NEW YORK (AP) — A Nigerian chess champion and child education advocate is attempting to play chess nonstop for 58 hours in New York City’s Times Square to break the global record for the longest chess marathon.

Tunde Onakoya, 29, hopes to raise $1 million for children’s education across Africa. He is playing against Shawn Martinez, an American chess champion, in line with Guinness World Record guidelines that any attempt to break the record must be made by two players who would play continuously for the entire duration.

Onakoya had played chess for 42 hours by 10:00 a.m. GMT on Friday. Support is growing online and at the scene, where a blend of African music is keeping onlookers and supporters entertained amid cheers and applause.

The current chess marathon record is 56 hours, 9 minutes and 37 seconds, achieved in 2018 by Hallvard Haug Flatebø and Sjur Ferkingstad, both from Norway.
