(;SZ[19]AP[MultiGo:3.3.0]C[These comments are what I can remember from Ming reviewing the game with me two days ago. He has gone over it with Kevin and with his profesional coach - so the analysis should be fairly robust. It's quite different what my take on the game was - see analysis 1. Be alert for mis-placed stones in the variations! I'll do my best to convey what Ming said, but there will be mistakes.
