Davide Grasso, an ngd student, has this September created a training league with the aim of allowing its participants to play serious games in a friendly environment. …
Sunday Problem #70
This problem is arranged from a shape that appeared in a recent game between Oscar and Lucas Neirynck 6d. The presence of White’s t14 stone affects the corner considerably, and the correct solution is nothing short of ingenious.
Black to play.
Solution
The position of white ‘a’ suggests that black 1 should be an efficient move for procuring …

Sunday Problem #69
I arranged this problem from a shape that appeared in one of my teaching games. The killing technique involved is not too special, but usually appears in the corner rather than on the side like this.
Black to play.
Solution
Black 1 is often a key point in this kind of a shape, but unfortunately so is white 2. …
Sunday Problem #68
This is an original problem arranged from a shape that appeared in a recent tournament game by Lukáš.
Black to play.
Solution
The peep of 1 looks tempting, but is actually a mistake. After white 2, the white corner cannot be captured; black 3 is probably the strongest attempt, but after 4–8, the miai of ‘a’ and ‘b’ …
Sunday Problem #67
This is a classic tesuji problem that appears for example in Lee Chang-ho’s collection of tesuji problems.
Black to play.
Solution

Sunday Problem #66
This is a difficult variant of a classic tsumego that showed up in my recent lesson with Oscar.
Black to play.
Solution
The hane of 1 is one way for the black group to live. If White descends to 2, Black jumps to 3, making a miai of ‘a’ and ‘b’.
Things get more complicated if …

Currently it is still possible to join for the regular two months in September and October: the full option is €80 and the half option €50. After the September league starts, we take one-month subscriptions for October: these are €40 for the full option and €25 for the half option.
Sunday Problem #65
This is an easier classic problem to counterweight the recent difficult problems. While the solution sequence is straightforward, it is however still quite long and makes for good visualisation training.
Black to play.
Solution
Pretty much the only thing Black can try in this problem is the 1–3 squeeze. Following . . .
