This puzzle is inspired by Knight Line and similar puzzles. I decided to extend the concept to use all the chess pieces. Thanks to Skunkworks for testing and especially to Chameleon for creating a PuzzleTV version of this puzzle.

• Normal Sudoku rules apply.
• Adjacent digits on a line must form a valid chess move by the indicated piece on a 3x3 numpad.
• For example, a 1 on a knight line may only have the numbers 6 and 8 next to it so 6-1-8-1 would be valid.
• Pawns can only move exactly one cell up or one cell down, so 2-5-8-5 would be a valid pawn line.

Examples

Here are illustrations of the possible neighbors on a bishop (♗) and knight (♘) line. A 5 on a bishop (♗) line can connect to every other odd digit. 1 and 9 can also be next to each other on a bishop (♗) line since bishops (♗) can move multiple squares along a diagonal. A 2 on a bishop (♗) line can connect to 4 or 6. 5 can never be on a knight (♘) line and a knight (♘) always has exactly 2 possible neighbors on a line. A longer run for a knight (♘) line would be 1-8-3-4-9-2-7-6-1.
