Whakaotihia te rerenga kōrero e whai ake nei: I whānau a David ki Milan i te tau 1970, ā, i te tau 1974 i neke atu ia me ōna mātua ki Luxembourg, i reira i ako ai ia ki te tākaro tēnehi i te tau i muri mai. I tutuki i a ia etahi angitu i te taumata taiohi engari kaore i te wa i oti ai ana akoranga rapunga whakaaro i Ranana i te tau 1992 i tiimata ai tana mahi taatai. I whiwhi ia i tana taitara rangatira nui i te tau 1998, ko ia te rangatira nui tuatahi o Luxembourg. I whakataetae ia mo Luxembourg i nga Chess Olympiads o 1994, 1996, 1998, 2000,
2002 me te 2006, e takaro ana i runga i te wa katoa. I te tau 2002 i wini ia i te mētara hiriwa takitahi me te kaute 84.6% (+ 10 <unk> 1 = 2). I te tau 2012 i whiwhi ia i te taangata Itari ka whakawhiti atu ki te Italian Chess Federation i te Hurae o taua tau ano. I whakataetae ia mo Itari i runga i te poari 2 i te 2014 Olympiad.
