Okay, I am the inventor of an official new backgammon variant.
Its called Czuch Backgammon.... It is the same as a normanl backgammon game, except that once a game becomes a race, whomever is in the lead is declared the winner. In the event that it takes only one die to make the game a race, the other die is not used. (doubling cube rules to follow soon)
grenv: Yeah, so you like the cube because it takes some of the luck out of the game, yet you think luck is part of the game so any game that eliminates some luck is silly? I think it would make a nice variant, and the more I have thought about it, there would be some added strategies not present in a traditional backgammon game!
Czuch Czuckers: I also think that your proposal deserves to be tried. It is true that the doubling cube adds skill even to straight races, but it is not very difficult to learn the basic cubing strategy in races, so when both players know it there is again few room for errors and it is 99% luck all the same. What you would really like to test in your variant is the type of positions where contact is almost broken, for instance both sides still hold their midpoint. Those positions would turn from quiet almost-race positions to extremely volatile. The only thing I don't like about your proposal is that for playing over the board, it requires taking the exact pipcount into account while playing, which is tedious. Online, having the pipcount shown would be a must.
Czuch Czuckers: Actually there are good techniques for counting pips across the board using patterns and a little math. Do a search and you'll find a few.
