Sudoku GP 8 - Liar Killer Sudoku explained

Hello all,

I hope you enjoyed the last round of the Sudoku GP 2020. Nikola and I did our best to ensure that the liar variants would not be too hard (actually most of the puzzles that made it to the final cut were originally meant to be harder), but I figured the Liar Killer may still have given trouble to some, and they could use a little help to get it done. To this end I published a video in which I go through the intended solving path - in particular I explain the opening step I had in mind. You can watch it here: https://youtu.be/v1wiXmJ7pAQ

Also, congratulations to Kota, Kuba and Tiit for securing a podium spot. Cheers!
