Solutions (p8, p15, p17)

British Go Journal No. 63. [1] November 1984. Page 31.

The problems to these solutions are to be found on page 8 [2], page 15 [3] and page 17 [4].

Solution (p8)

Black 1 is the only way to connect.

Solution (p15)

Black 1 in the left hand diagram doesn't work. This forms the "J" group, which is unstable and can be killed by white 2 - 8 (the order of 2 and 4 can be reversed). The way for Black to survive is to play black 1 in the right hand diagram, which becomes ko as shown.

Solution (p17)

White 1 is a surprising move, but it is the only way to stop Black from playing A with eyes available on either side (white A fails to black 3).
