Continuity mistake: When Bond takes off in the plane, we see - in one shot from Bond's view - the Cubans approaching. The background is a flat (English) countryside. In the next clip, we see a close-up of one of the Cubans. behind him are quite large hills/mountains. (00:04:55)
Revealing mistake: In the scene where Bond is trying to escape with his new Mini-Jet, he flies through a big hall. If you look carefully, you can see that the aeroplane which is supposed to be flying with its wings vertical is fastened to some kind of sustainer.
Continuity mistake: When Bond is fighting the twin on the top of the train, there is a carriage behind them, but when both of them fall off the train, the carriage has suddenly disappeared.
Factual error: Bond is given a tag in Spanish, but it shows the word Col., short for Colonel. It should read Coronel.
Revealing mistake: Near the end, When Bond is hanging onto the outside of Kamal's plane (first on the roof, then on the side), we see two instances of Roger Moore's stunt double. (02:04:13 - 02:05:10)
Revealing mistake: When Bond horseback rides towards the plane, Roger Moore is replaced by an obvious stunt man wearing red goggles. (02:02:50)
Continuity mistake: When Bond escapes from the train and drives away the number and position of the bullet holes changes between shots.
Revealing mistake: When Bond throws the baddie on the bed of steel spikes, the spikes bend revealing they're made of rubber (despite a crunch and a yell of pain being heard).
Revealing mistake: On top of the plane, Gobinda's stunt is noticeable because he has less of a beard.
Other mistake: Some of the shots of Kahn wrestling with the controls in the fight on the plane are reversed. The writing on the controls is backwards (eg RADAR JUNCTION BOX in the middle of the screen). (02:05:35)
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.
