Several extraneous "turbot" steps, but one is important in my solution.

Indeed - or a different m-wing if you prefer

Equivalent, but elephant gun move ! ...
| Quote: | Almost Remote Pairs : (34)R2C2 + Fin (7)r3c3-[3C3 AND (79)R1C3 (94)R3C1 4R2] : => r6c5<>34
[edit : corrected typo : I previously wrote 4C5 instead of 4R2 as the last SIS  ] Thanks, Danny, for checking !

Still playing with AURs...........
AUR(49)r45c47 External SIS: r3c4=4 and/or r6c5=9
AUR(49)r45c47[(9)r6c5=(4)r3c4]-(4=9)r3c1-(9=24)r45c1-(4=3)r6c2-r3c2=r2c3-(3=4)r2c5; this is a contradiction with r3c4=4. Thus r3c4<>4 and r6c5=9 to prevent the AUR(49) which completes the puzzle.

My Solver's Solution: useless basis for rating
| Code: | r79c49 <38> UR Type 1.2223 r7c4<>38
r2c2 2-String Kite <> 3 r6c5 extraneous
r26\c35 finned X-Wing <> 4 r45c3 extraneous
r6c1 2-String Kite (grouped) <> 4 r3c5 extraneous
c26r3 Skyscraper <> 7 r4c3,r5c4
r6 b1 turbot fish/ER <> 9 r3c5 extraneous
c35 X-Wing <> 9 r1c4
r46c36 <35> UR Type 6.2234 r4c3,r6c6<>3
BUG+1 = 4 r6c3

Too many typos, yesterday  Where was I  .... Here is the final corrected version of my stupidly written previous post.
Almost Remote Pairs : (34)R2C2 + Fin (7)r3c2-[3C2 AND 3B1 4R2] : => r6c5<>34
Thanks Danny for double ckecking  Regards, JC |
