BQM 591

   

Hi SL,

My last game's opponent was quite creative and raised an seemingly interesting problem.

Descent

In the game White first had a rather good result as she created a long L group (Black can create a ten thousand year ko) and Black had a bothersome cutting point. However, she then answered poorly and died anyway.

Long L group

So the question is, how to avoid this sequence and get a better result ?

Block the other side

(This other crude play doesn't work either, White lives unconditionally.)

edit: Oh, actually it seems to lead to a ko.

Block the other side

White gets to take first but Black risks much less than in the usual ko.


Any better suggestions ?

Locally White cannot make two eyes after 1 below. So it depends on the surrounding position. Can White jump to 7 with 6 or attach at 9 with 8, threatening to connect to the outside?
