BQM 599

Are the groups halfway between the L group and the L+1 groups dead?

I'm guessing yes, because it seems to me that the 0.5 intersection and the adjacent intersection along the board edge are miai to make it effectively an L group.

The L Group  

First L+1 Group  

Second L+1 Group  

First L+0.5 Group  

Second L+0.5 Group  

Dieter: indeed but ...

First big L+0.5 Group  

If the circled stone is one further, the L+0,5 group can live by capture three to make an eye

Second big L+0.5 Group  

Same here

Double big L+0.5 Group  

Interestingly, a group with a double big empty wing can still be killed.
