Turn an AI answer into a decision you can use next game.

Eight standalone guides cover review practice, online SGF analysis, a KaTrain cloud engine, and five deeply read games from the Edo period to the AlphaGo era. Each article tackles one question with steps, sources, a real board, and playable variations.

1. How to review a Go game with AI

   A deep review routine that avoids chasing every number: reconstruct your thinking, find turning points, compare why the played line and three KataGo routes differ, and keep lessons for your next game.

2. From SGF source to KataGo TreeView

   Start with FF[4] source text, learn nodes, properties, coordinates, and variations, export from OGS, KaTrain, Sabaki, or SmartGo, then analyze the record with Read19 and KataGo.

3. How to connect KaTrain to Read19 cloud KataGo

   Keep the KaTrain interface on your computer while Read19 runs KataGo in the cloud, without configuring a local GPU.

4. Jowa's blood-vomiting game: three ghost moves under institutional pressure

   The legend promises divine inspiration and a defeated prodigy coughing blood. The board is harsher: Jowa did recover and win, but modern KataGo sharply disagrees with the traditional praise of the first ghost move.

5. The ear-reddening move faces four ways while AI calls it a loss

   Black 127 landed near tengen. A doctor supposedly read the moment not from the board but from Gennan's reddening ears. KataGo now offers a useful objection: magnificent direction, questionable urgency.

6. Go Seigen turns 3-3, star, and tengen into a manifesto

   In 1933 the board's greatest institutional authority sat as White. Nineteen-year-old Go Seigen answered with territory, speed, and then a stone at the exact center.

7. AlphaGo's move 37 made everyone ask why

   P10 was not magic. It pressed White low on the right while preserving freedom toward the center. What felt alien was a priority humans rarely chose, expressed through perfectly legible Go logic.

8. Lee Sedol's move 78 did not instantly reverse the game. It did something harder.

   Modern KataGo still gives AlphaGo about 98.7% after L11. The move deserves its name because it creates a corridor of concrete questions where one machine error can rewrite the match.
