Status ?  

We can consider this shape to be a weak L+2-group - the weakness being the absent stone at a. On top of that, Black has black+circle in place. What would be the status of this group ?

Status ?  

It takes little to realize that White can live by playing at W1 or a. The real question is whether Black can kill.

From the outside  

Occupying the weak point leads nowhere. White lives easily: it looks like W2 is the vital point.

Attack at 1-2  

The attack at this point amounts to failure.

Attack at 2-2  

After W6, it is pointless to continue with Black a - White b. In fact, the marked point provides the extra liberty for the group to be alive
