New game mode "Random Positions" available !
Basic chess now available ! (Not compatible with the "Reinforcements" mode).
Bug fixes:
-The game now ends in a draw if checkmate is impossible with the remaining pieces.
-If a piece is trapped, it can no longer checkmate the king.
-Fixed problem that brought a piece on a trap when the trap was not on its trajectory.
-If a piece is protecting the king against a queen, rook or bishop, it can now move freely between the threatening piece and the king.
-Sometimes the AI did not play its turn, this should not happen anymore.
