World SUDOKU Grand Prix 2015

Did you come to this solution, or did you get stuck before? If so, please post a picture of it.

I was stuck in this situation by a rickshaw puller.

I'll try to post a picture again :)

The answer is in the picture. I colored 2 squares yellow, where 2 and 7 must fit. Once you understand why 2 and 7 must be there, you can then put the number 1, because it cannot be put anywhere else in the second column.

Oh yes. Maybe this option is still a bit complicated for me :) How did I not notice that box there, I even wrote out the options, etc. Now, after the hint, the solution is of course nice. Many thanks, Tiit. riksman
