This is a spot that for some reason I struggled with last night on the paired board. Would love to know if you guys think I should just be calling here, or folding because we could be behind even with a 2nd nut flush possible on the river..
Don't fold 2 overs and a flush draw to a bet of that size. Sometimes you're still ahead (of hands like T9s) and you can show down king high and win if villain gives up. While flushes obviously lose to boats sometimes, you shouldn't be overly scared of paired boards.
As others mentioned, check-raising the flop is a decent option. This board is very good for your range in the BB, and you can often make villain fold ace high or a small pair on the flop, if not the turn.
