# RTG Problem 59 / Solution

Sub-page of RTGProblem59

While the eye space after capture looks rather different from the other 17 and 18 stone capture constructions at largest capture that still can't live, this problem share a similar structure: the eye space can be broken down into two parts, where it is impossible to make even one eye in one of the parts and the other part gives only one eye. Interestingly, this problem isn't very trivial.

Solution

Obviously, to capture all White stones, Black must start with . captures 18 stones...

Solution

The placement of makes and miai, thereby denying White an eye on the upper edge. We shall see that despite , White has only one eye in the center.

Solution

If connects, then kills. and are miai, and after a and b are miai as well.

Solution

Making an eye at here reverts to the previous variation.

Solution

connecting here will not live either. If at a, then makes the same placement.
