zanzibar: Many pictures of him can be found here:
<He was Arab Champion 1996 , and was a great attacker, and played most openings . He passed away after infected by Malaria on 27 October 2003, after playing in African Games - Abuja - Nigeria>

My preference would be to have his name spelled as <Essam> with two s's to match the above site, if this is the same player (which it must be).

Nigel Short, in his 2003-11-16 Telegraph article with notice of his death, uses the name <Esam Aly Ahmed> with one "s" as well.
