In one-on-one negotiations, Metternich was a chess player on the grand-master level. With Taticheff as with so many others, he first lowered his opponent’s suspicions by playing the foppish, even dim-witted aristocrat. Next he drew out the negotiations, miring them in abstract, legalistic discussions. That made him seem even more stupid, further misleading Taticheff but also confusing and irritating him. A confused and riled negotiator is prone to make mistakes—such as reveal too much about what he is after, always a fatal error.
