no reads on villain. Assuming most types of opponents, the possibility that he's trying to push me off aces (or other premium hands that I may raise with from the small blind like j 10 9 8)combined with my acceptable equity against many draws and the low probability of him having a set makes this a push, right?

Is calling the flop and pushing a non-threatening turn an option (a standard play from NLH)?
