Table has been pretty loose and splashy. Main villain older Asian guy i've played with a few times before. He seems to get very sticky with over pairs and has some unorthodox lines and sizing. On the flop if he is the aggressor preflop he will bluff with a very wide range and barrel, but as the caller he seems pretty straight forward, but chases a lot. Hero has a tight, semi nitty image in his eyes.

Question #1 Should I fold this preflop (typically it's a fold, but getting a great price)
Question #2 Is turning my hand into a bluff a thing on the turn?

UTG open $20, 5 callers, Hero BB 7h5c calls.
Flop ($140) 8d-7d-7s
checks around to btn who bets $50 (loose aggro player capable of betting random hands like KQ here with no pair or draw). I flat call. UTG calls, and now MP comes a live with $250, BTN folds, I call, utg folds. HU to the turn (BB vs MP).

Turn ($740) 8d-7d-7s-Kd
Hero all in $800, MP ($475) ??

I felt like MP has 7x here a lot and I can potentially just fold the flop given my read. Once in a great while he will spazz out with something like 99 on the flop trying to protect his hand. Question is, does he ever fold 7x here on the turn given my line looks like I just made a flush, call flop bet, call Xr, then donk shove for 2/3 pot on the turn.
