[EM] A more general chicken dilemma

[Kristofer Munsterhjelm]

I've been investigating different criteria lately, and the chicken 
dilemma criterion seems to apply to very few elections in general (as a 
proportion of the number of elections possible with a given number of 
voters).

So I was wondering if the following would be a good generalization:

The following is required for an election to be applicable:
	- There are three candidates and three factions, call them A, B, and C. 
Each faction prefers its corresponding candidate to everybody else (but 
may rank others coequal top based on the method, e.g. if it's Approval).
	- The number of C-voters who prefer A to B is equal to the number who 
prefer B to A (i.e. they have no meaningful preference between the two).
	- If the A-voters and B-voters express a full ballot, then A wins.

Then for every applicable election:
	- If the B-voters truncate above A, then B must not win, otherwise the 
criterion is failed.

What do you think?
