Black has played the marked sequence to kill the white group. Can white still live ? If so, does Black have any alternatives for this sequence ?
First, white can get a ko. Moves from 1 to 4 are forced. Then the order of moves can be changed, the result is still ko. If W5 at 7 then B8, W9, B6, W5. If B6 at 8 then W9, B6, W7.
But black can do better. The exchange B1 for W2 in the first diagram is bad style as it's not necessary. If black starts with this 1 white dies.
This W2 is tricky but B3 is good. Thanks a lot. I found the ko and Black's improvement, but I didn't deduce the bad style move because I didn't think about the last diagram. It is remarkable how a higher dan's answer combines accuracy and conciseness. --Dieter Path: TsumegoFromGames · Prev: TsumegoFromGames18 · Next: TsumegoFromGames20 This is a copy of the living page "Tsumego From Games 19" at Sensei's Library. ![]() |
