This happened to me too way more then once. I see someone raising pre flop, and several people who just call. I end up on late position or on the blinds with a very good hand like AQs AKo AKs. Since the stacks are never that big, there is no point in just re-raising with quarter or third of the stack. so I shove. Always get called by a small pocket pair.
Reason I shove is that I believe that if anyone had a hand good enough to shove or call a shove would do that themselves and not risk a family pot. So I want to punish calling with wide ranges by squeezing with
hands as strong as once mentioned above.
Considering how many times I got called by small pocket pairs and had to coin flip, I am starting to change that play into just calling, and taking it from there.
However, in case I am the shortstack, I am still shoving.
