QUINCUNCES: the two groups of five cells (indicated by the circles) are clones of each other, containing the same digits in the same relative positions.
Otherwise standard Sudoku rules apply.

I love your Shading/Anti-Knight puzzles. Thank you very much.
This one was on the harder side for me. But the logic is nice and exciting.

Thanks ATK - had to think a bit differently for that one. Nice the way the two sets of five interacted. Good to have a fresh take on the rule set.
