I'm a retired mathematics professor. I live in the western part of Massachusetts, USA. I have published numerous translations from Japanese into English in the American Go Journal. To me, finding good moves is more important than winning.
I rarely play in tournaments. My current playing strength is around AGA 5-Dan.
As practice for me in making diagrams, here is a life-and-death problem I like because it is a shape that could occur in an actual game. It's got a lot of variations to read out. It was composed by Fujisawa Shuko around 1944.
