Dr. Alexey Root reviewed what happens when the defending king can occupy the promotion square. That is, she reviewed last week’s lesson of king and pawn versus king draw and the Philidor’s rook ending. This week, students looked at what happens when the defender is driven away from the promotion square. Students tried white pawn e2, white king e4, black king d6, White to move.

After students played through this ending on their own, Dr. Root showed what should happen. Then interested students tried the Lucena rook ending and then Dr. Root showed how to “build a bridge.” Other students not interested in the additional Lucena instruction, or who already knew that ending, played for fun.
