Go Problems

I'm so happy I have a color printer (Canon Pixma 4000 with CD printing tray - not available in the US due to patent issues). Go problem diagrams are much better readable that way, especially when you like to design algorithms on the couch and you don't own a laptop.

I want to dig deep into understanding the issues related to solving Go problems, to test ideas for a TsumeGo solver.

It turns out that Denis Feldmann has an interesting collection here.
As a terrible Go player, I need solutions as well, so his collection is exactly what I was looking for.
