10/20 - Strange lines

[Pog0]

1. Generic question. I raise pf. Non-tag calls. He bet/3bets the flop and then screwplays the turn. Is this always a monster? Usually something that improved on the turn, right?

2. A slightly different strange play:

Villain is 39/21/2.4
he has c/r the turn 0/8
c/r the flop 23%
won showdown when raise turn 3/3
