When time is called in a Two-Headed Giant event at the end of a Swiss round, what happens?

In a Two-Headed Giant event, when time is called at the end of a Swiss round, the correct procedure is to play three additional turns before declaring a draw if the match is not finished. This rule ensures that both teams have an equal opportunity to play and potentially determine a winner, while also providing a structured approach to resolving the match. Each team is given the chance to play during these turns, allowing for the possibility of changes in the game state that might lead to a victory.

The choice to allow three additional turns is designed to maintain fairness in matches that are still active at the time time is called. It ensures that the game doesn't end abruptly without allowing players a final opportunity to influence the outcome.
