Turn and river lines?

I am playing a 90 player SnG, money bubble is 18. Currently there are 58 left.

I was recently moved, super small sample for stats with no reads.

Villan is running 86/66/50 for 3 hands
My preflop guess of a range is{A4s+,A7o+,K8s+,K10o+,QJo,77+, 67s,78s,89s,9Ts}
After calling a checkraise on flop {Ax,K9,T9,44,99-AA,Kdxd}

With such a small sample and Villan playing soo loose I am struggling with putting him on an accurate range. Please give me your thoughts on the ranges.. as that is something I am currently working to improve.

Q: Is the check on turn ok? How much should I bet on river, or should I check/call? I might be able to enduce a bluff from some busted Kdxd, or get a value bet from some KT-KQ.
