Thanks, Kevin. It was a comment of yours that made me realize that burial
punishment (via chain climbing) was not enough ... but of course, looking
away and pretending the burier was probably sincere ... that is no good
So a sincerity check is natural ... if the sincere ballots contradict the
strategic ballots, then in this case you have both detection and correction.
Perhaps we could forget Chain Climbing and just use the sincerity check on
the weakest defeat that was critical in determining the winner.
