Back by unpopular demand! The second puzzle in the indexing checkerboard series.

- Normal 8x8 sudoku rules apply (without regions).

- Row indexers: Blue cells are row-indexing cells. A digit in a blue cell gives the placement of that cell's row number in its column (see diagram below for example).

- Column indexers: Red cells are column-indexing cells. A digit in a red cell gives the placement of that cell's column number in its row (see diagram below for example).

- Anti-Knight: Cells separated by a knight's move in chess cannot contain the same digit.

- Cells with a grey square contain an even digit. Cells with a grey circle contain an odd digit.
