In competitions where both teams are tied and they have a tiebreaker, say in an academic competition and you are chosen, there can be a whole lot of pressure. You have people relying on you and if you fail you don’t know what their reaction will be. You also really want to succeed but you don’t know if you have the caliber to reach your goal. Extreme nerves and attempts to calm yourself are common. The main thing to do is to try and relax and do your best.
