It may be possible to create some interesting algorithms. The first  
problem to solve is that the optimal strategy is not stable since the  
best strategy of one voter depends on the decisions of other voters.  
That means that you maybe need to force the voters to use some  
strategy that is equally good for all but not optimal.

Yes. The opinion cycles are not really Condorcet specific but they  
occur in the preferences of a group irrespective of the election  
method. Condorcet just records them and then tries to make decisions  
including also the cyclic preferences in the decision making process.  
If you record the opinions of the voters using Range style ballots  
you will record the cycles too.

(Also normal Approval has this problem. If the preferences are  
A>B>C>A then the applied strategy (who approves whom) determines the  
winner. It is just that the voters themselves have to guess and  
decide on the election day what might be the best strategy for them.)
