A ko.  

I see a very bad ko for black. -Mihoda

B wins the ko.[1]  
Where to play for W.  

A white play at W1 seems best. -Mihoda

Five ko threats are left over.  

B1, B3, B5, B7 & B9 are ko threats later on, so look for B to start ko. - Mihoda


Black wins ko (better)  

B5 @ black+circle

Bill: Black has a better way to win the ko. B1 puts the white+circle stones in atari. If White takes the ko with W2, B3 says atari again, and White cannot connect at black+circle because of damezumari (connect and die). After W4 B5 takes the white+circle stones.

Local ko threat  

Bill: That being the case, W1 is a local ko threat for White. If B2 connects @ W3, W3 @ B2 kills.

Note that Black has some local ko threats starting at a.
