In this 17-voter election, A is both the IRV and the Condorcet winner. (Pairwise victories: A beats B 11-6; A beats C 9-8.)
If the C>B>A voters in the bottom row decide to "betray their favorite" C by voting B>C>A instead, then IRV elects B. (A is eliminated then B wins 9-to-8 over C). That, from the point of view of these voters, was an improvement, i.e. the favorite-betrayal worked.
