resolve the ko
Keywords: Ko
There are basically two ways to resolve a ko:
1. Connection
It is now more profitable to capture the marked black stone to end the ko.
kb: I vote for one more...
3. Extend
If one or more of are not important, White can play this way, especially if Black retaking the ko is not sente, and depending on other situations around the ko.
Tas: Doesn't that just mean that the ko was not important in the first place. White could just play w1 right away.
