Home Youngest Grandmasters' CQs

It's my delight to list CQs of the youngest grandmasters (ELO rating over 2500) in history. CQ or chess quotient is a ratio of the player's rating to his/her age. For example, when Karjakin became the youngest Grandmaster ever, his CQ was about 199. Therefore, future youngest grandmaters will have CQs of at least 200. If you see an error in this list, please let me know. Paul
