The strongest opening rolls are the ones that let you make a new point, because owning points builds blocks and keeps your checkers safe. Rolls that naturally form an inner-board or bar point are generally considered the best openings, since a made point both blocks the opponent and avoids leaving a blot. Other opening rolls are better played by splitting your back checkers or running one out, depending on the numbers. There is no roll that forces a mistake, but each has a widely accepted best play. As a beginner, prioritise making points when a roll allows it, and avoid leaving unnecessary blots early.
