It's supposed to be a check right?

[Dire]

The turn/river are fine. Like expected from a $200 live player he made a horrible sized check raise (which he never makes with worse) giving her acceptable odds to draw out. She misses so she folds which is fine - she's never ahead on the river. Doesn't matter if she's getting 10;1 or 1:1.

I also believe underbetting the turn is best, or at least better than making a real bet on the turn - which is worst by far. Live players are pretty bad, but I think even a horrible player can get away from a mediocre king if she bets significantly on the turn - while they're rarely tossing second pair for just another half pot bet.
