This is a position reached after white's 7th move during the 7th, 11th, and 15th games of the Spassky-Fischer match in 1972. It seems reasonable to use this position as a benchmark simply because it occurred 3 times during a single world championship match.
It is called the Najdorf Variation of the Sicilian Defence, named after the Polish-Argentinian Grandmaster Miguel Najdorf. Prior to this match, Bobby Fischer (black) had never lost with it. The Sicilian Defence is one of Black's most popular responses to 1. e4. Today it is known as ECO B96.
