I would shove with any hand at least Q7 because at some point waiting for someone to bust may not happen. If it meant to be a winner it will happen and if not, keep the grind happening.
With a short stack, I prefer to play the push/fold. The main thing here is to avoid unnecessary risks and wait for a premium hand. But in this situation, you should also understand, that you can not let the blinds go through you. Depending on the opponents' game, it's better to put all-in even with a small hand to get a chance to double or take the pot on the pre-flop.
if a player is missing for the FT that means that you are already ITM with any decent hand I do all-in, I know that being in the FT would give you some more money but you already earned money, so you must risk and try to raise your stack to see if you are lucky and can win the tournament, so you must expand your range and hope to get lucky
In this situation, you need to play all-in pre-flop with a good card. It can be a pair or, in extreme cases, a nut pocket ace. It happens that single ligaments are cooler than any pair. See for yourself on the game and layout.
