Sunday Problem #38

This is an original problem by me, inspired by a shape that occurred in an ngd league game. This is one of the few cases I’ve seen where a real-game position leads to a difficult and interesting life-and-death problem.

This problem included a small competition, where the first person to post the correct answer would get one month of Kifu …

Today at 1pm Helsinki time, Jeff, Antti, and Mikkgo will host the second ‘Go Jam’ on Mikkgo’s Twitch channel.

While the content of the stream is of course go-related, it is more geared towards the philosophical and psychological side of playing the game rather than particular patterns. As usual, everybody is welcome to follow and participate!



Sunday Problem #37

Black to play.

Solution
Solution (1)

Sunday Problem #36

Continuing with famous classic problems, this is problem 15 from Chō’s tsumego encyclopedia, advanced section.

Black to play.

Solution
Solution
Black’s 1–3 combination is the only order of moves that works. The main challenge in this problem is finding black 3, which becomes a kind of blind spot due to its bad shape.

Sunday Problem #35

Like last week’s problem, this is also from Guanzi Pu – and, in fact, also from Xuanxuan Qijing, where its title is (sui-raku-seki-shutsu). Literally this means a river’s water receding and the riverbed’s rocks’ becoming visible, but the figurative meaning is that of truth becoming revealed.

Black to play.

Sunday Problem #34

This is a slightly modified problem from Guanzi Pu. Although most of Guanzi Pu’s content is endgame (it’s even in the collection’s name, or Endgame diagrams), this is clearly a life-and-death problem.

Black to play.

Solution
Solution (1)
Black has no choice but to start by driving White down to the first line with 1–6. After this, however, …
