Here's another way to think about this: Suppose faction A makes some
assumptions
about the probability distributions of the 31 possible (strategically
sensible)
ways the B faction can vote and the 26 possible ways the C faction can vote.
For each of the A faction's 46 possible mixes (ranging from 45 A, 0 AB to
0 A, 45 AB), they could then calculate the expected utility and choose the
one mix that maximizes that expectation. This choice clearly will lower the
expected utilities of at least one of the B and C factions. But if the
"victim" faction anticipates this, they could gain by choosing a strategy
contrary to what the A faction assumed.
It reminds me of the stock market, where it often pays to use a contrarian
strategy. But that doesn't work when everybody is a contrarian, does it?
