[Eng] Irregular Anti-Knight Sudoku, by Salih Alan (WPF Sudoku Grand Prix 2024, round 6, puzzle 11) 

Absolutely lovely 👍

A really beautiful set-up with a very clear starting point as you can fill in all 4s from the get-go, then all the 2s, the 7/9 of the 9s. I really love deductions like the one you noted around the 20-minute mark in the video as they blow the puzzle wide open and from there, the puzzle solves trivially. @4:07, you can eliminate 1 from r4c1 as it breaks digit 1 in the region above.
