When can teammates in a Two-Headed Giant game discuss their strategies?

In a Two-Headed Giant game, teammates can discuss their strategies at any time during the game. This includes moments during both their own turns and their opponents' turns, as well as at the beginning of the game before play starts. Open communication between teammates is a crucial element of the format, allowing them to coordinate their plays and tactics to enhance their chances of winning.

This capacity for constant discussion helps to foster a collaborative environment, as players can bounce ideas off each other and plan their moves more effectively. There are no restrictions on when this dialogue can occur, emphasizing the teamwork aspect that defines Two-Headed Giant play.

The other options suggest limitations on when teammates can communicate, which does not align with the rules governing Two-Headed Giant games. Effective collaboration is fundamental, and these restrictions would hinder the dynamic nature of gameplay that the format is designed to promote.
