Meanwhile, elite classical tournament play began Thursday at the Quantbox Chennai Grandmasters in India.
Seven of the eight grandmasters hold a FIDE rating above 2700, with Abdusattorov competing there before traveling to Miami.
Youth Prodigies in the Spotlight
In individual developments, 12-year-old Supratit Banerjee secured his second International Master (IM) norm at an invitational in Sheffield.
He shared first place with Australia's Sam Chow after scoring 6.5/9. Banerjee ended a round with a queen sacrifice for checkmate against Lithuanian IM Gediminas Sarakauskas.
He needs one more norm and a published 2400+ rating to become one of the youngest IMs globally.
At the London ChessFest in Trafalgar Square, international prodigy matches concluded with mixed results for British youths.
Banerjee lost 0.5-1.5 to Argentina's Faustino Oro, while 11-year-old Bodhana Sivanandan defeated America's Megan Paragua 1.5-0.5.
