This is a continuation of my PLO25 saga. So BTN is a TAG reg stealing about 45% on the button and is a 4tabling zoom reg. He cbets about 73% over a large sample size so he should be pretty merged here with value/semibluffs. His 2nd barrel is at 77%. He has folded to x/r on the flop about one-third of the time over 15 x/r spots. As far as history, he has run super hot and won every single big pot we've played.

Anyways, we make the defend here and I choose to x/r the flop as we have fold equity and we have quite a few good turn cards we can barrel on. He calls which I think will be with a range of mostly overpair+fd, T7xx, combo draws. I think he would mostly 3bet any sets or T7xx+high fd so I remove almost all strong made hands from his range. The turn is a question mark for me. Assuming he jams over our bet with 45xx and 98xx, what should we do here?
