[JJack]

intersting hand.
at flop you have about 40 equity vs PFR

Board: Kd 7d 5c
Dead:

equity win tie pots won pots tied
Hand 0: 60.824% 59.50% 01.33% 21205 472.50 { TT+, AQs+, AKo }
Hand 1: 39.176% 37.85% 01.33% 13490 472.50 { QcQh }

Also you beat only JJ and less probably TT or AQs.
I also dont see many hands at limper range that we need protect our hand vs him (A7s, A5s - any suited diamonds will call anyway) even that pot is large.

Also what you do if PFR will 3bet flop?
You dont have enought impied odds to catch your 1.5-2 outs to set QQQ and I dont like raise/fold line.

I think I would just call down.
