I was playing a PLO game in Macau - it was 8 handed I believe.  The hi-jack (Player A) limps for 200 with approx. 400BB - say 80,000 - he had been playing somewhat quiet this session, he's a Chinese professional who is capable.  I raise the button to 900 with QhJT5 (with two hearts, one spade, one club/diamond i don't remember) and about 350BB - say 75,000 - ... it's a 3 blind game, and the biggest blind (say player B) calls - he has both of us covered (approx 500BB) - say 100,000 - and A calls. I don't have many specific reads on B either.  He is part of the reason this game is going, he's a 40-50 year old chinese guy from out of town - but I've heard he is possibly a winning PLO player on the net - I'm not sure how large. I've seen him raise a few pots post-flop already this session, but never saw showdowns.  He is a little on the loose/passive side pre flop (not a ton of reraise isos for example) , though fairly aggressive post.

I realize preflop is a bit loose - but I feel a +EV spot to iso. the hi-jack limper very deep, not really the point of this post.

So 3 to the flop - it's Js 5s 2h - there's about 3k in the middle (making up numbers).  checked to me and I bet 2300, B calls and A folds.

2 to turn, myself and B - turn is 9c - 7600 approx in pot... he checks, I bet 6600 - he pots it to 27500 ... I have about 65k more in my stack... it's about 21k to call.

If I call there will be about 60k in pot with 40k in stacks.

What is the best play here?  If I call - what's the plan for rivers?
