Zugzwang by Ronan Bennett (2007)
In German, zugzwang is a term used in chess to describe a position in which a player is reduced to a state of utter helplessness. The action is set in pre-Revolutionary Russia: St. Petersburg, 1914. Dr. Otto Spethmann is a psychiatrist who is drawn into a murderous intrigue and an intriguing romance. It’s a deadly game, but good read.
