This is an absolute classic!

Written by Yes members Jon Anderson and Chris Squire, it was first included on 1971's The Yes Album and has appeared on several later albums. As with many progressive rock songs, the track consists of multiple distinct movements spliced together to form a cohesive longer work. The first movement, titled "Your Move", was released as a single. It became a top 40 hit in the United States, which helped the group build momentum. Later, album-oriented rock stations would frequently play the entire nearly seven-minute track, including both "Your Move" and the second movement titled "All Good People"; this version remains a staple of classic rock stations to today.

The tune uses chess as a lyrical metaphor for navigating interpersonal relationships, and contains several allusions to the music of John Lennon.
