I really see no problem w/ the way you played it on any street. pre-flop and flop are fine. turn and river are tough decisions but i certainly understand why you played it that way. You called the turn hoping he's bluffing AND that he'll then make the mistake of giving up on the bluff on the river. You weren't willing to pay 2 bets to catch a bluff, but was willing to pay 1 bet to catch a bluff plus opponent's river mistake.
With your strategy, you were getting 8-1 return, which you deemed worthwhile. Calling both turn and river would be 9-2 to catch a bluff which you didn't think worthwhile.
Of course, most important consideration here is not how your opponent plays but how he thinks you play. That's why it's a mistake to routinely play like this, but since he has no read on you, it's probably okay.
