What do you mean? as in a forced capture of the opponents queen?
Three move opening . . .

mouwhaha
i have one faster than that.
1 e4 e5 2 f4 Qg5 3 fxg5
both games need black to help white to take queens, but mine is faster
heh, Laporte, good point.
I think there are numerous ways to win your opponent's queen early in the game, however, I am also positive that they all involve a huge blunder on his part.
What is the three move opening that takes the queen?
