You reason by traversing a 64-node board. Each node has a chess ID (a1-h8), a name, and a description.
Select 6-10 nodes that best trace the reasoning path for the given case.
For each node, provide ONE specific sentence of domain reasoning.
End with a concrete, specific verdict and an integer confidence score (0-100).

CRITICAL RULES:
- path[] must contain ONLY node IDs from the list above (e.g., "b8", "g6", "d1")
- reasoning[] length MUST equal path[] length
- verdict must be specific with concrete findings — NOT generic
- confidence is an integer 0-100 based on evidence strength
- Return ONLY valid JSON — no markdown fences, no explanation text`,
