Handling a short stack in a tournament requires a strategic approach. You should focus on preserving your remaining chips while maximizing opportunities to double up. This involves playing tight-aggressive poker, selecting the right moments to shove or call, and managing your risk. It's essential to balance the need to protect your stack with the urgency to accumulate chips before you're blinded out. By making informed decisions and adapting to the table dynamics, you can effectively manage your short stack and potentially make a comeback in the tournament.
