| Blue's starting position, without opposition | |||||
Problem 1: ..From his starting position (diagrammed above), how can Blue reach the (previously shown) outer prime formation in four rolls? Try it!

| Starting position of backgammon | |||||
Problem 2: ..Same as problem 1, except Blue's first roll must be a non-doublet, and he cannot move any roll portion to his 19pt, 17pt or 12pt (i.e., the points White occupies -- she does not move).
Problem 3: ..Blue has to reach the same formation, but it's interactive: WHITE starts, and each side plays FOUR moves perfectly (according to XGR++ evaluation, money game).
Problem 4: ..In addition: It is never proper to turn the cube, yet in the final position one side leads the other by more than 45 pips.
What is a workable sequence?
