You helped me cut my hard solve times in half, so when I was still lost at 45 minutes I knew I was missing something. Sure enough, I was blind to that 49 pair at the top for some reason. Once I had that it was smooth sailing. Thanks for the thorough walkthrough!
The earlier corner marked 2s in that box demanded that the 2 be in one of two positions in that box. Therefore, when one of them was eliminated by placing the 2 in column nine, that left only one place for the 2 in that box. Not a naked 2 in my opinion because of you examine the cell alone a 6 could be there but for the earlier corner marked 2s. I hope that helps.

For me, definitely the "trick" was to find those two pairs in r3. From there on, smooth sailing. Nicely done! Thanks.
That was very helpful. Thank you. My attempt was - um - messy. Good to see someone who knows what he's doing.
Nice puzzle, thanks rangsk!
Immediately after placing the 7 in box 3 I saw the hidden single 7 in row 4 column 9 and had no issues after that
This one took me 15 minutes, but I got distracted in the middle so not sure my exact time.
I don’t know how you got naked 2 in row 1, column 7.
6 was also option unless I am missing something. Thanks.

When I first started watching Rangsk I had trouble following when he moved quickly but after a while it all made sense. Good luck!
Sorry, now, I saw it. Thanks
Boys, it's a wave of scan every single cell-puzzles
Should be over in a couple of days
12:40 to solve.

I did it in 22:06
difficult to find those hidden tricks. Used tools to generate all possible candidates at very beginning, then it is quite simple to find those.
