Puzzle 198 (Masyu (Full))

Masyu with a full loop constraint is ridiculously powerful.  A little too powerful, sometimes.  This grid is antisymmetric but there's still good logic to be had here!  (Though part of that is also due to the ... very large hole in the center of the grid.  Unfortunately, 169 is odd.)

Rules: Classic Masyu rules apply.  Additionally, the loop must pass through all cells.
