Yes, I would push 10-15% on the flop with TpTk. Another creative idea would be a check-raise on flop if you feel he will bet into you. In terms of a scare card coming up, your action depends greatly on your position. Acting first, I would continue betting. If you bet on flop and check on turn and he bets on the turn, you don't know where your at. The only way to gain information in this type of situation would be to come back with a raise. You can't let a LAG player run over you.
