I think a turn bet might have clinched this one, I might would have gone for a half pot sized bet on the flop and bet similar on the turn hoping to see a free SD. I'm not to kean on betting the pot on the flop with a miss as you usually have to follow it with a PSB on the turn can get very expensive. Obviously you have to 1/2 PB when you have a hand too otherwise you are giving away to much information.
