White to move and mate in two #732 - Twilight of Democracy

White to move and mate in two. The chess puzzle is published on Sundays, Tuesdays and Thursdays. It is customary for advanced players to wait till midnight ET before posting the full solution. Before then, they provide some stats about the solution (e.g., the number of distinct checkmate moves), help guide others, and sometimes post hints. But, there are no hard-and-fast rules, feel free to post comments as you please.

The Seductive Lure of AUTHORITARIANISM 

I happen to know that some of these ex friends are estranged from their children because of their political views. In a couple of cases, the estrangement is profound. One of my former friends, though deeply committed to a political party with an openly homophobic agenda, has a gay son. But that too is typical—these divides run through families as well as groups of friends. We have a neighbor near Chobielin whose parents listen to a pro government, Catholic conspiratorial radio station called Radio Maryja. They repeat its mantras, make its enemies their enemies. “I’ve lost my mother,” my neighbor told me. “She lives in another world.”
