I just thought I'd mention that there's a hidden 46 pair in box 6 which locks the 1's in row 6 of box 5 which eliminates the 1's from r4c46 but it didn't make any difference. I still had to use Clement's XY wing. I also noticed that the 123 XYZ wing with pivot at r4c2 doesn't solve it. And the 46 UR type 1 in columns 7 and 8 doesn't solve it either.

I'll take advantage of this opportunity to be my usual curmudgeonly self and say that there's a 138 naked triple in box 6. Laughing
