Square rule for the win! In this puzzle, it creates numerous naked pairs and better. Other than that:
* Wing 2 G/: D4=2 (single in \); D6=8 (single in /)
* Here's my favorite part: J3-7 can't contain 2. If it did, both short compartments in cols 37 contained 2, but H2=2 (X). Same for 8 (H6).
* Settis 2, 8, 6
* (X) eliminations including squares, singles
* Setti 5
* Skewed wing on 3, \ and col 9: A6!=3
* Setti 7
* Here's where I run out of purely analytic tools. There's many 34 cells, so I suspect there's a UR hidden. Can't find one, though.
* CE/HC: E6!=9, otherwise F3=4 (via col 9) and F6=4
* Setti 3 / 2fish 1: G1=3
Done
