This japenese Villain almost never floats AK, once he calls flop he has over pair, I bet turn so small to have 1010 jj or QQ call here, but he still folds, is it recycles to et 1200 or 1000 on turn? I don't like check to give him 2 outs to stack me if he hits but I m not sure what's highest EV , to check bet river or go even smaller than 1/5 pot

Villain tanks 5 min to fold to 2k bet into over 10k pot
