 *-----------------------------------------------------------*

(7=8)r6c9-AUR(39)r46c15[8r6c1=2r4c5]-(2=9)r4c8-(9=7)r1c8; -7r1c9

Another approach to the same deletion is an
axy-wing(29-7)r4c8+r1c8|r5c9=8r5c9-(8-7)r6c9; -7r1c9

The 7's in block 9 made this interesting. I still might have a problem with the notation.

 *-----------------------------------------------------------*
9r4c8=(9-87)r5c7=7r79c7-r79c8=7r1c8 => -9r1c8; stte

if r4c8 is not 9 then r1c8 is 7

I had no difficulty following your notation but do not understand your intent by including digit "8". Why not just

9r4c8=(9-7)r5c7=r79c7-r79c8=7r1c8 => -9r1c8

You are right. I had it right then let my head tell be different. It is strange how you think sometimes. Thanks for the help.
