White thinks about ko  

Charles White 1 here might cause trouble.

White thinks about ko  

Considering the effect of White c, White 3 here is interesting. If Black a, White b and White would welcome a ko fight.

Double-digit kyu sequence  
Is this why B2 is not possible here?
Black to play  
It seems B6 needs to be played elsewhere...


Charles In this case, White is likely to give up one stone. This creates a dangerous situation for Black, because the exchange black+circle/W1 is a loss for him. Up to 5 Black wants to cut White on the edge, and also fix the cutting point at a.

Variation (continued)  

There is a ko here at B7: suppose White doesn't bother taking it after B1, B3. Then the cut at a is a problem for Black, so I think B5 will be played (there are several difficult issues here). After W8, Black may still try to kill everything, but it has become very hard, no? He has real shortage of liberties on the upper group.

If White can find the correct way to play ko threats such as b and c, Black may make a large loss.
