Portuguese Checkers

Portuguese Checkers (also known as Spanish Checkers with rotated board) variant is played on 8x8 board with 12 pieces of each player and the A1 square is white, not black (see the picture).

There are several specific rules, regarding piece moving and capturing:

Pawns move one space diagonally forward only and can capture diagonally forward only too. Queens (promoted pieces) move any number of spaces diagonally forward or backward, and can capture any number of spaces diagonally forward or backward as well.
Jumped pieces are removed from the board after the full move is performed and every enemy piece can be jumped over only once.
It is mandatory to capture as many pieces (as one multi-jump) as possible.
If a position allows 2 or more longest captures, it is compulsory to choose the one which captures the maximum amount of queens.
