Bovada 10NL (6-max)

The SB has been playing fairly sensible, conservative poker up to this point.

UTG $ 9.00
UTG+1 $11.65
MP $ 4.05
CO Empty Seat
SB $12.35
BB (Hero) $10.12

Hero dealt: [7 9]

UTG Limps .10, fold, fold, SB calls .05, Hero calls (Pot: .30)

Flop: [A A K]

SB checks, Hero bets .30, UTG folds, SB calls .30 (Pot .90)

(Given the dangerousness of the flop, I thought it best to bet out on the flop as a semi-bluff to rep having an A, and possibly take the pot there.)


Turn: [8]

SB checks, Hero Bets .90, SB raises to $2.50, Hero calls $1.60 (Pot $5.90)

(Okay, now I know that the SB has some kind of hand. He may have come in with a weak ace, let me lead the flop, and is now lowering the boom on the turn, or he may have just made his flush draw, like I did. He might have had A-8, and now has a full house. Given his pre-flop betting, I doubt that he had AA, AK, or KK, but it's possible that he slow played up to this point, being that he was in the SB with very little pre-flop action.)



River: [Q]

SB bets $3.75, Hero calls $3.75 (Pot: $13.40)

SB now takes the lead in betting with a 2/3 pot bet, which given the strength that was previously shown, looks like a value bet that is courting a re-raise from me. Looking at my hand, I am being beaten by AA, AK, AQ, A8, and any club flush where he holds a Q, J, or 10. Rather than re-raise, I call.
