I called instead of 3bet b/c:
1) I had the btn, if I was in the blinds I would 3bet
2) A player with pfr of 15 could be raising closer to 18-20% here in lp, I felt a 3bet would fold worse and hands that continue are either better or flips so I thought keeping his range wide was best.

That ws my reasoning anyway.

I can agree with everyone that the flop shouldve been larger
