$50PLO, Best way to maximize my potential freeroll?

Note stack sizes. Opponent actually seems somewhat competent. Maybe a tad loose PF but postflop pretty smug.

good post, I swear whenever I three bet a big made hand on the turn they fold and every time I just have the big draw they have bottom set and snap shove... my instinct is to pot to get as much money in now so he'll feel tied to the hand.

Well at 50PLO no one ever raises this turn w/o the joint. So the question is do I want 175bbs going into the pot on this turn?

2nd nut fd, no boat draw, no AJ/AT. I'm not quite sure what the best amount was if 3betting is in fact the correct move.
