Since the Denton HIgh School students attending this week had not completed Task B from last week, they did so today. Task B: Black pawn on the second rank (vary the file), black king on first rank (in front of black pawn); White K on g5, White Q on g8. White to move and draw or win, depending on what file the black pawn is on.
After students experimented for about 25 minutes, Dr. Root showed the solution. The solution is available in many places, including in the activity "Stalemate Surprise" in Dr. Root's book Science, Math, Checkmate: 32 Chess Activities for Inquiry and Problem Solving.
