"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".
