You can use a finned fish on [2] in cols 1 and 7 to eliminate [2] from r2c2.
You can use an XY wing to eliminate [5] from r2c1.

Thanks for the help. I was over 2 hrs into this mess.
I had found all the x-wings, and I used the UR to eliminate 5 from R7C4, R7C6, and R8C3, since R7C4 or C6 must be 2. However, sin ... |

Hi, new here. I've been trying all the VH puzzles on the site, and have gotten pretty good at X-wing, XY-wing, swordfish, etc.
But todays LA Times puzzle is a real stumper. For starters, the grad ... |
