Greenhill Chess #19, 2014
Greenhill chess students played Progressive Chess today (Scottish variation). Briefly,White starts with one move, then Black plays two moves, then White plays three moves, and so forth. Dr. Root noted that a turn ends when check is given and that the checked king must use its first move to get out of check. And that it cannot move into check during its turn. The variant teaches students to make every move count and to plan ahead.
