Pawns can make linear moves and all pieces can jump only orthogonally.
(*) It is mandatory to capture as many pieces (as one multi-jump) as possible.
(**) It is mandatory to capture the maximum possible amount of promoted pieces.
(***) It is mandatory to capture with a promoted piece if possible.
This checkers variant is played on 8x8 board with only 8 pieces of each player (see the picture).
The rules are similar to Czech Checkers with these differences:
A queen can make long jumps (over more empty squares) but must land just on the next square after the captured piece.
A queen does not have a jumping preference (if a jump can be done with a queen and a pawn at the same time, any of these pieces can be chosen).
