Algorithms, a documentary by Ian McDonald, takes a look at the relatively unknown world of blind chess players. Filmed over the course of four years, the documentary follows three talented children--Darpan, Sai Krishna and Anant—and one former champion player—Charudatta Jadhav—as they compete in chess tournaments and try to bring a champion title to India. The documentary opens in Mumbai at the National Team and Junior Blind Chess Championship in 2009, showing partially-blind and totally-blind people competing against each other.
