"Sente gains nothing"

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.

Play Go

Playing long serious games is very important to improve. Our league system encourages you to do so in a friendly yet competitive environment. On top of that we reward our winners with cool prizes every month.
