Flop is Qh6d5h, hero check calls a bet of about 40% pot.

Turn is 4h, hero check folds to a bet of a little over 50% pot.

PIO likes the check call; it never folds the flop, and sometimes checkraises with either Ah or Jh.  Not surprisingly, it check raises more often with Ah.

On the turn, PIO rarely leads, although this is a card that real life Villains will check back a lot, so as an exploit, I can see leading here more often than the 5% PIO leads.  It's leads are mostly 66/65 for value as well as some K high flushes.  The actual hand is just a check.  It is indifferent to calling the turn, which, given hero's stack size means he likely made a good fold on the turn.
