None, and in fact, I think that between two players who understand the mathematics of this game, no one should ever have any edge. The reason you can win so often is that most players are fish because they pick paper way too much. A mixed random strategy of 70% scissors, 15% rock, and 15% paper should be able to crush 90% of the players on that site.
