What I didn't say is that you'll get villain to fold often too. If you push, there will be three outcomes; they will fold and you'll take the pot. The will call with a dominated hand. They will call as the favorite. Weaker players holding AJ will call you down, but the J-9o's will probably fold. In my experience, they'l fold or you'll get called by a dominated hand often enough to make this a good play.

Being first to act after the flop is nice for a stop and go, but I still push preflop.
