A Nigerian chess champion is trying to break the world record for the longest chess marathon.

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.
