Blindfolded Chess: The Return of the Chess Line Sudoku Variant is Magnificent

Today's Puzzle:

We're back to a personal favourite of mine, the Chess Line invented by gdc. This time with an exceptionally well-constructed puzzle from SamuPiano.

My advice would be to use the fog to its fullest as it's really your shepherd in this puzzle.

Rules:

Normal sudoku rules apply.

Fog: The grid is partially covered in fog. Entering correct digits will clear some fog in the grid.

Chess lines: All gray lines have an image of a chess piece in the leftmost cell of the topmost row containing the line. Adjacent digits along the line must be related on a standard 3x3 keypad by the standard movement of this chess piece. No castling, pawn capture, double advance or promotion are permitted. In other words, pawns may only move one space vertically at a time. (2-5-8-5 could be a valid pawn line.) Lines cannot branch or share cells.

Kropki: Digits across a black dot must be in a 2:1 ratio.

XV: Digits separated by an X must sum to ten.

Not all dots or Xs are given.
