Did I play it badly?

[Luckboxxx]

This was a $7.70 rebuy tourney, 60 people left out of ~270 and 30 spots got payed. I was somewhere around 13th-15th in chips. Villian was pretty passive player, and not very good post flop, I was moved to this table 10 minutes before this hand took place, and saw him open limp hands like AJo,AQs, KQ on the button before. He was also pretty passive post flop.
