CALCULATE64.com a teenager’s contribution to chess world

Chess is one of the oldest board games in history. It has come a long way from being considered as a royal game played by nobles. Even during the pandemic when the sports world stood still, chess players found a way to continue their games online. In the midst of all the chaos a teenager from Haryana, Poorav Kadiyan created Calculate64.com. 

Calculate64.com offers an FIDE rating prediction system for players based on their ratings on different websites such as chess.com, lichess.com & chess24.com. Poorav’s entry to tech world was greatly inspired by Elon Musk.  He is an amateur chess player and is rated 1408 in FIDE rating. He also considers himself as a self taught data scientist, ML engineer and web developer. 

Being a chess player himself, Poorav was able to notice the shortcoming in Indian chess ecosystem and tried to come up with a solution to help part-time players ( those pursuing chess as a hobby ) to let them realize their potential by predicting their FIDE rating based on current ratings. He believes that his system will also help a player realize whether she/he is improving or not. 

The data used for the website is from public API’s of chess.com & lichess.com. Poorav boasts of having collected data of around three million players. It was also vital to remove the outlier’s which would have affected his algorithm. 

Algorithm:

He has built nine ML models to calculate FIDE rating for the respective three websites. The fields used for prediction are as follows:

  1. Ratings ( Blitz rating / Bullet rating / Rapid rating )
  2. Games played
  3. Federation
  4. Age
  5. Title
  6. Gender

He has also provided the facility of auto-filling the details by providing players’ respective IDs.

Some of the experts in the field who used Poorav’s product were quite satisfied. ‘Calculate64.com is a platform for young chess players who want to know their expected ELO rating without playing a FIDE tournament.
