Managing a short stack in a tournament requires a strategic approach to maximize your chances of survival and potentially accumulating more chips. This involves being highly selective with your starting hands, looking for opportunities to shove all-in with strong hands to minimize risk, and being mindful of your table image and opponents' aggression levels. Additionally, you must carefully consider your position, the blinds, and the payout structure to make informed decisions about when to take risks and when to conserve your stack.
