[Aisthesis]

Well, the only reason I would have probably just flat called that particular flop (as you did) rather than making a strong raise as continuation bet/semi-bluff was the possibility that SB might have JT and price you out of the flush draw.

I still don't exclude this possibility, as he may have expected you to bet when you hit the A. Another option is AQ (I'm surmising that's what you put him on?). BB looks to me a lot like he was drawing to a little flush and made it on the river.

I think I'd just make it around $60 to go here and see what happens. You might get lucky and get a raise from a lesser flush (or even the straight), but I think there's a decent chance that they'll both just flat call. It's really just a moderate "selling your hand" bet.
