They each belong in a cell a knight's-move from their current position.
Otherwise, normal Sudoku rules apply
Solution code: row 5 + row 6

interesting idea for a puzzle. wish i had known that each false given had a unique correct cell without looking in the comments; that would have been helpful.

That was very difficult, but greatly satisfying!.. Thank you @ATK for setting this original puzzle!..

Glad you liked it @Chelo. I should probably make some others with this rule set. -- ATK

No, that would be forbidden.

zlotnieo (and anyone else confused, as I was), I solved it assuming that:
1. If a clue is in a cell, then that digit CANNOT be in that cell, even if otherwise allowed.
2. Each clue points to a unique correct digit - so in your example, no they could not both point to the same digit in r4c7.

Can the givens' real positions overlap, e.g. could the given 4s in r3c5 and r2c8 both belong in r4c7?
