Beginner Exercise 142 / Attempts

Right answer? White has a ko to live.  

unkx80: I would say, White's play is sub-optimal. But you are almost there already. =)

Malweth: I see, I think... White would do better to save the E19 group.

Better play?  

W need only ignore a single threat to play a, winning the ko. No need to connect to the other side, they're already alive. B has a direct ko, but has to make the first threat.

On second thought, why not take , it's extra points...
