I see an overpair or flush draw being played like this more than top set to an opponent that checked. This guy would also push a bunch of hands you do beat.
As for a bad way to play it? I push everytime at lower stakes in his shoes, 2/4 I will push 25% of the time, and it is totally opponent dependant as to who I will push against, figuring I can't fold a flush card on the turn they might bluff at with AJ one of the suit, and need to get to the river. I rarely play anyone that I think is willing to call that bet unless they frequently limp UTG with AA
Edit: By lower stakes I mean micros.
