From the archives
Named for the 19th-century Russian master Alexander Petrov, the Petrov spent a century labeled 'drawish' — then Fabiano Caruana brought it to the 2018 World Championship, where it answered both of Magnus Carlsen's 1.e4 games and drew both. All twelve classical games were drawn and the title went to a rapid tiebreak. Symmetry, it turns out, is a weapon too.
