The pre flop play could have been fine if you were in position, but OOP KQ doesn t play very well.A call or a fold was better IMO.
Then on the flop you should have C-bet because you took control of the hand pre-flop and you can tell a story to your oponent that you ve got an overpair. If he calls you might then give up on the turn.(re-evaluate).
I would say with all the respect due that your two check call were pretty awful.
Sorry for my english wich is pretty awful too.
