After the messy basics, I found a flightless xy-wing(57-4) plus transport.

(4=7)r7c8-(7=5)r7c3-(5=4)r4c3-r5c1=4r7c1 => -4r7c7

For variation, here is an almost Sue de Coq.....

Almost Sue de Coq (13579)r123c9 ab=35r9c9, cd=79r2c8, e=1r3c9, fin=7r9c9

Almost Element: 7r9c9-(7=4)r7c8-(4=1)r8c8 => -1r8c9

Structure: Sue de Coq (13579)r123c9 ab=35r9c9, cd=79r2c8, e=1r3c9 => -1r8c9 (Plus other deletions which are not necessary to complete puzzle.)

Finned x-wing on 7 in row 29; r13c9<>7.

As best I can see, this move is enough to finish it.

Thanks Ted. I didn't dare make my post until I did it on Draw/Play to confirm what I did on P&P.
