Continuity mistake: When Bond is about to fly through the hangar, the soldiers are running away. In the immediate next angle they're standing still and the colonel is commanding them to run.
Continuity mistake: When Bond is about to take-off, there's a brief shot of the plane speeding up. It is obviously a different runway because a) the trees on the side have disappeared, and b) the road swaps from clean to filled with skid marks.
Continuity mistake: When Bond places the bomb inside the radar he is slightly facing backwards and twisting his arm, but a shot later he is perfectly positioned in a much more comfortable position.
Continuity mistake: During the pre-credits Bond enters a military base, knocks down a soldier and places his suitcase on a table. The position of the suitcase changes between shots.
Continuity mistake: At the beginning of the film, Bond takes off with his plane. When he is about to take off you can see the wheels under the plane, but in the next shot the wheels are gone.
Continuity mistake: During the fight on the roof of the train, the scenery in the background changes dramatically between shots. Especially when the surviving knife artist climbs up on the roof. There we are in a dense forest, and when we cut to Bond, we are on an open field.
Answer: Bond (taking over for the Major) had 1 piece on point 2, 1 piece on point 3, and 2 pieces on point 6. Rolling doubles in Backgammon means you get to make 4 moves instead of just 2, so he was able to remove all 4 pieces. If you have a piece on point 2, you don't have to roll a 2 to remove it. Anything higher than a 2 can be used to remove the piece. Kahn even says Bond has to roll a double 6 in order to win, which he does.
