Dr. Root taught en passant to the Intermediate and Advanced groups. After showing the rule on the demonstration board, each group tried the Create challenge from Thinking with Chess: Teaching Children Ages 5-14. This challenge involves creating a 10 move, notated game with three en passant captures.

For the beginners, who were still putting kings next to kings, Dr. Root taught an exercise with White king on e1, Black king on e8, and each side tried to get his or her king legally to the other king’s square first. Dr. Root also re-taught, and tested students on, the two rook checkmate to this group.
