Kyu Exercise 13 Solution
Keywords: Problem
Prelude
![[Diagram]](../../diagrams/35/2ce3060f2e2c247c94aa4d5dc2b758f4.png) | Order matters. |
The order of the throw-ins and is very important. If Black captures with , White descends with .
![[Diagram]](../../diagrams/7/973872c5bcd6e9c78fdabb44651c9376.png) | Connect-and-die. |
Black has three points to connect: , a, b. But the chain has only two liberties.
![[Diagram]](../../diagrams/24/6b5749cef6daffd67d4ab51f1adb9d16.png) | Snapback. |
If connects, captures the chain in a snapback.
But this is not yet the solution.
Solution

Now, presenting the actual solution.
![[Diagram]](../../diagrams/26/ff8993325592ba37292c93bf5d45df19.png) | Strongest resistance. |
The strongest resistance by Black is , and is the only way to salvage the situation. This is the solution, which is a direct ko. If Black wins this ko, he simply captures at a, and the white chain on the left is captured cleanly.
![[Diagram]](../../diagrams/13/c8ee7e8688d70390d741f4e39ea56889.png) | Local ko threat |
There is a local ko threat at .
Failure
![[Diagram]](../../diagrams/33/59391daec8138911e46051c77a3559fe.png) | Failure. |
The hane at is a failure. As is a necessary approach move, Black connects at just in time, so there is no connect-and-die.
![[Diagram]](../../diagrams/39/7a987d75a7efb8b216358fbde0dde29d.png) | Failure. |
If in the solution diagram makes a throw-in on the left side first, then can connect. The result is the same as the previous failure diagram.
