WCOOP ME - Boat's sailing on flush river. check or bet???

[mwalsh2020]

highly unlikely villain has a flush esp if he's a decent player, why would he call after an utg+1 bet and a raise by you on a paired board with only a flush draw... i suppose you could give him the t9hh or the nut flush draw but i think its far more likely that he has an 8 and is trying not to get too crazy with it. I doubt he'll be that scared of the flush but it is one more hand that he probably can't beat since i'm guessing he has something like 78/89/t8s. I would bet 15k and hope for a call, but i wouldn't expect him to push.
