I forgot where I got that puzzle. Probably recent sudoku.com. But anyway, I give up trying to solve it.

If I guess a 1 at r2c6, it solves immediately.

How can I proceed without guessing?

Look where 2 can go in blocks 2 and 8, it allows an elimination in block 5. Then do the same for 8 in blocks 4 and 6.

At first, I thought you were mistaken, but I kept at it and finally found that I had a pencilmarks error which led to that solution not being possible.

Thanks! Wouldn't have found it without you!
