Calling all chess enthusiasts! As the biggest chess database in the world, Opening Master is thrilled to support Tunde Onakoya as he will start an extraordinary journey to break the Guinness World Record for the longest consecutive chess marathon! Starting April 17th at 10:00 am in Times Square, NYC, Tunde will take on all challengers in this New York City event.


Guinness World Record in Chess this April

But this isn't just about setting a new record; it's about making a meaningful impact. Tunde's mission goes beyond the chessboard – he's dedicating his marathon to raise awareness and support for millions of children worldwide who lack access to education. He firmly believes that chess can serve as a lifeline for these children, empowering them to see their own intelligence and unlocking a world of future opportunities. Him and Chess Slums in Africa together with Gift of Chess Foundation will make it happen. Why?

Now, we invite you to join Tunde in his noble cause. As he plays for an astonishing 58 hours straight, we humbly ask you to play alongside him, whether in person or in spirit. Together, we can make a difference. Come in person to Times Square if you can or connect with Tunde, Russel to help with the cause.

Our collective goal is to raise $1 million – a mission possible target, but one that is achievable with the support of people like you from all corners of the globe.

Let's come together, play with purpose, and make a real difference in the lives of countless children. Together, we can surpass our wildest expectations and create lasting change through the power of chess. Are you ready to be a part of something truly extraordinary?
