For a stop and go you need your opponent to be pot committed or nearly pot committed in that you are close to certain he would call your preflop raise. I think if he is stealing with less than what he had, there is a better chance that he folds preflop than calls, and with the OP's image, a good chance he even folds AJ. The idea of a Stop and Go is to give a person a second chance to back out of a hand if he misses or feels he is beat, and deny him a turn and river card. It is the converse of why you want to get your money all-in preflop with AK: so you can see all 5 cards.

Also, I believe you usually want a better hand here than AT to Stop and Go: if you hold 66-99 vs probable AK or AQ or if you hold AK, AQ vs a probable middle pair. Withe the frequency of Villian's steals here the is no reason to give him credit for that narrow a range.

I like the push.
