Even when worded in terms of preventing successful offensive strategy rather than protecting the CW's win, strong 1st Choice is probably unattainable for any 1-balloting method. At least for Condorcet(EM). I don't know about Schulze. But Condorcet(EM) meets it unless impossibly well-informed offensive strategy is used in a many-candidate election. So that method _for all practical_ purposes meets that criterion. That can't be said of Margins or IRO. Mike
