How is knowing more about the environment and being properly equipped cheating, exactly? It just sounds that Amundsen was just a better explorer and leader, to me. He knew that the dogs were the best option and focused on them, instead of coming up with a ridiculous combination of dogs, ponies and motorised vehicles. The motor vehicles were not robust enough and Scott had to carry the horse food all the way. Scott also relied on his orders being followed to the letter, and he got properly screwed by his mates that completely ignored him and left him freeze to death. If you want to accuse Amundsen for anything, accuse him of designing an expedition with the sole purpose of reaching the pole first with only a bare minimum of science. Cheating, however, is a totally empty accusation.
