I've recently started playing Go and I would like to study some annotated 9x9 games, but can't seem to find anything. Does anyone know where I could find such games? If it's free that would be even better.
There is not much written about 9x9 Go games, but you can find a few videos about them on Youtube. I would recommend the following series of videos 'Crazy Nines', by Go content creator xhu98:
The series features Dan level amateur players discussing 9x9 strategy. This is the best 9x9 analysis I have been able to find.
