It turned out our Jamaican friends set their board differently, with the Mason line at the bottom right corner. Since they do not record their games yet I propose they mirror the existing Pool Checkers notation - this way all games, American or Jamaican style, are recorded and re-played exactly the same way, no matter how the board is set. This would help them greatly to absorb the existing information and keep the same "Pool Checkers Language" in all countries.
To demonstrate I flipped all diagrams in the Jamaican Contest
to make them look Jamaican style. Just print and distribute to your friends!
