Achievements are the ultimate goal of Chess. Created by the developers of Chess at its launch, the full list is unknown as many are hidden. No one has yet gotten all of the achievements due to difficult conditions (for example, Perfect Day requires the player to convert all of their pawns into Queens without losing any pieces), secret conditions (no one is yet sure how to earn French and Indian War, e.g.), disputed records (doubt has been cast upon the validity of Billy Mitchell's record-breaking Chess speedrun video), and hidden achievements (there are at least sixty achievements that have so far not been publicly revealed).
Bobby Fischer currently holds the record for highest Chess Gamerscore.
