Timm(5k): I don't see a way for White to save his stones, sorry ;(

Herman: What if I told you the problem is white to play and kill... :)

Timm: This problem is vicious. At least I wasn't wrong with my last comment. :P Thanks Herman for the hint !


The problem becomes easy after noticing that this shape is dead.

Also dead!  

W1 and W3 remove eyes in sente, W5 prevents Black from connecting there to make a seki, also in sente, and W7 removes Black's second eye.
