I figured i would lead flop and see what happened. After villain called i assumed he had a weaker ace like AQ or AJ, perhaps a flush draw or even a frustrated overpair. Thus, the check-raise on the turn. His push kind of had me worried but i was fairly confident i was ahead here, possibly splitting. Villain had like 9% pfr so i think AQ or AJ are in his range, but also i dont necessarily think that he would raise AT in early position. Thoughts?
