For my father's birthday I wanted to set a sudoku with his birthyear and his new age, however I ended up setting three puzzles instead. They all share the same ruleset, and there is a slight increase in difficulty. This is the second puzzle. (links to one and three)

Enjoy! :-)

Rules:

Normal sudoku rules apply.

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

Non-consecutive: Orthogonally adjacent cells cannot contain consecutive digits.
