Train One Skill per Game
Give each AI game one purpose: test a placement order, choose the right capture after a mill, or preserve mobility in the movement phase. Four search strengths change how deeply the AI calculates. Hints, undo, and move-by-move replay let you revisit the same position and compare alternatives instead of simply starting over.
Choose a Search Strength
Start on Beginner while legal moves, mills, and captures still require attention. Move to Medium when immediate mills and direct blocks are recognized reliably. Use Hard or Master to test double mills, mobility, and blockade threats. Increase the level only when you can explain why your move works and what the AI's reply threatens; one win is not enough evidence.
Use Hints to Compare Moves
Name two candidate moves before requesting a hint. For each one, identify the immediate purpose: form a mill, block a threat, claim a connected point, or preserve mobility. If the hint recommends something else, use undo to test both moves from the same position. After the AI replies, compare mill threats, material, and available routes; do not judge the candidates by the hint alone.
Review the First Turning Point
The final capture or blockade is usually a consequence, not the original error. Step backward until the first move after which your play became mostly defensive. The cause may be a mill closed without a return route, the wrong capture, or a stone committed to a poorly connected point. Stop the diagnosis there, return to that position, and test another candidate.
