Baduk Tesuji 1000: Go Problems

Solve Go problems with no ads: 1,027 tsumego (life-and-death), tesuji and endgame puzzles chosen from the classic collections that Go masters have studied for centuries. Baduk, Weiqi or Igo — it's the same game. No timers, no energy bars. Just sit at the board, read ahead and find the move.

Wrong moves get punished by a Go AI

This is not a book of answers to memorise. Play a wrong move and a Go AI answers for real, showing you exactly how your stones die. Find a different move that also works, and the AI checks it and counts it as solved. Great for self-study, reading practice and improving your Go rank.

1,027 tsumego, tesuji and endgame problems

• 688 life-and-death problems — live, kill, ko and capturing races (semeai)
• 214 tesuji / brilliant-move problems — sacrifices, under-the-stones, chases and centre fights

Sorted into stages from easy to hard, for beginners up to dan players. Solve 7 of 10 to open the next stage, or browse by collection.
