Backgammon Rule variations

The Holland rule: This rule applies to match games and states that trailer can only double after both sides have played two rolls. It makes the free drop more valuable to the leader but generally just confuses the issue. The Jacoby rule: The Jacoby rule is used in money games. It states, that a gammon or backgammon may not be scored as such unless the cube has been passed and accepted. The purpose is to speed up play by eliminating long un-doubled games. Beaver and raccoon: In money play, if player A doubles, and player B believes that he is a favorite holding the cube, he may turn the cube an extra notch as he takes, and keep the cube on his own side. For example, if A makes an initial double to 2, B may, instead of taking the double and holding a 2 cube, say ``beaver'', turn the cube an extra notch to 4, and continue the game holding a 4 cube. If A believes that B's beaver was in error, some play that he may then ``raccoon'', turning the cube yet another notch (to 8 in the example). Cube ownership remains with B. B may then if he wishes turn the cube yet another notch, saying ``aardvark'', or ``otter'' or whatever silly animal name he prefers (the correct animal is a matter of controversy), and so forth.
