As a rule, so-called "positional" sacrifices are considered more difficult, and therefore more praise-worthy, than those which are based exclusively on an exact calculation of tactical possibilities.”

20.Rad1?? [A miscalculation. White probably thought that the knight on d4 could not move due to the mate threat on g7. Instead, he should have played:]
