Longer route:
479 xyz pivot r7c5 sets r9c3 to 7, followed by 236 xy pivot r6c3
setting r8c9 to 6 - then basics.

I like hughwill's "Longer route"! I didn't spot it.
But I did spot:
(1) siamese twin to clement's xy wing 269, pivot in r9c7; and
(2) xy wing 268,
either of which also solves the puzzle.
Delightful stuff! |
