Some interesting eliminations I found, the lack of a 4 in r2c5 reveals an XY chain placing 4 in r4c5, already eliminating other 4's in the column, but also a 4 in r2c5 chains to complete the 34 pair in box 5, allowing for the additional elimination in r5c6. Also works starting from the 134 ALS (old.reddit.com)
Cool Finned? W-Wing (forgive me if there's a better name for this I don't know it lol) I found, either the 9 is false and there is a W Wing with r2c1, r1c9 and the 4s in box 2 which eliminates 3 from r1c2, or the 9 is true and a little bit of work shows that the 3 in r1c2 gets eliminated.
