If you are going to check the turn then why not check-3bet? MP is likely going to call. Button seems to have a clue based on his stats. No way he calls the raise if he doesn't have a flush and was bluffing. A J flush calls a raise, but might not call 2 back. He will never lay down the K here. If someone does have the K flush, they might give you some action based on your odd line.

What was your plan for the river?
