3-bet or call with the second nuts

[Mr Rick]

I would 3-bet every time, [especially if SB is still in - the action is a little confusing as described].

While a 4-bet has you beat mostly - you do mention that MP pushes draws and slows down mostly but not all the time when pushed back - so I would call it. She could have two lower clubs as well because she is loose... I would almost always call a river bet too (by this time there would be 19 big bets in the pot)- but would hate to see another club or the board pair up...
