Hi all, I'm still with that position :

what would be white option here...should I play at 'a'... it's hard for me to find good continuations.... I'm a bit stuck with that one...
Any help welcome....

Yes, if black should have defended at a, then white playing there is a good idea. Black has so many cuts on the outside (s7, q7) he can't keep white contained. In fact black can even die himself in the corner now.

I looked at that, but what about this variation?


I really can't find a satisfying variation for black
