All three St. Vincent’s chess groups tried the Game Theory lesson from Thinking with Chess: Teaching Children Ages 5-14. Basically, the challenge is "whoever castles first wins." Dr. Root reviewed the rules of castling with the beginner and intermediate students beforehand. The advanced students already know the rules of castling.

With the advanced group, Dr. Root taught the king and pawn vs. king draw, which is like a dance. Three girls volunteered to demonstrate the dance. The king and pawn versus king draw is related to the Philidor’s rook and pawn vs. rook lesson scheduled for next week. The advanced group concluded with solving four mate-in-one problems created by their classmate, Luke.
