Fixes bug where pawn can only attack black pieces
Sjadam is a mixture of chess and checkers, combining the best from both worlds.
Rules:
- You may start of your move with either a sjadam jump or a legal chess move.
- Once you do a chess move (or rightclick on a tile), your turn ends.
- The sjadam jump is valid if you can jump over a piece onto an empty field. It can be any direction; north/south, west/east or sideways.
- You may jump over as many of your own pieces as you like, but only over one opponent piece each turn.
- You may do a chess move whenever you feel like it.
- If any piece except the king makes it all the way to the opponents side, it evolves into a queen.
