Ahh, okay. I asked just to see if you're usually playing heads-up deep stacked or short stacked. If you're playing turbo STT's, you're probably playing pretty short, so you'll be shoving fairly often. Have you seen this page?
I have this linked saved under my favorites on my web browser. Basically, if your opponent is playing optimally, the chart tells
you which hands you should be pushing with what stack size. Of course, your opponent will never be playing optimally, so you have to make adjustments. So if your opponent is too tight, then it's gonna be profitable to shove super wide, and vice versa. It's a good starting point to go from though.
Generally, if you're not sure if you should shove or not, the better move is probably to shove, as long as the stacks are short and your opponent is not a complete drooler.
