Definition given by author and inventor:

SneK Chess: The pieces are in following order: (Pawn) > King > Knight > Bishop > Rook > Queen.
If some piece is captured, the other one of the same color which is below it in the rank, transforms into a piece of the same kind as the captured one.
In case of option – the capturing side choose which piece will be transformed.
When a Pawn is captured – the Royal Piece of the same color (if exists) becoming a normal King.
 Here is the pattern:
When a Queen is captured – a Rook (or Royal Rook) of the same color (if exists on the board) becoming Queen.
When a Rook is captured – a Bishop (or Royal Bishop) of the same color (if exists on the board) becoming Rook.
When a Bishop is captured – a Knight (or Royal Knight) of the same color (if exists on the board) becoming Bishop.
When a Knight is captured – the King of the same color becoming a Royal Knight.
When a Pawn is captured – the Royal Piece of the same color (if exists) becoming a normal King.
