Kipling: When a player resigns a game with cube then the winner gets the number of the points of the cube multiply by the number of the points of the current position of the pieces of the losser (i.e. 1,2 or 3 points). When a player rejects an offer for doubling then the winner only gets the number of the points of the cube.

If you received that warning then the reason was you hadn´t taken any own piece out and all your pieces are not in the oponnets´s house (2 points) multiply by the cube (4 points). Are you sure the cube was at 2?

When you gained 2 points, then there are two possibilities: 2x1 or 1x2.
