bet the flop?

raise a lot more preflop.. at thoes limits =)

I would have raised .80 or.90

Checking a flop that has two to a flush is only okay when you *know* that it will be raised after you. When that happens, you gotta re-raise and make the flush draws pay. It also buys you some info about what the other person has. They might bet their flush draw out, but if they call a 3x or 4x re-raise, then you know they've got something, possibly something that can beat your aces.
