Choose the moves, test the resistance, judge the result
Each position checks four over-the-board habits: finding serious candidates, identifying every critical defensive branch, keeping the line accurate and evaluating where the forcing play ends. Each hint costs five points.

After your first move, which reply is hardest to meet? More than one move may receive full credit.
Play one reviewed branch on the board. Each stored defensive reply follows its own continuation. If an equally strong root has no forcing continuation in this exercise, it becomes the evaluation endpoint instead of being marked wrong.
