For October 14, Dr. Alexey Root taught the Tandem Chess exercise from People, Places, Checkmates: Teaching Social Studies with Chess. Students in the A group partnered with students in the C group. B group students partnered together. Thus teams were balanced to play one tandem game as White and one tandem game as Black against another team. For example, a team of a A and C player played two tandem games versus a team of two B players.

Since usually students only interact with students in their own group, this exercise gave students an opportunity to get to know others in the Greenhill School Chess Club.
