FusekiExercise6/Solution by LZ

LZ's choices  

The original post asked to choose between a, b, or c, and favored b, since it makes the traditional "ideal" extension from an enclosure.

However, there is still an asymmetric position in the upper left corner, asking for an approach at d or e, which is what LZ would do. Her 3rd choice is the unexpected f, breaking up the lower side.

Feeding the solution  

Not that the suggested solution is that much worse. LZ evaluates this position at 60-40 for White. If Black had approached the upper left, he'd be 3,5% better off.
