I like checkraising this flop since MP3 will usually lead at it.

You have to be more aggressive with a flush on the turn and river. On the turn with the button staying in you MUST threebet and cap if possible. The button's call of two cold looks like a possible Ks and you must charge the max to be outdrawn!

Three-bet the river and call a cap. Why do you think you're beat? Just because you got raised on the turn in a big pot by an unknown? Remember that when you lead a flop like this, most players WON'T put you on a flush draw. His AQ or whatever is looking really good to him and he doesn't want another spade to hit, so he is raising you.
