    New Collection: 9x9 Endgame Problems

    There's a saying in Go that your overall strength is limited by your endgame strength. Even if you are leading a lot in the opening and middle game, mistakes in endgame can still lose you the game. This collection allows you to practice and level-up your endgame in a small 9x9 board with real-game examples.

    New Collection: Sacrifical Tsumego

    Sometimes sacrifices are necessary in order to kill, but how many stones can you sacrifice before killing? That's the question this collection aims to answer.

    New Collection: Yi Kuo

    Yi Kuo is a classical kifu and tsumego book written by Huang Longshi (1651-1700). It was posthumously published in 1710. Go Seigen once commented that Longshi's fighting skill was of 13-dan strength. The problems in this collection are focused mainly on endgame tesujis.

    Update 20.07.2023

    New board viewer: BesoGo

    We changed the technology that is used to display the problems from jGoBoard to BesoGo. There are various advantages, such as a tree display in the review, changing views without refresh, editing and saving problems on the website and more. It also opens possibilities to merge recurring board positions and to make a better result distinction. Instead of correct and incorrect, a future update is going to include more details.

    It comes with a separate editor which was the starting point to make this possible. Editor
