I'm still taken with the idea of duel between Alexy Karenin and Count Vronsky. What a great way to solve a problem...as long as you are Vronsky and feeling very confident of the outcome. Karenin, not so devoted to this type of problem solving. Number 1, he is a successful administrator so not accustomed to the ides of dueling as a form of negotiation. Number 2, by my reading he seems to be an out-of-shape old man, way past the physical prime that he may or may not have once enjoyed. Number 3, even though Karenin wants things to appear "proper", he really doesn't have much "fight" in him for Anna.
