One step.
Quote: | w-wing on 27 in r3c2 & r7c1 with grouped strong link 7 in r8c34:
(7)r8c3 = (7=2)r7c1,
(7)r8c4 - (7)r123c4 = (7)r3c6 - (7=2)r3c2.

I played a useless XY-Wing (793) and Hidden UR (78). The W-Wing (27) wasn't enough for me to finish but the Type 1 UR (17) was.

Marty,
Was your w-wing on 27 the same as I posted?
I looked at the puzzle again. The w-wing deletes the 2 in r2c1 and r7c2 and basics completed the job.

I think so, unless another one was available in boxes 17. Mine was connected by 7s in c6. |
