Tsumego (1) Answer

Here is the answer to tsumego(1).



The correct answer for this tsumego is R18. By playing this, black is avoided from being killed, as white can't play either "A" nor "B" (since it'll lead into white's dead).

Black fail if he play at another point.



For example, if black play at Q18, white will answer at R18 and ecentually kill black's group.
