Trying this potential DP on 78, which some call BUG Lite. There are five possibilities. The 1s in band 1 set r1c7<>1. The 1s in band 3 set r9c9<>1. So with r1c7 and r9c9=7, r7c7<>7=8. The other possibility is 5 in r2c5 which proves 8 in r8c5; r8c7<>8.

Also a simple W-Wing on 17 with SL 7 in r7; r1c2, r2c8<>1.

Note: the posted grid can be reduced via the 178 triple in r1.

Agree, it's fun, but don't hold your breath waiting for me to join the "some" group. I despise the term. Laughing Wink
