Hi everyone, I just joined the forum and this is my first post.
I apologize for my bad English.
About this scheme, with W-Wing you can delete the number 1 even in r4c9.
You like to use unique rectangle? Numbre 6,7 in r3c89-r6c89 and r6c8=3.
Ciao
Gianni

Hi Gianni,

Welcome. No need to apologize for your English; it's perfectly clear.

As to the extra elimination from the W-Wing. Yes, that elimination can be made. Earl showed just the one elimination because it was enough to complete the puzzle.

Unique Rectangles (URs) are used by many players, but we don't see too many used on these puzzles.
