NF but took long. I spotted that 126 triple in row 6 but very late which was there frm the beginning of the puzzle and therefore the rem. 579 triple in the same row whose single 7 can be sorted out , what Georges is referring to. I remember getting 16 pair in row 7 at C2 and C4.

Rough puzzle. Working the column, however, the naked 7 is very much there in the bottom left corner of block 6.. Then everything goes well.

This puzzle also warned me again don't underrated any puzzle, l confused and took 28 min, more small no's in all cells, then it solved. I saw vedio but what no's I needed you got easily, actually under 10 min puzzle this one. I started second time, col 7, box4, then col 2, after then UR 56s in R4&8, C5&6, 8 in r4c5 made it 10¹½ min. If software users can solve 8 or 9 min. Second solve doesn't comes in account. I confused different way and you confused different way, so the puzzle win to make confuse. Nice puzzle thanks.
