Dr. Alexey Root taught the en passant rule using material from Children and Chess: A Guide for Educators to all three groups at Greenhill School. The beginners then paired up to play Pawn Games and raised their hands when en passant opportunities arose in their games.

The intermediate and advanced students created challenges where the last move was pawn takes pawn en passant checkmate. The advanced students additionally played Pawn Games where they raised hands if en passant captures arose.
