Characteristically Simen goes for the sharpest solution.
The name 'Stonewall' has tricked many white players. In Simen's hands, the wall is actually extremely mobile.

White tries to fend off the attack by tactical means. It backfires badly but it seems White had serious problems anyway.
This looks convincing, but I'd have to consult Fritz to be entirely sure.
