A Game created by me, my room mates

It was a totally dark day. Raining outside completely and no power supply. It was the time perfect to play something and a new game emerged out of our creativity.

1. There should be 4 players to play this game. A,B,C,D
2. They are divided into 2 teams , say A,C are team1 and B,D are team2.
3. A,B,C,D sit in clockwise direction in the same order.
4. In the first TURN, A has to choose some word X and conveys this secretly to B.
5. B then gets the chance and can choose any word Y , either directly related to X or it can be anything random. Lets say X is "Mango". B can choose Y as "Apple" , "Tendulkar" or "Titanic" or anything.
6. Now B has to ask a question. This question is of the form "X or Y" or "Y or X" depending on his interest. Nothing more is allowed in the question.
7. Objective of C is to guess what his team mate A would have chosen.
Note: You must remember that it was B who had the luxury of choosing Y and questioning. So B has to be smart enough to keep the other option Y in such a way that C cannot easily make out what A has chosen just listening at the question.
8. Once C has guessed, D has to guess the answer. D has to guess the choice which his parter B has chosen.
9. Once C and D have guessed , the answers are announced. (A,C) would get 1 point on a correct guess and (B,D) would guess 0. (A,C) would get 0 points if incorrect and (B,D) would get -1.
10. Now the game goes to TURN 2 the same steps are followed with B telling the word to C and D guessing it followed by A.
