QQ party poker 10/20, titans clash again

MP2 is our villian, he is 24/17/2.7 after around 500 hands.

What do you do after he donks the turn? Suggest a line for the river as well please.

We also clashed earlier in the session, that hand history follows the one I am questioning now. It has results included.
