I only have a 16 Hands Sample of my Opponent. He has 44% Vpip and 19% Pfr (33%Vpip from the CO).

On the Flop i decided to check and see what my Opponent is doing? He would call my CBet almost with any two cards anyways.
On the Turn i improved to TPTK and i took the initiative with a small Valuebet (its like 56% the Potsize).
Then he raised me to almost 4x my bet.
Because he played so loose, i thought he could have a lot of crappy two pairs including a Queen... He could also just made a straight with J9...

Let me know what i did wrong on this hand.
