So here is the basic idea: My opponent has put one of my checkers on the bar and begins bearing off. A turn or two later, I get a lucky roll and move off the bar, putting one of my opponent's checkers on the bar. Assuming I already had my home area covered, I continue to roll until I start bearing off, when my opponent encounters some serious bad luck in the rolling department and isn't able to move his checker off the bar until his last turn. On my next roll I get lucky again, role doubles, and I'm done.
Since I have borne off all my checkers, and my opponent still has a checker in my home area, is this a backgammon, or has the fact that my opponent has borne off at least one checker make this only a cube? I was always taught that cube is only when the loser has all their checkers in their home area and have borne off at least one checker, however another answer here, as well as wikipedia seem to indicate otherwise.
