Normal sudoku rules apply.
Digits in cages sum to the given total.
Additionally, every digit conforms to a chess move constraint; anti-king, anti-queen or anti-knight. Each constraint is used by at least two different digits and all digits that conform to the same constraint must form a consecutive set. Digits may be part of more than one set (eg. anti-queen digits also count as anti-king).
