KQo with maniac on board

[Lurker4]

I'd lean towards 3-betting the turn/calling down a cap with your description/stats of MP3, he can play a strong K/hearts this way and you are obviously ahead of SB. I don't know if I can fold this river getting 21.5-1. with SB's stats he has the flush nearly always but I don't know if he has KT/KQ + you beat MP3 more than 4.4% of the time. I'd make a crying call but I'm not sure if that is correct.
