During this checkers competition, Wiersma had an opportunity to meet with and play against Senegalese Grandmaster, Baba Sy, after ten years had passed since Harm faced Baba Sy as a checkers opponent in 1963.

There was also time for a cultural exchange as Baba Sy displayed and sold African necklaces from his home country. From 1970 through to 1977, Harm faced the Senegalese master across the checkerboard several times, as well as Mamina N’Diaye, the first African checkers player from Mali to enter the checkers game circuit in 1975.

He enjoyed playing this style of competitive checkers games as often as possible and was always seeking new competitors in order to obtain the highest possible result. Harm was challenged to improve his score with each simultaneous record of checkers match that was played. In 1975, Wiersma improved on Ton Sijbrand’s simultaneous record by playing against 187 opponents in one sitting.

Wiersma improves on Sijbrand’s simultaneous record of checkers games at Hierden 1975.
