"The only thing worse than knowing that it didn't work is not knowing that it did work."

Let's get better together

Study Go

Ask stronger players to help review your games, study pro games or tsumego. We also organise lectures with strong teachers. The global idea is you get taught by the stronger while you teach the weaker.
