You're trying to apply your own logic for villain, just because you think its 'bad' to bluff turn for half pot after you overbet flop doesn't mean he will think the same. Same logic applies for him thinking he's committed.
I know from experience that this isn't true at all. (I've seen multiple 'maniacs' ship their last money in with less than 1/2 pot or even 1/3pot behind with complete air.)
Also OP posted this read :
"When checked too he bets 100% w/ his complete range. Overbets the turn almost everytime. "
I don't get why it keeps getting ignored. If your plan is to bluff catch here with that read check/calling twice is almost always going to be better than check/shoving, unless you know for sure he wont double barrel on this board.
agreed...i might even be tempted to ship over the turn over bet on a brick none club for value.
