Henry Despres played as 'Fianchetto1967' at chess.com...and formerly as 'chess2Knights'. I can't find any other account linked to him. Funnily enough his fianchetto account appears to be 'active', or at least not displaying any reference to being banned anyway.
I can't find it available online, but I found reference to, 'Study My Games to Improve Your Chess', 2010, by Henry Despres. It might even be a different Mr Despres but hey ho 🙂
