Greenhill Chess #3, 2014
For Beginners:
Dr. Root asked how to move a bishop from one location to another in the fewest number of moves. For example, "How can you move a bishop from f1 to f5?" (Similar drill will be done for capturing on f5). The student should respond either, "Bf1-d3-f5" or "Bf1-h3-f5." After one of those possible best responses, Dr. Root moved the bishop as indicated.
