Beginner Exercise 47 Solution
Difficulty: Beginner
Keywords: Problem
![[Diagram]](../../diagrams/43/365dcaf87b47471e853697107e40ab85.png) | White first to create a ko. |
splice: creates a ko. Black cannot respond at a because of damezumari. Any response that does not threaten (except b, discussed below) will capture the two black stones at the right in a snapback (White b, Black a, White b).

connects and sets up the ko. Black must take the ko, lose the four stones at the bottom, or connect them and lose the whole group. Ko it is :0
![[Diagram]](../../diagrams/6/7a871fb592edf7490ce05d62874c89cd.png) | Possible too |
Straightforward ko sequence.
har1s?: i don't see any profit for white, black still create 2 eyes anyway. ????
HolIgor: At the last diagram white threatens to capture 4 black stones and black cannot connect. Black cannot capture back because of ko rule. The only solution is to make a large threat elsewhere, which sets up ko. Black is better of at the second diagram because white has to look for a ko-threat first.
