Path: GoProverbs · Prev: LearnTheEyestealingTesuji · Next: FourDieButSixLive Path: LifeAndDeath · Prev: SquareNineInTheCorner · Next: FourDieButSixLive Six stones in a row on the second row die, but eight stones on a row live. Seven stones in a row depends on sente. This applies to the life of a group which has no eyes and which has a solid row of connected stones on the second line. As long as the group is enclosed, the number of external liberties are irrelevant.
Even if black has sente, white will end up with a straight-four big eye, which is alive. (the two 'x's are miai.)
With seven stones and sente, white also ends up with a straight-four big eye, which is alive. (the two 'x's are miai.)
With seven stones and gote, white ends up with a straight-three big eye. After 5 white is dead.
With six stones, even with sente, white ends up with a straight-three big eye. After 4 white is dead. --MortenPahle But there is a condition that white will live.
Under the condition that white have stones in a and b, if white plays first, white will live. If black plays first, white will live with a Ko fight.
