On the flop , I hit bottom set and called. On the turn/river could I use the flush board and steal ?

You don't block any hearts and there was no raise pre. So he will have flush a lot. Very weird for him not to open this hand pre.
You played it perfect imo.

well played, I would've lost more (check/raise/going broke on flop against the shorty all day)

so I guess the villain was "trapping" preflop?

Glad our hero didn't fall victim to it with his monster

I would have lost more money too lol
