Your moves should almost always be all-in or fold postflop. When a shortstack reraises a fullstack, it should send warning bells ringing. They want to be called. Easy read, and makes for easy decisions for the fullstack.

As a shortstack, you need to be always putting your opponents in tough spots that dont appear particularly tough and tricking them into thinking "eh whatever he's PROBABLY got nothing" or "Eh its only half a stack"

At the least, if the person does fold to your oversized all-in bet, it sets up that you "always" do that, youre probably just gambling, wanting to double or bust, and encourages other people call oversized bets in the future. "This guy pushes every hand, he could have second pair, third pair, nothing, i'll call"

I like to steal blinds a lot, thats probably just my personality, I'm still kinda "eh" about it as shortstack strategy.
