I assume the opponent loses two times the original cube value? (one times the value for dropping the game and one times the value for what is essentially a one game proposition of the drop?) For symmetry, you can add the following rule: If your opponent takes a cube you think is a drop, you pay him the original face value of the cube and he turns the cube once more (beavers). This is the same as offering an "extra" cube in a chouette (except the opponent can't redouble with one cube and hold the other). What about if your opponent doubles you and you think it isn't a double? If I'm thinking straight, you add a cube to the center and doubled cube you hold. There was a chouette variation mentioned here a while ago. I don't know if it was used in Boston over the summer (Albert? Can you fill in details or correct me where I'm wrong here?) but basically when a cube decision came up, everyone wrote down their decision. When the answers were revealed, if people disagreed then they had a five or ten game contract to play it as a prop. This is useful in several ways. If you make better cube decisions than the other players, you get extra profit by it. Since all of *us* are better at cube decisions than our opponents, we like it! <grin> But you get to see the position unfold five or ten times and see *why* it is a take or a drop. You probably want to have a slightly higher bankroll to point cost ratio for this kind of chouette than for a normal one. (You can't reduce your variance simply by following the captain on all cube decisions. And during any game you could be the only one who claims a particular cube is a take or a drop and hence have a five or ten game contract against everyone else for that position!) -michael j zehr   Did you find the information in this article useful?           Do you have any comments you'd like to add?
