MI Oscar Castro 1953-2015

"Ha fallecido un ajedrecista que será recordado no solo por haber sido campeón de Colombia cinco veces, por sus triunfos sobre Petrosian, Geller, sino también por su filosofía de vida. Sus premios en efectivo le duraban menos de un día porque siempre los repartía en su entorno más necesitado; no tenía casa, ni ropa, ni propiedades, nada material porque llegara donde llegara, tenía amigos, orgullosos de tenerlo como invitado. Oscar Castro (1953-2015) que vio en el ajedrez solo arte y nunca nada más".
