95% of the time I reraise JJ here preflop but decided to overcall this time and play it a little different.

The guy on the button is unknown to me which is perhaps an arguement towards raised pf. It was my actually first hand at the table.

I planned on check raising the flop and took the buttons flat call to mean it was unlikely that he has an overpair but probably has a draw or smaller PP overcards to the board.

I think maybe I should of raised the turn? I dunno.

Was playing this passively okay?
