International Checkers

This game is one of the most widespread checkers variants in the world. The game is played on 10x10 board and each player has 20 pieces (see the next picture):

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

Pawns move one space diagonally forward only, but can capture diagonally forward or backward. 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.
When a pawn reaches the last row, it promotes to a queen. However, if a pawn reaches the last row while jumping and can jump more pieces backwards, it does not promote and continues jumping as a pawn.
