I added a reference for J adoubovic although this could still use another reference or two A magazine reference contemporary with the incident as Bill suggests would be good This is an extremely well known story probably the biggest story at Sousse 1967 other than Fischer dropping out Unlike many such stories it seems to be true and accurately reported The WP BLP concerns are well grounded however and this really needed a better reference The article as a whole is still largely unreferenced The only other ref given is Golombek and Golombek has only a brief entry which does not support most of the claims in the article
