Now, using Bernice as an example.... lets say people start to play 2 when she is in last place because she is known to play 1 in that situation. Now maybe she can play 10 or 200 for example and sucker someone else into the pond instead of herself. Thats how playing a 1 in this game may end up helping you in another game down the road! Also it will mess up how the person in first place will play the end game as well. If they can no longer predict that everyone else will play 501 or higher, it obviously makes their job that much harder.
