Beginner Exercise 283 / Solution

Sub-page of BeginnerExercise283

This problem has two solutions, both leading to ko for life.

Solution 1  

The first solution is to jump down to the first line at B1.

Solution 2  

The second solution is to block with B1. Note that W2 is the only way to have a chance of killing the whole group, and thus we revert back to the first solution.

Solution 2 variant  

If W2 here, then B3 lives. (White gets to capture the marked stones in sente)


In both solutions, Black can choose to fight the ko with B5 instead. Here, a becomes a local ko threat for Black.
