I guess I made a mistake on the flop with this smallish sizing, the reason I did it is bcs I play vs fish who reacts aggressively on small bets and barrels any2 when he starts the action, so I wanted to trap him basically, was that a good idea at all? Also, if played like this can we fold otr? I mean if I fold otr then my whole passive trapping plan is non sense. So yeah, I'm a little bit lost in the whole situation 
Info on villain is pretty limited, random unknown fish who joined my table, he's calling 3bets 62% of the time (38% fold to 3bet), postflop stats are really limited due to small number of hands but have some reads that he is not giving up easily, aggression frequency is pretty high on all streets.
