                  Look, the fastest way to win most of the time is to ask questions that remove half the characters each turn, but once your opponent learns to ask the exact questions that you do, you will only win 50%. For 40 characters you will win in 5 moves: 20-10-5-3(or 2)-1. I don't know if your strategy always goes for 50%, but it should.

                      The binary search algorithm has a broad test, and for ordered data is the fastest search, so I am guessing broad. Let's see.

                                          I used to memorize everything everybody asked everyone at Clue and always won since you have to ask a question (a person, an object and a room) using at least one card you have. I never lost a game of Clue and no one wanted to play with me after a while. It took me about 2 to 4 turns (playing with 2 other people) to win.

With this strategy you AREN'T asking two questions because you don't necessarily know what part of the question your opponent has.. it's not like they say yes, my person has glasses.. they just say yes or no. Yeah it might seem unfair but the game is just chance anyways. With this strategy it gives more meaning to the game because it actually requires thinking.
