hi assasin, welcome to the forums!
This is a situation where we have 10Bbs so our pre-flop decision is push or fold.
And, because the short stack is out of the hand and has significantly less chips than you, you need to be very tight in this spot. You can shove a lot of value hands against tight players something like A8o+ 66+ KQs looks good to shove pre-flop as a default range. But you need to adjust that against looser players by folding some of the bottom.
Our focus here is not to increase our lead over the ss, but rather to survive and make it in the money! The chips you gain are basically worthless because you do not gain any significant equity advantages in the tournament (ie. by becoming the chip leader or something), BUT you are risking a LOT of equity by getting involved with the chip leaders when there is still a vulnerable SS around.
So folding this pre-flop is the best play.
Keep posting more hands and welcome!
