Vasily Smyslov, 1921-2010, an Appreciation — It is not surprising that accolades have poured in from all over the world on the death of Vasily Smyslov, the seventh world chess champion. Though Smyslov was the titleholder for only a year, he was among the world’s best chess players for decades and his games had a certain clarity to them that was widely admired.
